By September 16th, 2017 the people on the island of Puerto Rico were aware of a large hurricane heading across the mid-Atlantic towards the Caribbean. No stranger to the destructive power of hurricanes, long-time residents still trembled at reports of ever-increasing winds and a track which, by the 18th, put their island in the crosshairs of the beast. Brave residents prepared as best they could for the hurricane, now named Maria, but no one was prepared for the overwhelming devastation when it smashed directly onto the island on September 20th. The island’s power grid was completely destroyed, leaving all 3.4 million residents in the dark.

Rescue and relief efforts were also set back by the loss of 85% percent of above-ground phone and internet cables and 95% of the island’s cell networks. The death toll from Maria is still a source of contention but it is certain that lives were saved thanks to FirstNet - the First Responder Network Authority. Established after 9/11 and Hurricane Katrina, FirstNet’s primary objective was to establish a nationwide, inter-service (police, fire, army, navy, etc.) wireless broadband network. This network would provide first responders a means of interfacing without relying on our typical communications infrastructure, one vulnerable to destruction.

FirstNet’s charter is “providing a single interoperable platform for law enforcement, firefighters, paramedics and other public safety officials in every state, county, locality and tribal area.”

In the future, Communications devices built for Mission Critical Communications for First Responders and FirstNet must not only operate reliably in all physical environments but also operate using proprietary communication standards established by each branch and public safety organization.

Leveraging its vast experience in RF and Microwave products, as well as being at the forefront of developing integrated, single-chip solutions for Software-Defined Radio, Analog Devices recently announced the ADRV9002, the world’s first narrow-to-wideband, integrated transceiver with digital integration. Together these three features provide a robust, agile platform for the development of First Responder compatible communications systems:

  • Narrow-to-wideband refers to the width of the transmitted signal. It can be narrow (so more voice and lower rate data protocols could be sent at the same time) or wide (for times when the mission required the transmission of video and other high data rate signals).
  • Integrated means many of the required supporting functions such as frequency synthesizers, clocks, power-supply monitors to improve consumption efficiency, digital pre-distortion to improve the efficiency and efficacy of the transmitter as well as other functions otherwise requiring time to design into a solution.
  • Digital integration provides developers of mission critical communications solutions the ability to program each service’s proprietary communication protocols into the ADRV9002.

 With an advanced set of tools, and with the ADRV9002 Evaluation Kit designers of communication solutions can move rapidly from evaluation to prototype. With the kit, developers can develop code compatible with their service’s systems, but at the same time provide the capability to build a true software defined radio to cut across all the different communications standards (police, fire, rescue, military, etc.) for mission-critical communication.
