In more news from regulators, Ofcom, the UK agency charged with achieving the most efficient use of the spectrum, commissioned another study which mapped the use of spectrum throughout the UK. Several anomalies turned up in the study. Just north of Cambridge, high powered transmissions can be detected in the 863- to 870-MHz band that is ostensibly for the use of short-range devices such as remote light switches and car key fobs. Another surprise was a mysterious signal at 1.075-GHz coming from the Cumbrian village of Millom. The mystery was soon solved without any need for the investigative wiles of a Sherlock Holmes. The signal was tracked to a small shopkeeper operating an illegally imported closed circuit TV setup.The entire report on spectrum mapping can be viewed on the Ofcom website.
