Many Bluetooth Low Energy (BLE) advertising devices operate primarily in a transmit-only mode. Prior to start of transmissions, such devices do not test for the presence of other BLE devices that might currently be occupying the spectrum. To minimize collisions, such BLE transmitters add randomness to transmit timing. This technique fails when too many advertisers are in a confined area, as the chance of collisions goes up with the number of advertisers. This disclosure describes managed adaptive spectrum sharing for BLE (MASS BLE), a technique that uses time division multiple access to enable co-located BLE advertisers to share spectrum with graceful degradation of functionality.
