60GHz mesh solution for wireless infrastructure

The chipset consists of a BCM20130 baseband SoC and a BCM20138 RF transceiver chip, both of which are implemented in standard CMOS process. Based on steerable beam forming technology, the chipset provides a robust, cost effective 60GHz wireless solution addressing the ‘last mile problem’ for wireless infrastructure.

Broadcom’s 60G WiMesh technology enables a baseband SoC to connect to multiple RF transceiver chips, supporting large phased array antennae to extend data transmission range. The solution can also employ a custom time division duplex (TDD) protocol to facilitate long range point-to-multi-point links to enable a robust wireless mesh network.

Compared with other 60GHz wireless solutions on the market, which are either short range or expensive, the Broadcom® 60G WiMesh solution does not need high gain fixed antennae and allows the formation of a self-organising, community-based wireless mesh network in the 60GHz spectrum, which minimises equipment and infrastructure costs and provides a highly efficient, high bandwidth data delivery for mobile backhaul.

Broadcom 60G WiMesh solution benefits

• Provides a lower cost 60GHz wireless solution for the ‘last mile problem’ compared to traditional backhaul solutions.
• Enables OEMs and service providers to offer extended range WiGig compliant access points.
• Delivers enhanced end user experience through faster connectivity leveraging 60GHz wireless mesh backhaul to fibre ‘point of presence’.

Broadcom will demonstrate the 60G WiMesh technology in the Broadcom Booth 629 at the 2016 International Microwave Symposium (IMS) exhibition in San Francisco, California from 24th-26th May. Attendees will experience first hand live traffic stream of IEEE 802.11ad data transferring up to 4.62Gbps between two transceivers.

“Built upon a well established RF/Analogue CMOS design and standards-based solution, the Broadcom 60G WiMesh solution is the first in the industry to support wireless mesh networking in the 60GHz band with link distances between nodes up to hundreds of metres, making it ideal for use in wireless backhaul. Furthermore, the 60G WiMesh technology bolsters Broadcom’s Wi-Fi leadership and enables us to deliver the best user experience by providing end-to-end multi-Gbps connectivity,” said Michael Hurlston, Senior Vice President and General Manager of the Mobile Connectivity Products Division at Broadcom.

“Worldwide user demand for data on the go is far outpacing the ability of service providers to add low cost capacity through access densification,” asserted Joe Madden, Principal Analyst at Mobile Experts. “60Gig WiMesh lowers the barrier for operators and OTT players to add bigger bandwidth, at lower TCO than traditional wireless backhaul.”
