RTLS WITH DASH7

1. DASH7 RTLS Tag stops at new location

2. Location sequence with nearby markers

Save power and spectrum by talking only when stopping at a new location

3. Location vectors sent to central system

Location Marker(fixed tag)

RTLS Tag(moving tag)

Gateway(fixed or mobile reader)




AIR CARGO WITH DASH7

•Savi DASH7 tags approved for use on all major, US commercial carriers.

•DASH7 tags never transmit unless requested by a reader.




CELL PHONES WITH DASH7

DASH7 is optimal in cellular phones as a wireless sensor communication link, where Bluetooth is too limited.

• Ultra low power: no impact on battery life.

• 433 MHz does not interfere with any technologies on the phone.

• No size impact: DASH7 technology can use the same silicon and antenna as NFC, or it can be put entirely in the SIM card.
