Subject OOBE limits of 6 GHz VLP WAS/RLANs below 5935 MHz
Related WI SE45_05
Scope To further study OOB emissions from Very Low Power (VLP) WAS/RLAN devices operating in the band 5945–6425 MHz to protect CBTC systems that operate in the band 5915-5935 MHz

Comments This further study should investigate interference scenarios from Very Low Power (VLP) WAS/RLAN 6 GHz devices to CBTC. It could address the different types of CBTC networks that are currently operated across the band 5915–5935 MHz as well as possible future CBTC systems.
The initial work should focus on the definition of agreed procedures and assumptions for field measurements as well as their specifications and planning. This could be complemented by further studies taking into account the results of measurements, the transmission patterns of VLP devices (e.g. activity factors, mitigation techniques), CBTC network planning, and the combined impact with respect to sharing and OOB emission levels.
This work will need to be closely supervised by administrations sponsoring the measurement campaigns and should involve witness testing by representatives from CBTC and WAS/RLAN industry.
Note: ECC regulatory framework for WAS/RLAN OOB emission limit below 5935 MHz needs to be completed by 31st December 2024.
