摘要： Methods and systems described herein relate to broadcasting on a wireless channel. An example method includes generating, based on data, a data signal including one or more data packets, where each of the one or more data packets is a non-connectable and non-scannable data packet. The method further includes generating a plurality of RF signals of different frequencies using an oscillator circuit, directly modulating at least one of the RF signals, based on the data signal, to generate a modulated RF signal, amplifying the modulated RF signal, and broadcasting the amplified modulated RF signal on the wireless channel.

摘要： To provide a voltage controlled oscillator having small size and capable of obtaining a low phase noise characteristic over a large span of adjustable range of frequency. A quartz crystal having a characteristic (dielectric loss tangent: tan δ) better than that of fluorocarbon resin, LTCC or the like conventionally used as a substrate of a resonance part, and on which a fine pattern of metal film can be formed through a photolithography method, is used as a quartz-crystal substrate, and a conductive line is formed on the quartz-crystal substrate to form an inductance element in the resonance part. Accordingly, since the resonance part having a high Q value can be formed, it is possible to obtain a voltage controlled oscillator having small size and low loss over a wide frequency range.
