WiGig USB 3.0 adaptor to demonstrate 4K video streaming at CES 2015
WiGig USB 3.0 adaptors are expected to play a fundamental role in the emergence of WiGig enabled devices in the 2015 consumer electronics marketplace.
Peraso’s WiGig RF IC is the smallest, highest performing on the market, ready for integration into next generation mobile and CE devices. The company will be demonstrating key WiGig applications, including: wireless 4K display, multi-gigabit file transfers, and Wi-Fi networking.
Peraso recently launched its 60 GHz WiGig RF IC for consumer electronics — available in two BGA versions, the PRS1125, and the PRS1025, which includes an integrated antenna.
The PRS1025/1125 feature a silicon area is less than 5mm2, and the packaged devices are 49mm2 and 36mm2 respectively. Key features of the product include: P1dB of 14 dBm, EIRP (integrated antenna version) of 24 dBm, receiver noise figure of 4 dB, transmit EVM of -24 dB (64QAM, single-carrier), and receiver noise figure of 5 dB.
Covering 57 GHz to 66 GHz, The RF ICs support up to MCS12 of the IEEE802.11ad specification and offer high-speed 1.5 Gb/s OOK mode.
The high WiGig data rate of 4.6 Gb/s facilitates a host of applications not available through standard WiFi connectivity. With the rapid growth of 4k video, WiGig is an ideal technology for high resolution, low latency wireless screen mirroring. Using WiGig, large media files are transferred between devices in a matter of seconds, not only providing the consumer with next generation convenience, but done so wirelessly. Moreover, as Internet access quickly advances to gigabit data rates, WiGig wireless connectivity ensures that consumer electronics devices keep pace with the entire network. This is critical for cloud-based applications where the user experience must be identical to using locally stored applications.
The PRS1025/1125 targets a variety of consumer electronics devices, including mobile phones, laptops, tablets, monitors, TVs, WiFi access points. In particular, the RF IC coupled with the recently announced PRS4000 WiGig baseband IC, is ideal for implementing a USB 3.0 dongle, a device which enables an entire ecosystem of legacy USB 3.0 enabled devices. Additionally, a compelling feature of the PRS1025/1125 is the support of OOK mode which allows customers to address a host of short range, low cost applications such as wireless connectors.
The rationale for WiGig
WiGig is an ideal wireless technology for the extremely high bandwidth demands of 4K screens. The low latency aspect of WiGig is critical for interactive applications such as gaming, VoIP, and simple I/O functions such as mouse and keyboard.
As media files such as UHD movies increase in size, rapid I/O technology such as WiGig is critical to allow the transfer of files between a host of CE devices such as laptops, smartphones and tablets. While USB 3.0 is fast, WiGig is fast and wireless, eliminating the need for the correct wires and a physical connection.
WiGig is a point-to-point solution, as well as a networking solution along the lines of a traditional Wi-Fi network. One primary application is the simultaneous use of a tri-band access point. Multi-gigabit internet access will be a key advantage of WiGig, particularly as cloud-based applications become increasingly pervasive.
"External adaptors have always played a critical role in emerging wireless standards such as Wi-Fi and Bluetooth," says Ron Glibbery, President and CEO of Peraso Technologies. "We’re proud to be the first WiGig IC vendor to demonstrate the broad utilization of USB 3.0 adaptors for use in the WiGig ecosystem."
