Did you know that by entering a shortcode on most Android phones, you can access a hidden menu which gives you a lot of information about the network and device, including radio frequency used (ARFCN) and signal performance?
In a previous post I presented how to calculate the maximum throughput of LTE, and this was focusing on LTE FDD (Frequency Division Duplex), where an equal bandwidth of spectrum is allocated for both the Downlink and the Uplink. As a reader asked, in this post we do the same for LTE TDD (Time Division Duplex) a.k.a TD-LTE.
Recently I have been trying to find studies on how people consume data on Internet during a typical day, in order to find out what is the proportion of data volume actually done in conditions of mobility and the rest which done in fixed locations. Although I think it could be a very interesting subject for a thesis or a research paper, I could not find anything. So I tried to come up my own evaluation.
Snapdragon just announced the X16 LTE Modem that can achieve 1 Gbps throughput thanks to higher order modulation (256 QAM), 4×4 MIMO and 4x Carrier Aggregation of 20 MHz. But how can we calculate the maximum theorical peak LTE throughput depending on those parameters?
