What will 5G technology bring to the table? Increase speed, more spectrum band use, CBRS at 3.55 GHz, C-Band (3.7 to 4.2), 6 GHz for unlicensed 5G (licensed assisted access), and millimeter wave (60 GHz).
With 5G, comes new use cases. New hardware will be required and we’ll hear terms like 5G-NR which means new radio. Other terms you should know is G-Node-B (the name of the AP in 5G) and Node-B, from 4G.
Do Wi-Fi Engineers care about 5G? Yes! It’s more accessible than the past and is driven by the use case to meet business needs. There’s a lower barrier to entry, no longer high and it becomes another tool in the tool bag.
Complementary to Wi-Fi. Private 4G & 5G can handle devices that need an express lane handled by the corporation. The traffic can be scheduled in a granular fashion.
Design is still going to be critical but you aren’t designing the network the same way. You need a different mindset. Handover is treated differently and there isn’t co-channel interference because of increased coordination. There is a minimum amount of signal separation between access points on the same channels.
This is a great episode to listen to if you want to get a start with 5G before diving into the technical details.
