Multiple Operational Modes for Increased Productivity

The Invex.NxG™ i.Classic™, i.Drive™, and i.PC™ can each be deployed in a variety of modes to achieve specific objectives.

• Network Optimization
• Network Benchmarking
• Network Integration
• Maintenance and Troubleshooting.

All Invex.NxG solutions feature a common engine that gathers data in a consistent format but is easily translated based on your need.  All modes support testing across a range of technologies including CDMA/ CDMA2000® 1X/1xEV-DO, IS-136, GSM/GPRS/EDGE, UMTS WCDMA, HSUPA, HSDPA and iDEN™.  So you can maintain, measure and optimize your network performance with one solution.

Optimization

Using Invex.NxG to optimize the network, the operator sees the network from the subscriber’s perspective. Using an actual subscriber handset or software-controlled test phone, the user can record and display detailed performance such as:

• Signal strength
• Bit or frame error rate
• Dropped calls
• Failed originations
• GPS location coordinates
• Layer-3 messages

When used as an optimization tool, Invex.NxG provides simultaneous voice and data testing on 2G and 3G to 3.9G networks, all while recording subscriber equipment and network independent measurements. The Optimization mode also enables the user to detect neighboring cell sites/sectors and measure sources of internal and external interference.

The i.Classic, when used to optimize a network can be used with up to two digital scanning receivers and allows the simultaneous use of multiple handsets, scanners, and mobile data cards.

Benchmark Mode

When used to benchmark a home network against a competing network, Invex.NxG* can quickly compare network performance by collecting and displaying key performance indicators from multiple mobile data cards, handsets, and scanners.

The Benchmark mode enables simultaneous voice and data testing for multiple technologies while independent TCP/IP stacks allow for accurate measurement of forward and reverse throughput for each 3G to 3.9G device.

The “user experience” or Perceptual analysis is carried out using Mean Opinion Scoring (MOS) that enables users to benchmark voice quality from their own network or competitive networks. Perceptual analysis utilizes PESQ 862.1 or Squad LQ, real-time MOS scoring algorithms, to ensure accurate voice quality results. With the ability to accommodate up to 16 devices per chassis, comprehensive benchmarking takes less time and money.

* MOS is only available with the i.Classic and requires a fixed end Audio Source & Record (ASR).
