Most wireless antenna and wireless access point manufactures usually say the higher the better went mounting. This is true but you must take in account: coverage area, height of the building, type of antenna and weather.

Wireless Antenna – First you need to decide what type of antenna you are going to use. If you are going to use a directional antenna then you will be able to tilt it downward if needed to cover you needed area. But if you mount the antenna two high you will have a dead zone between the building or ceiling to the ground level. You will not want to tilt a omni directional antenna downward because you will be sending half of your signal up in the sky.

Another common scenario is to use a Omni directional antenna in conjunction with your directional antenna to avoid dead spots.
When choosing a directional antenna make sure it’s radiation pattern suits your needs. If you need to give a long hallway wireless coverage then you will need to ensure it’s radiation pattern doesn’t leave dead spots.

One 8dbi directional antenna could have a signal pattern of 60 degrees horizontal and vertical and a 14dbi could have a 30 degree signal pattern. If you used 14dbi directional antenna the room closest to the wireless access point could end up being dead spots.

Coverage Area – The most important thing is that you can provide a constant secure signal with out it costing too much money. That is really how you decide how to place your access points. Usually the higher the better because the height lets gives more options. Just take in account that you are not leaving dead spots close to the access point / antenna.

Low cost ISPs (Internet Service Providers) are a dime a dozen. You can find an ISP for as low as $7 per month or as high as $50 or more per month. These low cost ISPs may or may not be the right choice for you and your family. The way to find out is to compare the details of the ISPs such as email addresses, minute restrictions, access numbers, and track records.

Finding a low cost ISP should start with searching out the low priced ones that have a steady and consistent record with users. Ask friends and family for their advice and do research on the web to see which ISPs rise to the top of your low cost ISP search.

Access numbers will be an important consideration if you are using a dial up connection. Make sure your low cost ISP options have a local access number for you to use for your internet connection. If it doesn’t then you need to move on to another choice as long distance costs may override your savings on the low cost ISP.

Minute restrictions are a hot button topic when searching for a low cost ISP. Evaluate your internet usage for a few weeks to decide approximately how many minutes you use it per month. Many low cost ISPs have restrictions on the minutes that you can use per month. If you are a frequent user you will need to keep this in mind.

The number of email addresses should also be a concern of yours when choosing a low cost ISP. If you share your computer with family members or friends, then you will need more than one email account unless you want everyone reading each others mail. The number of email addresses should equal or exceed the number of people that will be using that email account.

Other points that you should check when choosing a low cost ISP is customer service response, software availability, and features. Call the customer service line and ask questions. This will give you a good idea of their availability and response. The software should be easy to upload or readily available for you to install their program. SPAM blocker and virus protection may not be available in your search for a low cost ISP. If these features are important to you, then you need to choose an ISP that offers these at a cost that you can afford.

Low cost ISPs may save you money in your budget, but be sure that they are worth the time and effort that they may cause. Disruptions in service or slow speeds may cause more time loss than money in your pocket. Weigh these issues carefully and you are sure to find a low cost ISP that works great for you and your family!

What is VoIP

VoIP is an acronym for voice over internet protocol, aka voice over ip phone. A VoIP, in essence, is a computer phone that allows you to make phone calls from your computer to anyone in the world, e.g., PC to PC, PC to phones – landlines or cells.

The voice signal converts to data packets and travels across the internet through a VoIP platform, and then converts back to voice at the receiving end of the communication exchange. Leading telecom experts are projecting that 75% of the world’s communications will be done on VoIP within the next several years.

What Kind of Equipment Do I Need?

You will need a computer with internet access and an inexpensive microphone if your computer does not have one built in. Although most VoIP voice over ip phone providers require high speed internet connections, there are a few that can be used on dial-up connections.

How Can I Place a Call or Receive a Call?

Basically, the same way you would a regular phone, except on your PC. When you download a VoIP voice over ip phone line on your computer, a phone usually appears on your screen. The computer phone acts like any other phone in that you can dial numbers on it from a pad, or click on a contact’s pre-programmed name, and press the call button. You will then hear the phone ringing to the party you have called and can talk to them when they accept the call.

When receiving a call, the phone will ring on your computer and you can click to accept the call and talk, or let it ring (based on the number of rings you have set up) and forward the caller to your voicemail.

