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 is mobile 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.
What is EVDO? Just the Basics:
How does it work?
EVDO works similarly to the way your cell phone operates in that it relies on signal from a wireless tower rather than a physical connection like a phone line or cable. An EVDO modem (often referred to as an "aircard") receives the signal and allows you to connect to the internet - it's as simple as that! EVDO modems come in several formats: USB dongle, ExpressCard, PCMCIA card, or all-in-one hotspot (like the MiFi) and you can use them either directly in your computer OR in a 3G router.
Of course, like your cell phone, the modem alone doesn't provide internet access - you must subscribe to the service from an EVDO provider. Sprint and Verizon both offer EVDO service for $59.99/mo with a 5GB per month allowance, and both charge overage fees for usage exceeding 5GB (Verizon also offers some alternative plans for the MiFi hotspot). For most people, 5GB is plenty of data for surfing the web, emailing, and the occassional YouTube video. For more information on what you can do with 5GB, read this article.
Who uses EVDO?
There are countless reasons to use EVDO and we have helped customers get set up for a huge variety of applications! Below are just a few common ways people use EVDO:
How fast is EVDO?
How does EVDO compare to other technologies?
The best aspect of EVDO (to most users) is the mobility it offers, but EVDO is also FAST! With a good signal, EVDO Rev A averages about 600-1400Kbps download with upload speeds averaging between 500-800Kbps. Here is how it stacks up to other common internet technologies:
1xRTT (AKA NationalAccess)
1xRTT is a 2G (second generation) technology that has been available a lot longer than EVDO and is available just about anywhere cell phone coverage is for Verizon or Sprint. 1xRTT has a maximum of 144K upload and download, but the typical speeds are 50K - 80K. When EVDO is not available, your EVDO modem or phone will automatically connect to 1XRTT if available. While considerably slower than EVDO, 1xRTT is a huge boon to travelers - if you find yourself in a remote location with no EVDO you'll still be able to remain connected!
Who offers EVDO and what kind of devices are available?
Sprint and Verizon are currently the leading providers for EVDO service in the U.S. There are multiple EVDO cards in PCMCIA, Expresscard, USB and 'portable hotspot' formats available.
ALL of the currently available modems from both Verizon and Sprint are Rev-A capable and most feature external antenna ports where you can add an antenna or amplifier. Most of them are compatible with at least one 3G router. We have performed extensive tests on all of the modems and can confirm that there is no difference in performance between the available form factors; the various form factors simply provide options for different preferences. You can read more about why there is no performance difference between form factors here.
In the early days of EVDO, Mac users were often "left out in the cold" as companies failed to provide support for their computers. Here at EVDOinfo and our sister site, 3Gstore.com, we have been providing tips and support for using EVDO with Mac computers since the beginning - even when Sprint and Verizon said it wouldn't work! Now, most new devices are Mac-compatible right out of the box, but support for Mac users is still weak. We are proud to offer comprehensive support to our Mac-loving customers!

Is there EVDO service at my home/office/destination?
Both Verizon and Sprint offer EVDO in many areas of the USA, Puerto Rico, Canada, and Mexico (note: using EVDO in Canada and Mexico requires specific devices and plans). To check coverage at your location, you can enter your address or zip code on 3Gstore's coverage tool and compare Sprint's and Verizon's coverage.
If EVDO is NOT available in a particular location, 1xRTT (aka "National Access"), may be available. In areas where EVDO is not available, your EVDO-enabled device (including aircards, USB modems, ExpressCards, phones, or embedded devices) will attempt to connect to the 1xRTT network. Generally, if your carrier has cell phone coverage in a particular area, there should be 1xRTT coverage even if EVDO has not yet arrived there.
Another excellent resource is EVDOmaps.com, a free service hosted by the EVDOinfo experts that compiles actual test results from EVDO users around the country. This is NOT a coverage map but a place where users can post actual speed test results and descriptions of their gear, so that others can see what service was like at that moment in time, from that user's location.
