Remote radio monitoring platform automates spectrum surveillance
Designed without a display or keyboard, the remote spectrum monitor automates the method of conducting radio surveillance, interference detection, and government spectrum policy enforcement while bringing greater flexibilities and cost efficiencies to network management.
The bundled solution is flexible and expandable to evolve along with networks, it features two spectrum monitor modules at introduction, each with power of arrival (POA) algorithms to monitor for interference and approximate the position where the interfering signal is being generated.
Designed to maximize network capacity by more efficiently solving issues associated with the presence of illegal or unlicensed signals that interfere with authorized transmissions, the MS27102A can be wall- or pole-mounted and will operate within the -40 to +55ºC temperature range. Certified with an IP67 rating, it has one (or optionally two) weather-resistant RF In ports, a rugged weatherized case and splash proof design for the most extreme weather conditions.
The MS27103A helps operators provide quality services to consumers and meet KPIs for a maximum return on network investment. Designed for multiple antenna applications that cover wide frequency ranges, the unit has a rack-mountable multi-port RF In probe that constantly monitors the spectrum to ensure optimal performance. Anritsu has developed this monitor for cellular operators requiring spectrum monitoring coverage for multiple sectors and numerous frequencies per sector at their BTS locations.
Covering 9 kHz to 6 GHz, the probes have sweep rates up to 24 GHz/s, allowing capture of many interferers, including periodic or transient transmissions as well as short “bursty” signals. The modules also have low power consumption of below 11 watts.
The spectrum monitor probes are designed for robust field deployments, with capabilities for remote power cycling, automated system recovery protocols and secure firmware updates. A “Golden” firmware image is placed on each unit and can be used to return the probe to full operation in the rare case the firmware is corrupted.
Anritsu has developed Vision Application Software to automate collecting measurement data, providing useful information about network heath and spectrum use. Vision Monitor automatically records spectrum data, maintains a searchable spectrum history database, enables alarm functions for unusual signal activity and provides tools for managing the spectrum monitoring system.
Users can also write custom monitoring program applications using available SCPI commands. Each pair of IQ data output is time-stamped using high precision GPS signals, allowing the IQ data to be used for Time Distance of Arrival (TDOA) applications for geo-locating signal positions. IQ data time stamp resolution is less than 9 nSec for precise signal location calculations. An integrated web server is embedded into each spectrum monitor probe, offering remote log from either Chrome or FireFox to control the instrument’s features using a PC/laptop, tablet or smartphone.
