4G Zones & NetworksTM
4G (4th Generation) wireless networking for computers and hand-held device technologies is be a significant advancement in the United States.   We will be able to download movies and software 10 times faster than our 3G (3rd Generation) wireless devices allowed, and the devices themselves should be capable of offering great multitasking capabilities.
At this time the largest nationwide 4G wireless network coverage available in the United States is T-Mobile.  Although spotty in some cities such as my area (Sioux Falls, SD), this network offers the broadest 4G coverage, which is why AT&T tried to buy them.
The best part about T-Mobile is that they are currently pioneering pay-as-you-go plans for android smart phones.  While there are many offers from no-contract phone provides, few of these allow an android based device a pay-as-you-go opportunity on a 4G network.
That said, Verizon has a great reach with its fast 4G LTE system.  The 4G LTE solution is currently the fastest and most advanced available in the U.S.  And Verizon has been available in smaller cities and metropolitan areas such as Sioux Falls, SD, since the begining of 2011.
Sprint is working to build the the first US 4G capable network, but it is making alarming slow progress at rolling out the 4G platform to the rest of the country.
AT&T offers some 4G network coverage areas, but the area is small and insignificant.  To top that off, AT&T reportedly offers the most unreliable service with the most dropped calls, afterall.  At one time AT&T mobile coverage wasn't even available in this state.  iPhones were absolutely useless here.
Other countries (i.e.: Japan) are already utilizing 4G wireless networks and computing devices, so the USA is significantly lagging behind in this technology. However, these 4G wireless networks and computing devices are coming to us all.   More remote coverage will be the hardest to implement, and will therefore be the last.
The good news is that some smaller wireless internet provider companies seem to be much more serious about propogating the 4G technology within their own local service areas.  An example of this would be BridgeMaxx, which is claiming to offer 4G wireless internet access right now, even in a remote area such as Sioux Falls, South Dakota.  Even Redwood Wireless has stepped up and is providing local 4G wireless internet accress.
It will be important to have 4G capable wireless computing and networking devices in order to take advantage of this new technology that is coming.  In fact, because the US networks are still so poor and lagging so far behind the current Asian markets, that we are astonished how far back we lag in the implementation of this technology.
Even if we knew about them, we couldn't even test these 4G networks without the right equipment and the appropriate contract.  However, any 4G device manufacturer or wireless provider can send the editor a sample unit at:
