Situation

The police, fire departments and public utilities providers of the mountainous City of San Luis Obispo, California, had been relying on a 30-year-old analog public safety radio network. The challenging terrain meant that portable hand-held service was particularly unreliable.

Steve Schmidt，Slo It Manager在紧急情况下说，第一个响应者必须在物理上离开紧急情况并开车，直到他们建立无线电通信来要求备份。“更糟糕的是，他们会用他们的手机沟通。这只是不可接受的 - 人民的生活有风险。“

The City is also contracted to provide fire service for the California Polytechnic State University campus and student residences.

In 2009, the City decided to replace the old analog network with a new network that could provide reliable, secure city-wide coverage, encourage increased co-operation between police, SWAT, fire, city and dispatch teams, and make use of existing fiber infrastructure.

回复

Tait experts worked closely with the City to design a solution that addressed the challenges of the terrain, without compromising reliability, by carefully selecting three geographically diverse radio sites to reduce risk of network failure. The solution was also designed to re-utilize the existing fiber infrastructure.

该解决方案是六个基于IP的Taitnet QS2 Simulcast / P25传统的Simulcast网络，用于城市警察，SWAT，Fire，Public Works和Utility部门。混合解决方案旨在与位于紧急通讯中心的Avtech IP的控制台设备接口。

The network deployment in 2010 was managed by qualified Tait professionals. "Project Management was great," says Steve Schmidt. "They kept everything on time and there were no delays with installation."

Commissioning, Technical Training and support are provided by Tait Services experts on an ongoing basis.

结果

Coverage tests show that SLO now has 98.5% city-wide coverage on portable and mobile radios, as well as 100% network redundancy via re-use of the City’s fiber infrastructure, giving first responders confidence in their communications. The resilient Tait P25 radio system has solved all of the previously identified coverage issues.

"With the new state-of-the-art Tait network, our city workers feel confident now with their communications equipment," says Steve Schmidt. "The system has solved all of the coverage issues we had in the City and out at the Cal Poly campus."

The Simulcast cross-band, city common channel means that communication between police, fire, utility and public works is fully interoperable, enabling radio users to work together seamlessly to manage large events or emergencies.

A P25 digital encrypted channel, utilizing the FIPS-certified 140-2 Advanced Encryption Standard (AES), ensures that police and SWAT operations are carried out in complete secrecy, improving safety of staff and the community.
