    Abstract: A communication device for allocating tones is described that includes a processor and instructions in memory in electronic communication with the processor. The communication device determines whether a bandwidth for signal transmission is 20, 40, 80 or 160 megahertz (MHz). The communication device respectively allocates tones for 20, 40, 80 or 160 MHz as follows: for a very high throughput (VHT) signal A1 (VHT-SIG-A1): 52, 104, 208, 416; a VHT signal A2 (VHT-SIG-A2): 52, 104, 208, 416; a VHT short training field (VHT-STF): 12, 24, 48, 48; one or more VHT long training field(s) (VHT-LTF(s)): 56, 114, 242, 484; a VHT signal B (VHT-SIG-B): 56, 114, 242, 484; and a data field (DATA): 56, 114, 242, 484. The communication device also transmits the signal.

    Abstract: In an aspect a transceiver is provided. The transceiver may include a plurality of local oscillator (LO) generators configured to generate a plurality of LO signals, respectively, for mixing with one or more communication signals. The transceiver also includes a first synthesizer configured to generate a first reference signal and a second synthesizer configured to generate a second reference signal. The transceiver also includes a distribution circuit. The distribution circuit is configured to switch an input to at least one of the LO generators between the first and second reference signals for tuning each of the at least one of the LO generators between two different LO frequencies and to input to the other ones of the LO generators the first reference signal for tuning each of the other ones of the LO generators to an LO frequency.

    Abstract: Described are a system and method for a first wireless access point to compute timing parameters of neighboring access points based, at least in part, on beacon signals transmitted the neighboring access points. The first wireless access point may the broadcast the computed timing parameters to mobile devices. A mobile device having received the computed timing parameters may then compute an estimate of its location based, at least in part, on subsequently acquired beacon signals transmitted from the first access point and/or neighboring access points.
