In Washington D.C. today, Globalstar demonstrated a wireless phone that can use the same radio spectrum to connect to both satellite and terrestrial communications networks. The new technology permits call capacity to be managed and reallocated in real time between satellite and terrestrial networks. New ground-based networks will supplement existing satellite service, to provide a 'back-up' signal in and around buildings where satellite signals cannot reach. The system was demonstrated using a modified Telit Model 650 phone.
