Ok, update. Heard a few things for us Greenville folks... here's what I learned!
First, the "go ahead" will be given by the end of February for 4G to be flipped on in Greenville. There are towers by ECU campus and the hospital all ready to go, and they are all set to flip the switch - antennas are installed and have been tested. The guys are getting 43 mbps download speeds right on ECU campus, but they realize the speeds will decrease as more people jump onto the network. That's good news, though! Also, they seem to be testing the towers early in the morning, between 2 and 6 am.
Potentially bad news is that there have been some issue with the towers by Pitt County Memorial Hospital (PCMH) with the fiber optics lines going to the towers. They suspect maybe some water leaked into the lines or something like that, but they're not sure and need to look into it. It's giving them some 3G/4G issues in that area.
Further, the 4G coverage in Greenville will be pretty wide-reaching, actually. It'll blanket basically the entire town, and down past Winterville all the way to the edges of Ayden (that's pretty nice). Washington, NC will also have 4G around the same time, it'll be included in what they call the "expansion" part of the network. Winterville will also be part of the "expansion." The expansion just means "extended coverage areas" which will get 4G but the signal will be weaker. Right now, they're saying 10-15 mbps in these expansion zones, and 20-40 in the main zones (Greenville). The one bad thing to note about Winterville is that it'll be almost right in the middle of a few towers' 4G signals, so some people will get poor building penetration the network guys said. However, walking outside you should get really fast speeds again, it's just that indoor coverage may be a bit poor for some people.
Finally, the network team knows about the problems on ECU's campus and in other parts of town where 3G service is poor. This is attributed to too few towers, too little backhaul (fiber optics) running to existing towers, and too many people/devices connecting to the 3G towers. This will be remedied some when 4G is lit up in less than 2 weeks, but the problem will probably still be there by and large. They have already laid the steel for additional towers (yes, we'll be getting additional towers in Greenville!!!) and they'll be built up within the next year, so we'll have better 3G coverage relatively soon. Add in the fact that many people will jump over to the 4G network when it turns on and 3G service should mildly improve soon and majorly improve in the near future.
