英国内政部官员表示,英国公共安全部门计划在2024年或2025年实现从TETRA到LTE的ESN的过渡

英国内政部官员上周表示,英国(英国)的应急服务机构预计2024年或2025年停止使用航空TETRA LMR系统,届时将完成向LTE推送式解决方案的过渡,即关于延迟太久的紧急服务网络的解决方案内政部官员2019年6月对公共账户委员会表示,它已列入一项应急预算,将航空系统延长至2023年。

“我们最新可能关闭航空的绝对是2025年,我们所要做的就是加快这一日期,以便我们能2024年初关闭它,”Rycroft英国议会公共账户委员会9月10日的听证会上说,是网播的。“如果我们能比那更快关掉,那么很明显我们可以,但我不想给一个约会,然后就不见面了。”

公共账户委员会主席梅格·希利尔形容ESN倡议是“另一个政府失败”,并对Rycroft所引用的项目新时间表表示失望

“仅仅是为了航空公司的合同,我们每年都谈论3.6亿至4亿英镑,”Davinson说。按照目前的汇率,这些数字意味着摩托罗拉解决方案每增加一年的航空运营额就意味着4.644亿美元至5.16亿美元

之前的公共账户委员会会议上,委员会成员对摩托罗拉解决方案公共安全通信过渡的TETRA和LTE双方发挥关键作用表示关注。这次会议上,有几次提到了航空公司和科迪亚克公司,但ESN 35分钟的讨论中没有提到摩托罗拉解决方案

“我们目前正测试Kodiak10,”Davinson说。“从7月份开始,我们的测试环境就有过这种情况。测试进展顺利。这将是我们将明年第二季度发布的产品,作为最终产品的主要产品,所有功能都

“我们用户社区做什么?其中一个挑战是,我们找到真正的工作解决方案之前,用户社区当然存怀疑,因为他们看不见、摸不到、摸不到东西……接下来的几个月里,我们正与一些消防救援服务以及一些警察服务一起工作。他们将拥有这些设备,我们将与他们一起他们即将交付的核心,最终版本,即所谓的Prime,Roundound Q2明年的准备中测试它。”

英国一些人援引ESN相关的诸多延误和预算超支,质疑英国全国公共安全宽带是否值得完成。Rycroft一再坚持ESN项目可以完成,并为第一响应者提供最初设想的通信能力

Emergency-services agencies in the United Kingdom (UK) are expected to stop using the Airwave TETRA LMR system in 2024 or 2025, when the transition to an LTE push-to-talk solution on the much-delayed Emergency Services Network (ESN) is scheduled for completion, officials for the UK Home Office said last week.

“The absolute latest that we could turn Airwave off is 2025, and what we are seeking to do is to accelerate that date, so that we can turn it off by the beginning of 2024,” Rycroft said during a Sept. 10 hearing before the Public Accounts Committee of the UK Parliament, which was webcast. “If we could turn it off even sooner than that, then obviously we can, but I don’t want to give a date which then doesn’t get met.”

Meg Hillier, chair of the Public Accounts Committee, described the ESN initiative to date as “another government failure” and expressed frustration about the new timetable for the project cited by Rycroft.

Home Office officials told the Public Accounts Committee in June 2019 that it had included a contingency budget to extend the Airwave system through 2023. At that time, the UK’s National Audit Office released a report that the ESN project would be £3.1 billion—or $3.999 billion, based on current exchange rates—over its original budget.

Most of this money will go to Motorola Solutions, which owns the Airwave TETRA network.

In addition to providing the incumbent TETRA service through Airwave, Motorola Solutions also owns Kodiak, the carrier-integrated LTE push-to-talk solution that UK Home Office officials are relying on to replace the TETRA PTT service provided by Airwave. In the U.S., Kodiak software powers the cellular push-to-talk services offered by carrier giants AT&T and Verizon.

Davinson said the terrestrial LTE network portion of the ESN—being built by cellular carrier EE—is almost complete.

Davinson also expressed optimism about the hardened Samsung LTE device that is being used for the ESN, describing it as “a really good product.” About 1,000 of these handsets are being trialed through the ESN Direct 2 offering, which uses version 9 of the Kodiak software. Plans call for 5,000 more devices to be distributed in April for testing of a new version of Kodiak-based PTT called Prime for a nine months of trials that would extend through 2021, she said.

“Then there is a road map beyond that, where we will go to successive versions of Kodiak as and when they are released. One of the things that we do have in our contract with Kodiak is that they have an obligation—where the 3GPP standard moves, then within 18 months that standard has to be reflected within the Kodiak software. So that gives us the confidence that it will evolve.”IWCE’s Urgent Communications

Davinson said she believe that such PTT trials will greatly enhance acceptance of the ESN within the UK public-safety community—something that has been a problem to date. While the additional delays in the ESN project are not ideal, Home Office officials now are more confident in the new deployment roadmap and timeline, she said.

“What are we doing with the user community? One of the challenges has been that until we have got a real working solution, of course there is skepticism in the user community, because they cannot see, touch and feel something … Over the course of the next few months, we are working with a number of fire and rescue services and with a number of police services. They will have these devices, and we will be working with them to test it in the run-up to them delivering the core, final release, which is called Prime, roundabout Q2 next year.”

Citing the many delays and budget overages associated with the ESN, some in the UK have questioned whether the UK nationwide public-safety broadband is worth completing. Rycroft repeatedly insisted that the ESN project can be finished and provide first responders with communications capabilities that were envisioned initially.

“There is no alternative; or rather, any alternative would be worse than sticking with this program and ensuring that the emergency services have the sort of network and the sort of equipment that they need,” Rycroft said. “The position of the Home Office is that this will succeed; it must succeed; the emergency services need it.

One touchy subject within the UK has been whether the public-safety agencies or the Home Office ultimately will decide when first responders must switch from Airwave to the ESN. Rycroft said that the Home Office continues to want to let public-safety agencies decide when to make the technology migration but offered a significant caveat during a verbal exchange with Hillier.

Hillier noted the important distinction.

Rycroft said he believes that there will be point when public-safety entities will have abandon Airwave, even if they don’t necessarily want to make the transition.

“In the end, I am sure there will not be universally high levels of enthusiasm for this change; I don’t think you find that for any change in any organization anywhere. So, there will come a point where people will need to look very carefully at their own finances— at the … disincentives for not coming across and literally getting with the program.”

But that timeline has not been met, and other public-safety LTE systems—the FirstNet system in the U.S. and the SafeNet system in South Korea—have gained real-world usage more rapidly. However, those non-ESN systems are not specifically designed to replace LMR communications, which public-safety officials have acknowledged is very difficult challenge for an LTE system, for a variety of reasons.
