Methods and apparatus for facilitating configuration, testing and/or deployment of a wireless system including a wireless extender
Methods and apparatus for facilitating the deployment of a wireless extender in combination with a base station at a customer premises are described. Support is provided for data rate testing in combination with configuring one or more aspects of the system such as wireless extender and/or base station transmission power level. By using testing a system can be deployed where one or more devices may use transmission power levels which are less than the maximum permitted transmission power level while still supporting an expected data rate corresponding to a subscriber service level in a reliable manner. In various embodiments DFS channel black and/or white lists are generated for each link taking into consideration the determined transmit power to be used for a given link.
1. A method, the method comprising:
operating a test server to test a first link using a plurality of different transmission power levels, said testing determining for each of the different transmission power levels a corresponding data rate that is supported by the first link;
determining, based on said testing, a transmission power level to be used on the first link; and
creating a black list of channels, said black list of channels being a list of channels which are not to be used for said first link based on i) said determined transmission power level and ii) transmission power constraints limiting the transmission power which can be used on the channels included in said black list of channels.
2. The method of claim 1 , further comprising:
communicating the black list of channels to a wireless device.
3. The method of claim 2 , wherein said wireless device is a wireless extender.
4. The method of claim 2 , wherein said transmission power level to be used on the first link is a transmission power level supporting a data rate corresponding to a service level to be supported by said first link.
5. The method of claim 4 , wherein determining, based on said testing, the transmission power level to be used on the first link includes:
determining a transmit power level at which the first link fails to satisfy a minimum expected communications data rate corresponding to the service level to be supported by said first link.
6. The method of claim 5 , wherein determining, based on said testing, the transmission power level to be used on the first link further includes:
setting the first link transmit power level to a power level above the determined power level at which the first link fails to satisfy the minimum expected communications data rate corresponding to the service level to be supported by said first link.
7. The method of claim 2 , further comprising:
creating a white list of channels, said white list of channels being a list of channels which are available for said first link based on said determined transmission power level, each individual listed channel on said white list of channels being allowed to use said determined transmission power level without violating a power transmission constraint applicable to the individual listed channel.
8. The method of claim 7 , further comprising:
communicating the white list of channels to the wireless device.
9. The method of claim 8 , wherein said black list of channels and said white list of channels include Dynamic Frequency Selection (DFS) channels, a DFS channel having a corresponding maximum permitted transmit power.
10. The method of claim 9 , wherein DFS channels on the black list of channels have lower maximum transmit power levels than DFS channels on said white list of channels.
11. A test server in a communications network, the test server comprising:
a memory; and
a processor configured to control the test server to:
test a first link using a plurality of different transmission power levels, said testing determining for each of the different transmission power levels a corresponding data rate that is supported by the first link;
determine, based on said testing, a transmission power level to be used on the first link; and
create a black list of channels, said black list of channels being a list of channels which are not to be used for said first link based on i) said determined transmission power level and ii) transmission power constraints limiting the transmission power which can be used on the channels included in said black list of channels.
12. The test server of claim 11 , further comprising:
a transmitter which is controlled by the processor to:
communicate the black list of channels to a wireless device.
13. The test server of claim 12 , wherein said wireless device is a wireless extender.
14. The test server of claim 12 , wherein said transmission power level to be used on the first link is a transmission power level supporting a data rate corresponding to a service level to be supported by said first link.
15. The test server of claim 14 , wherein the processor, as part of being configured to determine, based on said testing, the transmission power level to be used on the first link, is configured to:
determine a transmit power level at which the first link fails to satisfy a minimum expected communications data rate corresponding to the service level to be supported by said first link.
16. The test server of claim 15 , wherein the processor, as part of being configured to determine, based on said testing, the transmission power level to be used on the first link, is further configured to:
set the first link transmit power level to a power level above the determined power level at which the first link fails to satisfy the minimum expected communications data rate corresponding to the service level to be supported by said first link.
17. The test server of claim 16 , wherein the processor is further configured to:
create a white list of channels, said white list of channels being a list of channels which are available for said first link based on said determined transmission power level, each individual listed channel on said white list of channels being allowed to use said determined transmission power level without violating a power transmission constraint applicable to the individual listed channel.
18. The test server of claim 17 , wherein said processor is further configured to:
control the transmitter to communicate the white list of channels to the wireless device.
19. The test server of claim 18 ,
wherein said black list of channels and said white list of channels include Dynamic Frequency Selection (DFS) channels, a DFS channel having a corresponding maximum permitted transmit power; and
wherein DFS channels on the black list of channels have lower maximum transmit power levels than DFS channels on said white list of channels.
20. A non-transitory computer readable medium including processor executable instructions which when executed by a processor of a test server control the test server to:
test a first link using a plurality of different transmission power levels, said testing determining for each of the different transmission power levels a corresponding data rate that is supported by the first link;
determine, based on said testing, a transmission power level to be used on the first link; and
create a black list of channels, said black list of channels being a list of channels which are not to be used for said first link based on i) said determined transmission power level and ii) transmission power constraints limiting the transmission power which can be used on the channels included in said black list of channels.
