Why do you need more? Well, when it comes to fixed wireless connections it's more like let's move forward before it's too late. As more users come onto the 4G connection, the network fills up. Soon there won't be enough capacity for everyone's devices. This is especially true with the coming age of smart homes and smart cars. It's no longer just your phone that is tied to the intangible 4G waves. Let's take a closer look at the attributes of 5G.
Millimeter Waves:
The devices you use are on specific frequencies on the radio frequency spectrum. Technology like your phone, a smart watch, or a smart car typically fall under 6GHz. As these frequencies get more and more crowded, experts are looking to use the millimeter wave real estate to add more devices. The more crowded the frequencies are, the more often we will see slow service and lost connections.  
Low powered, mini base stations called MicroPoPs will be dispersed periodically in areas where 5G is available. This allows for the waves to bounce around buildings and trees, meaning you do not lose your connection based on your mobility.
Massive MIMO:
MIMO (multiple input, multiple output) allow there to be almost 8 times as many ports to handle fixed wireless traffic. However, with so many ports communicating, there is likely to be a lot of traffic on the millimeter waves.
Therefore, 5G requires beamforming. This technology sends a focused stream of data to a specific user. Think of it as a stoplight, orchestrating incoming and outgoing data.
Full Duplex:
Full Duplex allows for data to be transmitted and received simultaneously. It allows for noise on the same millimeter waves to be rerouted via silicon transistors (high-speed switches) that can momentarily reroute the data to increase efficiency.   < Back
