TN138A 1 915B Radio Operational Requirements INTRODUCTION The Wave Wireless 915B Radio is certified by FCC and Industry Canada (IC) under a Limited Modular Approval (FCC ID: KIN-915B and IC ID: 4309B-915B). This means that the radio can be used in various packages and configurations provided the requirements below are met. These requirements apply to any Wave Wireless final product using the 915B radio.

TN138A 915B Radio Operational Requirements communications. However, there is no guarantee that interference will not occur in a particular installation. All versions of this device have been tested using unshielded Ethernet CAT-5 cable. Notice to User Any changes or modifications to equipment that are not expressly approved by Wave Wireless may void the user’s authority to operate the equipment. 2.1.1 FCC The 915B radio has been designed and manufactured to comply with FCC Part 15 under FCC ID: KIN-915B.

TN138A 915B Radio Operational Requirements intentional radiator is reduced by the amount in dB that the directional gain of the antenna exceeds 6dBi. 3. The operator of a spread spectrum system and the user of the radio device are each responsible for ensuring that the system is operated in the manner outlined in the section on Interference Environment above. The 915B radio with its certified antennas complies with these requirements when installed correctly as detailed in this manual. 2.1.

TN138A 2.2 915B Radio Operational Requirements Final Product Installation Guide Requirements The regulatory notices in sections 2.1.1, 2.1.2, and 2.1.3 must be included in the installation guide for the final product edited as appropriate (e.g. use final product name rather than 915B Radio). As well, the final product installation guide must provide NO instructions on how to remove the 915B radio from the product.

TN138A 2.5 915B Radio Operational Requirements Antennas Only antennas that have been approved by FCC and IC shall be used with the 915B radio. This means that any antenna of the same family with a gain less than or equal to the approved antenna can be used. The list of approved antennas is given in Appendix A, which will be updated as new antennas are approved. The 915B radio is approved for 27.

Antennas of the same type and equal or less gain are permitted to be used.

TN138A 915B Radio Operational Requirements This table shows the cable losses required to use the highest gain antennas of each approved type when mounted indoors. Note that the System EIRP must be no more than 34.8 dBi for an indoor antenna, so that the radiation at a min. separation of 20 cm is within the required safety limits. For practical installations, an antenna of lesser gain is more likely to be used for indoor installations, so this table is a guideline for the worst cases.
