  2. Optimizing Network Performance • Optimization is applied at two levels: • Optimization at Network Element level (box solution). • Optimization at Network level (Network solution) Proprietary and Confidential - RadioTel Ltd. 2

  3. Optimizing Network Performance • Network Element’s parameters (box solution) • Spectrum Efficiency • Dynamic and Flexible capacity (bandwidth) • Cross-connect, Switching & routing functionality • Mixed traffic circuit switched & packet Proprietary and Confidential - RadioTel Ltd. 3

  4. Spectrum Efficiency Configurable modulation: QPSK up to QAM256 (or other modulation techniques i.e.: TCM, OFDM) via management station or automatic sensing Results: Improvement in spectrum efficiency: 2bits/Hz up to 8 bits/Hz Proprietary and Confidential - RadioTel Ltd. 4

  5. Configurable Modulation QPSK QAM256 QAM128 QAM16 QAM64 Proprietary and Confidential - RadioTel Ltd. 5

  6. Dynamic & flexible capacity • Flexible and configurable capacity of the element through the management station. • Mixed circuit switched & packet traffic in wireless constraint’s network requires dynamic sensing of overflow traffic. Proprietary and Confidential - RadioTel Ltd. 6

  7. Flexible Capacity 21 x E1/T1 4 x E1/T1 STM-1/OC-3 8 x E1/T1 16 x E1/T1 Proprietary and Confidential - RadioTel Ltd. 7
