• Full-Duplex routing of multiple segments simultaneously, with the result that the MicroNode topology is implemented seamlessly and with no loss in data transfer bandwidth even for those sites remotely located from the company's local service head end.

• Data management and control features, enabling large numbers of users to be multiplexed between MicroNode segments simultaneously. Routing algorithms, with dynamic buffering, enables seamless data transfers between the MicroNodes on the network.

• Point-to-Multipoint distribution, through the use of virtual dedicated wireless links, that provide for multiple links to different sites through a single MicroNode device. A single MicroNode can thus serve multiple points, rather than requiring a separate physical link (modem pair) for each link.

The MicroNode technology allows low power RF transmission to be used, so that the system can be safely deployed in electromagnetic-sensitive environments such as hospitals. The system is implemented with simple, low power antennas, one at each customer's location, rather than requiring the use of expensive radio towers. Aero-Vision commenced deployment of MicroNode technology in October, 1996, and has introduced a series of important technology upgrades since that time as part of an on-going Research and Development program.

Frequency re-use is an important feature of the MicroNode technology. Because of the short distances connecting the various MicroNodes within a cell, the same frequency channel can be used many times over in different parts of the cell, providing a high degree of spectrum efficiency. This feature differentiates MicroNode from other wireless technologies, where all users share "broadcast" bandwidth.
