Cloud Based Global Communications for SAR Teams

Datalink's cloud can link volunteer SAR teams together using automatic geo-zoning to exchange text messages and GPS locations. Teams would continue to use their UHF/VHF radios between their own team members. Base or mobile command station using Datalink's WebGate can see GPS locations and exchange text messages with other teams.
3rd party satellite uplinks can be connected to Datalink's cloud DataGate allowing for voice and data communications with other agencies on a global basis as needed.
In locations where cellular 4G coverage is available, the Datalink smartphone application will link directly to the cloud DataGate control hub.

Portable UHF/VHF radios with GPS can link to a command vehicle equipped with a DataGate and satellite uplink allowing all members to be tracked by GPS for safety.

The NAL SHOUT ns is ideal for search and rescue personnel. Very light and small, it can be worn on the body and links Iridium satellites to smartphones over Bluetooth. This allows for GPS tracking and two-way text messages.

The SHOUT ns can also operate with a CR123 non-rechargeable battery. The ns supports transmission of free-text, canned messages, and a combination of free-text and canned messages via a smart phone. The device can periodically wake up from sleep to send its position report to a command center.

The Flaw with All VHF/UHF Radio Networks

When volunteer SAR teams from other regions join forces to respond to a major incident, each group usually bring their own portable radios. The radios are on their own assigned frequency channels which typically do not link to other groups' portable radios. This is a global problem and reliable communications between groups is critical.

Move Over to 4G Wide Area Networking

Datalink's SARNet with global network agnostic SIMs can deliver a common communications platform for any location. Add Vocalis PoC for voice communications.

PoC (PTT over Cellular)

Datalink and its global partners can provide Vocalis PoC service in most countries with 4G cellular networks. Team members talk instantly between groups or one to one with no distance limitations. Most PTToC smartphones display where assets are on a map.

Datalink's TrakLink Android application allows members to touch the red panel for three seconds to send an immediate alert when in distress. This alert is relayed to all team members and over the cloud network to the remote command center.

Worn by team member the goTennaMesh provides a GPS location of each member when polled or when an SOS is activated by a team member. The device uses an internal 900Mhz spread  spectrum transceiver with automatic mesh relaying and connects to an Android smartphone. Datalink's TrakLink relays the SOS and text messages over 4G, Iridium GO (satellite), or NAL SHOUT ns (satellite).

goTenna DataNET GPS
Available to Volunteer Groups Only

Datalink's DataNET version of the goTenna provides GPS and SOS protection for SAR personnel with goTenna's automatic relay to provide wide range tracking using a common UHF channel.

Datalink's custom application installed on any Android smartphone controls the goTenna and allows for SOS and GPS tracking only. Alternatively the goTenna sends GPS location updates every minute from every goTenna on the DataNET. Two-way text messaging is also a built-in feature.

A WebGate installed in the mobile command vehicle process all data with all SAR team member's locations appearing on map screens.

Data can also be routed from mobile command vehicles to the DataGate cloud over 4G, Iridium GO, or other satellite modems.
