A mobile broadband like cable broadband is only as good as saturation capabilities allow. Look at what happened in NY with AT&Ts network had so many iPhone users that AT&T had to stop offering new mobile broadband coverage.
With the anticipation that Apple's newest iPhone which will be released within the upcoming months will support CDMA (Verizon's protocol) there will likely be an increase of users thus adding to network congestion, slower speeds, etc... My assumption is that Verizon while implementing their new 4g network has taken this into consideration and "beefed up" the carrier side. Ancillary to that, new data plans are no longer "unlimited" as they once were which means less network requests which levels out to mean less congestion which equals faster speeds. (Thant’s allot of whiches.. I know..… )
Users that do not have 4g enabled equipment will not notice faster speeds however the 4g side of the network will seem faster to 3g users as more 4g users transition over. This should provide faster upload and download speeds all the way around and will most likely place AT&T in an awkward position of having to do something to its aging network to compete.
LTE is a topology for a 4th generation wireless broadband that was developed by 3gpp which is a large group of industry experts.
The engineers named it Long Term Evolution because it represents the next jump in wireless broadband. (Hence it has evolved over a long period of time since the 2g days).
LTE provides faster data rates than previous topologies being that it has the ability (not saying it will actually do this) but the potential and support is there for 4g to facilitate speeds of 100 megabytes per second down and 30 up. Future builds could actually push it into the capabilities of say your "Wireless N" home routers which are capable of moving 300 mbps.
The best thing about LTE is that the top layer is TCP/IP based (the protocol that your computer uses to talk over the web) meaning that with advanced quality of service builds different layers will accommodate simultaneous voice, video and text traffic without one impeding the performance of the other. (faster all the way around...)
The next 4g release will use a technology called MIMO or Multiple In/Output antenna technology which is the same thing in ..... yes.. the majority of your wireless routers at home or a standard called 802.11 N (There goes that Wireless N again).
This means a much improved coverage area in high-demand and highly populated areas, which means.. a better wireless experience.. Now remember, 4g is not at MIMO just yet, but with the potential there and after initial implementations and a 12-24 month equipment cycle of phones, I expect that within 56 months we will see MIMO as the forward 4g standard that essentially will mean your phone's internet could be as fast as your home internet (a good home internet such as regular roadrunner or turbo roadrunner)...
SO the super speeds are a ways off, but 4g will accommodate what we all want in the future which is fast, efficient mobile broadband.
