You Had Me At EVDO

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.

By the way, you can purchase the same Amp’d Mobile Phones through Dealking.com at the same or cheaper prices, but also receive $25 cash back. Check it out at dealking.com.

Discover Sprint EVDO and Verizon EVDO Services

Written by oneself on 6:52 AM

If you are the type of person who starts to shake and get a cold sweat whenever you are not able to get an Internet connection with your laptop, there is hope for you. One of the hottest technologies available today, which is gaining tremendous momentum every day, is the EVDO data services, where the leaders are Sprint EVDO and Verizon EVDO.

What is EVDO? It is a card that plugs into your laptop computer, either PCMCIA or USB, that allows you to connect to the Internet via the provider's network. Some of the newer high-end laptops are coming with EVDO service already built in, although this is almost a waste if you want Sprint EVDO and Verizon EVDO is built in, or vice versa.

No longer do you need to be at a Starbucks or wireless coffee shop or hotel to be able to connect to the Internet. EVDO stands for Evolution Data Only/Evolution Data Optimized, and you will frequently see it abbreviated as EVDO, EV-DO, EvDO, 1xEV-DO or 1xEvDO. EVDO provides fast wireless broadband (also known as "3G") Internet connectivity service directly to your laptop. You take the internet with you and surf the web in your car, on the train, in the airport, at a convention, on the road in your RV.

The speed of the initial rollout of EVDO (1xEVDO) is available in most metropolitan areas throughout the United States. The newer release of EVDO known as "Rev 0" is available in about 200 metro cities through the US, and both Sprint and Verizon are rolling out "Rev A" EVDO to upgrade the current implementation, as well as starting to cover more areas continually.

In terms of speed and performance, EVDO is superb. The Rev-A EVDO service delivers about 600-800k downloads and 300-400k uploads with a good signal from the cellular carrier. But even the older "Rev 0" speeds give you tremendous flexibility, although speeds are only about 2-3 times faster than a dialup connection. But even so, the flexibility of being able to get online virtually anywhere makes this a tremendous boon to those who don't want to be tethered to a wireless coffee shop or hotel lobby.

Cingular also offers something similar to EVDO on their networks, although at the time of this writing, it is typically not nearly as fast and does not have nearly the wide coverage throughout the US that the Sprint and Verizon EVDO networks do.

Sprint and Verizon are constantly leap-frogging each other in terms of which one covers more area and which one is faster.

One thing to watch for is the cost, which is a function of how much you download over the course of the month. Both Sprint EVDO and Verizon EVDO have plans that allow 20mb per month, 50mb per month, and various levels, as well as an "unlimited" plan. With the size of most websites these days, you can burn through that download limit in a day or two, so the unlimited plan provides your best value. However, be aware that with Verizon, unlimited does not mean unlimited. If you use Verizon EVDO "too much", they will shut off your EVDO service for the remainder of the month. Verizon has yet to actually state how much is "too much", but it is definitely not "unlimited" according to the dictionary definition of the word. By contrast, the Sprint EVDO unlimited plan, at least for now, is truly unlimited.