What Kind of Features Does a VoIP Phone Have?

Typically a VoIP voice over ip phone not only has audio capabilities, but also three-way calling, text messaging, and contacts list. Some VoIPs even have webcam capabilities. In addition, there is usually a button to click that can indicate to others when you are available, unavailable, away, or off line.

Who Can I Call Using a VoIP Phone?

Most reputable VoIP computer phone providers limit PC to PC calls among their own subscribers for privacy purposes so that the quality of sound is not compromised.

Most reputable VoIP voice over ip phone providers have their own patented technology.

Some VoIP solutions providers require limiting PC to phone landlines or cells to their own subscribers, while others do not.

Advantages of VoIP

With VoIP computer phones, you have unlimited talk time to anyone in the world from PC to PC for a flat monthly rate

Most VoIP voice over ip phone providers offer drastically reduced costs for calling PC to landlines

Most VoIP’s offer reduced costs for calling PC to cell phones, however, prices often vary depending on the cell phone carrier.

Savings of up to 80% off current phone bills.

What are the Costs for VoIPs?

Typically there is an activation fee which varies between $20.00 to hundreds of dollars, although some are hidden.
Monthly fees, after enrollment, varies between $5.00 per month to $99.95 per month.
If you do not have a microphone on your computer, you would have to purchase one. Cost is between $5.00 to $40.00.

Things to Watch Out For with VoIP Services

Hidden costs

Unsecure lines – meaning anyone can listen to your conversation because of shared servers or open platforms, thus making you vulnerable to viruses, worms, Trojan horses, and unscrupulous hackers, which ultimately can corrupt your computer and create a costly computer crash.

Inability to be used with dial-up connections

Public listing of your name and/or phone number

Many VoIP services have spyware.

Wireless internet access is truly the wave of the future and depending on where you live the future could be now. Wireless “hotspots” really are popping up somewhere on a daily basis. Not that I’m complaining, because having the ability to access the internet via a wireless connection is a great convenience and allows you to “Take Your Laptop For a Walk on Wireless Side”.

On the other hand, even though there are thousands of “hotspots”, they don’t always get a whole bunch of publicity. However, if you were to do a search for “hotspots” in your town you may be pleasantly surprised. You may have thought that there weren’t any in your area but if you live in even an average-size city then it would be more of a surprise if you didn’t find a few “hotspots”.

Another alternative would, of course, to do a search for “hotspots” or “wireless hotspots”. There are a ton of websites you can go to and find “hotspots”. One “hotspot” that is generally considered to be on the most comprehensive is www.jiwire.com. You can search for local “hotspots” from the JiWire website or could simply type your zip code into Yahoo Maps and choose ‘WiFi Hotspots’ from the menu located on the right side of the screen.

Another option would be to check out the nearest Starbucks. They are literally everywhere and almost all of them offer wireless internet access in at some part of the store. Borders and Kinko’s are also pretty good bets and if all else fails… keep a watchful eye out for a local cafe or simply ask around a little bit and someone should be able to point you in the right direction.

Small Wireless ISP Fee

You may find that some of the larger hotspot networks with multiple, convenient locations require that you pay a small fee to a wireless ISP to access through them. In many instances, you can simply purchase a prepaid card at the place where the access is offered so it’s really not a big deal. However, if you want to free access your best bet would be to stick to the smaller independent locations.

Why Would a Cafe Offer Free Wireless Internet?

Actually, if you think about it, it’s really nothing more than good business. Rather than pay to access the internet in some dingy Internet cafe, you can access the Internet for free in their place of business and while there buy their food and drinks. Cafes are willing to pay the minimal cost of providing wireless Internet access in exchange for the new customers it brings into their business. Especially, in areas where Internet access is hard to come by, any other way. The same goes for hotels and airports: customers see wireless access as an added value and in many instances; they will choose a particular hotel based on this feature alone.

Actually, the real growth area in wireless “hotspots” is in the private sector. Businesses are falling all over themselves to provide free Internet access to their business customers – cafes, hotels and airports are all starting to offer wireless access to anyone who happens to be around. All you need to do is bring in your laptop with Centrino technology or a wireless PCMCIA card.

