Dial up Internet access is an inexpensive but slow form of Internet access in which the client uses a modem connected to the computer and a telephone line to dial the Internet service provider.

By configuring the computer to dial a specific phone number, the computer is granted Internet access. It is usually the only choice available for most rural or remote areas where getting a broadband connection is impossible due to low population and demand. It may also be an alternative to people who have limited budgets.

To use dial-up access, the user must have a telephone modem, a device that connects a computer to the telephone system and is capable of converting data into sounds and sounds back into data. The user’s ISP provides software that controls the modem. Upon joining a dial-up service, the subscriber chooses a username and password.

Due to the limited bandwidth, the ability for the modem to send and receive data, dial-up service can take up to five minutes to download just one megabyte of data. In some cases, caching frequently visited pages, and other software tricks can speed up the experience of dial-up access in some cases. If your work online is multimedia-centric, (music, movies, and graphic-laden websites), dial-up service may be too slow to meet your satisfying levels.

Dial-up connections usually have high latency which can make online gaming or videoconferencing difficult. Gamers with dial-up connections are often disconnected from game servers due to high latency of the connection. The factors to consider while choosing a dial-up Internet Access Provider are coverage, price and customer support.

The advantage of dial-up access is that its much cheaper than cable and broadband Internet. Obviously, speed is a disadvantage of dial-up access.
The speed of dial-up Internet is slow because of text, graphics, connection speed, traffic, and the particular site one is visiting. Another thing is the loading speed, which may vary depending on the type of modem one is using. A higher speed modem may increase surfing speed, however, the quality of the phone line one is connected to can also make a difference in the speed.

Despite the above disadvantages, at places where the facility of broadband is not yet explored, dial-up is the only inexpensive means of using the Internet.

VoIP technology is revolutionary in that it combines internet access with telephone service therefore utilizing the same technology for two very different things. Now, instead of having a traditional phone connection, VoIP technology enables you to use your internet broadband connection to make telephone calls.

1) So how does a VoIP phone work?

Firstly, you need a broadband connection and a router. This device works by allowing you to take phone calls as before. However, with a VoIP phone, the connection is now digital instead of through a phone line. A VoIP phone also has a gateway that connects you to a network. Your voice is then converted to a digital sound and this information can be sent in packets enabling you to have great sound and connection to people with and without the VoIP service.

2) What do you need to get started?

Of course, you need a broadband internet connection. Although VoIP can work with other internet service providers, the voice reception quality will not be as it would be with broadband.

3) What are the benefits of a VoIP phone?

The main benefit is that the VoIP phone costs much less that the traditional phone lines. This applies whether you use a cell phone or home phone service. Unlike home phone services, regular long distance callers really notice the benefits of a VoIP phone. The more long distance calls you make the more you save since with a VoIP phone the location of the caller and the person receiving the call is not important. Since you are also able to take you adapter with you, this service is perfect for the travelers among you. VoIP phones are also cost effective if you wish to add to your service. For example, instead of the normal fee of adding a phone line to your traditional home service, you need only pay a minimal amount since those with VoIP phones need to install any additional equipment.

4) Are there any disadvantages of switching to a VoIP phone?

Although there are some disadvantages, however these are minor. Poor voice quality can occur when the reception is poor. However, this is something we already have to contend with cell phones. Also, since a VoIP phone is connected to a broadband connection, if the company supplying you with this connection has any problem with its power supply, then your call will automatically be cut off. This may also occur when there is poor signal in an area.

5) What are the future applications?

Presently, the majority of companies allow you to be online at the same time as making calls. There are no limitations to this service and in this area can only grow and progress in the future. VoIP phone use will become more and more common and easier to use, as digital phones will be made. This means that a customer no longer needs a router and this will lead to VoIP phones becoming more popular than the traditional phone line.

Dial up ISP service is the cheapest choice of any of the ISPs and may be a good option for that family on a tight budget. The software upgrades have definitely increased the speed of dial up ISPs, but their speed is still slower than some other options. Dial up ISP service can be purchased from several different companies including Earthlink, AOL, Juno, and others.

One of the major issues with dial up ISP service is how long it takes to connect to the internet and disruptions in your connection. Depending upon the time of day and your company, connection can take anywhere from 30 seconds to two to three minutes or longer. Disruptions occur when you lose contact with the provider because of phone line static, storms, or problems at the providers end. This can be very irritating if you are working online or researching and have to keep reconnecting to the internet.

When choosing dial up ISP service, choose a company with a long track record and software upgrades rather than the newest, cheapest service on the market. Cheaper does not necessarily translate into better, especially in an ISP service. Read the fine print of your policies. How long can you stay online before being cut off? How many email addresses are allowed per account? Is there a limit on the number of hours a month you can be online without additional charges?

