More spectrum issues?
Does PTA fu*king realize this sh*t after they allocate the spectrum? Bloody idiots. They screwed up Zong's 3G initially as well with the exact spectrum that is used on DECT 6 (1.9GHz) phones.
The uplink frequency of 850 MHz does somewhat clash with 900 MHz GSM.
The cell towers for most networks have to have receive and transmit filters to reduce interference between both frequencies.
