We are capable of measuring up to 300 real UEs. Using 300 real UEs with a combination of load simulator provides a realistic representation of actual user behaviour.
Our comprehensive testing covers scenarios like capacity, throughput, mobility and quality of experience ensures a thorough evaluation of the PTT solution’s performance under various load conditions.
Realistic traffic mix will be agreed after having discussion with the key stakeholders that reflects the actual distribution of PTT call, data, voice and video call.
