サマリー

米国調査会社ヘビーリーディング社の調査レポート「公共安全のLTE:当てにしてはいけない」は、公共安全市場のLTE採用の促進要因と阻害要因に関する重要事項を分析している。従来の公共安全技術であるP25やTETRAなどとLTEの性能やコストについて比較している。この調査レポートは、Athena Wireless、シスコ、Ethertronics、Harris、ノキア、Sonim Technologies、TeleCommunication Systems (TCS)などの代表的な関連企業に対するインタビューに基づいている。

Every industry that uses a proprietary wide-area wireless technology eventually must decide whether to switch to cellular. Public safety is no exception, but it's making the transition in fits and starts, and the end result likely will be more expensive and less comprehensive than anyone involved would like.

This transition is underway in many countries throughout the world, but arguably the most ambitious project is the U.S. First Responder Network Authority (FirstNet), which operates within the National Telecommunications and Information Administration (NTIA) agency. The Middle Class Tax Relief and Job Creation Act of 2012 created FirstNet, whose role is to enable a "nationwide, high-speed, broadband network dedicated to public safety," with Long Term Evolution (LTE) as the foundation.

Regardless of how it's implemented, LTE will gradually shift the mix of public-safety devices away from purpose-built land-mobile radios (LMRs) and toward smartphones, tablets, portable routers and other devices adapted from the consumer and business markets. This trend will create opportunities for vendors that sell device-security and -management products for the enterprise market because those solutions will be needed in the public-safety sector, too.

LTE also is an emerging option for drone communications. One reason is because it's a fat pipe, so it's capable of supporting HD video. Another reason is because it has a longer range than the wireless technologies currently used, so it enables public-safety applications where it's dangerous or not practical for the pilot to be close to the site under surveillance.

Even when major initiatives like FirstNet are complete, there will still be situations where LTE service is poor or unavailable. One example is when a disaster takes out a portion of the network; another example is a remote area where the economics don't justify building a commercial or private network in the first place.

LTE's prioritization and QoS features make commercial networks better able to meet public safety's unique requirements. These features, along with the cost of building and operating public-safety-only networks, make it likely that FirstNet and similar initiatives will be the exception rather than the norm.

LTE for Public Safety: Don’t Count on It identifies and analyzes these and other key issues driving and inhibiting the public-safety market's adoption of LTE. It discusses how LTE compares to incumbent public-safety technologies, such as P25 and TETRA, in terms of performance and cost. The report is based on interviews with a representative sample of companies in the ecosystem, including Athena Wireless, Cisco, Ethertronics, Harris, Nokia, Sonim Technologies and TeleCommunication Systems (TCS).

Sample research data from the report is shown in the excerpts below:

  • Many public-safety agencies around the world already use commercial cellular networks to one extent or another. That usage will continue as those agencies migrate to LTE, but in a minority of cases, agencies will own and operate LTE networks. FirstNet is one example, but the common denominator is that these agencies believe ownership is the only way to ensure that the network will be there and theirs when it's needed. The following excerpt lists major examples of municipalities that are moving ahead with their own LTE networks.

Public Safety's Long-Term Evolution

 

Heavy Lifting Analyst Notes
Tim Kridel

4/10/2015

By 2020, 63% of the world's population will be covered by LTE, and more than 30% of connections will use the technology, the GSMA predicts. There's safety in those numbers -- literally.

Public-safety agencies worldwide have begun migrating away from proprietary mobile technologies, such as Terrestrial Trunked Radio/Trans-European Trunked Radio (TETRA) and P25, in favor of LTE. They aren't the only ones migrating to LTE, and that's a major reason for public safety's move: LTE offers an enormous vendor ecosystem and global cost structure precisely because so many other verticals are using it. Public safety benefits from scales of innovation and economy that it alone couldn't enable.

But as discussed in the new Heavy Reading 4G/LTE Insider, "LTE for Public Safety: Don't Count on It," achieving those benefits will take time and money. A prime example is the US FirstNet network. Congress earmarked about $7 billion of spectrum auction proceeds for FirstNet, but that won't be enough to achieve its goal of a network spanning all 50 states, the District of Columbia and five territories. "It's a huge delta between what the expectation levels are of the public-safety community and the money they have," one vendor says.

To shrink that delta, public safety will have to take a big-tent approach. One likely way is by accepting the overtures of utility companies, which argue that they should have access to public-safety networks, spectrum or both because they provide a vital service. In exchange for access, they would help support those networks. Possibilities include funding and/or providing access to infrastructure that could support basestation equipment.

"Utilities are perfect," says Sanjay Jahwar, Sonim Technologies VP and general manager of solutions, marketing and business development. "They have a lot of money. They have a lot of vertical assets they can share. They have a lot of backhaul they can share."

Another likely partner is mobile operators, many of whom covet FirstNet's 700MHz beachfront spectrum. The big wild card is whether operators and FirstNet can develop a model that enables sharing in a way that operators and their customers don't find onerous. After all, in the wake of a hurricane, terrorist attack or other major disaster, people want to be able to use their mobile phone to get help and get information. Previous attempts at sharing suggest that FirstNet faces challenges in hammering out an agreement that everyone can live with.

Another option is for public-safety agencies to increase their use of commercial cellular networks, especially when LTE reaches the point that it covers 63% of the world's population. In some countries, that could be the primary way their agencies use LTE. In others, such as the US, commercial cellular could be a major adjunct. "We think the early part of this market will be devices that work on commercial carrier networks, are often sold by the public-safety sales teams of those carriers and are FirstNet-ready, [meaning] they can roam onto a Band 14 network," one vendor executive says.

The bottom line is that LTE is a good fit for public safety in terms of cost structure, innovation and capabilities. Implementing it is the big challenge.
