EDX Wireless, a global leader in WiMAX and OFDM-based network planning tools, announces that OTE Hellenic Telecommunications Organization S.A., Greece’s leading telecommunications provider, uses EDX’s carrier-class wireless network planning tool to design its 3.5 GHz WiMAX pilot networks. OTE is testing a wide range of value-added, high bandwidth data communications services over WiMAX to be offered to consumers and enterprises nationwide.
OTE has already begun deployment on a nationwide network with initial projects that target pilot markets in Attica and Mount Athos. These pilot markets, being used to evaluate the technology for the nationwide rollout, include approximately 20 access sectors and 200 subscriber units. Designs that include the consideration of 3D vector building databases will be part of the detailed studies used for the evaluation. EDX SignalPro with the Network Design Module was used for these initial network designs and will continue to be used throughout the rest of the deployment and optimisation phases.

“OTE has a long history of success with designing their array of wireless networks using EDX tools. As they’ve moved forward in WiMAX, their decisions to use EDX planning tools have been solidified, proving the flexibility found with EDX,” said Bob Shaw, Vice President of Sales and Marketing for EDX. “OTE is using the most powerful tool available to advance their WiMAX plans. They now have the ability to plan for and carefully manage the considerations of today’s broadband networks, including interference-sensitive advancements such as MIMO and adaptive modulation, as well as perform sophisticated system capacity analysis that accounts for multiple user profiles.”

OTE has used EDX’s planning tools since 1995, with several EDX SignalPro licenses and a varied selection of add-on modules. Using EDX’s flexible network planning tools, OTE has planned their paging system, point-to-point microwave networks, point-to-multipoint networks and the commercial TETRA system, which was heavily used during the 2004 Olympic Games in Athens.

The OTE and EDX relationship has been managed by EDX’s longtime Greek distributor, Heletel S.A., which also supplies supporting 3D building databases, technical support and training.
