TrellisWare’s MANET products serve a number of applications encountered by commercial and military customers. In addition to both Comms and Sensor network applications in the military, customers in industries such as emergency/disaster response, homeland security, mining, and industrial monitoring can utilize our MANET products. These applications are marked by wide variation in the number, density, and deployment range of the units. A few representative application scenarios are described below.
Application Scenario: Sparse Urban
Total Units: 4
Scenario: Using three parked cars and a unit in a mobile car, the TrellisWare radios were able to cover downtown San Diego. Along with using a minimal number of units, video was transmitted from a dash cam in the mobile car and all units were able to utilize the PTT feature to communicate. The green lines in the picture to the left show the coverage across downtown San Diego.
Application Scenario: Dense Urban
Total Units: 25
Scenario: Covering a large urban center is difficult. Add to that the ability to utilize PPT and transmit video while on the move. With three units transmitting video and using PTT while mobile, the urban area gets covered. The video was remote controlled using a satellite backhaul.
With one unit placed down at Torrey Pines state park taking a video of the ocean and beach below, one unit on the top of a local hilltop and a third on another hilltop we were able to transmit video 12 miles back to our headquarters. There was also a unit traveling at highway speeds with a dash cam sending video data back to our headquarters. The video was sent in conjunction with the use of voice to communicate between units. All units were tracked to show position locations at any given time.
Heavily Foliated Terrain
Units were carried by dismounted marines, who used the networked PTT voice, were tracked utilizing Position Location Information from the units and used IP data traffic with no failures. These units were operated over a five day day period across heavy vegetation.
Using four units on the interior of the ship and two to provide exterior coverage, an entire ship could be covered with PTT voice and streaming video with no loss and no leaky feeders. The crew was able to cover bow to aft and port to starboard sides as well as the engine room of the vessel.
