Schema's UMTS OptiPlanner set to ease migration and help
operators maximize return on investment in Third-Generation Networks



London - October 17, 2001 - Schema, the leading provider of network planning and optimisation solutions for GSM and GPRS networks, today announces the launch of its UMTS OptiPlanner network planning product. This new product is part of a complete network optimisation solution that offers operators a comprehensive solution for planning 3G networks, enabling successful migration and subsequent revenue generation.

Operators in Europe are faced with running hybrid networks consisting of GSM, GPRS and UMTS elements as they migrate to new technologies. Schema's UMTS OptiPlanner enables the automatic optimisation of the RF environment to enable unparalleled performance by influencing system-wide parameters, such as antenna configuration and transition levels. Operators moving from GSM can exploit it at both the initial green-field planning and migration stages of the network.

The UMTS OptiPlanner is the latest addition to Schema's Telecom Resource Management (TRM) product suite. These products focus on complete network optimisation for GSM/GPRS/UMTS networks, including both OFP (optimised frequency planning) and automatic cell parameter planning.

Schema's products for wireless networks are powered by proprietary optimisation technology - evolutionary algorithms that imitate nature's trial-and-error problem solving methods - and mathematical modelling to create a simulation of the physical network.

Dr. Yosi Ben-Dov, CEO of Schema, said: "This latest addition to our TRM family of products is a natural extension to our field-proven GSM/GPRS optimisation solutions. We are challenging the conventional, tedious approach of looking at the network on a per antenna basis - instead we provide operators with an entire 'forest' of sites and antennas to be planned and optimised simultaneously. This system-wide approach ensures we produce the most comprehensive simulation results and, thereafter, system performance."



"Operators have invested vast sums in 3G networks and now it is imperative that they maximise those assets - servicing as many users as possible per cell" continued Ben-Dov. "They must be able to cost-effectively deploy networks with sufficient coverage, quality and capacity to attract large numbers of customers in a difficult business climate.

"UMTS operators do not enjoy the benefits of earlier generation GSM-900 and DCS-1800 systems build-outs, where easy access to funding and pent-up demand for service made capital efficiency less of a priority than time to market. With greater economic constraints, 3G system planners need to pay more attention to engineering detail in an effort to optimise their networks first time round.

"Our technology offers a breakthrough - applying powerful mathematical modelling offering unprecedented accuracy, and evolutionary algorithms capable of finding the very best management solution in extraordinarily complex systems."

The UMTS OptiPlanner is a tried and tested solution. Schema has used the UMTS OptiPlanner in Israel to provide PCL (Pelephone Communications Ltd.) with the UMTS radio planning needed for the preparation of its response to the Ministry of Communications 3G license bid.

About TRM

Schema's TRM product suite provides operators with complete network optimisation and management solutions. 3G networks will consist of the delivery of multimedia services over transparent, flexible networks, supported by the current 2G networks. This means engineers will need to effectively bridge three technologies (GSM, GPRS and UMTS). In addition, operators need to implement 3G in as short a time frame as necessary in order to deploy revenue-generating 3G operations. Schema's solutions provide the necessary structure to ensure seamless and rapid migration.





The TRM product family comprises:


· Falcom (spectrum optimisation system)

· GPRS Optimiser

· UMTS OptiPlanner
