The system was used to provide broadband services to households and small businesses in Gleann Cholm Cille in Donegal, Ireland. The trial was conducted over the span of a four month period and concluded in early 2005. "After trialing Alvarion's WiMAX-ready system, we found its technology interesting as a natural extension to the wireless LAN hotspots we have deployed across Ireland to date," said Orlagh Nevin, Head of Business Services for O2 Ireland. "O2's approach is to ensure that we keep up to date with new and emerging technologies and by conducting trials such as the WiMAX trial in Gleann Cholm Cille, we get real information and feedback. Having conducted trials on a number of technologies, the results from the trial in Gleann Cholm Cille showed that WiMAX was a viable solution for delivering broadband services to the rural areas of Ireland." With this BreezeMAX trial, Gleann Cholm Cille in Donegal joined selected European locations as pioneers in experiencing first-hand the benefits of WiMAX's quality of service (QoS), wide coverage and next generation non-line-of-sight (NLOS) performance. The Gleann Cholm Cille valley was selected as the location due to its challenging terrain and substantial distance from the nearest high-capacity network. BreezeMAX systems are operational in other Western European countries, including France and Spain. "BreezeMAX's non-line-of-sight capabilities facilitate almost universal accessibility to customers in a large base station area, making it an efficient and cost effective technology to roll out," commented Brendan Martin, Sales Manager of Siemens. "It is exciting to take a major role in the trials and eventual deployments of WiMAX technology across Europe." BreezeMAX is a third-generation OFDM platform with advanced NLOS functionality and is designed for operators to offer broadband IP-based voice and data services. In addition, it enables carriers to evolve their networks to industry standard solutions with 4 all the benefits of vendor interoperability. Its carrier-class design supports high QoS and broadband speeds to enable carriers to offer both data and toll-quality voice to thousands of subscribers in a single cell. "As expected, responses have been positive regarding the technology, and especially optimistic about the business case and overall service provisioning," said Zvi Slonimsky, CEO of Alvarion. "Deployment of BreezeMAX systems for fixed broadband access today speaks well to Alvarion's clear roadmap and vision. There is no doubt that WiMAX is the future for providing broadband in many areas in Ireland and throughout the world."
