Frequency Coordination for Trade Shows
Providing Spectrum Management Solutions is Our Business

A growing number of trade show exhibitors are demonstrating wireless products and more and more trade show attendees are operating multiple wireless devices-resulting in RF interference between devices and even to surrounding cellular networks. Minimizing interference conflicts between wireless devices and providing a quality experience for both exhibitors and attendees is crucial to the success of wireless trade shows.

Comsearch has been helping trade show organizers implement successful frequency coordination plans for their shows for over five years. As the "Official Frequency Coordinator" for the CTIA Wireless shows, Comsearch's proven expertise and experience enables exhibitors to demonstrate their devices without the threat of causing or receiving harmful RF interference.

Comsearch implements a frequency coordination process that consists of pre-show coordination and on-site interference protection.

Pre-Show Frequency Coordination

Wireless Device Registration: Exhibitors register wireless devices that will be demonstrated and operated on the exhibit floor. Comsearch reviews all device registrations and recommends frequencies that will avoid harmful interference. Comsearch pays particular attention to protecting licensed wireless operators in the vicinity of the convention center.

PCS and 3G Device Coordination: Exhibitors who require spectrum in 1.9 GHz and 2.1 GHz bands must coordinate with incumbent PCS and microwave licensees. Comsearch utilizes our engineering expertise and our industry-acclaimed comprehensive databases and tools as well as our long-standing relationships with PCS licensees to recommend and coordinate spectrum between the exhibitors and the incumbents (PCS and microwave licensees).

Unlicensed Spectrum Coordination: Comsearch will provide registered exhibitors demonstrating Wi-Fi technology or other unlicensed devices with a color-coded show floor map, identifying/highlighting wireless emitters operating within the same frequency band. With this information, exhibitors can identify and resolve potential interference conflicts before they happen.

On-Site Interference Monitoring Before and During the Show

Pre-Show Measurements: Prior to the opening of the show, Comsearch engineers will perform on-site interference monitoring to identify the operational incumbent carrier signals and any undesired emissions. This is used as a baseline for measurements taken during the show.

Show Monitoring: During the first hours of the show, our engineers will identify any additional RF signals and crosscheck those signals with the list of registered exhibitors that plan to transmit. Comsearch engineers continuously perform random spectrum sweeps during the show and report anomalies to show management.
