Instead, we propose a novel indoor wireless design paradigm, based on Low Frequency, using the newly freed white spaces previously used as analogue TV bands, and Low Power \u2013 100 times less power than currently used. Preliminary experiments show that this maintains a similar level of connectivity and performance to existing networks. We also advocate full-duplex networking in a single band, which becomes possible in this setting (because we operate at low frequencies). It potentially doubles the throughput of each link and eliminates hidden terminals.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Existing indoor WiFi networks in the 2.5GHz and 5 GHz use too much transmit power, needed because the high carrier frequency limits signal penetration and connectivity.
