这是英国内政部自去年7月Rycroft担任该组织最高职务以来第四个新的ESN时间表,但Rycroft表示,他对这一时间表更有信心,因为这是通过与将使用公共安全LTE网络的公共安全机构代表加强合作而制定的

Rycroft听证会上说:“我们花了时间这件事上,与未来的用户、供应商做了一个完整的商业案例,与用户和供应商进行了一些非常有力的对话,并提出了一个每个人都能看到的是正确的计划。”,这是网络广播

“道路上不可避免地会有更多的坎坷,这是一个复杂的计划,但时间表中有应急措施,我们决心满足它。”

Rycroft称,急救人员代表此前一直就Airway和ESN进行相关讨论,但内政部制定这一最新时间表时,对公共安全更加关注

他说:“他们(公共安全官员)也参与了此事,但肯定是我参与的头几个月,如果我能这么说的话,我很惊讶他们的声音听起来不像是帐篷里。”我认为我们最近几个月所做的是把他们带回到帐篷里,一部分是移动帐篷,一部分是扩大帐篷,使之成为一个更大的帐篷,这样就有了更多用户的空间,因为他们需要这个产品。”

摩托罗拉解决方案公司(Motorola Solutions)预计将成为对Airwave重新承诺的主要受益者,因为其对Airwave系统的最初三年延期将于2022年底到期,正如摩托罗拉解决方案首席执行官格雷格·布朗(Greg Brown)最近指出的。根据英国每年向摩托罗拉支付4.5亿英镑(6.38亿美元)以维持无线电波系统的运营,一份为期四年的合同,将TETRA网络延长至2026年底,可能为这家LMR巨头带来超过25亿美元的额外收入

摩托罗拉解决方案公司(Motorola Solutions)ESN中也扮演着关键角色,持有该合同,负责领导英国公共安全LTE系统的软件和服务的开发,尽管其获得的资金远低于无线电波服务。这一安排让一些英国官员对摩托罗拉解决方案公司促使TETRA尽快向ESN过渡的动机感到不安

“摩托罗拉这两个阵营都有一只脚,”PAC主席梅格·希利尔听证会上说经过这次耽搁,情况相当不错。”

瑞克罗夫特很快回应了希利尔的声明

“这是我与摩托罗拉首席执行官的一次谈话,团队中的其他人也经常与摩托罗拉的其他人交谈,”Rycroft说我们需要确保他们把最优秀的人才投入到这个项目中,以确保没有人能够做出你暗示的那种指控,即他们正寻求比可能的速度慢,因为他们是通过拖延来赚钱的。他们必须证明事实并非如此,这一点非常重要。”

瑞克罗夫特称,与摩托罗拉解决方案公司的对话可能包括建议该公司与其他公司开展更多合作,以解决未指明的能力问题

“事后诸葛亮的好处是,商业上,有各种各样的事情可以做得不同,”Rycroft说但是,正如他们所说,我们正处我们所处的位置,我们正寻求充分利用我们与现有供应商的关系

“其中一部分是为了确保,我们与摩托罗拉合作,而不是只专注于摩托罗拉自己能做什么,例如,与其他组织合作,填补他们交付该计划的核心基础上可能不如他们强大的能力领域。”

按照最初的提议,英国的第一响应者应该2016年开始使用ESN,并2019年完全过渡,届时TETRA网络将当年最初的电波合同到期后退役。英国国家审计署(NAO)的一位官员表示,由于电波向ESN的过渡推迟到2026年底,英国公共安全通信项目的总估计成本已从2015年的62亿英镑(87.86亿美元)增长到今天的112亿英镑(158.72亿美元)

尽管推迟了8年,预算超支50.86亿英镑(约合72.10亿美元),Rycroft表示,英国公共安全通信向基于LTE的ESN过渡仍有意义

“其他国家正以与我们同样的规模追求这类技术,而以前我们远远领先于他们,”Rycroft说这是一个时机已到的想法。”

Rycroft说,移民执法人员正使用通过ESN提供的LTE一键通功能,一些救护车服务也使用ESN来增强来自电波系统的关键任务通信。此外,据估计,每月有200个紧急呼叫被连接到控制室,因为作为强制ESN覆盖范围的一部分,安装了额外的手机站点,他说

Rycroft说,总体而言,ESN已完成约70%,控制室集成和空对地通信等能力正得到验证。不过,他说,ESN完成之前还有大量工作要做

“我不想假装我们快到了;“我们不是,”莱克罗夫特说这就是为什么我信中明确表示,这一进程将持续到2026年底,但我们正取得进展,我们将不断向你们通报最新情况。”

作为比较,AT&T美国的FirstNet公共安全LTE网络的最初五年建设预计将2023年3月如期完成,并且只需要从频谱拍卖收益中获得70亿美元的联邦资金就可以开始。以平方英里为基础,FirstNet的14频段覆盖率已经是英国地理面积的20多倍,比密歇根州略小,尽管人口密度要大得多

FirstNet支持220万个公共安全连接,并2042年完全自筹资金,预计FirstNet管理局将拥有约150亿美元的自由支配资金,从与AT&的协议来看,未来20年内加强该网络;利用14兆赫频段

United Kingdom (UK) first responders are expected to use the TETRA-based Airwave system owned by Motorola Solutions for at least five more years, as the end of 2026 is the new target date for transitioning to the much-delayed, over-budget Emergency Services Network (ESN), according to a Home Office official.