Access numbers are a necessity for dial up ISP service since you use the phone line to connect to the internet. Ensure that there are local access numbers for your use so you will not have to pay long distance charges. If you travel, do they have access numbers in a wide variety of locations or, even better, a toll free number for connection?

What comes with your dial up ISP account? Do they offer SPAM blocker or virus protection? These are important tools for your internet experience and your computer. SPAM blocker helps to block some of the unsolicited email that you get from sellers and different companies. Although it does not block all of it, it will make a large difference in your email. Virus protection is something that no computer user should be without. It scans incoming email and downloads for viruses that may harm your computer.

Dial-up ISP service is a great choice for budget minded people. Although the connection is slow and websites may be slow to load, the cost difference may be more important to some consumers. Think of it like this, if you have dial up service, then while websites load you have time to clean the house and balance your checkbook!

High Speed Internet Advantages

DSL is just one of many ways to connect to the net. There are many advantages DSL has to offer other forms of Internet connection. One of the most obvious advantages is DSL offers a fast connection. Rather than wait hours for a document to download using dial up, with DSL you can download large files in just minutes. Here are some other advantages DSL has to offer high speed Internet fans:

DSL allows you to use an open Internet connection and use your telephone line for phone calls at the same time.

DSL speed is typically a lot faster than a traditional modem and doesn’t require new wiring. In fact you can usually use the phone line you already have installed in your home to get DSL up and running.

Most companies provide you with a DSL modem during installation as part of the DSL package.

If you own your own business you’ll be able to upload and download large files much faster using a DSL connection.

Disadvantages of DSL

Of course, there are disadvantages to anything as is the case with DSL. While most users consider these disadvantages minor they are nonetheless worthy of note:

The closer you are to the central office of the DSL provider the better your connection will work. Thus if you are located far away you may have more trouble connecting using your DSL line.

Typically connection speeds are faster when receiving information and data than when sending data using a DSL connection.

Organizations in our region have been steadily adopting wireless networking over the past few years, and many more businesses will take the leap to wireless over the course of 2006. By implementing a wireless network, your employees can do their job more efficiently and be more productive. For just about every business, there is an opportunity to use a wireless network to become more competitive in the marketplace.

Many businesses have installed wireless access points (WAPs) in order to realize various benefits, but my experience has shown that relatively few organizations understand the importance of properly securing their wireless network. If an attacker gains wireless access to your network, they are behind your firewall and there is very little protection available to you. It is not uncommon to find unsecured networks in our region, and I frequently see access points in use that are not up to today’s security standards. When you add in the number of improperly configured WAPs, it becomes apparent that our region has a lot of room for improvement.

When evaluating your need for wireless security, you should ask yourself these four questions: How valuable is your data and how sensitive is it? What regulations are your company obligated to meet regarding data privacy? How much traffic passes by your office? Are there any potentially attractive targets near you? In many instances a company’s wireless security policy is like failing to have a front door to your house. Anybody walking by can peek in to see your valuables, and easily walk in to take whatever they want.

I won’t get into the technical aspects regarding how wireless networks can be attacked and the methods that can be employed to make them more secure, but I can offer an overview of the three wireless security standards and how they compare to each other to give you an idea of where you stand. Just compare the information present on the access point, its original box, or the manufacturer’s web site to learn what your WAP is capable of.

The first security standard developed for WAPs is known as WEP (wired equivalent privacy). Older WAPs and less savvy network administrators will employ this method for protecting a wireless network. A pre-shared key is the best defense of WEP. Most people do not change the WEP key frequently which is like having the same password for all users on your network. WEP can be easily defeated by an inexperienced hacker using simple tools, making this a poor security choice. If your access point is more than two years old, it probably uses WEP and should be replaced immediately. Using the front door analogy, WEP is like locking your screen door, and giving every person who visits the house a key. People can easily peek inside, too many people have a key to open the lock, and an intruder could just cut a hole in the screen to unlock the door from the inside.

To address the problems inherent with WEP, the wireless industry developed a standard known as WPA (Wi-Fi Protected Access). WPA requires the use of passphrases (long passwords), and a unique encryption key for each user that frequently changes. Other technological improvements were made to improve security, as well. WPA was designed to be backwards compatible with WEP access cards, giving administrators an affordable upgrade path to improved security. WPA is like installing a solid front door to your house, and using the lock on the doorknob. Intruders can’t peek inside and it is more difficult for them to gain entry to your house.

WPA has not yet been hacked, but it’s only a matter of time. To address this reality the wireless industry has just released the WPA2 (Wi-Fi Protected Access 2) standard, sometimes referred to as 802.11i. WPA2 improves upon WPA by adding user authentication with a server and using stronger encryption. Windows XP just began supporting WPA2 in May. A properly configured WPA2 network satisfies US Government security standards, making them a necessity for regulated businesses in the medical and financial industries. WPA2 protection is like using the deadbolt of your door and an intercom to verify the visitor’s identity before letting them inside.

