Abstract
Some embodiments of an emergency radio frequency (RF) repeater system includes a remotely adjustable conveyance characteristic between multiple antenna nodes and a repeater. Optionally, the characteristic may be adjusted independently for each node. Optionally, adjusting the conveyance characteristic after installation of system hardware simplifies system installation and/or facilitates precise balancing of conveyance and/or improves system performance. A conductive riser cable optionally carries multiple channels, for example including an RF signal and/or a communication/control signal and/or data and/or electrical power between system components. For example, the riser may carry a command to the adjustable coupler, to adjust a coupling factor between an antenna node and the riser. Optionally the riser includes a coaxial cable and/or is fire resistant. Optionally, portable transmitter location is estimated from received signal characteristics measured at nodes at different locations. Optionally, the data (for example measured signal propagation) is used to monitor system health.
