Broadband Wireless Access Across Holland
Top-tier Dutch wireline operator leverages carrier-class wireless to expand
reach, speed, scalability, robustness and QoS

Milpitas, Calif. and Rotterdam, Holland. October 26, 2004 - Enertel, one of Holland's largest data and telecom operators for the business market, and the country's largest wholesale provider to independent Dutch ISPs, has launched a national rollout of business-class broadband wireless access (BWA) services. This service is now available in Rotterdam and will be extended to Amsterdam, the Hague, Utrecht and Eindhoven before the end of this year. By the end of 2005 the network will offer national coverage. Enertel's wireless network is being exclusively deployed using Aperto Networks' 3.5 GHz WiMAX-class PacketWave^® systems. Enertel's first BWA customer is RoutIT, a Rotterdam-based supplier of network services to ICT resellers across the Netherlands.

"Aperto's PacketWave has been thoroughly proven as the business carrier's wireless broadband system of choice, and gives us unparalleled reach, speed of deployment, business-grade capacity and Quality of Service (QoS)," said Cees Meeuwis, CEO of Enertel. "We chose Aperto Networks because of these capabilities, and because of PacketWave's full WiMAX-class functionality. The company is leading the market in meeting all critical 802.16 carrier-class requirements."

Formed as the combination of nine cable and energy companies in 1994, Enertel successfully leveraged the Dutch telecom market deregulation to bring telephony and wireline access services to individuals and ventures across the Netherlands. It serves the entire Dutch data and telecommunications business market with innovative services in VoIP, IP VPNs, E-1 connectivity and wholesale services, both wireless and wireline.

"Enertel is a one of Europe's new leaders in broadband services. Through its Aperto-powered network, Enertel can now deliver carrier-class robustness, scalability and QoS in all of its business services, to Holland's top metros," emphasized Aperto CEO and Chairman Reza Ahy. "This new wireless network will also efficiently backhaul Enertel's WinQ HotSpot traffic, and extend capacity and coverage for its ISP customers. These performance advantages will further extend Enertel's market share leadership in wholesale services, and rapidly build subscriber volume on its WiMAX-class network."
