2. Introduction

3. References in Egypt Oil & Gas Sector –One base station and 3 Subscriber Unit –DATA Network Development Over water. –20 Base Station, 8 PTP link, 23 Subscriber Unit Survillance System – 2 Base Station, 25 Subscriber Unit – PTP LINK

4. Broadband Technology Broadband Technology is depend on IEEE 802.16 IEEE 802.16 is the new standard for broadband wireless access: –True broadband access (>10 Mbps) –High spectral efficiency –Optimized access with burst mode. –Robust wireless link with link adaptation and diversity –IP architecture with guaranteed Quality of Service

5. Broadband Solutions A WiMAX-class wireless broadband delivery platform Low Total Cost of Ownership and high scalability True broadband access (20 Mb/s on a 6 MHz channel) High Capacity - 84 Mb/s & more than 1,500 users per base station Bandwidth on demand with guaranteed service classes Robust Wireless link with OLoS & NLoS coverage Optimized for easy installation IP based with QoS for multiservice and SLAs Backhaul 10 - 100 Mbps Schools, administrations SMEs SOHOs Residential Hot spot backhaul InternetPSTN

6. Survillance Deployment Deploy Point to Multipoint broadband Network 2 Base Station 25 Subscriber nLOS, OLOS and LOS locations 14 Mbps Actual Throughput per base station. 25 Camera and IP Encoder Orthogon PTP LINK 99.999 % Reliability

8. Innovative Technology RapidBurst ® OptimaLink ® ServiceQ ® burst mode, on-demand bandwidth allocation dynamic optimization of each subscriber connection carrier-class multi-service QoS Service Intelligent Architecture

9. ServiceQ Carrier-Class Multi-Service QoS –Constant Bit Rate (CBR) Service Voice, video, low latency, low jitter –Committed Information Rate (CIR) Service Min rate guarantee; peak rate regulation –Best Effort (BE) Service Peak rate regulation Multiple Flows (up to 16) per Subscriber Classifiers at L2, L3 and L4 How to deliver GUARANTEED and tiered Quality of Service? Applying a Guaranteed Bandwidth and Quality of Services for each CPE

10. RapidBurst RapidBurst is: –Burst mode TDMA scheme –Flexible duplexing –Bandwidth on demand –High spectral efficiency –All the hooks for a wireless robust link and tiered QoS How to deliver bursty traffic with guaranteed Quality of Service and robust link? Dividing the bandwidth to 70% upstream and 30 % which guaranteed 1 Mbps per each CPE

11. OptimaLink Robust Wireless link: –Interference resilience –Obstructed Line of Sight/Near Line of Sight –Maximum bandwidth for each subscriber Dynamic per-subscriber link parameter optimization: –Power, modulation, coding, antenna diversity, frame size, etc. –Protection and redundancy provided on an as-needed basis guaranteed LOS, nLOS and OLOS Optimize Work over water

12. Diversity The Radio contains multiple transmitters, receivers and antennas Multiple images of the same data are transmitted across the link. The images are formatted in such a way that they are de-correlated; i.e. they will behave differently as the go around the obstacle. guaranteed link Reliability

13. Frequency Selection Robust when Interference is present: –6 MHz channel –ISM Band for 20 Channels. –Continuously monitors all channels –Automatically moves to cleanest channel –Avoids Interference –Allows for Co-Existence with other products Avoid Frequency Interference
