- Where EVDO isn't available, 2G/1x data capability is available everywhere you have have cellphone voice service
- Allows the user to be connected wherever they are are not only for email, but for downloads, large files, photos, spreadsheets, etc.
- Advantages over WiFi: - Always on with seamless roaming! - Signal can travel on same cell sites as cell phones - You are your OWN hotspot - you're not relying on someone else's internet connection - No 300-ft range from the cell tower or "hotspot" - Customers can access their corporate VPN (virtual private network) anywhere they can get a cellular signal via a secure, encrypted signal - Can download and run video clips in real time - Can provide service to customers outside of cable-modem or DSL areas
- Relatively low cost with high capacity - allows rich web browsing and application usage
- EVDO Rev A provides speeds of 600Kbps-1,400Kbps Download (bursts to 3.1Mbps), 500Kbps-800Kbps Upload (bursts to 1.8Mbps) - comprable to home DSL service.

What is EVDO / Mobile Broadband?
This article contains a plethora of information on EVDO and mobile broadband
(how fast it is, how it works, what types of people use it,
and more) - if you'd like to read just the basics and find out what you need to use mobile broadband, we recommend reading the concise "Mobile Broadband Basics" guide, which covers all the essentials: what you need in order to use mobile broadband, what the service options are, etc.Getting online and being able to connect with friends, family, news, and the office is more important now than ever, but what happens
if you're one of the millions of Americans without access to traditional broadband like cable or DSL, stuck in a hotel without WiFi,
or cruising at 65mph down the highway in your Winnebago? The answer ismobile broadband! Mobile broadband
provides completely wireless internet access. 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... you can even share the connection with multiple computers using a mobile broadband router, just like you could with your broadband connection at home!"Mobile Broadband" is a generic term that describes this type of internet connectivity, but there are a few related terms that will be helpful to understand.
EVDO, or Evolution Data Only/Evolution Data Optimized, is a 3G mobile broadband technology used by Verizon, Sprint, and Alltel that provides
typical download speeds of 600-1400kbps (with bursts up to 3100kbps) - this article focuses mainly on EVDO mobile broadband. HSPA is another 3G technology that is used by AT&T and T-Mobile (click here to read more about HSPA). 4G is the next generation of mobile broadband technology, but it's not as widely available as 3G service yet - Sprint uses a 4G technology called WiMAX that is currently being deployed, and Verizon will be deploying a 4G network using a technology called LTE in late 2010. For more information on 4G, read the What is 4G? article on 4Ginfo.com, our sister site.

From Wikipedia: Evolution-Data Optimized
Enhanced Voice-Data Optimized or Enhanced Voice-Data Only (EV-Do, EV, EVDO, etc.) is a telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access. EV-DO is an evolution of the CDMA2000 (IS-2000) standard, but EV-DO will support high data rates yet can be deployed alongside a wireless carrier's voice services. So EV-DO now (2013) stands for "Evolution-Data Optimized"[1] It uses advanced multiplexing techniques including code division multiple access (CDMA) as well as time division multiplexing (TDM) to maximize throughput. It is a standardized part of the CDMA2000 family of standards and has been adopted by many mobile phone service providers around the world - particularly those previously employing CDMA networks such as 3G. It is also used on the Globalstar satallite phone network.[2]
An EV-DO channel has a bandwidth of 1.25 MHz, the same bandwidth size that IS-95A (IS-95) and IS-2000 (1xRTT) use.[3] The channel structure, on the other hand, is very different. Additionally, the back-end network is entirely packet-based, and thus is not constrained by the restrictions typically present on a circuit switched network. ..." ... continued ... (see below).
