My guess (hope?) is that they're planning to roll out a WiMax repeater in Q1 2011. I've seen other people quoting pricing of $5 /mo to add the 3G repeaters to their homes. I can't attest to the accuracy or veracity of that information. To my understanding, what I'm looking for here is a Sprint 4G WiMax repeater. So far as I know anything not authorized and installed by Sprint or Clearwire is most likely illegal and/or non functional.
Basically it acts like a mini cell tower in your house providing great coverage for about 50'. It uses your existing high speed internet connection as backhaul to the Sprint phone network.
Not only are there several repeaters out there, most of them are not made or distributed by sprint or other cell carriers.That does not make them illegal or ineffective. I do know that you just have to make sure whatever repeater you buy matches up with the frequency of your carrier. The bad thing about these types of repeaters is the fact that they are usually expensive and they actually repeat signal. So, if you don't have any signal where you are, a repeater will not work for your application. The repeaters that Sprint and other carriers use piggybacks off of a wifi signal and require no cell tower to be in range.
Well then it's worthless to me, since: 1) My voice reception is already fine. 2) I have no wired internet access, that's why I need internet from my phone! Honestly, this seems like a no-brainer, Denver already has some 4G coverage. Coverage could be expanded more rapidly (and with more customer satisfaction) if 4G repeaters were more readily available.
I haven't found many 4G repeaters that work on Sprint frequencies. Plenty of EVDO, but only one 4G. I realize this discussion was started regarding voice connectivity, but this topic seems to be the most appropriate place to ask. I'm concerned with 4G reception at home and work, since there's no concrete info about which areas of Denver will receive 4G coverage at which times. A low range base station that runs off a land line would be largely redundant for 4G, since WiFi would offer a better alternative for people with such land lines anyway.
The new Airave that wengla02 linked to, http://www.airvana.com/products/cdma-femtocell/, was available for a short time. It appears that they were having problems with it. We were told to go back to the original Airave for the time being.
