Measuring mobile networks

Mobile telephony is an increasingly important part of both the business and public sectors. In order for the mobile phones to function you need a well-run mobile telecommunication network both indoors and outdoors, when standing still and while on the move.

The first step to a better mobile coverage is control of the coverage with specialised equipment performed by experts in the field, thereby mapping holes in the coverages and/or other malfunctions in the infrastructure.

Ramboll offers drivetests as well as indoor measurements with portable equipment. These include everything from a thorough benchmark drivetest, where all operators are compared, to indoor coverage control, where a single operator is measured.

The various types of networks – 2G (GSM), 3G (UMTS), and 4G (LTE) – create challenges when tasked to work together across various frequency bands.

Drivetests

Drivetests are performed by a customised measuring van, on which an antenna is fitted for each of the various measuring instruments. This ensures that the instruments have consistent and repeatable conditions and makes it possible to simulate indoor coverage by turning down the signal strength.

What can be measured?

  • Signal strength (coverage) on 2G, 3G, and 4G
  • Signal quality on 2G, 3G, and 4G
  • Speech quality
  • Rate of dropped and failed calls
  • Data speed (IP Throughput)
  • SMS/MMS (success rate/speed of delivery)
  • Video stream (YouTube)
  • E-mail

Drivetests in trains

Drivetests in trains (including benchmark) are performed with portable measuring equipment with GPS that ensures that the measurement data can be displayed on a map. The measurements usually do not require a special train, but can be carried out in regular trains, as a regular passenger.

What can be measured?
  • Signal strength (coverage) on 2G, 3G, 4G and WiFi (WLan)
  • Signal quality on 2G, 3G, and 4G
  • Speech quality P.OLQA.
  • Rate of dropped and failed calls
  • Data speed (IP Throughput)
  • SMS (success rate/speed of delivery)
  • Video stream (YouTube)

Indoor measurements (walktest)

In locations where a drivetest is not possible, portable measuring equipment is used. This enables us to perform various tests, such as coverage control of indoor coverage, and faults on indoor mobile installations can be discovered. It is possible to measure both external signals as well as indoor installations.

What can be measured?
  • Signal strength (coverage) on 2G, 3G, 4G, and WiFi (WLan)
  • Signal quality on 2G, 3G and 4G
  • Rate of dropped and failed calls
  • Data speed (IP Throughput)
  • SMS (success rate and speed of delivery)
  • Video stream (YouTube)
  • E-mail
