Market Opportunity

The enterprise market has long been the most coveted segment of the wireless market because it combines high average revenue per user (ARPU) with low churn. While mobile voice service has become an invaluable tool to increase productivity in the enterprise market, services providers are continually challenged to develop new application-driven services that allow them to penetrate deeper into this high-value customer base.

Providing anytime, anywhere secure broadband access to laptop-carrying mobile workers is the single largest opportunity in the enterprise market today. Enhanced mobile voice services also represent a tremendous market opportunity in the enterprise environment.  A market opportunity exists for operators that can offer Push-to-Talk along with a wide range of other enhanced voice services, on a single network..

EV-DO Solution

Armed with a laptop and a CDMA 2000 EV-DO PCMCIA card, mobile professionals can access the Internet wherever the service is available and achieve DSL-like connectivity. They can also launch a VPN client with a secure tunnel into the corporate network, checking emails and browsing the corporate intranet with average speeds between 300 and 800 kbps and with a burst rate that exceeds 3 Mbps. Unlike public Wi-Fi or Ethernet connections, an EV-DO connection is secure and available anytime, anywhere.

The current generation of EV-DO, known as 1xEV-DO Rev A, is capable of supporting Voice over IP (VoIP).  An operator can use VoIP to launch serveral enhanced voice services for the enterprise:

• Push-to-Talk:  Push-to-talk (PTT) is a well understood application with a proven business case in several verticals such as the construction industry.  EV-DO Rev A enables PTT performance comparable to that provided by iDEN, a proprietary technology specially tuned for P2T.  With 1xEV-DO Rev A, CDMB operators have the ability of offer a competitive offering in this market.
  
  
• 3G-WiFi Integration:  Several enterprises have built extensive private Wi-Fi networks and are expected to demand devices and services that support voice on both the cellular and the Wi-Fi networks.  Rather than converging circuit cellular voice with VoIP over Wi-Fi, operators can offer a better solution to enterprises by supporting a single VoIP service on both access technologies.

Airvana’s IP-RAN Advantage

Airvana’s innovative IP-RAN network architecture optimizes the performance of the network, allows the network to scale seamlessly and reduces operating costs by offering service providers the flexibility to choose the lowest cost backhaul transport options. An IP-RAN network architecture creates an effective foundation for delivering real-time services like Voice over IP (VoIP) and Push-to-Talk. With an IP-RAN network 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.
