    Single Chip With Wi-Fi & Bluetooth Offers High Localisation Performance


    TomTom GO Discover developed by the location technology company TomTom is one of the quickest and powerful satellite navigation systems (satnavs) present today. By leveraging the power of Infineon Technologies’ AIROC CYW43455 integrated with Wi-Fi 5 (802.11 ac) and Bluetooth 5.0, the TomTom GO Discover satnav has 5, 6, and 7-inches displays. The combined chip gives a fast and robust wireless connectivity critical to the navigation device.

    Powered by the integrated 5 GHz Wi-Fi frequency band, the TomTom GO Discover downloads map updates 3x faster than other navigation devices. Furthermore, with the integrated Bluetooth interface, the TomTom GO Discover also connects to the smartphone, making both real-time traffic information and TomTom’s premium live services available at all times, including up-to-date information on fuel prices, parking availability and the localisation of charging points for electric vehicles.

    The AIROC wireless connectivity portfolio operates in the 2.4 GHz and 5 GHz frequency spectrum. The Wi-Fi 5 mode supports 20 MHz, 40 MHz and 80 MHz channels for data rates up to 433.3 Mbps. All rates specified in 802.11a/b/g/n are also supported. This triples the throughput and transmission speed over WLAN and significantly improves scalability.

    Furthermore, the Wi-Fi 5 extends the battery life. Once the Wi-Fi interface has exchanged data at a high rate with its access point, the radio is immediately deactivated, returning to sleep mode, which reduces overall power consumption.

    “Built with safety in mind, the new TomTom GO Discover makes every journey more enjoyable,” said Mike Schoofs, Managing Director of TomTom Consumer. “With Infineon’s AIROC wireless connectivity solutions, we have succeeded in fitting the satnav with powerful and fast wireless interfaces enabling the device’s traffic and map information to be regularly updated. The chip allows us to combine our in-depth understanding of driver requirements with the latest and greatest technology.”

    “The low power products from our AIROC wireless connectivity portfolio utilise advanced design and processing techniques to reduce power consumption during operation and sleep mode,” said Sivaram Trikutam, Senior Director IoT Compute and Wireless at Infineon. “In addition, the 1×1 chip integrates high-level hardware processes and algorithms that optimise the collaboration of WLAN and Bluetooth® for maximum performance. As a result, the chip is ideal for mobile navigation devices that require reliable wireless interfaces to provide drivers up-to-date information on traffic conditions and other relevant information.”

    AIROC Wi-Fi & Bluetooth combo chips are now available from Infineon Technologies AG.
