4g has not yet come to my area, but I do have extensive experience with networking 3G devices wireless devices together. And my same plan would work equally well with Verizon 4G, aka LTE.
My set up is follows, as my wife and I have a 1 desktop computer each, and also one wirelessly capable laptops each. With the 3G Verizon MIFI 2200, I can network both desktops together using Windows ICS, a crossover cable between both desktop's enternet ports, and my MIFI 2200 (or any other 3G Versizon modem for that matter ) connected to the USB port of the host computer on the ICS network. AND I GET EXCELLENT ROCK STEADY results. And anyone who has had problems with ICS is probably not setting up a Static DNS address for the client computer of the ICS network. Of course, in that mode, the MIFI 2200 does nothing to get wireless access
for my laptops.
But if I want to network in all 4 computers (2 desktops and 2 laptops ) again my MIFI 2200 modem is a two mode device, as its becomes a two trick pony. Because if I plug the MIFI 2200 into its AC battery charger to keep it charged or just leave it free standing, it suddenly becomes a combination wireless 3G signal receiver/ wireless G modem able to to power up to five wireless devices using any OS. Which feeds wireless signal to my two laptops no problem, but does nothing to feed internet to my two desktops. Until I bought two cheap $10.00 USB devices to make my desktop computers capable of receiving a wireless signal. And that works for me too. Especially on patch Tuesday when I have to do the windows updates on all 4 Computers. I should also note if I want to take the show on the road, I grab one laptop and my MIFI 2200 modem and leave. Of course the other 3 computers at home lose their internet, but if my wife is gone too, there is no one left in the house to use the other 3 computers.
Two other things to say, the 4G Verizon equivalent to my MIFI 2200 3G modem is the 4510L. The second thing to say, is that you could do similar 3G or 4G things with a router, but not just any router, it has to be one specifically designed for 3G or 4G data signals. And while regular DSL or cable modems routers are fairly cheap, 3G and 4G routers, cost about 3 times more than DSL or cable routers cousins.
As for the 5 and 10 GB data cap for month, I agree it really sucks and is a rip off, but a lot of folks like me in rural areas, have no other hardwired broadband internet options. Its either dial up, or 3G or 4G data broadband. Other than even more expensive and slower satellite. And satellite is the sometimes the only remaining broadband option for people in rural areas that can't get any cell phone access at their house either.
