Standards based technology offers advantages and safeguards that proprietary technology cannot match. Standardization translates into a technology that has the support from its entire industry eco-system– it ensures interoperability and long term viability, and thereby contributes greatly to customers' confidence. Additionally, as it builds on research from multiple sources, standardization means technologies are continually improving performance-wise, and expanding into new areas and new applications.
The IEEE802.15.4a standard allows data rates up to 27 Mbit/s in a range up to 50 meters NLOS and a RTLS accuracy about +/- 10 cm.
DecaWave Technology is based on the IEEE802.15.4a standard.
IEEE802.15.4a Standard
IEEE802.15.4a is the new alternate PHY for the IEEE802.15.4 standard. It provides communications and high precision ranging / location capability, high aggregate throughput, and ultra low power; in addition to adding scalability to data rates, longer range, and lower power consumption and cost. IEEE802.15.4a adds significantly to the 802.15.4 standard, which is the PHY and MAC specification for Zigbee devices. These additional capabilities over the existing 802.15.4 standard are expected to enable significant new applications and market opportunities.
