SIQMA - SC2810

CPRI Test Done Brilliantly and Affordably

Summary
SIQMA is the highest performing, lowest cost CPRI analyzer on the market. Unlike any other CPRI instruments, SIQMA not only captures every frame to deliver 100 percent detection of interference problems, it offers simultaneous antenna support without sacrificing performance. By focusing on one application – CPRI analysis – we have brilliantly designed the market’s highest performing instrument at half the price.

 

  • CPRI Packet Sniffer and Data Analyzer
  • Maximum Line Rate 3
  • Small Portable Form Factor
  • Can Be Operated as a Standalone Unit or in Conjunction with an External Spectrum Analyzer
  • Data Collection and Replay Modes
  • Windows-based GUI for Expanded Features

 

Typical Applications

  • Remote Radio Unit (RRU) Deployment
  • Radio Access Network (RAN) Optimization
  • Cell Site Interference Analysis
  • Data Collection and Storage for future and/or offsite analysis

In the past, all signal processing units on the base station were located at ground level instead of the top near the antenna, which leads to path loss due to long RF cabling. Nowadays, to prevent loss due to long RF cabling, the processing unit is divided into a preprocessing unit at the top of the mast, the remote radio unit (RRU), and the base band unit (BBU) located on the ground surface. The digital CPRI link is used to connect the RF unit at the top of the tower to the BBU located at the bottom. While this configuration offers power efficiency, it leads to other issues associated with maintenance, such as needing a technician to climb the mast to connect the signal analyzer via RF cables to see the uplink spectrum.

 

The SC2810 CPRI analyzer provides cell site installers, maintenance operations, and troubleshooters with a convenient tool that can be used on a live site. A low-loss optical splitter is inserted in series with the existing RRU-to-BBU optical cable, resulting in minimal disruption to the site’s operation. Splitters can be left onsite if multiple visits are required.

 

CPRI data can be collected and stored or viewed live. Live data is presented to the user on a Windows GUI or streamed  via a front panel RF connector for analysis with an optional spectrum analyzer.
