上个月,FCC委员批准了Anterix的建议,即重新配置窄带900mhz频谱,从而使Anterix将其该频段的许可证合并为一个3×3mhz带宽,可以支持由公用事业公司或其他关键基础设施实体构建的LTE宽带系统

摩托罗拉解决方案公司(Motorola Solutions)今天宣布了其关键基础设施专用宽带,该平台旨让公用事业公司、能源公司和其他关键基础设施实体利用不同的宽带和窄带系统,包括授权给Anterix的900mhz频谱上运行的专用LTE网络

上个月,FCC委员批准了Anterix的建议,即重新配置窄带900mhz频谱,从而使Anterix将其该频段的许可证合并为一个3×3mhz带宽,可以支持由公用事业公司或其他关键基础设施实体构建的LTE宽带系统

摩托罗拉解决方案公司全球企业部门副总裁斯科特·肖佩尔(Scott Schoepel)表示,FCC的900兆赫订单包括允许现场固定设备(如新的EDG 4200智能网关调制解调器)Anterix频谱上运行时,可以使用2瓦特(相当于普通LTE设备10倍)的功率传输数据包

Schoepel接受IWCE紧急通信部采访时说:“我们相信,通过EDG 4200产品和2瓦容量,我们可以复制LTE数据的LMR型覆盖范围。”。“从总体拥有成本的角度来看,这可以避免您不得不构建增量站点、回程、备用电源以及所有与构建塔式站点相关的功能

“利用现有的[LMR]占地面积,并真正能够提供类似的覆盖范围,我们认为这将为我们的客户节省大量的成本和部署时间。”

Schoepel说,900mhz宽带规则中另一个有趣的缺陷是FCC规则中“没有考虑到保护带”,尽管大多数分配给LTE的频谱都包括一个保护带,以减少潜有害干扰的可能性。他说,没有保护带可能会对摩托罗拉解决方案有利,摩托罗拉解决方案公司习惯于LMR领域开发不带保护带的解决方案

Schoepel说:“我们认为我们是唯一一家能够没有保护带的环境下提供射频规范的公司。”

“产品规格与我们的窄带传统,以及我们如何将其应用于宽带,以及我们宽带和窄带进行系统设计工作的能力,使这两种技术能够最小干扰或无干扰的情况下协同工作,我们认为这是摩托罗拉解决方案所独有的。”

当被问及摩托罗拉解决方案是否是唯一一家定位于新的900兆赫宽带频谱上提供高功率LTE解决方案的供应商时,Anterix向IWCE的紧急通信部门提供了Anterix战略开发副总裁Alice Moy Gonzalez的以下声明

Moy Gonzalez声明中称:“供应商对900 MHz FCC程序产生了广泛兴趣,并通过参与UBBA(公用事业宽带联盟)而进一步扩大。”。“LTE固有的好处是多方面的,供应商频段内部署的广泛选择只是其中之一。我们很高兴摩托罗拉将其创新解决方案引入这个不断增长的生态系统。”

Schoepel表示,EDG 4200的大功率版本产品目前正试用中,但预计将第三季度末商用

除了EDG 4200智能网关调制解调器产品系列之外,摩托罗拉解决方案公司的关键基础设施专用宽带产品还推出了另一个新产品组合,LXN 7900产品线。Schoepel说,LXN7900的产品组合包括一个LTE核心,作为一个本地或基于云的解决方案,以及LTE无线接入网络(RAN)eNodeB,通常位于塔台站点

Schoepel再次指出,摩托罗拉解决方案公司能够开发一个没有频谱保护带的情况下运行的LTE平台,对于那些寻求利用Anterix公司授权的900 MHz宽带频谱的实体来说,这一能力很有价值

Schoepel说:“我们已经有了一款产品,我们认为它不仅能达到高功率水平,而且还具有一些令人难以置信的射频规格,”他提到LXN 7900产品组合及其低邻道泄漏率,这证明了它控制带外发射的能力

“因此,与3GPP标准相比,该产品无疑将大大优于市场上的其他产品。我们认为非保护频段的情况下,这一点很重要,允许900 MHz LMR和900 MHz宽带共存。这对于实现[联邦通信委员会]报告和命令中概述的目标以及确保这些系统能够作为好邻居运行至关重要。”

Schoepel表示,新的摩托罗拉解决方案的关键基础设施专用宽带旨为网络运营商提供显著的灵活性,新平台能够通过其关键连接解决方案支持与现有P25或DMR网络的互操作性。摩托罗拉解决方案公司(Motorola Solutions)新推出的Nitro宽带数据服务整合了3.5GHz频段的CBRS频谱。Nitro生态系统还包括使用WAVE push-to-talk宽带技术的潜用途,这是一种使用Kodiak软件的功能,但摩托罗拉官员认为CBRS的私人宽带重点将放数据和视频应用上

Schoepel说,摩托罗拉解决方案公司的新宽带平台支持多种连接选项。除了900 MHz专用宽带和CBR外,该平台还支持通过Wi-Fi、窄带IoT(NB-IoT)进行连接,并通过FirstNet、AT&T和/或Verizon实现运营商连接

Schoepel说,EDG 4200“可以有多种不同的配置,提供多种SIM卡和多个收音机。”。“例如,您可以将900 MHz LTE和CBR配对。或者,你可以把900兆赫和一个载波[连接]配对

“因此,如果一家公司想从现开始部署一个载波,并接入该频谱后迁移到900兆赫,他们可以做到这一点。或者,您可以(以某种方式)部署载波,使其成为冗余的后备选项。”

Motorola Solutions today announced its Private Broadband for Critical Infrastructure, a platform designed to let utilities, energy companies and other critical-infrastructure entities leverage disparate broadband and narrowband systems, including private LTE networks operating on 900 MHz spectrum licensed to Anterix.