If you are about to purchase a new access point, it should definitely support the WPA2 standard. If you must to use a WAP that utilizes WEP or WPA standards, there are still methods that will help you create a more secure network. Getting the most out of an inferior technology is sometimes better than failing to properly use a new one. For specific information on securing your network, give me a call and we can develop a security policy created to meet your individual needs.

VOIP technology is on the rise and major corporations are transferring their business needs over to VOIP and houseolds worldwide are also switching to VOIP. VOIP is produced by transferring voice into digital data over the Internet. You can use VOIP only if you have high-speed broadband connection at home. You then need to purchase an equipment called VOIP phone adapter to use VOIP. The phone adapter will allow you to use all your telephones with VOIP technology. Also you may have to purchase a router. Most of the VOIP providers will supply you with the hardware that is required. You can even purchase phones designed for VOIP.

With VOIP becoming the wave of the future, major companies have started to integrate VOIP with instant messaging programs. If you are ready to enjoy unlimited long distance calling and lower monthly phone bills, a good idea is to make a list of your needs, wants and features in a phone, compare plans and choose the service provider that best fits your needs. If you are still unsure whether VOIP would be right for you, consider its benefits.

VOIP is cost efficient

VOIP is cheaper than other telecommunication applications. You can use VOIP to reduce cost on long distance and local telephone calls. Many VOIP providers have plans that allow unlimited local and long distance calling.

VOIP integrates your audio, data and video applications
VOIP systems can incorporate your telephone needs with your computer applications such as email, fax, web conferencing and videophone needs. This saves time and energy by combining all of the services into one basic application.

VOIP provides flexibility

VOIP users can take their phone adapters with them, use their telephone number anywhere they have an access to an Internet connection and enjoy the advantages of a VOIP technology. If you have high-speed Internet connection, you can take calls on your regular number.

You can choose your own area codes

This is a fantastic option for those whose friends and family all live in one particular location and they are outside your current state of residence. By choosing your family and friends’ area code you are allowing them to call you, whenever they want to and they will not have to pay long distance charges.

Free features

Some features are bundled with VOIP having unlimited calling plans. These features include voice mail, call waiting, call block, and call forwarding. With VOIP, users can practise great control on all of their phone features as well as save on charges.

As VOIP technology is advancing, new accessories in VOIP like VOIP headsets, VOIP headphones are coming in the market.

We have all come a long way from connecting to the internet via the old 2400 baud telephone line modem to a slow AOL connection. Now, there are many ways to connect to high-speed internet at various costs and service levels. Today, the Cable TV provided high-speed internet access usually costs about $50 per month in the United States and provides speeds from 1 megabits per second to 3 megabits per second (in some locations). The baby bells have also jumped on the high-speed internet service bandwagon, with various DSL service offers. The DSL service is delivered to your home or office over a standard telephone line, and the cost can be as low as $25 per month for high-speed access.

The best thing about high-speed internet service (other than you don’t have to wait forever for your favorite web page to load) is the option to connect other users to your same internet connection – and share the service. There are two ways to share an internet connection – either hard wire network (using twisted (4) pair Cat 5 wire), or Wireless network. The old-fashioned hard-wire method is still the best for constant connectivity and security. With a hard-wire network and the correct security precautions, it is very difficult for a hacker to access your network from across the street! However, wiring your house or small business for hard-wired internet and network access can be a big job with big costs, and your computer is “stuck” in one location near the wire outlet. Today the wireless network solutions from Linksys

Broadband can enter the home or office through either an ADSL connection or via a cable. An ADSL connection is provided by an ISP and connects with the Internet through a normal telephone line. A cable connection is provided by a cable company and a separate cable needs to be installed, through which phone, television, and broadband services are provided.

The ISP will usually supply their customers with a USB modem to go with their ADSL broadband connection. A USB modem allows a single USB equipped computer to access the Internet through the ADSL connection.

If the user wishes to connect more than one computer to the Internet through the ADSL connection at any one time, they will require an ADSL router.

An ADSL router is a device that connects two or more networks together. In this case the network of computers located within the home or office is connected to the Internet, which is the largest network in the world. The home or office network is a called a Local-Area Network (LAN), while the Internet or any outside network is called a Wide-Area Network (WAN).

An ADSL router is therefore used to connect multiple computers within a home or office network to a single broadband connection, which is used to access the Internet.

One of the most important additional features that can be added to an ADSL router is the ability to go wireless. An ADSL Wireless Router can provide the same networking ability as a normal ADSL router without the need for wires and cables running between the devices.

