Expanding Rural Cellular Networks with Virtual Coverage
summary
A prototype implements virtual coverage by modifying a GSM base station, patching Motorola phones and adding a small backward-compatible radio so handsets can send a wakeup burst or use a wake-up radio; the base station power amplifier is switched off when idle. Measurements show up to 84% power savings versus always-on, simulated savings of 21–34% at night and 7–21% daytime, and capex drops from ~$15k to about $4k for low-utilization rural installs; deployed nodes in Papua are operational.
