洛杉矶区域互操作通信系统(LA-RICS)的P25网络部署工作仍继续,据洛杉矶区域互操作通信系统(LA-RICS)执行董事斯科特·埃德森(Scott Edson)说,陆地移动无线电(LMR)项目因去年的一系列事件而被进一步推迟,目前已落后计划约三年

埃德森说,去年,LA-RICS与摩托罗拉解决方案公司(Motorola Solutions)签订了完成窄带LMR系统的合同,但该网络的60个站点中只有46个完成了。他说,现,摩托罗拉解决方案公司完成P25系统和LA-RICS接受新LMR网络的目标日期已经推到2023年

埃德森接受IWCE紧急通讯部的采访时说:“我们本应该现就完成,但火灾、洪水、流行病、资源、供应链问题以及一些可预防的延误进一步推迟了项目的实施。”

埃德森拒绝详细说明他提到的“可预防的延误”

一旦一个小区站点得到优化和测试,LA-RICS成员机构就能够利用P25网络80%的覆盖率,但摩托罗拉解决方案完成所有60个站点之前,他们将无法完全切换到区域LMR网络并使其各自现有的无线电系统退役,埃德森说

部署P25对LA-RICS来说是一个挑战,它已经追求这个目标十多年了。2010年开始的竞标过程中,LA-RICS首次将6亿美元的LMR和LTE网络授予雷神公司后,2011年发现的法律技术问题导致>

Efforts to deploy the P25 network for the Los Angeles Regional Interoperable Communications System (LA-RICS) are continuing, with the land-mobile-radio (LMR) project is about three years behind schedule after being delayed further by a confluence of events last year, according to LA-RICS Executive Director Scott Edson.

LA-RICS had contracted with Motorola Solutions to finish the narrowband LMR system last year, but only 46 of the 60 sites for the network are done, Edson said. Now, the target date for Motorola Solutions to complete the P25 system and for LA-RICS to accept the new LMR network has been pushed to 2023, he said.

“We were supposed to be done by now, but fires, floods, the pandemic, resources, supply-chain issues and some preventable delays have further delayed the program,” Edson said during an interview with .

Edson declined to elaborate on the “preventable delays” he referenced.

Once a cell site is optimized and tested, LA-RICS member agencies are able to leverage the coverage provided by the 80% of the P25 network that is done, but they will not be able to completely switch to the regional LMR network—and retire their respective existing radio systems—until Motorola Solutions has finished all 60 sites, Edson said.

Deploying P25 has proven to be challenging for LA-RICS, which has been pursuing the goal for more than a decade. After LA-RICS first awarded a $600 million both the LMR and LTE networks to Raytheon in a bidding process initiated in 2010, a legal technicality uncovered in 2011 resulted in both systems being procured separately.

When the LMR project was rebid, Motorola Solutions was select and signed a contract with LA-RICS for the LMR system in August 2013. Motorola Solutions subsequently also was chosen to build the LTE network, signing a contract to deploy the LA-RICS broadband wireless in March 2014.

The scope of both the P25 and LTE networks for LA-RICS were reduced significantly in 2015—largely by redesign on the LTE side in the spring of that year, in part because of claims of RF dangers from the local firefighters’ union. The 232-site LTE plan was pared to 77 sites and eventually 76 sites. In 2018, the 76 sites were transferred to AT&T for FirstNet, and LA-RICS later built another 26 LTE sites that were transferred to AT&T for the FirstNet initiative.

Meanwhile, the LA-RICS P25 project was reduced from more than 80 sites to 60 sites, in part because the city of Los Angeles opted to pull out of the regional initiative in November 2015.