Home Office Permanent Secretary Matthew Rycroft made the statements about the latest ESN “reset”—a roughly two-year delay compared to the “overambitious” target of late 2024 or early 2025 proposed last fall—during a hearing today before the UK Parliament’s Public Accounts Committee (PAC).

This represents the Home Office’s fourth new ESN timetable since Rycroft assumed the top job at the organization last July, but Rycroft said he is more confident about this schedule, because it was established through greater cooperation with representatives of the public-safety agencies that will be using the public-safety LTE network.

“We have taken the time on this one to do a full business case with the future users, with the suppliers, to have some very robust conversations with users and suppliers, and to come up with a plan that everyone can see is the right one,” Rycroft said during the hearing, which was webcast.

“There will be further bumps in the road inevitably—it’s a complex program—but there is contingency built into that timetable, and we are determined to meet it.”

First-responder representatives previously have been in relevant discussions about Airwave and the ESN, but the Home Office was much more attentive to public safety when preparing this latest timetable, according to Rycroft.

“They [public-safety officials] have been involved, but certainly in the first months of my involvement, I was struck that they weren’t sounding as if they were inside the tent, if I can put it that way,” he said. “I think what we have done in recent months is to bring them back into the tent—partly by moving the tent and partly by expanding it, making it a bigger tent, so there was space for more users, because they need this product.”

Motorola Solutions is expected to be the primary benefactor from the renewed commitment to Airwave, as its initial three-year extension of the Airwave system is due to expire at the end of 2022, as Motorola Solutions CEO Greg Brown noted recently. Based on the 450 million pounds ($638 million) per year that the UK pays Motorola to keep the Airwave system operational, a four-year contract to extend the TETRA network until the end of 2026 could generate more than $2.5 billion in additional revenue for the LMR giant.

Motorola Solutions also plays a key role in the ESN, holding the contract to lead the development of software and services for the UK’s public-safety LTE system, although for much less money than it receives for Airwave services. This arrangement has made several UK officials uncomfortable about Motorola Solutions’ incentive to make the TETRA-to-ESN transition happen as quickly as possible.

“Motorola has a foot in both camps,” PAC Chair Meg Hillier said during the hearing. “It’s doing rather well out of this delay.”

Rycroft quickly responded to Hillier’s statement.

“That is a conversation that I have had with the chief executive at Motorola and that others on the team have with others at Motorola very regularly,” Rycroft said. “We need to ensure that they are putting their very best people onto this program to ensure that no one could make the sort of allegation that you have hinted at—that they are seeking to go slower than they might, because they are making money out of delay. It is really, really important that they demonstrate that that is not the case.”

Conversations with Motorola Solutions may include suggestions that the vendor work more with other companies to address unspecified capabilities, according to Rycroft.

“With the benefit of hindsight, there are all sorts of things commercially that could have been done differently,” Rycroft said. “But we are where we are, as they say, and we are seeking to make the most of the relationships we have with the existing suppliers.

“Part of that is to ensure that, rather than just concentrating on what Motorola can do themselves, we work with Motorola to partner with other organizations—for instance, to fill areas of capability where they’re perhaps not as strong as they are on the core basics of delivering this program.”

As initially proposed, UK first responders were supposed to begin using the ESN in 2016 and transition completely in 2019, when the TETRA network would be retired upon the expiration of the original Airwave contract that year. With the Airwave-to-ESN transition delayed until the end of 2026, the total estimated cost of the UK public-safety communications program has grown from 6.2 billion pounds ($8.786 billion) in 2015 to 11.2 billion pounds ($15.872 billion) today, according to an official with the UK National Audit Office (NAO).

Despite the eight-year delay and 5.086-billion-pound ($7.210 billion) budget overage, Rycroft said transitioning UK public-safety communications to the LTE-based ESN continues to make sense.

“Other countries are pursuing this sort of technology at the same sort of scale as us, whereas previously we were way ahead of them,” Rycroft said. “This is an idea whose time has come.”

Rycroft said that Immigration Enforcement personnel are using the LTE push-to-talk functionality available through ESN, and some ambulance services also are using ESN to augment the mission-critical communications from the Airwave system. In addition, an estimated 200 emergency calls per months are being connected to control rooms because of the additional cell sites that have been installed as part of mandated ESN coverage, he said.

Overall, ESN is about 70% complete, with capabilities like control-room integration and air-to-ground communications being demonstrated, Rycroft said. However, considerable work remains before the ESN will be complete, he said.

“I wouldn’t want to pretend that we’re nearly there; we’re not,” Rycroft said. “That’s why my letter was very clear that this is going to go on until the end of 2026. But we are making progress, and we will keep you updated.”

As a point of comparison, AT&T’s initial five-year buildout of the FirstNet public-safety LTE network in the U.S. is expected to be completed on schedule in March 2023 and required only $7 billion in federal funding from spectrum-auction proceeds to get started. as well as 20 MHz of 700 MHz spectrum known as Band 14. On a square-mileage basis, FirstNet’s Band 14 coverage already is more than 20 times the geographic size of the UK, which is slightly smaller than the state of Michigan, albeit it much more densely populated.

FirstNet supports 2.2 million public-safety connections and is fully self-funded into 2042, with the FirstNet Authority expected to have about $15 billion in discretionary funds to enhance the network during the next two decades from its agreement with AT&T leverage the Band 14 MHz spectrum.
