Automating UMTS Optimization.
Schema`s approach to UMTS optimization eliminates tedious trial and error processes by automating the fine-tuning of vital network parameters. Integrating advanced automated cell parameter planning techniques increases capacity and coverage, in addition to ensuring a smooth migration to new technologies. This white paper, originally published for the UMTS 2001 Expo, explains the advantage of Schema`s automated cell planning technology over the traditional solutions available today.
