avb Posted April 28, 2012 Share Posted April 28, 2012 With backhaul upgrades being a major component of Network Vision, I want to ask a few questions. 1. Prior to the upgrades Sprint is using T1/bundled T1. T1 can transmit 1.5Mb/s, so how many T1 lines does a typical tower have? If a tower has 10 T1's, that's about 15Mb/s. It doesn't take that many EVDO users to use up that capacity since EVDO rev A can transmit 3.1Mb/s. 2. With Network Vision switching to fiber, microwave, or aav for backhaul, how much of an improvement is Sprint expecting to implement? With the bundled T1 example above, an improvement 10 times that amount would be 150Mb/s. 3. Will only the new LTE phones see the enhanced backhaul? I'm not clear on eHRPD/EVDO, but it seems like the new LTE phones will use eHRPD when not in a 4g LTE area. Will that be separate from the existing EVDO network? It seems like all of Verizon's 4g outages are always blames on their eHRPD network. 4. What type of backhaul is/was Clear using for WiMAX? I'm in Houston, so I'm hoping to see backhaul relieve the 3G issues sooner rather than later. Quote Link to comment Share on other sites More sharing options...
