Re: What about 2G, 3G, 4G?
"If I remember my el reg articles correctly 4G was a term coined by the marketing rather than the engineering department. 5G maybe the same. I take your point about network coverage though. Will handsets have to support three generations of wireless standards and their various flavours around the world? Could end up pushing the price of phones up."
They also have to support wide range of frequencies. My newest mobile phone supports.
LTE (4G) 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 12(700), 17(700), 20(800), 28(700), 38(2600), 40(2300)
What is missing is LTE 450 that is being tested and developed. It is going to be used in the Nordic countries (Iceland, Norway, Denmark, Sweden, Finland + Greenland and Faroe Islands).
All this spectrum is big drain on the battery due to scanning. It also has NFC (13.56Mhz). Bluetooth (2.4Ghz) and WLAN 2.4Ghz and 5Ghz. This is a lot of antennas (some might be shared) for one phone and battery drain if everything is turned on. I try to keep most of this turned off.
I got Sony Xperia Z5.
