Terms on this page

3GPP release: The version of the mobile standards a modem implements. Later releases add features.
5G SA and NSA: Standalone 5G uses a 5G core network; non-standalone 5G is anchored on 4G.
IP rating: Protection against dust and water. IP30 and IPX0 equipment is for indoor or enclosed installation.
WAVE Portal: Nextivity's cloud platform for monitoring and configuring CEL-FI systems.
Echo cancellation: Lets a repeater run high gain without feeding back between its donor and server antennas.
DSS: Dynamic spectrum sharing: 4G and 5G sharing the same frequency band.
FDD and TDD: Two ways of separating upload and download: by frequency (FDD) or by time (TDD).
