The RAN Optimizer transparently connects between the BTS/BSC and the transmission network facility, reducing the amount of backhaul bandwidth required to support mobile services over constrained links, such as satellite.

RAN Optimizer Features:

• Transparent GSM FR, EFR, HR and AMR codec optimization
• Supports any data services (GPRS, EDGE, V.110 Fax/Modem)
• IDLE and silence suppression
• HDLC signaling frame extraction and forwarding
• EDGE traffic compression
• Signaling/voice/data traffic prioritization
• Transparent support of CDMA-IS95 traffic
• 3G and CDMA-1X traffic optimization (ATM IDLE cells removal, cell packing, ATM header and payload compression)
• ATM and TDM Pseudowire over IP
• SS7 traffic forwarding and optimization (Ater links)
• End-to-end Abis link continuity check
• Dynamic Abis map interface auto-configuration
• Traffic prioritization and 3 level QoS
• TRX channels usage real-time monitoring

RAN Optimizer Benefits:

• Reduced OPEX / minimal CAPEX