Instead of using cables, wireless devices connect to each other via radio waves through a device called an access point. An ADSL wireless router provides the access point necessary for the wireless network.

As well as acting as an access point, ADSL Wireless Routers have built-in modems to allow users to connect to the Internet directly through the phone line, without the need for a separate ADSL modem. In fact an ADSL wireless router contains a router, modem, switch, and an access point within the same device.

The router allows the devices to connect to the Internet, while the switch provides the ability to connect wired devices together, and the access point allows for the networking of wireless devices. Therefore an ADSL wireless router allows for the compilation of a network that can be either entirely wireless, entirely wired, or a mixture of both.

Devices that connect to the ADSL router through wires will require network cards. Devices that utilise the wireless capabilities will require a wireless network card in order to send and receive radio signals to the ADSL router via the access point.

This is basically a system to locate the handheld when making a call to 911. In the mid to late 1990’s, many people got cell phones just for the emergency use of being able to call for help almost anywhere. The problem came up when statistics showed that almost 92% of all serious 911 calls, (where the person was just barely able to make the call), they either didn’t know where they were or was unable to tell the 911 operator where they were, or they might not have been able to talk at all. This caused a big concern, 911 operators couldn’t do anything but listen to the person on their cell phone as they pass away. The Location Sensitivity system still doesn’t work if you are in an area that only has an analog signal. (Which is the older cellular system of the mid 1990’s and earlier). Most metropolitan areas and all interstate freeways are covered by the newer digital service. It’s just when you get out in the middle of no-where, you might end up with an analog signal. Most phones will display the letter “A” in the top right or left corner when using this system. Check your phone documentation, some phones don’t even have this capability. Which means if you get into one of these areas, you can’t make any type of call what-so-ever.

Soon, the Location Sensitivity feature will probably be offered by the cellular companies as part of their pricing plan. Some carriers like Nextel are already taking advantage of this new technology by giving customers a GPS location service along with their calling plan. If you don’t have this option with your carrier, and you have a Smartphone you can always purchase one of the SD slot GPS units that works with mapping software. The program I’ve really enjoyed is Mapopolis, which works great with most of the popular GPS hardware available. And most even have a voice activation that will tell you where to turn, which is directed through the speaker phone portion of the Smartphones. The ability to have GPS information and mapping on your handheld will be a great plus while traveling.

Back to the Location Sensitivity. I’m just wondering how much the cellular companies are going to charge for such a GPS type service!? I’m sure they’re all working hard right now on the new pricing plans that we’ll have to pay if you don’t have the GPS hardware to install on your Smartphone.

When these services become available, they will only be location based. Another words, most GPS’s these days will actually give you your current altitude and most have a pretty fast refresh rate. The refresh rate is the time between position updates. An example; If you have a GPS in your hand that refreshed three times per second, this would be a very acturate reading. Even if you are driving at 70 miles per hour, the moving map on the GPS will be able to keep up with your actual location. That’s an issue the engineers are dealing with on the Location Sensitivity system. It wasn’t designed to have any type of refresh rate at all. Once a position has been found, it never was designed to refresh that position. (I guess if you are hurt, and you called 911, you aren’t supposed to be moving. Hmmm, So if you fell off a bridge, and landed in the back of a truck driving down the interestate, I’m not sure if they would be able to locate you. They would know where you were when you first dialed 911, but as your location changes, they might not be able to find you). Supposedly, the 911 operator can pull a refresh, this would at least tell them the direction the vehicle is moving. But to locate you while you’re moving, might be more difficult than anyone had expected.

Another problem with many of the handheld units, the actual speed of the processors within them. Most cell phones operate on around 1 to 2 MHz processor speed. Most Smartphones operate anywhere between 30 to 500 MHz. (Most new home computers are operating between 2 to 4 GHz processor speed, just to give you an idea). This is where the engineers are running into the biggest problem with creating a GPS refresh rate. The processors in all handhelds will just have to be faster than they are today. And like all of our other technolgies, I’m sure this won’t be a problem very much longer for the designers.

Hmmm, soon we’ll have Pentium 9 cellular and Smartphones running at 8 GHz processor speed! You know it’s going to come to this, and it’s not that far away.

Let me ask you a question: How much is your computer worth when you or your employees are sitting in front of it? Now, how much is that same computer worth when you or your employees aren’t sitting in front of it?

When you’re out of the office and that potiential client calls, do you have to tell them that you will get in touch with them when you return to the office? Is that potiential client calling your competition in the mean time to see if they get a better response? What if you could have all your important files with you 24 hours a day, 7 days a week? Hanging on your belt or sitting in your purse, and it wouldn’t weigh too much more than the cell phone you are currently carrying.
