Channel interference reduction
View Patent ↗A method for data transmission over first and second media that overlaps in frequency includes computing one or more time division multiple access (TDMA) time-slot channels to be shared between the first and second media for data transmission; allocating one or more time-slot channels to the first medium for data transmission; allocating one or more of the remaining time-slot channels to the second medium for data transmission; and instructing transceivers for the first and second media to communicate only in their allocated time-slot channels.
1. An apparatus comprising:
a first wireless transceiver configured to communicate data according to a first wireless protocol;
a second wireless transceiver configured to communicate data according to a second wireless protocol that is different from the first wireless protocol; and
a controller configured to select one of the first and second wireless transceivers to communicate data of both the first and second wireless protocols, wherein the apparatus is configured to encode data of the wireless protocol for the unselected transceiver into data of the wireless protocol for the selected transceiver.
2. The apparatus of claim 1 , wherein the first and second wireless protocols are short-range wireless protocols.
3. The apparatus of claim 1 , wherein the first and second wireless protocols operate using overlapping transmission bands.
4. The apparatus of claim 3 , wherein the first and second wireless protocols are short-range wireless protocols.
5. The apparatus of claim 1 , wherein the first wireless protocol is a Bluetooth protocol.
6. The apparatus of claim 1 , wherein the wireless protocol for the selected transceiver is a wireless local area network (LAN) protocol.
7. The apparatus of claim 6 , wherein the wireless protocol for the unselected transceiver is a Bluetooth protocol.
8. The apparatus of claim 1 , wherein the first wireless transceiver is configured to communicate using a 2.4 Ghz transmission band.
9. The apparatus of claim 1 , further comprising a cellular radio core configured to provide wide area network (WAN) access.
10. A method comprising:
a communication device storing data encoded for a plurality of different wireless protocols, the communication device including a plurality of wireless transceivers, each of which is configured to transmit data according to a corresponding one of the plurality of different wireless protocols;
the communication device selecting one of the plurality of different wireless protocols;
the communication device encoding data of an unselected one of the plurality of different wireless protocols into the selected wireless protocol; and
the communication device transmitting the encoded data using the one of the plurality of wireless transceivers corresponding to the selected wireless protocol.
11. The method of claim 10 , wherein the plurality of different wireless protocols includes one or more short-range wireless protocols.
12. The method of claim 10 , wherein the selected wireless protocol and the unselected one of the plurality of different wireless protocols operate using signals that overlap in frequencies.
13. The method of claim 12 , wherein the selected wireless protocol and the unselected one of the plurality of different wireless protocols are short-range wireless protocols.
14. The method of claim 10 , wherein the selected one of the plurality of different wireless protocols is a Bluetooth protocol.
