- Latency: Time delay in data packets from A to B
- Spectrum: invisible radio frequencies on which wireless signal travels
- Band: range of radio frequency
- Standalone: independent architecture for given G
- Fiberisation: radio towers connected via optical fiber

Working, in 3 bands:
- Low Band: wide coverage but lower speed (100Mbps), can penetrate through wall/window, long range communication
- Mid Band: Higher speed, limited coverage
- High Band: Highest speed, no penetration through window/wall, short range communication (5/9)
- Low Band: wide coverage but lower speed (100Mbps), can penetrate through wall/window, long range communication
- Mid Band: Higher speed, limited coverage
- High Band: Highest speed, no penetration through window/wall, short range communication (5/9)
