GSM (Global System for Mobile Communications) and its data extension, EDGE (Enhanced Data rates for GSM Evolution), operate in the 900 MHz, 1800 MHz, and 850/1900 MHz bands. Traditional GSM networks require on-site BTS hardware connected via T1/E1 lines to a regional BSC. The paradigm of replaces fixed T1/E1 links with IP-based transport (fiber, satellite, or LTE backhaul) and centralizes baseband processing. This shift allows a single core network to control geographically dispersed, low-power remote radio heads (RRHs) via the public internet or private MPLS.
Remote GSMedge provides secure data processing and analysis using SMPC. SMPC enables multiple parties to jointly perform computations on private data without revealing their individual inputs. In Remote GSMedge, the edge devices and the GSMedge server use SMPC to jointly perform computations on sensitive data. remote gsmedge
Operating a remote GSM/Edge transmitter is illegal in most jurisdictions without a license. In the US, the FCC requires Part 22/24 licensing. Unauthorized remote BTSs violate the Communications Act (47 USC § 301) and can be geolocated via wardriving. Researchers must use shielded chambers or test licenses (e.g., amateur radio with modified rules). GSM (Global System for Mobile Communications) and its
However, the philosophy of "Remote GSM Edge" remains vital. While the transport layer is evolving from GSM to NB-IoT, the necessity of processing data at the remote edge—where power is scarce and connectivity is intermittent—will only grow. This shift allows a single core network to

For example, an edge-enabled pipeline monitor in a remote desert doesn't send a continuous stream of pressure readings. It processes the pressure data locally. If the pressure is normal, it stays silent (saving bandwidth). If it detects a spike indicating a leak, it sends a small, compressed alert packet over the GSM network. This overcomes the bandwidth limitations of GSM.
