摘要： Techniques are provided for frequency coordination among two different wireless network protocols, such as the IEEE 802.11 and Bluetooth protocols, operating in proximity with one another. Coordination is accomplished by the use of a first radio transceiver operating in accordance with a first communication protocol (which may be the 802.11 protocol) and using a frequency band (which may be the 2.4 GHz band), a base station connected to a wired network and operating in accordance with the first communication protocol, a second radio transceiver operating in accordance with a second communication protocol (which may be the Bluetooth protocol) and using the frequency band, and a coordinator associated with the base station for, in turn, activating the first radio transceiver, deactivating the first radio transceiver, activating the second radio transceiver, and deactivating the second radio transceiver.

摘要： A portable data input or computer system includes an input/output device such as a keyboard and a display, another data input device such as an optical bar code scanner, and a data processor module. To scan bar code type indicia, the operator points the scanner at the bar code and triggers the scanner to read the indicia. All the system components are distributed on an operator's body and together form a personal area system (PAS). Components may include a scanner or imager, a wrist unit, a headpiece including an eyepiece display, speaker and a microphone. Components within a particular PAS communicate with each other over a personal area network (PAN). Individual PASs may be combined into a network of PASs called a PAS cluster. PASs in a particular PAS cluster can communicate with each other over another wireless communication channel. Individual PAS can gain access to a Local Area Network (LAN) and/or a Wide Area Network (WAN) via an access point. Individual PASs can use devices, such as servers and PCs situated either on the LAN or the WAN to retrieve and exchange information. Individual PAS components can provide automatic speech and image recognition. PAS components may also act a telephone, a pager, or any other communication device having access to a LAN or a WAN. Transmission of digitized voice and/or video data can be achieved over an Internet link.

摘要： A coaxial physical layer device operates in at least two different modes: a discovery mode and a normal mode. In the discovery mode, a first orthogonal frequency-division multiplexing (OFDM) coaxial signal is received that has a preamble including a plurality of first training fields and at least one second training field. Each first training field is shorter than each second training field. In the normal mode, a second OFDM coaxial signal is received that has a preamble including a single training field. The single training field is shorter than an OFDM symbol.

摘要： A method for generating a Physical Layer Convergence Protocol Packet Data Unit (PPDU) having a preamble and a payload for television white space transmission (TVWS) is provided. The symbols of the PPDU each include 128 total (orthogonal frequency-division multiplexing) OFDM tones or 256 total OFDM tones. The preamble includes a signal (SIG) field symbol having 108 OFDM data tones if the symbols of the PPDU include 128 total OFDM tones or having 234 OFDM data tones if the symbols of the PPDU include 256 total OFDM tones. The SIG field symbol indicates at least one of an amount of data in the payload or a length of time that the PPDU will occupy the television broadcast frequency spectrum. The PPDU is generated by down-clocking an 802.11ac signal by a factor so that the bandwidth of the PPDU decreases down to one appropriate for use in a TVWS channel.
摘要翻译：提供了一种用于产生具有用于电视白空间传输（TVWS）的前同步码和有效载荷的物理层汇聚协议分组数据单元（PPDU）的方法。 PPDU的符号各自包括128个总共（正交频分复用）OFDM音调或256个总OFDM音调。如果PPDU的符号包括128个总OFDM音调或具有234个OFDM数据音调，如果PPDU的符号包括256个总OFDM音调，则前导码包括具有108个OFDM数据音调的信号（SIG）字段符号。 SIG字段符号指示有效载荷中的数据量或PPDU将占用电视广播频谱的时间长度中的至少一个。 PPDU是通过将802.11ac信号衰减一个因子来产生的，使得PPDU的带宽减小到适合于在TVWS信道中使用的PPDU的带宽。

摘要： Methods, systems, and/or devices are provided that permit data transmissions over unused television channels. An unused channel within a television broadcast frequency spectrum is first identified. A downclocked waveform (for data transmission) is then generated by applying a factor to a clock that causes a waveform bandwidth to be reduced from a first bandwidth to a second bandwidth, wherein the second bandwidth of the downclocked waveform is less than a channel bandwidth for the identified unused channel. The downclocked waveform may then be configured so that it coexists with a larger waveform having a third bandwidth that is greater than the channel bandwidth. The downclocked waveform is then wirelessly transmitted from the transmitter device over the identified unused channel.
