DOCOMO IOT

DOCOMO

DOCOMO Inter-Operability Testing (IOT) is DOCOMO’s Carrier Acceptance Test (CAT) and it ensures that tested devices are compatible with docomo cellular network.

The testing comprises different scopes and testable items are determined according to each device’s features.

At DEKRA Japan Lab, as a DOCOMO Approved Test Laboratory (D-ATL), we offer testing services for every scope of DOCOMO IOT.

OTA Testing

In the OTA (Over The Air Antenna Test) testing, the antenna performance of the device is tested by measuring several items selected by DOCOMO.

The measurements are conducted in a Bluetest Reverberation Chamber. By this method, not only do we avoid the use of a full anechoic chamber, but also the testing time is considerably reduced.

Moreover, a yearly audit carried out by DOCOMO ensures that our measured results are in line with those of DOCOMO’s in-house environment.

Signaling Testing

DST (DOCOMO Signalling Test) tests the conformance of the device under test to DOCOMO’s protocol specification. The test platform used is Anritsu ME7834L and all tests are run inside a shield room to avoid any interference to and from the live network.

The signaling test consists of two main stages:

  • DRFL (DOCOMO Radio Feature List) Capability Check: This is the initial stage of DOCOMO IOT where we check whether the information declared by the device via signaling matches the one declared by the manufacturer.
  • DST (DOCOMO signaling test): By running different test scripts the test system check the compliance of the device with DOCOMO protocol specification under different scenarios.

Field Testing

The final stage of DOCOMO IOT is testing the device on the live network.

DFTG (DOCOMO Field Test based on GCF-FT) is based on the GCF Field Trial.

The device is tested under different conditions, both in stationary and mobility scenarios.
