Do you know if the sprint network vision is supposed to have fiber optic lines, or is it only some areas. I live in NYC and the spark network is almost complete, but I think the only band's that has optic cables are bade 41,speedtest's show the downloads are consistent speeds acrosd the graph, band 26 also... Band 45 seems about up 1meg & down 1meg with slow movements to it's top speed. It's antennas strange, it seemd as if network vision 1.0 use copper t1 that would explain allot I guess. reason for its slow start. The other bands start really fast then slowed down to 50/60 MBS speed, the same with band 26. I've been googling for his trying to get an answere. But I just found out more confusing into about Sprint & some other commodity companies has a couple of under sea ootic connections, international waters optic connections for their other long distance industry department. Would they be able to use this to their advantage & connect Sprint wireless to it's nationwide optic network or are they only upgrading done towers to use oc's? I thought the whole NV network would be updated to the latest that wirekess networks has to offer...I can tell that on humid days & rainy days you can see a major show down in the network, from what I've read it's because its a microwave antennas weakness (humidity & rain) so I'd NYC a fiber optic connected city or copper? I would like to know since it's since this will help me decide to either move to T-Mobile or at&t. I'm hoping it's modernized enough that they've gone the optic cable route. Please someone that know's give me something, thanks everyone.
