Problem
The first level of development of a wireless modem typically is a software simulation of the physical
layer transmitter and receiver. The air interface is simulated with a channel version that tries to
recreate actual global situationswhichinclude noise,fading,multipath,Dopplerunfoldandpathloss.
Variouscomponentsof the receivermaybe carried out in an ANN that are pointedoutin thispaper.
Atthispoint,MLwill takelocationinANNswhereinthe varietyof nodes,layers,connections,activation
capabilities and again propagation loss capabilities all want to be bendy whilst the network trains.
Duringthispreliminarylevel,the numerousparametersandtraitsof the ANN will want tobe diagnosed

3. Invention
Althoughperformance,cost,andsize are alwaysconsideredwhenimplementingneural networks,they
are extremelyimportantwhenimplementingmachine learningalgorithmsatthe userequipment(UE)
or cell edge. When modeling and prototyping ML on UE, other considerations should also be
considered. Optimize the physical implementation of the project. Early in the design phase,
deploymentcan be software-centric.The onlyway to get the expectedbatterylife throughreal-time
calculations is to switch to a hardware-centric solution. And the expected requirements for artificial
neural networks (ANN) at these stages. It is expectedthat the learning will be carriedout during the
modeling and prototyping stage. For the final product, the end-to-end network is transferred to the
physical device,wherethe weightisstill definedbythe software,butotherattributescanbe captured

➨6G will virtualize additional components,suchasPHY layerand MAC layer.CurrentlyPHY/MAC

4. costs of networking equipment’s.Thismakesmassivelydensedeploymentin6G economically
feasible.
Disadvantages
➨6G uses cell-less architecture and multi-connectivity. Hence seamless mobility and
integration of different kinds of links (THz, VLC, mmwave, sub-6GHz) need perfect
scheduling. In cell-less architecture, UE connects to the RAN and not to a single cell. The
challenge here is to design new network architecture.
➨6G uses THz (Terahertz) frequencies for part of its communications, hence drawbacks of
THz can be considered as drawbacks of 6G wireless technology. The terahertz frequency
refers to the spectrum between 0.1 to 10 THz EM (electromagnetic) wave with wavelength of
30 to 3000 micrometers. Terahertz waves can be widely used in the space communications
particularly suitable for use between the satellite. THz signal is very sensitive to the shadows
which has great impact on coverage. Moreover lower frequency terahertz frequency incurs
larger free space fading. Ultra-large-scale antenna is a major challenge in THz which requires
high bandwidth and massive quantitative high resolution. Processing power is major
challenge in designing low power and low cost 6G devices.
➨6G uses visible light frequencies for part of its communications, hence drawbacks of VLC
can be considered as drawbacks of 6G wireless technology. Visible light uses wavelength
from 390-700 nm.
➨In order to manage large number of terminals and networking equipment’s more efficient
and less energy consuming 6G system is a must. In order to fulfill this, network and terminal
equipment’s circuitry and the communication protocol stack design is a challenge. The energy
harvesting strategies are adopted to handle this requirement.
