当レポートでは、エコシステムを構成する主要企業の代表者へのインタビューに基づき、公衆安全 (パブリックセーフティ) 市場におけるLTEの導入を促進・阻害する主な課題について分析し、P25 や TETRA といった既存の公衆安全技術とLTEの性能・コスト比較について議論しています。
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).
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.
