WiFi client with hybrid communication capabilities for wireless local area network
View Patent ↗A hybrid wireless client apparatus including: a hybrid client controller, at least one antenna, and a plurality of shared and discrete components coupled to one another to form at least one transmit and receive chain each coupled to the at least one antenna for orthogonal frequency division multiplexed (OFDM) wireless communications with a wireless access point (WAP). The hybrid client controller is coupled to the plurality of shared and discrete components and configured to determine an eligibility of at least one neighboring wireless client node on a wireless local area network (WLAN) as a relay target, and responsive to an affirmative eligibility determination to initiate on the hybrid wireless client apparatus both local communications with the WAP together with a relay of distinct communications between the WAP and the at least one neighboring wireless client node as the relay target.
1. A hybrid wireless station for wireless communications on a wireless local area network (WLAN) having a wireless access point (WAP) and associated wireless stations, and the hybrid wireless station comprising:
at least one antenna;
a plurality of shared and discrete components coupled to one another for form at least one transmit and receive chain coupled to the at least one antenna for wireless communications on a selected communication channel;
a hybrid eligibility module coupled to the plurality of shared and discrete components to determine eligibility of the hybrid wireless station for one of a local mode dedicated to local communications between the hybrid wireless station and the WAP, and a hybrid mode interlacing both the local communications together with relayed communications between the WAP and an identified one of the wireless stations and with the hybrid mode eligibility determination based on both airtime availability on the hybrid wireless station together with additional airtime requirements for the relayed communications and wherein the hybrid wireless station estimates the additional airtime requirements by sniffing existing uplink and downlink communication packets between the WAP and the identified one of the wireless stations for information as to data throughput requirements of the identified one of the wireless stations; and
a hybrid operation module coupled to the plurality of shared and discrete components and responsive to a determination of hybrid mode eligibility by the hybrid eligibility module to initiate a relay of subsequent communications between the WAP and the identified one of the wireless stations without interrupting the local communications.
2. The hybrid wireless station of claim 1 , further comprising:
the hybrid eligibility module coupled to the plurality of shared and discrete components to determine eligibility of the hybrid wireless station for one of a local mode dedicated to local communications between the hybrid wireless station and the WAP, and a hybrid mode interlacing both the local communications together with relayed communications between the WAP acid an identified one of the wireless stations and with the hybrid mode eligibility determination based on both airtime availability on the hybrid wireless station together with additional airtime requirements for the relayed communications and wherein the hybrid wireless station estimates the additional airtime requirements by sniffing packet header information as to at least one of data type or payload size on existing uplink and downlink communication packets between the WAP and the identified one of the wireless stations for information as to data throughput requirements of the identified one of the wireless stations.
3. A method for operating a hybrid wireless station on a wireless local area network (WLAN) including wireless stations associated with a wireless access point (WAP); and the method comprising:
determining eligibility of the hybrid wireless station for one of a local mode dedicated to local communications between the hybrid wireless station and the WAP, and a hybrid mode interlacing both the local communications together with relayed communications between the WAP and an identified one of the associated wireless stations;
determining airtime availability on the hybrid wireless station;
sniffing uplink and downlink communication packets between the WAP and the identified one of the wireless stations, for information as to data throughput requirements of the identified one of the wireless stations;
estimating airtime requirements of the identified one of the wireless stations based on in sniffed in the sniffing act;
identifying the associated wireless station as a relay candidate based on the airtime availability of the hybrid wireless station and the airtime requirements of the identified one of the wireless stations; and
responsive to a determination of hybrid mode eligibility in the determining act;
interlacing both the local communications together with the relayed communications.
4. The method for operating a hybrid wireless station of claim 3 , wherein the sniffing and estimating acts further comprise:
sniffing uplink and downlink communication packet headers between the WAP and the identified one of the wireless stations, for information as to at least one of data type or payload size of said packets; and
estimating airtime requirements of the identified one of the wireless stations based on information sniffed in the sniffing act.
