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.
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?
I often had to explain in simple terms the concepts of Busy Hour and Busy Day to non-technical colleagues while working on network capacity planning. Eventually I decided to come up with a simple illustration that helped me a lot to clarify the concept. This is what I am sharing today.
There is a race between equipment manufacturers, chipset manufacturers, carriers and standardization bodies to take the lead on defining what 5G will actually be. One of the hot topics is the choice of the most appropriate waveform and mutliple access method to meet the requirements of 5G.