We’ve already covered a number of potential public hotspots to take your laptop and go searching for but one that hasn’t been mentioned is in reality may be one of first places to check out is your local public library. Public and university campus libraries are increasingly offering wireless access and if you’re a student there’s a good chance that your whole university campus is wireless enabled – or will be soon.

Hotspot Locator Software

Hotspot Locator Software allows you to create a database of known “hotspots” on your computer that you can search at any time, whether you are online or offline. Simple type in a zip code or the name of a city and the software will come back with the nearest “hotspots”… all sorted by distance from your location. And to make sure that your database doesn’t get out of date, each time you access the Internet the software automatically connects to its servers and checks the latest hotspot to your list and if your list if out of date it will download and update your list with the latest information.

If hotspot locator software sounds like something you’d like to take for spin, you’re in luck because it’s offered for free from many of hotspot providers’ websites. T-Mobile Hotspot is currently the largest provider and offers a free download at: http://www.tmobile.com/hotspot.

Broadband Internet access has redefined the boundaries of web networking. The time required to access the Internet, as well as to download information of different frequencies from the web, has been dramatically reduced. Web information is conveniently and easily accessible without being affected by long distances. Broadband Internet access is especially suitable for those who require instant and prolonged or constant (24/7) access to the Internet. Although it is a little more expensive then the traditional narrow-band Internet connection or dial-up network, the benefits fully compensate for the little price difference. A broadband connection ensures that the functioning of the cable and television line is not affected during connection, and vice-versa.

There are different types of broadband Internet access. The most efficient and reliable way it is accessed by home customers is through a cable broadband connection. This runs on an existing cable or coaxial connection. Another convenient way to access this technology is a DSL connection that uses an existing telephone line. Both these technologies are widely used by urbanites already having a telephone or cable connection. Most subscribers provide a 24-hour service for a flat monthly price. The T1 and T3 type of broadband connection is generally accessed by large business houses and universities. These oldest forms of broadband connections are the most efficient, but are also the most expensive. Access to broadband Internet connections is dependent on one’s geographical location. Although distance doesn’t usually affect speed and efficiency, the availability of infrastructure is a problem in remote rural areas and while one is traveling. Many of these difficulties have been addressed by the advent of satellite broadband Internet connections using land stations to receive land station transmissions. Wi-fi, or wireless broadband connection, is a revolutionary technology that promises to remove the restraints of distance, time and location. It allows one to access the net even in mid-air. Technology and special programs have made broadband Internet access viable for senior citizens or people with special needs (deaf or blind).

Broadband Internet provides detailed information on Broadband Internet, Broadband Internet Access, Broadband Satellite Internet, Broadband Internet Providers and more. Broadband Internet is affiliated with Broadband Speeds.

DSL or Digital Subscriber Line is a type of broadband Internet connection. This type of broadband Internet requires you to have a phone line. Unlike dial up, you can actually use the phone while you are connected to the internet.

What are the benefits of a DSL Internet connection?
DSL allows you to have faster internet connection than a dial up. It can offer faster access to information, faster downloads and much more.

Here are some of the benefits you can get from a broadband DSL Internet service.

Unlike dial ups, DSL allows a subscriber to make and receive phone calls while having an active internet connection. Dial up internet does not allow this, if someone calls you, your phone line will be busy. A DSL line also keeps your computer online as long as your computer is turned on.

With DSL you can talk to your friends, family or business associates with a web cam in real time. You can easily connect a microphone, web cam on your computer, and start using these accessories right away. This may be possible in some dial up, but since it has low speed, the data sent and received will usually be delayed or choppy.

Since you can actually use your voice in the internet in real time, you no longer need to call families and friends using expensive long distance calls from your traditional phone.

DSL also enables you to use VoIP technology. This technology virtually replaces your traditional phone with the internet. VoIP has free features your traditional phone company consider as additional features and chargeable.

Video Conferencing
Caller ID
Call Forwarding
Call Transfer
Call Waiting
Ringtones
Voice Mails
Free Long Distance Calls

These are just examples that VoIP offers and a lot more features are available.

Since you can conduct video conferencing, you no longer have to travel to meet with your business associates, therefore, saving you from travel expenses.

