Hybrid power line wireless communication system
In a hybrid communication system a wireless communication link is maintained between a power line communication medium and a non-power line communication medium. Wireless communication is established within an unlicensed frequency band and monitored for quality. If the quality falls below a threshold, a wireless communication link is established within a licensed frequency band. The wireless link may be maintained between a power line communication system (PLCS) backhaul point and an internet protocol (IP) network access point, and/or between a PLCS endpoint communication interface and a premises communication device.
1 . A method of using a communications device, comprising:
establishing a first wireless communication link using an unlicensed frequency band;
assessing the quality of the first wireless communication link to determine whether the quality is below a threshold quality; and
if the assessed quality is determined to be below the threshold quality, establishing a second wireless communication link using a licensed frequency band.
2 . The method of claim 1 , further comprising:
transmitting a command over the first wireless communication link, and wherein said command is a command to communicate via the licensed frequency bad.
3 . The method of claim 1 , further comprising:
receiving data over the first wireless communication link; and
transmitting said received data over a medium voltage power line.
4 . The method of claim 1 , further comprising:
repeating said assessing to monitor the quality of the first wireless communication link.
5 . The method of claim 1 , further comprising:
receiving data over the second wireless communication link; and
transmitting said received data over a medium voltage power line.
6 . A method of providing wireless communication, comprising:
establishing a first power line communication link;
establishing a first wireless communication link with a first frequency band;
communicating data over the first power line communication link and the first wireless communication link;
monitoring the quality of the wireless communication link to determine whether the quality is below a threshold quality; and
if the monitored quality is determined to be below the threshold quality, establishing a wireless communication within a second frequency band.
7 . The method of claim 6 , wherein said first frequency band comprises an unlicensed frequency band and said second frequency band comprises a licensed frequency band.
8 . The method of claim 7 , further comprising after establishing wireless communication within the second frequency band:
monitoring the first frequency band to determine whether the first frequency band satisfies a set of predetermined performance parameters; and
when the monitored first frequency band is determined to satisfy the set, establishing wireless communications within the monitored first frequency band.
9 . A method of communication in a hybrid communication system having a backhaul point and an endpoint communication interface, comprising:
establishing a first power line communication link between a first and second medium voltage access device;
maintaining a first wireless communication link between the first medium voltage access device and a first wireless node;
wherein said maintaining comprises:
establishing the first wireless communication within an unlicensed frequency band;
monitoring the quality of the wireless communication;
determining whether the quality is below a threshold quality; and
establishing the first wireless communication link within a licensed frequency band if the quality is determined to be below the threshold quality.
10 . The method of claim 9 , in which said maintaining comprises:
wherein the between the first medium voltage access device comprises a backhaul point.
11 . The method of claim 10 , further comprising:
receiving a first communication at the backhaul point over the first wireless communication link;
routing the first communication over the power line communication link to the second medium voltage access device; and
transmitting the first communication to a user device.
12 . The method of claim 11 , wherein said transmitting comprises:
receiving the first communication from the power line communication link; and
transmitting the first communication over a second wireless communication link to wireless modem communicatively coupled to the user device.
13 . The method of claim 12 , wherein said unlicensed frequency band is a first unlicensed frequency band, wherein the licensed frequency band is a first licensed frequency band, and further comprising:
establishing the second wireless communication link within a second unlicensed frequency band;
monitoring the quality of the second wireless communication link;
determining whether the monitored quality of the second wireless communication link is below a threshold quality; and
establishing the second wireless communication link within a second licensed frequency band when the monitored quality is determined to be below the threshold quality.
14 . The method of claim 13 wherein the first unlicensed frequency band is the same as the second unlicensed frequency band.
15 . The method of claim 13 wherein the first licensed frequency band is the same as the second licensed frequency band.
16 . The method of claim 9 , wherein the first medium voltage access device comprises a bypass device.
17 . The method of claim 16 , further comprising:
receiving a first communication from a user device at the bypass device over the wireless communication link;
sending the first communication over the first power line communication link to the second MV access device; and
transmitting the first communication to an uplink node from the second MV access device.
18 . The method of claim 17 , wherein said transmitting comprises:
receiving the first communication from the power line communication link; and
transmitting the first communication over a second wireless link to the uplink node.
19 . The method of claim 9 , wherein the steps are performed by a bypass device.
