DATA RATES IN MOBILE RADIO SYSTEMS

摘要

Broadband networks for cellular operation are relatively short range and are deployed with infrastructure to serve the needs of a relatively high density of users. Land Mobile Radio (LMR) networks are relatively long range and deployed with infrastructure to serve a relatively low density of users. Methods are described which enable mobile devices to use an LMR network to coordinate operation of a broadband network to achieve higher data rates or use other aspects of the broadband network.

主权项

1. A method of communicating with a mobile radio device, including:
providing a first network of base stations which use a first bearer having a relatively low data rate, providing a second network of base stations which use a second bearer having a relatively high data rate, receiving location data from the mobile device at a base station using the first bearer, providing a directional beam toward the location of the mobile device at a base station using the second bearer, and transmitting data to or receiving data from the mobile device using the directional beam and the second bearer.
