HamGeek CZE-15A 15W Bluetooth FM Transmitter Stereo Audio Wireless Broadcaster Transmitter

* This product can be connected to any device with an audio output. Whenever high-fidelity audio needs to be transmitted wirelessly, this product can be used to achieve that.

* Compatible devices include: TVs, desktop computers, laptops, MP4/MP5 players, MP3 players, mobile phones, mobile phones for iPhones, and iPads.

* The transmitter also supports projectors, audio and video playback devices, and other similar equipment.

* The transmitter broadcasts the movie's audio signal via FM, allowing vehicles to receive the audio through their built-in FM radios.

* Required Equipment: FM transmitter + 1/4-wavelength antenna + microphone

* Music is transmitted via the FM transmitter and received by FM receiver speakers, which can be installed at any suitable location with access to AC power, provided the FM signal can be received.

* Required Equipment: FM transmitter + FM receiver speakers (N units) + 1/4-wavelength antenna + microphone

* Audio is transmitted via the FM transmitter and received by FM receiver speakers installed around the campus or through FM radio receivers on mobile phones that support FM radio reception.

* Required Equipment: FM transmitter + FM receiver speakers + mobile phones with FM radio reception capability

* Install the transmitter in the lead vehicle. Drivers in the other vehicles can tune their FM radios to the transmitter's frequency to listen to music, announcements, instructions, and other information broadcast from the lead vehicle. Audio quality is significantly better than that of a conventional walkie talkie.

* Required Equipment: FM transmitter + vehicle-mounted antenna + microphone

* Install FM receiver speakers in workshops, restrooms, outdoor activity areas, and other locations throughout the factory to enable facility-wide broadcasting for locating personnel, making announcements, and playing music.

* Required Equipment: FM transmitter + 1/4-wavelength antenna + microphone + FM receiver speakers

* The higher the transmitter's output power, the greater the potential transmission range.

* Electromagnetic waves in the FM band propagate approximately in straight lines, much like light. When the signal encounters obstacles, its transmission range can be significantly reduced. Therefore, mounting the antenna higher helps reduce obstructions and can extend the transmission range.

* Antenna gain indicates how effectively an antenna concentrates radio-frequency energy in a particular direction. Higher gain can improve signal strength in the intended direction and extend the effective transmission range.

* As mentioned above, FM-band electromagnetic waves propagate approximately in straight lines. If tall buildings or other obstacles block the path between the transmitting and receiving antennas, the transmission range may be significantly reduced.

* Receiver sensitivity is another important factor. If the receiver has poor sensitivity, even a powerful transmitter may not provide reliable reception. Higher receiver sensitivity generally allows weaker signals to be received.

* A noisy electromagnetic environment can introduce interference that affects the receiver's ability to receive the signal. This is similar to trying to hold a conversation in a noisy nightclub, where background noise makes it difficult to hear clearly.

* Many other factors can also affect transmission range, including antenna type, antenna orientation, terrain, frequency, and local interference conditions.

* In general, transmission range is not specified as a fixed performance parameter for transmitters because it depends on multiple factors. Quoting a transmission range without considering the actual operating environment is therefore unrealistic. Actual performance will vary depending on the installation, antenna configuration, receiver characteristics, and surrounding conditions.
