Antenna Factor and Gain Calculations

Antenna Factor and Gain metrics provide crucial insights into antenna performance, allowing engineers to calculate signal strength relationships and directional effectiveness. These measurements help optimize RF systems by comparing actual antenna behavior to theoretical isotropic radiators using standardized 50-ohm configurations.

GR-3175, Generic Requirements for Intrabuilding Coaxial Cable, is a new Generic Requirements document (GR). It sets forth the Telcordia view of generic requirements applicable to intrabuilding-, interconnection-, and premises-type coaxial cables placed between telecom service demarcation points on or inside a building, to telecommunications equipment that may include residential gateways and wireless units.

In normal commercial practices, these products may be called intrabuilding cables or wires, customer-premises cables, and inside wires, among other terms. This GR uses the designation “intrabuilding coaxial cables” to cover coaxial cables that interconnect telecommunications equipment within customer premises, Central Offices (COs), buildings, and structures. These cables are typically used in relatively short runs of a few hundred feet, but they may be longer in larger complexes or tall multi-story buildings.”
