C A S E S T U DY Coverage Solutions Powerwave King Street Center Powerwave Increases Employee Productivity and the Publics Safety in Downtown Seattle Government Building The Customer Seattle, Washington is just a stones throw away from Redmond, home base for Microsoft and consequently, the high tech capital of the Paci鍖c Northwest. One of the largest of鍖ce complexes in downtown Seattle is King Street Center, a 700,000 square foot municipal government facility that houses the King County Department of Natural Resources and its various divisions and commissions including the Solid Waste Division, the Commission for Marketing Recyclable Materials, the Water & Land Resources Division and the Wastewater Treatment Division. The Challenge A large percent of the government employees who work at King Street Center rely on a variety of wireless devices to perform their jobs each day. Also, because Seattle is located along a major fault line and has a long history of seismic activity, many locals also view their wireless devices as potential lifelines in the event of an earthquake. When traditional lifelines such as utilities, communications networks and transportation systems are damaged, wireless devices can serve to connect people with desperately needed help and information in emergency situations. Unfortunately, a number of physical obstacles were impeding the successful transmission of clear, strong, reliable wireless signals within King Street Center. These included the concrete, steel and brick materials used to construct the building itself as well as certain architectural details; all of which can be extremely hostile to RF signals. Nearby high-rise buildings were also contributing to the problem by effectively blocking signal transmissions altogether. To satisfy both productivity and public safety issues, it became evident to the building management that their in-building wireless coverage needed to be dramatically improved. In order to achieve this, a signal of 85dBm was required throughout 97%+ of the building. The Wireless Service Provider While the top priority was to cost-effectively achieve inbuilding wireless coverage throughout, King Street Center also wanted to ensure that their employees would be able to continue to use the wireless service providers and services of their choice. These included Nextel iDEN速 services, Verizon cellular services, AT&T Wireless

In essence, what they were seeking was a multiservice wireless network that would allow them to extend all four wireless services throughout the facility. Only Powerwave Technologies had the capability to satisfy this requirement and at the same time, manage all of the complex technical demands and business relationships with the various wireless service providers. The Solution Based upon Powerwaves proven expertise, King Street Center was con鍖dent that the company would be able to deliver an affordable and dependable solution. The 鍖rst phase of the process involved a a thorough on-site survey by Powerwaves highly experienced team of engineers in order to assess the building layout and pinpoint all of the obstacles that needed to be outsmarted. During the second phase of the process, the Powerwave engineering team set about designing the optimum solution for extending wireless coverage to those impeded spaces inside the building where it typically failed. What they ultimately recommended was the installation of four In-Hancer Bi-directional Ampli鍖ers, each one dedicated to extend one of the four public carrier signals. Then, to ensure that the signals were evenly distributed throughout the building, a complete distributed antenna system was recommended using 鍖ber optic and coaxial cables, RF to optic converters, and Powerwaves own patented Tap-In signal taps. Upon approval, the third and 鍖nal phase of the process took place, which involved the rapid implementation of the recommended solution with minimal disruption to workplace activities. Because Powerwave was able to provide a turn-key solution for extending coverage of all wireless service providers throughout King Street Center and handled all aspects of its execution including design, manufacture and installation the job was completed ef鍖ciently and cost effectively. Even more important, employee productivity and their sense of security have greatly increased. Employees no longer lose 92 minutes per day answering voicemail. Callers have immediate access to mobile employees. Key Advantages Unprecedented precision in both uplink and downlink paths with advanced digital gain control, which allows installers or technicians to set DGC levels in 1dB increments. Simpli鍖ed maintenance and repair because all major components, such as uplink and downlink ampli鍖ers, power supply and microprocessor controller are designed for plug-and-play to facilitate quick module replacement. Suitable for all types of environments because units are housed in a painted steel cabinet for indoor environments, but are also available in a stainless steel option for more demanding environments. High system availability through the Powerwave Microprocessor Controller option a device that enables installers or technicians to quickly and easily set, store and change all relevant parameters on site, including automatic gain control, digital gain control, module fault monitoring and battery back-up control. Negligible signal loss over large distances when equipped with Powerwaves 鍖ber-optic upgrade.
