Terms on this page

3GPP release: The version of the mobile standards a modem implements. Later releases add features.
SFP: A slot for a plug-in fibre or copper module, often used for fibre uplinks between cabinets.
PoE and PoE+: Power over Ethernet carries power and data on one cable. PoE+ (802.3at) supplies up to 30 W per port.
IP rating: Protection against dust and water. IP30 and IPX0 equipment is for indoor or enclosed installation.
4.3-10 connector: A compact, low-PIM RF connector used on DAS equipment.
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).
