FAQ

Q1: What is an ISM band antenna?
A: An ISM band antenna is designed to operate in the Industrial, Scientific, and Medical frequency bands, which are license-free and widely used for wireless communication technologies such as WiFi, Bluetooth, Zigbee, LoRa, and other IoT devices.

Q2: Are LoRa antennas and general ISM antennas interchangeable?
A: They can be used interchangeably if the frequency range matches. However, LoRa antennas are often tuned for specific LoRa frequency bands and may offer better performance in LoRa-specific applications compared to a general-purpose ISM antenna.

Q3: What frequency bands do LoRa antennas support?
A: Common LoRa frequency bands include 868 MHz (EU), 915 MHz (US), 433 MHz (Asia), and 490 MHz (Japan). It is important to select an antenna that matches the regional frequency plan of your LoRa network.

Q4: What type of connector is commonly used for LoRa and ISM antennas?
A: SMA and RP-SMA connectors are widely used, especially for gateway and device antennas. N-type connectors may also be found in higher-power or outdoor applications.

Q5: What regulations apply to LoRa and ISM antenna use?
A: ISM band usage is subject to regional regulations regarding frequency, transmit power, and duty cycle. Always comply with local radio communication laws when deploying LoRa or other ISM band devices.