Another benefit from DSL internet is that you can play audio and video streams in the internet smoothly and without interruptions. You can now play your favorite internet radio stations while you surf the web or play your favorite music videos in the internet.

Playing online games that requires high-speed internet is now possible with the DSL internet. You can use your own PC or gaming consoles such as the PS2 or Xbox to play with other people from around the world and create an online community with adventure games.

Students can also improve their studies by using the DSL connection. Since DSL provides high-speed internet connection, students can now research more webpage that are required for their studies.

In dial ups, low speed internet connection restricts a student’s research to just a few webpage. This is because in dial up, loading webpage is too slow that a student will just stick to one or two websites to save time and money to do their research.

Online businesses can update their websites much faster in DSL than in dial up. Updating website for online businesses is crucial to inform their customers about the products they are selling.

Today, there are many DSL service providers in the market; choosing one is up to you. Research about the companies that provides this service before you buy their service and you can be sure about the quality of the DSL connection.

Ask your friends and family first who have this technology in their homes or businesses can also help you choose which DSL provider you want to work with.

Bob Hett has extensively covered the Internet Service Provider industry as an analyst and has researched the various companies for factors based on price, reliability, support and overall quality. Learn more at DSL Internet Service

A circuit in an ADSL is defined by endpoints. A route is defined as the path that is taken between these endpoints. Switching is the process of making a path available for use by a circuit. A router shifts data from one route to another. It also allows for access to various fixed or temporary routes. This they do by recognizing the specific destination address and then copying data from one route to another.

Routers are useful when there are multiple networks. Routes may be permanent or temporary. There are several functions of the router. Routers must essentially contain the address information that is associated with each individual packet. This information can be in the form of full origination and destination information for each packet, or a special identification set up for a particular origination or destination on a temporary basis.

Routers will contain the address tables or a routing directory. This routing directory enables routers to identify and define the path for travel of the data. In a scenario where User A and User B are located on the same LAN, the router does not do anything except examine the packet. If User A and User B are located on different LANs and the router has a node (a direct connection) between the two LANs, then the router also has very little work to do. In this case, the LAN grabs a copy of the packet from the first LAN and puts it on the second LAN.

ADSL routers are particularly useful when they need to access WANs. Consider a scenario to understand the process better. If the User A wants to communicate with User B, where User A is on LAN 1 and User B is not on a LAN, then in this case the router on LAN 1 will make a connection through a WAN to User B, and provide a temporary access route.

When it comes to choosing a broadband internet connection, you only have three major options to choose from, cable, DSL, and satellite internet. Of the three, cable and DSL are the fastest, but they are not portable, and they are not available in most rural areas. However, satellite internet service can be had almost anywhere in the northern hemisphere where you have an unobstructed view of the southern sky, and in some cases you can even take it with you as you travel.

So how does satellite internet service work anyway? Well, the internet data is transmitted to a network of satellites that orbit high in our earth’s atmosphere. From there it is beamed down to be received by those who have the necessary equipment to be able to decode it and display at on their computers. So in order to receive satellite internet service, you will need to have a satellite dish, and modems for both uploading and downloading data from the satellite, as well as a capable computer system.

Because high speed satellite internet service is not dependent on cables or wires it can be received almost anywhere, and therefore it makes an excellent choice for those who live in rural parts of the country, or those who live in areas where cable and DSL are not available, and who want to take advantage of a high speed broadband internet connection.

Although satellite internet service is much faster then dial-up, in fact almost ten times as fast, it does not approach the ultra-fast speeds of both cable and DSL service. So if cable and DSL are available to you, either one of them may be a better choice for broadband internet access. However, in the absence of either cable or DSL, satellite internet service is much more preferable then dial-up.

Another great advantage of satellite internet service is its portability for people who are always on the go and travel a lot. For instance, many RVers make good use of satellite internet in order to have a high speed web connection pretty much anywhere they go across the country.

There are generally two options for these kind of travelers, either tripod mounted satellite dishes, or vehicle mounted units. Actually, either one can work very well when correctly set up, but the tripod mounted dishes provide much more flexibility for location of the dish, and they also cost quite a bit less than the vehicle mounted units when initially purchased. There are several companies that now have this kind of equipment available for sale, and they can be found very easily by making a search on the internet.

