Data

• hw_device: processor
• hw_model: mobile phone model
• lon, lat: coordinates
• RSSNR: Reference Signal Signal-to-Noise Ratio
  • Signal to noise ratio, measured using a certain reference signal
• RSRP: Reference Signal Received Power
  • received power at the mobile device
  • used by the mobile phone to determine best cell tower to use
• CQI: Channel Quality Indicator
  • value for signal quality
  • influenced by signal strength, noise, intereference levels, etc.
• model: mobile phone model (again?)
• RSRQ: Reference Signal Received Quality
  • ratio between signal power and noise, inference power
• RSSI: Received Signal Strength Indicator
  • only shows absolute received signal power
