During the House Communications Subcommittee hearing held last week on radio receivers, a key theme was ensuring that systems are more adept at tolerating interference. The relationship between receiver performance and spectrum efficiency was pointed out, as well as how the growing number of deployments of new technologies and services have the potential to adversely impact both new entrants and incumbent players.
Participants noted that the concept of spectrum sharing, as outlined in the PCAST report, becomes much more feasible when there are “clearer fences”, in other words, when there is sufficient protection against harmful interference between systems. Such interference mitigation is a key attribute of the xMax cognitive radio solution. xMax employs a “layered” cognitive approach that allows it to remain on channels with moderate to high levels of interference that would prevent other radio systems from functioning. This increases xMax’s network capacity several-fold over current radio technologies in today’s crowded radio bands.