As you can see, there are a lot of reasons why satellite internet access can be a good choice for many consumers, but there are also drawbacks that must be considered as well. Hopefully, the information that we presented in this article can help you make an informed decision before you buy satellite internet services.

Steadman Issenburg writes on many consumer related topics including communication. You can find broadband satellite internet services and info on satellite internet speed and more by visiting our communication website.

Are you shopping around for high speed internet and getting totally confused? $12.95 for 6 months, or $14.95 for 3 months? Upload speeds of 128 kbps or download speeds of 768 kbps? What does kbps stand for anyway? Hopefully this article will help you make some sense of all the promotions out there.

I compared the promotions (as of May 2006) being offered by most of the primary DSL and cable modem providers in Southern California. It’s hard to fit a giant Excel spreadsheet into a text article, but see if you can use the information I provide to at least try to compare apples to apples. The two main criteria I focused on are price and speed.

A few points to clear up first so you can be more educated in your choices:

kbps: kilobits per second

mbps: stands for megabits per second. A megabit is 1,000 times faster than a kilobit. So 1.5 megabits is equal to 1,500 kilobits.

download speed: The download speed is for downloading web pages, software, etc. and is what you probably use most of the time.

upload speed: The upload speed is used, for example, when you might upload photos to the internet (for instance to Snapfish or sending an attachment to an email), or if you have your own website and upload your own pages.

Since you are only downloading most of the time, high speed internet companies focus primarily on download speeds, which are invariably faster than upload speeds. You might want to focus primarily on download speeds as well, depending on your type of usage of course.

Also, the general consensus is that the typical download speed for home DSL (before all these promotions started coming out recently) is about 1.5 kbps. So it is worth a word of caution that the cheapest promotions may or may not be the best for you.

Several companies are offering very good prices for 768 kbps of download speed. I have been told that this speed is adequate for people who mainly use email and do light web surfing. So you have to think about how much you use the internet. Do you download music? Are you a web surfing addict?

One thing I’ll tell you is that if I, as a computer consultant, had an internet speed of 768 kbps, I’d probably be rather unhappy. But if you’re a light user, you’d probably be fine.
OK, now you can read about the different offers and see for yourself:

AT& T (formerly SBC):

Their lowest promotion prices are $12.99 per month and $17.99 per month. You also have to pay a $12.95 shipping and handling fee. (And you have to pay $49.99 up front for a modem, but you get a mail-in rebate of $49.99 as well.)
The $12.99 price is for download speeds of 384 kbps – 1.5 mbps. The $17.99 price is for download speeds of 1.5 – 3.0 mbps.

Those prices are good for a 1-year contract, but beware. If you don’t call AT&T before the year is up (I believe they send you a letter to remind you), the price goes up to $50/month. Once you call, though, AT&T will offer you whatever promotion they have at the time. There is a $99 termination fee if you break your 1-year contract.

Summary of AT&T prices:
Lower speeds: $12.99
Faster speeds: $17.99
Other fees: $12.95 shipping and handling,
$99 termination fee.

Verizon:

This company is offering a base price of $14.95 for download speeds of up to 768 kbps and upload speeds of 128kbps. The first month is free, however there is a $19.95 shipping and activation fee. This $14.95 offer is good only if you order via the internet though (a little Catch 22 there). If you call and speak to a live person instead, it’ll cost you $17.99 a month. Ha!

For heavier internet users, Verizon has another, slightly more complicated promotion. For download speeds of up to 1.5 mbps, you get the first month free. Butttttt, for the second and third months it will cost you $21.95, and $29.95 for months 4-12. (Where’d they come up with that plan?) Upload speeds are about 384 kbps.

These Verizon promotions come with one-year contracts and a $79 termination fee if you break it. You also need to call before your term is up to get decent rates for the next 12 months. (for the second offer you can stay at $29.95.)

Summary of Verizon prices:
Lower speed: $14.95
Faster speed: $21.95-$29.95
Other fees: $19.95 shipping and activation fee.
$79 early termination fee.

AOL:

AOL doesn’t have its own high speed infrastructure per say. It provides AOL service but uses AT&T or Verizon to deliver it in the Southland.

