NTT Develops 60 GHz Transceivers Delivering 15 Gbps

Researchers at Nippon Telegraph and Telephone Corporation (NTT) announced the world’s smallest wireless transceivers that cover all four of the channels*1 allocated in the 60-GHz band.

The 60 GHz transceivers have a maximum transmission rate of 3.8 Gbps per channel. Simultaneous four channel transmissions makes the transmission rate about 15 Gbps.

NTT said the 60 GHz technology could be used in kiosks located in public venues that would wirelessly download of gigabyte-class content (e.g., a DVD of 4.7 GB) in about 10 seconds,

In Japan, as per the revisions to the Radio Act in September 2011, four channels without licenses can be used for such an application.

The miniaturized transceivers are packed in a wireless module in which a broadband antenna and MMICs are integrated in the multi-layer LTCC substrate. It can cover all four channels.
