What is 5G? �

  • 5G (5th generation wireless systems) is the next major phase of mobile telecommunications standards.
  • still under development
  • The initial 5G New Radio (NR) specification was completed in June 2018 and published in the 3GPP Release 15 specification.

What’s driving 5G?�

  • Internet of Things (IoT)

To achieve these objectives, 5G will provide :

  1. extreme broadband speed
  2. ultra low latency
  3. ultra reliable web connectivity. �

Millimeter Wave�

  • is a band of radio frequencies that is well suited for 5G networks.
  • millimeter wave technology allows transmission on frequencies between 30 GHz and 300 GHz.

9 of 22

Vehicular ad-hoc networks (VANET) :

9

    • Vehicular ad-hoc networks (VANETs) are created by applying the principles of mobile ad hoc networks (MANETs) – the spontaneous creation of a wireless network for vehicle-to-vehicle (V2V) data exchange – to the domain of vehicles.

Advantages and disadvantages : �

Advantages of V2V:

  • 1-Improved road safety
  • 2-Reduced traffic congestions
  • 3-Helps in streamlining of the flow of vehicles on road

​

disadvantages of V2V:

  • The threat of hacking

                  • We used the code to simulate the technology’s work in normal street contains 4 lanes , with among cars and different speed and location we were searching for car number 41 and the communications that it get from other cars.

MATLAB code:

12

  • clc;clear;close all
  • trafficdensity=[100 150 200 250 300 350 400 450 500];
  • for cars=100:50:500
  • ycoord1=transpose(randperm(5000,cars));
  • target=41;

13 of 22

MATLAB code (Cont.)

13

  • ycoord1=sort(ycoord1,1);
  • positions=zeros(5000,4);
  • speed=zeros(5000,4);
  • speed(index,1)=(31-22).*rand(1,1) + 22;
  • if pdist(X,'euclidean')< 40 %communication range has to be changed here to get outputs for a different range
