- 3GPP. This stands for 3rd Generation Partnership Project. Despite the three in the name, this is a group of seven standards-setting organizations that organize the rollout of 5G standards and definitions. It’s not really 5G until 3GPP says it’s 5G.
- mmWave/millimeter waves. High-frequency waves in the millimeter band between microwave and infrared that are used to deliver faster, high-capacity data. Be warned: Much like microwaves, they’re susceptible to being blocked by buildings.
- MIMO (Multiple-Input Multiple Output). It’s a good old-fashioned technology that lets you send and receive more than one data signal on the same channel by using more than one antenna. It can help increase capacity.
- Enhanced small cells. Low-powered cellular radio access nodes that serve fewer users than other nodes over a smaller geographic area. They operate in licensed and unlicensed spectrums from 10 meters up to a few kilometers. 5G needs more antennas, and small cells are one way to achieve that.
- 5G NR. The NR stands for “New Radio.” This 3GPP standard combines millimeter wave, enhanced small cells, MIMO beamforming and a few other things. It’s the 5G standard the 3GPP has blessed, and companies who have started out developing others like 5G TF, or 5G SIG, will transition to 5G NR.
- 5G does not come without challenges, but that possible user data rate of 1 Gbps sure does make it worth the effort.
