The ever increasing usage of the electromagnetic spectrum across civil, defence, and national security applications results in a growing need to effectively monitor this spectrum. Regulators need to be able to monitor it so that the safe and fair usage can be enforced, whilst national security and intelligence agencies can use it gather communications and data of intelligence value.
Our RF over Fibre spectrum monitoring solutions have multiple benefits:
- Increased Detection of Signals of Interest Losing only 0.02 dB over 10m compared to a loss of 3.6 dB over 10m for coaxial cables, an RFoF based solution has no negligible attenuation on the SoI. This means that all signals captured by the antenna can be detected by the modem / receiver, drastically increasing the amount of SoI’s detected.
- Optimised Antenna Placement The lossless nature of the fibre optic cabling used in an RFoF solution removes any constraint on distance between antennas and the modems / receivers. This enables the antenna position to be optimised to reduced interference from other RF emitters, and to improve ‘field of view’ for unimpaired signal reception.
- Any-to-Any Network Topology An RFoF based solution allows any antenna to be mapped to any modem / receiver in less than a second. This dynamic cross-spectrum antenna mapping enables the monitoring system to be rapidly optimised to maximise the amount of valuable data collected from the spectrum. This dynamic signal routing, or any-to-any mapping, removes the previous limitations and unlocks the full capability of modems / receivers.
PPM Systems: proven COTS-based solutions
M543070: For large, permanent monitoring sites
Supports more than 160 antenna feeds from different antenna farms, providing each one of these feeds to more than 1000
modem / receiver end points across multiple data centres. Each end point is able to individually select the desired antenna
feed to maximise useful data gathered.
M543071: For smaller or temporary monitoring sites
Supports more than 10 antenna feeds from the antenna farms on the roof, providing each one of these feeds to multiple
modem / receiver end points in different secure rooms. Each end point is able to individually select the desired antenna feed
to maximise useful data gathered.