Last month, FCC commissioners approved the Anterix proposal to reconfigure narrowband 900 MHz spectrum in a manner that results in Anterix consolidating its licenses in the band into a 3×3 MHz swath that can support LTE broadband systems built by utilities or other critical-infrastructure entities.

Scott Schoepel, vice president of Motorola Solutions’ Global Enterprise unit, said the FCC’s 900 MHz order includes rules allowing fixed devices in the field, like the new EDG 4200 smart gateway modems, to transmit packets using 2 watts—10 times the power of normal LTE device—when operating on the Anterix spectrum.

“We really believe that— with the EDG 4200 products and that 2-watt capability —we can replicate LMR-type coverage for LTE data,” Schoepel said during an interview with . “From a total-cost-of-ownership [perspective], that prevents you from having to build incremental sites, backhaul, backup power and all of the things that go along with building tower sites.

“Leveraging that existing [LMR] footprint and really being able to provide that similar coverage, we think is a significant cost savings and time-to-deployment savings for our customers.”

Another interesting wrinkle in the 900 MHz broadband rules is that there is “no guard band contemplated” in the FCC rules, even though most spectrum allocated for LTE use includes a guard band to reduce the chance for potentially harmful interference, Schoepel said. The absence of a guard band could prove to be advantageous for Motorola Solutions, which is accustomed to developing solutions in the LMR arena that do not operate with a guard band, he said.

“We think we are the only ones who can provide the RF specifications to operate in the environment without the guard band,” Schoepel said.

“Between the product specs—with our narrowband heritage and how we apply that to broadband—and our ability to do system-design work in both broadband and narrowband—allowing these two to work together with minimal or no interference issues—we think is unique to Motorola Solutions.”

When asked whether Motorola Solutions is the lone vendor positioned to provide a high-power LTE solution on the new 900 MHz broadband spectrum, Anterix provided with the following statement from Alice Moy-Gonzalez, vice president of strategic development for Anterix.

“There has been broad vendor interest in the 900 MHz FCC proceeding, amplified through participation in UBBA [Utility Broadband Alliance],” according to the Moy-Gonzalez statement. “The benefits inherent in LTE are numerous, and the wide range of vendor choices for deployment in the band is just one of them. We are excited to have Motorola  bring their innovative solution into this growing ecosystem.”

Schoepel said the high-power version of the EDG 4200 products are being used in trials right now, but they are expected to be commercially available by the end of the third quarter.

In addition to the EDG 4200 Smart Gateway Modem product family, Motorola Solutions’ Private Broadband for Critical Infrastructure offering features another new portfolio, the LXN 7900 product line. Schoepel said the LXN 7900 portfolio includes an LTE core—available as an on-premise or cloud-based solution—and LTE radio access network (RAN) eNodeB that typically is located at tower sites.

Once again, Schoepel noted that Motorola Solutions’ ability to develop an LTE platform that operates without a spectral guard band is expected to be valuable to entities seeking to leverage the 900 MHz broadband spectrum licensed to Anterix.

“We’ve got a product that we’re building for that, that we think not only achieves the high power levels but really has some incredible RF specifications,” Schoepel said, referring to the LXN 7900 product portfolio and its low adjacent-channel leakage ratio, which is a testament to its ability to control out-of -band emissions.

“So, this product will be substantially superior to others in the market—certainly, as compared to the 3GPP standards. We think that’s important in a non-guard-band situation, to allow for this co-habitation of 900 MHz LMR and 900 MHz broadband. It will be critical to achieving the goal that the [FCC] outlined in the report and order and to ensure that those systems can operate as good neighbors.”

Schoepel said that the new Motorola Solutions’ Private Broadband for Critical Infrastructure is designed to provide significant flexibility to the network operator, with the new platform being able to support interoperability with existing P25 or DMR networks through its Critical Connect solution. Integration of Motorola Solutions’ new Nitro broadband data service that leverages CBRS spectrum in the 3.5 GHz band is also available. The Nitro ecosystem also include the potential use of WAVE push-to-talk-over-broadband technology—a capability that uses Kodiak software–but Motorola officials believe the CBRS private broadband focus will be on data and video applications.

Motorola Solutions’ new broadband platform supports a wide variety of connectivity options, Schoepel said. In addition to 900 MHz private broadband and CBRS, the platform enables connectivity via Wi-Fi, narrowband IoT (NB-IoT) and carrier connections via FirstNet, AT&T and/or Verizon.

The EDG 4200 “can come in a variety of different configurations—multiple SIM cards and multiple radios are available,” Schoepel said. “You can pair up 900 MHz LTE and CBRS, for example. Or, you could pair up 900 MHz and a carrier [connection].

“So, if a company wanted to start deploying a carrier today and migrate to 900 MHz when access to that spectrum is complete, they could do that. Or, you could deploy [in a manner that makes] a carrier a redundant fallback option.”
