1. In a mobile communication device, a method of beginning a data communication between the mobile communication device and a communication network, the method comprising:
- selecting between a plurality of alternative medium access techniques for the data communication;
waiting a period of time that is at least as long as a predetermined time period and determining that a wireless communication channel is available for communication;
after said waiting and determining, attempting, over the wireless communication channel, to initiate data communication to the communication network;
determining whether the attempt to initiate data communication to the communication network was successful by, at least in part, receiving a message from the communication network indicating that the mobile communication device is to wait for another message from the communication network before communicating data to the communication network; and
if the attempt to initiate data communication to the communication network was successful, then transmitting a series of packets to the communication network, where each two consecutive packet transmissions are separated by no more than the predetermined time period.

Abstract
Disclosed herein is a redundant network and communication protocol at least including host computers, RF base stations, and roaming terminals. The network may utilize a polling communication protocol such that under heavy traffic conditions, a roaming terminal wishing to initiate communication may be required to wait for at least a predetermined period and determine whether the channel is available for communication. When a hidden terminal is communicating, the roaming terminal may conclude that the communication is taking place upon receiving a polling frame directed to the hidden terminal from the normally silent base station. Inherent redundancy techniques may be used with a spanning tree approach for determining the most efficient pathways from a source to a destination and ensuring that the network adapts to spatial changes or breakdowns within the network.

1. In a mobile communication device, a method of beginning a data communication between the mobile communication device and a communication network, the method comprising:
-
selecting between a plurality of alternative medium access techniques for the data communication; waiting a period of time that is at least as long as a predetermined time period and determining that a wireless communication channel is available for communication; after said waiting and determining, attempting, over the wireless communication channel, to initiate data communication to the communication network; determining whether the attempt to initiate data communication to the communication network was successful by, at least in part, receiving a message from the communication network indicating that the mobile communication device is to wait for another message from the communication network before communicating data to the communication network; and if the attempt to initiate data communication to the communication network was successful, then transmitting a series of packets to the communication network, where each two consecutive packet transmissions are separated by no more than the predetermined time period. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

22. In a mobile communication device, a method of beginning a data communication between the mobile communication device and a communication network, the method comprising:
-
waking from a sleep state to receive a message from the communication network; after waking, selecting between a plurality of alternative medium access techniques for the data communication; waiting a period of time that is at least as long as a predetermined time period and determining that a wireless communication channel is available for communication; after said waiting and determining, attempting, over the wireless communication channel to initiate data communication to the communication network; determining whether the attempt to initiate data communication to the communication network was successful by, at least in part, receiving a message from the communication network indicating that the mobile communication device is to wait for another message from the communication network before communicating data to the communication network; and if the attempt to initiate data communication to the communication network was successful, then transmitting a series of packets to the communication network where each two consecutive packet transmissions are separated by no more than the predetermined time period.
