<p><a href="https://lcantennas.com/what-is-the-ism-band/">What is the ISM band</a> and what are the main frequencies in the ISM band? After the read, you will get the answer.</p> <p>This frequency range for <a href="https://lcantennas.com/433mhz-antenna-sma/">430.050 ~ 434.790MHz</a>, in the world range, to allocate to the amateur radio service use, the frequency band is roughly located in the middle of the amateur radio band, at present has been various ISM application occupied.</p> <p>This frequency range belongs to the <a href="https://lcantennas.com/omnidirectional-uhf-antenna/">UHF band</a>, where electromagnetic waves will show significant attenuation and reflection when they encounter buildings or other obstacles.</p> <p>In this band, due to the many applications, the mutual interference of ISM is relatively large. Many domestic RFID also use this <a href="https://lcantennas.com/uhf-omnidirectional-antenna/">UHF frequency</a>.</p> <p>This frequency range is from <a href="https://lcantennas.com/lorawan-antenna-868/">868 to 870 MHz</a>, in the UHF band. Since 1997, this frequency band in Europe allows the use of short-range devices, so it can also be used as an RFID frequency.</p> <p><a href="https://lcantennas.com/lora-gateway-antenna-3dbi/">915 MHz</a></p> <p>In the United States and Australia, the frequency range <a href="https://lcantennas.com/lorawan-antenna-868-mhz/">888 to 889 MHz</a> and <a href="https://lcantennas.com/lorawan-antenna-915mhz/">902 to 928 MHz</a> has been available and used by the backscatter RFID system.</p> <p><a href="https://lcantennas.com/pcb-wifi-antenna/">2.4 GHz</a></p> <p>This ISM band frequency range is <a href="https://lcantennas.com/ipex-wifi-antenna/">2.400 ~ 2.483GHz</a>, belongs to the microwave band, also in the UHF band, and amateur radio enthusiasts and radiolocation services use the frequency range partly overlap.</p>
