SMEMS

System for Management of Electro-Magnetic Space
Deployment of Radio Relays (pink) and Radio Nets (red)

Efficient and effective spectrum management will ensure that the spectrum is fully exploited to fit in maximum number of emitters and receivers in a confined space, with limited availability of spectrum and with no interference.

SMEMS is the perfect solution to the exponential increase in emitters in Battlespace. Axis’ SMEMS is simulation engine based architecture with online connectivity to spectrum planners, EMI/EMC agencies and field commanders. It can resolves interference problems online.

SMEMS is a Linux; client/server based automated spectrum assignment manager that supports operational planning as well as real-time management of radio frequency spectrum by performing appropriate checks for compatibility and link engineering.

SMEMS predicts and displays electromagnetic spectral occupancy at any geographic point based on selected propagation criteria.

Spectral Density Contours of Deployed Radio Stations

Frequency Assignment

  • Handle requests, grants and denials with respect to EMS assignments
  • Proposing new frequencies using engineering algorithms
  • Create frequency lists for user allotments and channel plans
  • Nominating frequencies for frequency hopping radio sets working in vicinity in a high-spectrum usage density environment
  • Assigning optimization schemes based on Operational Research/Artificial Intelligence techniques
  • Manual/automated stochastic frequency assignment
  • Channel calculation according to WPC recommendation

Interference Analysis

  • Performing an interference analysis considering factors such as equipment characteristics, susceptibility, spurious emissions, terrain etc
  • Determines possible causes of RF interference
  • Perform adjacent and co-channel interference analysis
  • Supplement modules to analyse co-site, inter/cross modulation to get the overall interference result
  • Analyze space and band records
  • Integrated GPS receiver

Engineering Module

  • Perform point to point link analysis
  • Plot Radio LOS and receiver signal strength coverage of a transmitter
  • Perform HF propagation analysis
  • Perform satellite link engineering and predict the footprint
  • Supports multiple coordinate systems such as lat/long, military grid, geo-magnetic systems
