We are looking for a new PCB designed for us that meets the DASH7 ISO 18000-7 standard.
DASH7 is a recently ratified wireless active RFID standard originally intended for asset tracking. It has the following characteristics:
Operation at 433 MHz, globally available, unlicensed spectrum
Based on ISO 18000-7 standard
Multi-year battery life
Range of up to 2 km (potentially farther)
Penetration of concrete walls, water, and ability to "bend" around metal objects
Low latency protocol that enables reliable tracking of moving objects
Small, lightweight protocol stack that minimizes silicon costs
Data transfer at up to [url removed, login to view] (potentially as high as 250kpbs)
Sensor & security support
DASH7 provides an ultra low power active RFID for asset tracking with very long range due its operation at 433 MHz.
More detailed data can be found at www.dash7.org.
I will provide a copy of the DASH7 Mode 2 specification upon request.
