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

• Ultra low power: no impact on battery life.
DASH7 is optimal in cellular phones as a
• 433 MHz does not interfere with any
technologies on the phone.
wireless sensor communication link, where
Bluetooth is too limited. • No size impact: DASH7 technology can use
the same silicon and antenna as NFC, or it
can be put entirely in the SIM card.
