Oklahoma DPS is a multi-service safety and law-enforcement organization, with approximately 1500 civilian and uniformed employees across the state, including Oklahoma Highway Patrol. Highway Patrol’s troopers are responsible for patrolling the state's 111,994 miles of city, county and state-maintained roads and highways. Field troopers are first responders to emergency situations from traffic collisions to natural disasters and civil disorders.
将客户故事下载为PDFThe issue OK DPS faced was a lack of coverage due to the aging VHF Low-Band System across a third of the state of Oklahoma. As a lot of the areas the Highway Patrol covers are remote and state troopers can be out there alone in their vehicles, these coverage issues were making staying safe and connected challenging.
因此，OK DPS有兴趣了解他们如何为其国家官员提供更完整的无线电覆盖，因此它们可以留在与调度和彼此全州的联系。
在寻找解决方案中，探索了几个选项。OK DPS查看了使用VHF中继站点的现有全级800MHz集群系统。这将解决覆盖问题，但也需要将25,000个终端更改为昂贵的双频模型。
Authorized Tait Dealer Stolz Telecom suggested a more cost-effectiveP25700MHz投票的多播解决方案。这是基于2008年的彻底俄勒冈研究，当国家试图在VHF和700 MHz之间决定时，涉及在广域覆盖测试的范围内进行测试设备。这项调查发现，700MHz覆盖范围和VHF。
“结果，OK DPS让我们访问他们的网站以设计覆盖计划以供考虑。最后，我们介绍了一个解决方案，我们认为将解决问题，涉及35个网站，并覆盖俄克拉荷马州约21万平方英里的三分之一，“Stolz Telecom总裁Robert Stolz说。
Oklahoma’s state troopers now have much more complete two-way radio coverage across the state, thanks to the cost-effective Tait solution Stolz Telecom implemented to plug coverage gaps.
The in-fill coverage solution was faster to design and install, and markedly less expensive than solutions presented by other vendors. The cost for the investigation, design work, supply and configuration of the radio network equipment and user training came down to a fraction of the cost from other providers because of how Tait base stations are engineered.
“在扦插方面，在投票和多铸造方面，一切都在基站完成。这个35个网站项目实际上表明，Tait可以支持大型网络。Tait是唯一一个允许您执行P25 700MHz投票的组播网络的制造商“斯托利先生说，不需要外部选民。
现场技术人员也非常喜欢远程访问和频谱分析仪能力TB9400 Base Station远程诊断问题实时。这节省了有时距离有时5小时的远程位置的时间。
