The following service providers operate a mobile consumer service using a 1xEV-DO solution from Airvana or its partners.
The mobile operator environment around the world has become increasingly competitive supporting more than 2 billion subscribers. As voice revenues per user continue to fall, operators are now seeing rapid growth in data ARPU from a variety of data services. With texting, messaging, ringtones and gaming driving the majority of initial demand, operators are now capitalizing on their investments in mobile broadband 3G networks to deliver rich multimedia services like music, video, push email, full HTML web surfing, Push-to-Talk, VoIP, IP-TV, etc.
EV-DO Rev A is a leading 3G mobile broadband technology with commercial availability offering 3.1Mbps peak downlink data rates and 1.8 Mbps on the uplink.
Commercial networks based on EV-DO were first launched in 2002, and today in early 2007, there are more than 120 commercial networks around the world providing service to more than 65 Million subscribers.
Airvana’s innovative IP-RAN architecture optimizes the performance of the network, allows the network to scale seamlessly and reduces operating costs by offering the service providers the flexibility to choose the lowest cost backhaul transport options. An IP-RAN architecture creates an effective foundation for delivering real-time services like Voice over IP (VoIP) and push-to-talk. With an IP-RAN architecture, Quality of Service (QoS), an essential requirement for VoIP, is applied uniformly across the core network and the radio access network. Handoffs are faster and introduce no additional latency. Better QoS and lower latency translate into higher VoIP capacity.
