omlox core zone specification: V1 vs. V2

What's new?

Unlike omlox Core Zone Version 1 specification, omlox Core Zone Version 2 specification is using the latest UWB standard IEEE 802.15.4z which promises an excellent UWB IC availability from various vendors at reasonable costs.

Further benefits included in omlox Version 2 are:

  • Higher performance, increase in scalability and global regulatory compliance
  • The additional Uplink-Time Difference of Arrival (UL- TDoA) mode now enables the usage of cost-efficient tags with a long battery runtime
  • Increased location bandwidth allows more tags to be localized simultaneously
  • The new Out of Band (OoB) communication is independent from Bluetooth Low Energy (BLE) and therefore not in conflict with customer devices, allowing an independent usage and a good scalability as needed for professional applications
  • As an alternative to UWB channel #3 in the lower bands, omlox Core Zone Version 2 now also features the usage of UWB channel #9 (~8 GHz), allowing global coverage as this is currently the only channel which can be used worldwide without any local restrictions
