Airvana First in Industry to Demonstrate QoS-Enabled VoIP Over Commercial RAN
"We are pleased to have reached this significant industry milestone," said Vedat Eyuboglu, CTO of Airvana. "VoIP is a highly delay-sensitive application, and delivering VoIP over an IP-based wireless infrastructure requires sophisticated QoS techniques. Our demonstration of VoIP on Airvana's QoS-enabled commercial EV-DO Rev. A network infrastructure is a significant step towards commercial VoIP services over EV-DO Rev. A."
Specifically, Airvana made mobile-to-mobile VoIP calls using handsets based on QUALCOMM's MSM6800 baseband ASIC and software to establish QoS-based calls over delay-sensitive/low-latency flows in a commercial-grade Rev. A network. EV-DO Rev. A supports multiple QoS flows per handset each with its own unique QoS requirements. This capability allows VoIP and other multimedia traffic to receive higher priority over other best-effort traffic, such as web, email, and file transfer traffic.
"QUALCOMM is pleased to see Airvana's VoIP Lab succeed in this critical demonstration," said Roberto Padovani, CTO for QUALCOMM. "Rev. A promises to deliver a new breed of performance on CDMA2000 networks, and the VoIP Lab serves as a viable proving ground for operators preparing for Rev. A upgrades."
