Wireless connectivity solution lets eight devices connect at once

Advanced embedded solutions provider, Cypress Semiconductor, has announced that e.solutions, a joint venture of Audi and Elektrobit, has integrated Cypress’ wireless connectivity solution into its design for new in-vehicle communication units, including in the 2018 Audi A8. Drivers and passengers have the ability to connect up to eight devices at once to the Alpine communication unit’s WiFi hotspot leveraging Cypress’ 802.11ac and Bluetooth combo solution.

As the software stack and design and development supplier of the communication unit, e.solutions selected Cypress’ solution to achieve maximum performance. The company claims that the solution is the industry’s first to implement Real Simultaneous Dual Band (RSDB) technology which enables two unique data streams to run at full throughput simultaneously by integrating two complete WiFi subsystems into a single chip.

Cypress is demonstrating its next-gen automotive wireless connectivity solution, along with its complete embedded systems solution portfolio, at the Embedded World trade show in hall 4A, stand 148 of the Nuremberg Exhibition Centre from 27th February to 1st March.

“The dynamic infotainment user experience enabled by e.solutions design illustrates how our wireless combo solutions pave the way for connected cars,” said Sudhir Gopalswamy, Senior Vice President of the Microcontrollers and Connectivity Division at Cypress. “The design also demonstrates the opportunity we are seeing for new semiconductor content in vehicles as automakers increasingly use in-cabin electronics to enhance the user experience.

"Beyond the automotive market, it shows how Cypress is partnering with our customers to solve their design problems and bring their innovative ideas to market.”

The e.solutions communication unit design uses Cypress’ CYW89359 combo solution, which includes an advanced coexistence engine that enables optimal performance for dual-band 2.4 and 5GHz 802.11ac WiFi and dual-mode Bluetooth/Bluetooth Low Energy (BLE) simultaneously for superior multimedia experiences.

Its RSDB architecture enables applications such as Apple CarPlay and a WiFi hotspot to operate concurrently without degradation caused by switching back and forth between bands.
