This option is a major improvement over the basic LTR architecture. GE-MARC control channels when busy will emit data packets sending the field radios to another channel when busy with any activity on the input or monitor channel. This activity can either be a system customer or a user on a third party system. All manufacturers basic LTR radios are compatable with this and is invisible to the system user. We found this to be very helpful in high RF environments such as the New York Metro area

Research Research Topics of Radio Communication Systems Radio Resource Management in Wireless Systems The main emphasis is on studying schemes to handle and to avoid interference in order to make efficient use of the scarce natural resource radio spectrum. Of particular interest is radio resource management for multi-service, multi radio access systems offering access over a multitude air interfaces and access networks. Also non-cooperative ("user centric") RRM is of significant interest. Low Cost Wireless Infrastructures The LCI project aims at studying key problems in the architecture and deployment of future wireless access infrastructures required to provide Personal Multimedia communication to all at the same cost as fixed telephony today. Ad hoc Radio Networks Ad-hoc networking attacks a number of todays critical problems, infrastructure cost, roll out time and the limited radio ranges associated with higher frequency bands and higher data rates. The project focus on on the radio environment and radio resource management, factors that have often simplified in previous studies. OFDM for Mobile Communications Systems OFDM allows high data rate transmission and the possibility of maximizing its efficiency by adapting its variables to the channel behaviour. We are looking at the potential of OFDM when combined with variable rate modulation and trellis coded modulation.
