What is G-Link? 
G-Link is a low-power wireless connection that enables instantaneous transfer of gigabits of data between two devices a few centimeters apart.

G-Link makes data sharing easier, quicker and smarter:
  • Gigabits data transfer in a few seconds
  • Wireless
  • Extended battery life
  • Easy to use
  • No need for network access, cable or connector
  • Available anywhere (interfaced with any device USB, HDMI etc.)
  • Secure, confined point-to-point connection
  • More reliable because it requires no ports (waterproof, dustproof)
  • Very small size


Applications: 
For consumers:
Ultra-high-speed wireless connection between two mobile devices to share HD videos, between a movie camera and a video display, between a kiosk and a tablet to download HD videos, etc.

For industry:
In addition to above, secure application in industrial environments where cable reliability is a concern for data transfer. For example, any device in which connectors are affected by rotation, vibration or pressure that reduce lifetime can be replaced by G-Link.

What’s new?
Today, high-speed wireless connectivity uses mainly the WiGig standard (802.11ad)at the 60 GHz frequency band. Power consumption of existing products in WiGig is very high. Leti’s G-Link provides a 10-20x lower power solution for a high-speed wireless link over short distances. Moreover, G-Link uses a very compact and low-cost package, integrating the entire system, including antennas. 

Antenna included on chip:
  • Leti has included an antenna on chip to enable maximum miniaturization and reduce packaging costs. 
  • Solutions without antenna integrated on chip, with standard CMOS technologies, require additional assembly steps that result in higher costs.

Works with 60GHz worldwide RF band:
  • No need for network to connect two devices
  • No need for compliance with any existing communication standard

Low cost:
  • Standard low-cost package (QFN)
  • Small silicon area in low-cost process (65 nm CMOS)
  • No connector for data transfer


What’s next?
G-Link 2nd generation will provide increased data rate (5 Gbps) at lower power consumption (50 mW). 
Further steps will be towards higher frequencies (>100 GHz) to exploit wider bandwidth targeting a data rate of 25-40 Gbps per link. 
Leti is cooperating closely with industrial companies to design the first mass-market generation as well as to define future generations of chips.
