1. A method of broadcasting an advertisement event on a wireless channel, the method comprising:
- generating, based on data, a data signal comprising one or more data packets, wherein each of the one or more data packets is a non-connectable data packet;
generating a radio frequency (RF) signal using a single oscillator circuit and a single chip separate from the single oscillator circuit, wherein the single chip comprises (i) a plurality of thin-film bulk acoustic resonators (FBARs), (ii) a first contact pad coupled to each FBAR of the plurality of FBARs, wherein the first contact pad is coupled to a ground of the single oscillator circuit such that each FBAR of the plurality of FBARs is coupled to the ground of the single oscillator circuit via the first contact pad, and (iii) a plurality of second contact pads each coupled to a respective FBAR of the plurality of FBARs;
directly modulating the generated RF signal, 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, wherein the amplified modulated RF signal is associated with the advertisement event.

Abstract
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.
