Wireless base station systems for packet communications

A wireless base station comprising

• cellular telephone wireless transmit/receive interface circuitry for communication with any cell telephone handsets in the vicinity of the wireless base station;
• a packet network interface;
• and
• at least one integrated circuit assembly coupling the cellular telephone wireless transmit/receive interface circuitry to the packet network interface, said at least one integrated circuit assembly providing voice over packet transmission and reception and holding bits defining a process of:
• initially generating packets of real-time information with a source rate greater than zero kilobits per second, and a diversity rate, the diversity rate initially being at least zero kilobits per second;
• forming a value of a criterion based on plural report data representative of quality of transmission to a destination, for transition to a different source rate;
• and
• when the criterion is met, transitioning to the different source rate.
