MESH Networks, Mesh Networking (6G WBAN)

A mesh network is a local area network topology in which the infrastructure nodes connect directly, dynamically and non-hierarchically to as many other nodes as possible and cooperate with one another.

Meshing, or dividing a complex object or scene into smaller elements or cells, is fundamental in engineering simulations. Meshes allow computers to accurately simulate the behavior of objects or systems under different conditions, aiding engineers in making informed decisions.

5G Tower Locations:
5G promises an extremely interconnected world where everything from smartwatches, vehicles, houses, and farms utilize the ultrafast speeds and low delays it offers. To accomplish this, and to do it well—with as little coverage gaps as possible—it’s required to have a huge number of 5G towers, particularly in areas that demand lots of traffic like big cities, large events, and business districts.

Fortunately, since 5G cell towers are so small, they can be positioned in ordinary places like on light poles, the tops of buildings, and even streetlights. This translates into less traditional-looking towers, but also potentially more eyesores nearly everywhere you look.

5G small cells are fairly simple in design and can be installed in less than a few hours, sometimes even faster, like with Ericsson's 15-minute streetlight solution, Street Radio 4402. This is very much unlike the beefier 4G towers that take much longer to install and get up and running.

Of course, small cells also require a power source and backhaul to connect it to the carrier's 5G network, and eventually the internet. A carrier might choose a wired fiber connection or wireless microwave for that connection.

Small cell is an umbrella term; there are three subtypes, each with their own purposes due to their different sizes, coverage areas, and power requirements:

Microcells and picocells are good for outdoor use because they have a range of up to 200–2000 meters (just over a mile), respectively.
Femtocells are preferred indoors due to a coverage radius of less than 10 meters (32 feet).
