Abstract

Apparatuses and methods of using multiple radios of a wireless access node of a wireless network are disclosed. One method includes selecting a 4.9 GHz radio exclusively for public safety data packets, selecting other radios for other types of data packets, and selecting other radios for public safety data packets depending upon specification by a network operator.

Claims

1. A method of using multiple radios of a wireless access node of a wireless network, comprising:

selecting a 4.9 GHz radio exclusively for public safety data packets;

selecting other radios for other types of data packets;

selecting other radios for public safety data packets depending upon specification by a network operator.

2. The method of claim 1, further comprising the network operator specifying that the public safety data packets are to use an unlicensed band radio if the 4.9 GHz radio is unavailable.

3. The method of claim 1, further comprising the network operator specifying that the public safety data packets are to use an unlicensed band radio if the 4.9 GHz radio provides lower quality performance than an unlicensed band radio.

4. The method of claim 1, further comprising providing public safety data packets with preemptive rights to all radios of the wireless access node if triggered by detection an emergency event.

5. The method of claim 1, further comprising providing public safety data packets with preemptive rights to all radios of the wireless access node if the 4.9 GHz radio is unavailable.

6. A multiple radio wireless access node, comprising:

means for selecting a 4.9 GHz radio exclusively for public safety data packets;

means for selecting other radios for other types of data packets;

means for selecting other radios for public safety data packets depending upon specification by a network operator.

7. The multiple radio wireless access node of claim 6, further comprising the network operator specifying that the public safety data packets are to use an unlicensed band radio if the 4.9 GHz radio is unavailable.

8. The multiple radio wireless access node of claim 6, further comprising the network operator specifying that the public safety data packets are to use an unlicensed band radio if the 4.9 GHz radio provides lower quality performance than an unlicensed band radio.

9. The multiple radio wireless access node of claim 6, further comprising providing public safety data packets with preemptive rights to all radios of the wireless access node if triggered by detection an emergency event.

10. The multiple radio wireless access node of claim 6, further comprising providing public safety data packets with preemptive rights to all radios of the wireless access node if the 4.9 GHz radio is unavailable.

11. A multiple radio wireless access node, comprising:

a plurality of radios;

the multiple radio wireless access node operative to select a 4.9 GHz radio exclusively for public safety data packets;

the multiple radio wireless access node operative to select other radios for other types of data packets;

the multiple radio wireless access node operative to select other radios for public safety data packets depending upon specification by a network operator.
