Our engineering capabilities in this area extend all the way from assessment of the basic transmission media such as copper cable or radio channel, through to high-level protocol analysis as follows:

• Channel bandwidth and signal-to-noise;

• Assessment of channel capacity;

• Noise & Interference investigations;

• Bit-Error-Rate (BER) and Packet Error Rate (PER) Analysis;

• ITU-T & ITU-R Standards Compliance;

• Throughput & Capacity Analysis.

Our investigation services are complemented by high-quality documented reports. Where clients have an interest in developing these capabilities in-house we are happy to provide appropriate technology-transfer arrangements including training seminars.
