Regional Band Plans That Split One Product into Three Variants
Regional spectrum rules force sub-GHz IoT hardware into three distinct SKU builds to optimize front-end matching, maintain link budget, and pass certification.
TELEC AS923
Meaning
Regulatory standards define the technical rules for wireless devices operating in the sub-gigahertz bands within the Asia-Pacific region, with a focus on Japanese compliance. Devices utilizing telec as923 must comply with rules regarding output power, channel spacing, and transmission limits before they can be sold in these countries. This standard ensures that IoT devices do not interfere with other services.
Regional Compliance
Obtaining the official certification requires submitting the hardware to an approved test house that verifies the radio’s performance against the standard. When the device passes these tests, it receives a unique registration number. This number must be printed on the product’s label.
Channel Allocation
System firmware must be configured to use only the allowed frequencies within the band. Since these frequencies differ from those used in Europe or the US, the radio’s frequency plan must be updated for this region. This regional adjustment is done through software configurations.
Hardware Adaptation
Adapting a global product for this market requires selecting antennas and filtering circuits that are optimized for these specific frequencies. If the antenna is not properly tuned, the transceiver’s output power drops and receiver sensitivity suffers, reducing range. These tuning steps ensure the device complies with the regulations while maintaining the reliable wireless range expected by the end user, preventing performance drops and ensuring the hardware works efficiently.
