An apparatus and a method for routing data in a radio data communication system having one or more host computers, one or more intermediate base stations, and one or more RF terminals organizes the intermediate base stations into an optimal spanning-tree network to control the routing of data to and from the RF terminals and the host computer efficiently and dynamically. Communication between the host computer and the RF terminals is achieved by using the network of intermediate base stations to transmit the data.

1. A communication network supporting wireless communication of messages, said communication network comprising:a first terminal node having a wireless receiver operable in a normal state; a second terminal node having a wireless receiver operable in a power saving state; an access point that attempts to immediately deliver messages destined for the first terminal node; the access point attempts to deliver messages destined for the second terminal node by transmitting at predetermined intervals beacons that identify that a message awaits delivery; the second terminal node synchronizes operation of its wireless receiver to receive the beacons from the access point; and the second terminal node determines from the received beacons that it has a message awaiting delivery and directs further operation of its wireless receiver to receive the message.
