Thanks. Looks like a great community. I spend most of my time in the Alexandria, VA, DC, Rockville, MD region. I think tri-band phones are currently experiencing the eCSFB issue and falling back to 3G around here. Is that your understanding?
I'm gradually finding all the good info here in s4gru.com. So far, I see the legacy and NV vendor in this area is Alcatel-Lucent; NV sites are roughly 75% accepted and LTE sites are something like 35% accepted. I don't understand that last metric since NV/Spark will provide LTE on all three bands (25, 26 and 41). Does that mean towers get accepted for LTE first and then gradually get the full Spark/NV upgrade?
