Bigger is better, right?! Only this time it is instead of 1 big tower doing the task of serving N number of phones, it is going to be multiple smaller towers that are going to take on the task of serving smaller chunks of the population. The way it works is instead of having long range transmission with low frequency plagued by latency, the 5G technology solves the latency (slow speed) issue by breaking the data in small chunks and transmitting through high frequency band width and placing the server or the computational facility close to the device that works on the processed information. The demands the 5g servers will have are totally separate from what the 4G servers have had to do. The computational process is a different set of challenge as well, in the 4G world they computational work was done in a hand full of places in the whole of North America. However their are CDN (content delivery networks) that help disperse this results with speed, however those units were just aiding in the transfer process and not the computation process where the real processing and mathematical calculations were done. It was a good system sufficient enough to get the job done and that is why companies like Akamai were such good ideas in the past decades. However the new technology requires not only speed in delivery but also speed in computation. The best analogy would be to compare the CDN’s to the muscle and the main server centers as the brain. With a stronger muscle you can do the heavy lifting faster when lifting something but the signal to lift that item has to be given by the brain. Instead of having 1 big elephant lift a huge log like we are doing with 4G, we are dividing up the log into smaller chunks and having multiple donkeys carry it to the destination with the 5G. With the later approach you can deliver logs of different kind faster since that is the type of data that is required in the modern 5G world.
For instance, lets take an autonomous car and the car is going down the city streets, with the 4G world if a GPS senses an obstacle on the middle of the road and a car is approaching fast around the corner, the car must have the information about the obstacle ahead of time to get ready to stop or slow down. With the old model where the server is at one of the country and the car is driving at another, the latency or the speed with which that particular car can get that notification could be 5 sec slower then having a computational facility near by with the way it is proposed in the 5G world. 5G is going to a game changer in a lot of ways on how we live out lives for sure.
