Public Safety Blog Series: Future Proofing Your In-Building Public Safety Coverage and Access Solution

September 3, 2015

With the increase of security threats and demands for greater efficiency and cross-agency interoperability, it is vital that first responders and emergency services personnel receive clear, secure, uninterrupted communications – critical during emergency situations.

Currently, first responders and emergency personnel are primarily communicating via voice through a two-way radio. In today’s public safety networks, various technologies are used for mission critical voice communications, with the most common being P25 Phase I and II in North America and TETRA, internationally. The most commonly used infrastructure that ensures first responders have coverage and access at all times even in areas such as the stairwells and backrooms are 1) repeaters, 2) analog DAS and 3) digital DAS.

Public safety requirements are evolving with improved methods in which emergency personnel communicate. Being able to transmit high-resolution imagery or real-time video footage would bring improvements in efficiencies and response time to further enhance the methods and ways to protect the public. For instance, those in support rooms who receive the real-time multimedia footage from front-line personnel would have more insight into what necessary steps should be taken to provide more timely and appropriate support.

On the commercial cellular networks side, the public has enjoyed enhanced data services through the next generation 4G LTE mobile services. Therefore, government agencies are beginning to embrace 4G LTE as the future standard for public safety with the benefits of shared multimedia between emergency personnel become more evident.

Even with the emergence of broadband data requirements, it will take some time before the broadband data services are standardized and become widely adopted. Government bodies and local ordinances have strict requirements, and standardizing the public safety communication network on 4G LTE will be a tremendous task.

Therefore, in light of economic pressures, enterprises must find a technology platform that not only serve their current requirements such as P25 Phase I and II and Tetra, but can easily migrate to higher speed network technologies, like 4G LTE, as required. This way, first responders and security personnel can have seamless public safety connectivity now.  With that, many have turn to digital DAS because of its scalable and future-proof nature, like the case of Dallas Fort Worth Airport.
