Marketing: The intended use is generally for industrial/commercial use and will not be sold to the general public. It will also not be sold through retail establishments or through mail order. It will be sold to OEM customers, qualified dealers and directly to commercial customers. Professional Installation: Since the equipment used in the above reference FCC ID has standard RF connectors, the system must be professionally installed. The installer shall be responsible for ensuring that the proper antenna is employed so that the limits specified in Part 1.1310 are not exceeded. It is intended for industry/commercial use. All the necessary instructions keeping our qualified dealers, commercial customers and professional installers clear of the necessity of professional installation are given in the product user manual. Professional installers will ensure that the equipment is installed following local regulations and safety codes. Professional System Design: Further, Avari Wireless, Inc., its partners and integrators will produce appropriate designs for proper equipment placement and settings. Professional RF design and modelling tools are always used to ensure the system operates within the desired coverage area at the appropriate signal levels. Permission is obtained from spectrum owners and deployment is typically coordinated with those spectrum owners. The equipment is setup, and typically centrally monitored, to ensure that it operates on intended frequencies and power levels and that it covers licensed areas and does not interfere with adjacent spectrum owners.