The price is $25.90 per month for a one-year term. After that year, Verizon customers are still charged $25.90 per month, while the service with AT&T goes up to $29.99 per month. The speeds are generally 768 kbps for download and 128 kbps for upload. With Verizon there is a shipping and handling fee of $19.95 and a $79 early termination fee, just as if you’d went with them without AOL. AT&T (as shown above) asks for a $99 early termination fee.

Summary of AOL fees:
$25.90 for 768 kbps download speed
( for other fees see AT&T or Verizon fees.)

Earthlink:

Earthlink: This company is offering a promotion of $12.95 for the first six months in certain regions of the country, with a price of $29.95 after that. This promotion is for decent speeds: 1.5mbps for download speeds and 128 kbps for upload speeds. They also charge a $19.95 shipping fee, and $149.95 if you break your 1-year contract. (So I’d guess you’d better be sure you want to stay with them!)

Summary of Earthlink prices:
Faster speed: $12.95-$29.95
Other fees: $19.95 shipping fee,
$149.95 early termination fee.

DSL Extreme:

DSL Extreme offers a promotion of $12.95 per month for customers with SBC phone service. That promotion offers speeds ranging from 384 kbps – 1.5 mbps for download, and 128 – 384 kbps for upload. Those with Verizon can expect to pay a little more, $14.95 per month. Speeds with Verizon are 768 kbps for download and 128 kbps for upload. These prices don’t include $15.43 for the shipping and handling of the modem.

As with the others, you’re in for a 1-year contract. But if you renew before it expires, you can lock in the price DSL Extreme is offering returning customers at the time. That price is not yet determined:

Watch out, though. The early termination fee if you decide to end the 1-year contract is a whopping $250!

Summary of DSL Extreme prices:
Lower Speeds: $12.95-$1495
Other fees: $15.43 for shipping and handling of modem,
$250.00 early termination fee.

I also talked to a couple of companies that offer cable modem:

Comcast:

The prices for cable modem tend to be a bit higher, but the two cable companies I called offered faster speeds than the DSL promotions I looked at.

Comcast is offering a promotion of $26.95 for the first three months with download speeds of 4mbps and upload speeds of about 386 mbps. But after your honeymoon the price goes up to $45.95 if you have cable TV with them or $56.95 if you don’t. One good thing – there is no contract, so that means there’s no early termination fee.

You also have to either buy a cable modem at an electronics store (Comcast doesn’t sell them) or rent one for $3 a month. So be sure to include that fee in your calculations!

Adelphia:

To begin with, Adelphia offers a basic package which happens to be very basic. Both its upload and download speeds are 256 kbps (kinda slow if you ask me). This package’s price is $24.95 per month.

The company also offers a more reasonable package that costs $24.95 for the first three months, then goes up to $43.95. The speeds with this package are pretty fast – 4 mbps for download speeds and an upload speed of 384 mbps.
As with Comcast, Adelphia’s packages are month-to-month, with no contract and no termination fee. But, also like Comcast, you have to either purchase your own modem or rent one for $3. Also, you don’t need to have Adelphia TV cable service to get those prices. The prices are the same for both cable TV and non-cable TV customers alike.

PoE gives you the freedom of installing wireless access points anywhere a ethernet cable will go. Before power over Ethernet was available a wireless access point always had to be near a power outlet to give it power. This meant more money and usually bad placement.

PoE uses a device called a power injector to transfer the correct amount of power required to run the wireless access point. PoE uses the two unused wireless in a Ethernet cable to run the power. Gigabit Ethernet uses all the wires in an Ethernet cable thus PoE is not available for Gigabit Ethernet. Each client device that meets the standards of the PoE 802.3af amendment will be assigned a power class of 0-3 which will mandate how many watts they need. Often your wireless access point will be managed by a switch that will double as a PoE injector.

Wireless access point placement is a major key for good security, both physical and wireless. If you are using a Fat access point which is located near a common power outlet or easily in reach of employees all it takes is a paper clip to reset the access point and your network has been hacked. Also placement is a major concern because if you install a wireless access point on the perimeter walls of you office you have just sent half you signal out side to the war driver passing by.

Remember when coming up with your wireless network budget do not let anyone say we don’t need PoE. Compromising on placement of your access points will cost you security and money in the long run.
