#5G supports frequencies up to 100 GHz. Is mobility feasible at when the wavelengths are in the millimeter region?

#5G networks will move towards centralizing the radio function using an eCPRI based fronthaul. The main objective here is to limit the electronics needed at the antenna site. This lowers cost, as air conditioning is not needed at the antenna site.

#5G AN uses LDPC for channel coding on the traffic channel. LDPC corrects channel errors by maintaining parity bits for a selection of the data bits. The figure below shows the relation between the data and parity bits.

Typically, #MIMO is implemented with multiple antennas at the base station and the mobile. #5G systems take the MIMO concept even further by adding a very large number of antennas at the base station. This is referred to as massive MIMO.

#Haskell is a pure functional language. This means functions in Haskell behave closer to mathematical functions. A function operates on the input parameters and returns a result. Functions do not modify state.

Lambda calculus is a model for expressing computation without state. It is an alternative to the conventional state based Turing machine model of computing.
