You Had Me At EVDO

By: Russell Snapper

I have been having too much fun, so now is the time to get a little technical. The ironic thing is that today’s more technical comments are about technology that is meant to allow people to have a lot of fun on their mobile phones and waste tons of productive time just watching movies and TV from their phone. We have come full circle. Cell phones originally were developed to allow people to be more productive and now they will allow people to screw around anytime, anywhere. That is progress!

What Is EVDO?

EVDO is short for “Evolution, Data Only” although sometimes referred to as “Evolution, Data Optimized”. EVDO is a highly adaptive standard for wireless broadband that has been introduced to improve the performance of 3rd generation, 3G, mobile Internet access.

Wireless broadband has its obvious advantages over standard, hard wire broadband connections and the most pertinent of these advantages is the mobility of the broadband device. By using wireless Internet connections it has been possible to access the Internet using not only notepad computers but also cellular phones and other mobile devices.

The Advantages Of EVDO.

While mobile Internet access has progressed, the existing standards do have limitations. The bandwidth is limited and subsequently only comparatively small amounts of data can be transmitted to end-users without a loss of performance and quality. EVDO is unique in its approach to try and counteract this. Complex mathematical formulas are used in order to assign a unique signature to every mobile device. Once this device sends a signal requesting data transmission, the signature is applied to the signal and the altered message is sent. The receiver uses the inverse of the equation to convert the signal back again. EVDO also breaks data down into smaller packages of information and sends these packages separately. In essence this means that the bandwidth usage from any single device is cut down massively, allowing for many other users to gain high speed Internet access through any mobile device. It also means that in total less information needs to be sent. Without the use of EVDO, mobile devices struggle to gain the bandwidth they require in order to seamlessly log onto websites, especially if those sites have a lot of data to send. With EVDO this basically becomes a thing of the past and millions of people on their cell phones can access the same sites at the same time with little or no effect.

EVDO Performance.

EVDO can potentially produce a 2.4-megabit throughput. This is as powerful as a great many American DSL broadband connections found in people’s homes. Of course, because EVDO is truly wireless and portable it doesn’t matter where you are, you can access the Internet on your cell phone, your notepad or any mobile device without fear of poor quality.

The Existing Technology.

EVDO has been introduced to compete with existing wireless Internet technology called W-CDMA. However, W-CDMA requires a permanent path to be created between receiver and transmitter, unnecessarily using vast amounts of the available bandwidth. EVDO does not require this because it creates packages and sends the information in smaller parts. One of the big advantages of introducing EVDO, though, is that it uses exactly the same frequencies as existing methods, meaning there would be no structural change required to establish a usable network.

EVDO Service Providers In America.

Korea and America are leading the way in introducing EVDO to personal users and several services in the US are already operating several pricing and limit plans in order to allow users to easily access an effective Internet connection over their cell phone. Amp’d is one of the more recent plans to enter the market and with a service costing $15 per month for an all-inclusive EVDO package, they look to be leading the way in pricing as well. The Amp’d service provides a wide range of MTV provided channels and media for you to download, if this is the package you choose, and there is sure to be something for everyone’s tastes. Verizon and Sprint also offer EVDO capable phones, which could be worth the look if you are looking for something more than the ‘extreme’ entertainment channels that Ampd Mobile offers.

Routers - Uses And Various Types

By: Pencil Writer

Router is a hardware which is used for sharing internet access through sharing networks within local area. These routers have designed with the potential to transfer signals from a single point to the multiple exact destinations. It is essential to get a router for sharing your application and internet within your LAN. While you choose a router, it is better to keep certain considerations like modems, types and the budget.

Types of Routers

Cords are used for getting connectivity. The wiring process and maintenance of cords are not easy. Routers can be classified in to two namely cable routers and wireless routers. When you use routers for sharing internet from a server to multiple client systems, it is essential to consider about the usage of cords.

Corded Routers

When the necessary cords are already placed properly with the systems, there is no need of buying wireless routers. Corded routers can offer high quality data transmission. If the cords are placed very close to each other, you can save the length of the cable as well as money. Before using the corded routers, it is essential to check the specifications. Therefore you can make sure the ability to share web access in your office or home.

Wireless Routers

As these routers do not use cords to connect system with each other to interact or share data. It is easy to get internet access for all your computers without using a single wire by using these wireless routers. You can be free from wiring problems. These types of wire-free routers have functioned with the support of radio waves. It uses aerials for transmitting signals. These kinds of routers offer high speed internet connection. These wireless routers are also known as wire-free routers.

What is the advantage of routers?

Modem is a main hardware used for getting internet access. But most of the users prefer routers in stead of modem. It has featured with an added advantage of getting access by using a single modem to all the computers. When you use modem, you have to use one modem for every single system. Suppose you have 7 systems, then you have to get 7 modems to get internet access. But when you choose router, there is no need to buy each one for all the systems in your local network.

