Solution:
A Triumphant Combination of Technologies
The network is comprised of several innovative solutions from JMA Wireless. Its multi-band, multi-carrier TEKO DAS provides cellular coverage and capacity for the 700, 1900 and 2100 bands currently. Furthermore, this future-proof offering includes remote units (RUs) and head-end equipment that are AWS-3 ready.
This 15-sector system is comprised of 76 low-power, five-band remote units and four high-power, five-band remote units. In addition, 88 ODAS (outdoor DAS) antennas were deployed throughout this massive motor-sports complex. These antennas include a combination of directional and omni-directional solutions providing either 1X2 or 2X2 MIMO (multiple input, multiple output). However, in the main grandstand XGU-FRO-230 antennas were deployed to ensure mobile communications for the thousands of spectators often just seated in this area. These antennas with Fast Roll-Off (FRO) technology ensure increased data throughput without compromising coverage. The horizontal beam produced by FRO technology increases the Signal to Interference and Noise Ratio (SINR) by eliminating overlap between sectors. The enhanced SINR results in higher throughput, which is particularly critical during major racing events. Furthermore, the horizontal beam produced by Fast Roll-Off technology reduces harmful interference between adjacent cells, making them especially useful in dense environments. These antennas do not only provide a small unobtrusive footprint, but also are quite durable and can withstand winds up to 120 mph. Finally, the deployment at Sonoma Raceway features the latest technology from JMA Wireless, which effectively eliminates PIM from the wireless network.
JMA Wireless solutions are effective and cost efficient too. Each remote unit only requires a single fiber to deliver multiple bands as well as connect it to the master unit (MU). The master unit provides a single administrative interface for configuring and upgrading remote units with new firmware.
The JMA Wireless FUZE™ technology was deployed to provide further cost savings. Its digital electricity feature allowed power to be centralized in three different locations – the head-end room and two outdoor cabinets. It powers various remote units and antennas a quarter mile away.

electricity to antennas and remote units deployed in the far reaches of the
