Cellular Optimization Market Needs

Market Background:

• 1 Billion potential cellular subscribers in the GSM rural areas

• Cellular backhaul relies on leased lines, private networks and satellite connections

• Backhaul costs reach 40-60% of the operators’ OpEx

• 2.5G / 3G services and mobile users’ increase generate additional network investments (Optimized 2G leased lines can be transferred to 3G networks)

-> Connectivity optimization seriously impacts costs reduction.


GSM Abis Optimization

Where Does it Apply ?

• GSM operators with expensive leased lines / satellite lines(> $500 / month / E1)

• GSM operators with a lack of bandwidth

• Due to lack of GSM infrastructure or

• Due to 3G service penetration

Abis Optimization – Features

• Up to 3:1 average GSM Abis optimization for E1 traffic

over E1 or ETH uplink

• DTX independent – optimization in non-DTX mode

• Improved optimization – Smart Packet Drop of non essential voice frames w/o affecting the voice quality and MOS

• Data Optimization adds ~5%-10% bandwidth savings

• High precision clock recovery over ETH uplink (no GPS required)

• Dynamic EDGE

• Auto timeslot detection for all cellular vendors

• Reduced end to end delay for data (25 ms)

• QoS - Signaling, voice and data separation at the uplink – each one could be assigned to a different priority queue

• FR, EFR, HR, AMR, HR-AMR codec support

Voice Trunking

The Vmux voice trunking family:

• Enables up to 16:1 compression of E1/T1, and analog lines

• Transmits the traffic over a single E1/T1, Serial, or IP link

Introducing the New MSS Topology

• This solution enables the operator to avoid 2G MSC forklifts in order to support 3G services

• Leverage the existing backbone segments while introducing NG-MSC switches

• Signaling compatible with NG-MSC and softswitches
