Monitor keeps track of RF emissions
The new 2600 area monitor system from Link Microtek enables continuous remote monitoring of RF radiation levels in the vicinity of mobile phone basestations and other communications antenna sites
Manufactured by Narda Safety Test Solutions, the 2600 system provides a constant stream of accurate data and represents a major step forward from one-off manual measurements, which are both time-consuming and expensive because of the need for an engineer to visit the site. In addition, the system picks up time-related variations in RF radiation levels, which could easily be missed by conventional measurements.

For example, antenna power levels may rise significantly at different times of the day, depending on the amount of call traffic.
With the 2600 system, data are collected on site by the area monitor units and then, at user-defined times, transmitted via a GSM link to a central computer.
Special AMS 2600 software on the computer is used to analyse the data and present it in an easy-to-read graphical format, and this information can then be made available to the general public via the Internet, for example.
Each 2600 area monitor unit is completely self-contained and requires only minimal maintenance.
Powered by a combination of solar panels and rechargeable batteries, the area monitor includes an RF radiation probe to suit the requirements of the particular application, a large internal memory that stores up to 18 months of data (depending on the type and frequency of measurements being made), and a GSM modem to allow communication with the central computer or text messaging to specified mobile phones.
Stored data are downloaded to the central computer either automatically at preprogrammed times or manually in response to a remote command.
The area monitor can also be set up to automatically call the central computer and text up to ten mobile phones in the event of an alarm condition, eg if the RF field level exceeds a user-specified threshold, the case has been opened or the battery level is low.
The AMS 2600 software running on the central computer is used to configure area monitor parameters such as alarm thresholds, data acquisition rate, measurement type and data transfer times.
Once downloaded into the computer, data can be stored for future reference, analysed and printed out in a variety of formats, or exported into other applications for further analysis and presentation.
