ARIB STD-T104

ARIB STD-T104 defines the technical requirements for LTE-Advanced (IMT-Advanced, 4G) systems in Japan. The standard aligns with 3GPP LTE-Advanced specifications but is adapted to Japan’s domestic frequency allocations and regulatory framework.

Scope and Application

The standard applies to public mobile communication networks and devices operating under Japan’s Radio Law. Compliance with STD-T104 ensures efficient spectrum use and interoperability of LTE-Advanced equipment in the Japanese market.

Frequency Bands and Operation

LTE-Advanced under STD-T104 is deployed in multiple Japanese IMT bands, including:

• 700 MHz

• 800 MHz

• 1.5 GHz

• 1.7 GHz

• 2 GHz

Key Technical Features

• Carrier Aggregation for higher throughput

• Multiple-Input Multiple-Output (MIMO) support

• Orthogonal Frequency Division Multiple Access (OFDMA) downlink

• Single-Carrier Frequency Division Multiple Access (SC-FDMA) uplink

• Adapted revisions reflecting 3GPP Releases 10 through 13 (by 2017)

Certification and Labeling

All LTE-Advanced devices must be tested and certified by a Registered Certification Body (RCB) under Japan’s Radio Law. Approved devices bear the Giteki mark with the assigned certification number.

For support with testing and approval, see our → MIC Certification Services.

Note
A comprehensive overview of device categories, certification process, and Giteki marking can be found in the guide → MIC Requirements – Overview.
