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, by the wireless access node, a 4.9 GHz radio exclusively for public safety data packets;

selecting, by the wireless access node, other radios for other types of data packets;

selecting, by the wireless access node, other radios for public safety data packets depending upon specification by a network operator; and

specifying, by the network operator, that the public safety data packets are to use an unlicensed band radio if the 4.9 GHz radio is unavailable.

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

selecting, by the wireless access node, a 4.9 GHz radio exclusively for public safety data packets;

selecting, by the wireless access node, other radios for other types of data packets;

selecting, by the wireless access node, other radios for public safety data packets depending upon specification by a network operator; and

specifying, by the network operator, 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.

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

selecting, by the wireless access node, a 4.9 GHz radio exclusively for public safety data packets;

selecting, by the wireless access node, other radios for other types of data packets;

selecting, by the wireless access node, other radios for public safety data packets depending upon specification by a network operator;

providing public safety data packets with preemptive rights to all radios of the wireless access node if triggered by detection an emergency event.

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

selecting, by the wireless access node, a 4.9 GHz radio exclusively for public safety data packets;

selecting, by the wireless access node, other radios for other types of data packets;

selecting, by the wireless access node, other radios for public safety data packets depending upon specification by a network operator;

providing public safety data packets with preemptive rights to all radios of the wireless access node if the 4.9 GHz radio is unavailable.

5. 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;

wherein the network operator specifies that the public safety data packets are to use an unlicensed band radio 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;

wherein the network operator specifies 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.

7. 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;

wherein public safety data packets are provided with preemptive rights to all radios of the wireless access node if triggered by detection an emergency event.

8. 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;

wherein public safety data packets are provided with preemptive rights to all radios of the wireless access node if the 4.9 GHz radio is unavailable.

9. 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, wherein the network operator specifies that the public safety data packets are to use an unlicensed band radio if the 4.9 GHz radio is unavailable, or if the 4.9 GHz radio provides lower quality performance than an unlicensed band radio.