Cable vs DSL: How To Know What’s Better For You

By: Michael Cohen

With the fast pace development of the internet technology today, it’s very possible to connect to the world and get information in just a matter of seconds. People who frequently go online have a choice between close broadband rivals cable operators or DSL (digital subscriber line) service for instant access to the internet. The battle continues between cable and DSL companies who promise to provide customers with the best service for high-speed data transmission.

Broadband technologies started to develop in the early part of 2000. In the U.S. alone, broadband internet usage either through cable modem or DSL connections soared from only six percent in June 2000 to 30 percent in 2003, according to a study.

Cable

Cable operators, through their cable modem service, provide broadband using the same coaxial cables that transmit pictures and sound to your television set. Most cable modems are external devices that have two connections – one to the cable wall outlet and the other one to a computer. With this type of modem, a user can both watch cable TV and use his computer at the same time. Instant internet access similar to DSL can be achieved just by turning on the PC.

With a residential cable internet connection, a user can have download speeds between four to six Mbps or roughly 70 times faster than a dialup connection. Cable consumers can even opt to bundle their internet access with digital cable TV and digital phone service to avail of discounts.

Cable companies especially in the urban centers felt threatened with the entry of DSL and immediately took action spending billions of dollars for upgrades. Many of them have boosted their download speeds in hopes of competing with cheaper DSL offers.

DSL

DSL is a telecommunications service that allows an ordinary telephone line to be used as a high-speed conduit for data, voice and video. It boasts of broadband speeds over ordinary telephone lines and is considered one of the fastest growing high-speed access technologies best for both business and personal use. Among the telecommunication technologies available today, DSL is the most powerful and flexible solution for high-speed internet access and information transfer.

A typical DSL connection enables users to receive data at a maximum of 1.5 Mbps and send data at 256 Kbps. The nearer your location to the provider’s central office, the faster the speed you’ll get. And what’s best about this is that with DSL, connectivity is always guaranteed. In other words, a user can be sure to go online instantly as no dial up connection is needed. In some cases, users can even use the same line for voice and data traffic.

Apart from its high speed connectivity, DSL is very cost effective in that a user needs only little new equipment and no new telephone lines. It is easy to use and requires no further training.

DSL technologies come in various forms depending on a user’s location and bandwidth needs. These are the IDSL (ISDN digital subscriber line), ADSL (Assymetric DSL), VDSL (Very High Speed DSL), RADSL (Rate Adaptive DSL) and HDSL/SDSL (High Data Rate DSL/Symmetric DSL).

So you decide which of these two broadband technologies suits your needs. If you only need internet access without getting a new telephone line, then the DSL may be best. However, if you want to subscribe to a cable TV and have fast internet access at the same time, then the cable modem will suit you best.

Everything There Is To Know About Broadband Internet

By: Dalvin Rumsey

In order to fully benefit from a broadband internet connection, the first and most important thing one will need is a high-speed modem. Starting from the early 2000’s, the internet has become more and more popular among people from various countries. No matter the field we are working in, the internet is a very useful tool, as well as a means of relaxation in our spare time. There are three types of broadband internet connections: DSL, cable and satellite. All three of them offer a high speed in accessing the information we are interested in.

Many people having dial up internet connections may not get the whole picture of having high-speed internet access. Once they have the chance of comparing their home internet service to a broadband internet connection on their office computer, they will surely see the huge difference.

The most popular type of broadband internet connection is the Digital Subscriber Line, or for short, the DSL connection. Large amounts of data can this way be easily and quickly transmitted everywhere in the world. There are many rural areas that have cable which offers broadband connections. The single drawback of a DSL connection is the fact that all the customers share a certain amount of bandwidth. The broadband internet connection can therefore get quite slow at times. Cable companies try to avoid this by adding additional connections as the number of users increases.

Let us take a look at the benefits broadband internet has brought over dial up internet access. First of all, broadband is way faster. A customer can therefore instantly access information on the Internet. There is no need for a phone line, so the internet connection doesn’t need to be terminated in order to make a phone call. This will ensure the fact that one will never get disconnected, as it used to happen to dial-up users. The problems related to connecting to the internet during peak hours will also be solved.

The broadband connection can be a very pleasant means of spending your free time, as there are millions of movies and videos one can watch over the internet. The user has the choice of either downloading them into his own computer or directly watch the movies online. The buffering is very good, so there will not be any chance of not having a good time watching videos or listening to music over the internet.

The best option for getting a broadband internet connection is to get a package deal on cable services and broadband internet. You will save money over having them at two separate providers. Just go out and experience broadband internet and you will not be able to live without it!
