While Northpoint broadcasts are directional in nature, this does not mean they can not be used for interactive services. Northpoint Technology can be used both for one way services such as television broadcasting, as well as interactive services.
Interactive services function asymmetrically using a frequency linking protocol.
These can be completely wireless or linked with the existing wire-line telephone network. Northpoint interactive services link these two channels asymmetrically. Narrow bandwidth wireless or wireline channels are designated for requests which are fulfilled on wide band Northpoint channels. This allows web pages to be delivered at very high speed. Short transmission distances result in a service latency that is much lower than a satellite based wireless internet service.
