Positioning API Developer's Guide

Supported Network Technologies

The Positioning API accepts measurements for 2G/3G/4G cellular or WLAN radio bands. The supported technologies are:
  • GSM
  • WCDMA
  • TD-SCDMA
  • LTE
  • CDMA
  • WLAN
For examples on how to use these technologies, see the Examples.

A request can contain measurements from different radio technologies. The total number of cells in a single request and the amount of WLANs is limited. For more information on the detailed numbers, see the API Reference. Do not include the same cell or WLAN multiple times in a request.

All the measurements are expected to be from the same location. If the device is moving, all the measurements have to be from the same moment of time (within seconds). Pay special attention to WLAN measurements as some client side APIs report stale WLANs in addition to the current ones. For recommendations on how to enhance accuracy, see Tips for Optimizing Data Accuracy.

Optionally, the request can also supply network measurements of neighboring cells.

The following is an example of a GSM cell measurement with neighbors:

{
  "gsm": [{
  "mcc": 262,
  "mnc": 1,
  "lac": 5126,
  "cid": 16504,
  "nmr": [
     { "bsic": "6", "bcch": "82" },
     { "bsic": "7", "bcch": "85" },
     { "bsic": "12", "bcch": "93" },
     { "bsic": "13", "bcch": "88" },
     { "bsic": "19", "bcch": "88" }
  ]
  }]
}
