AIROC Wi-Fi & Bluetooth Combo Chip Offer Connectivity for TomTom's Satellite Navigation

TomTom GO Discover, developed by TomTom, is a satellite navigation (satnav) system featuring 5, 6, and 7-inch display and leveraging the AIROC CYW43455 Wi-Fi and Bluetooth combo chip from Infineon Technologies AG.

The AIROC wireless solution combines Wi-Fi 5 (802.11 ac) and Bluetooth 5.0 on a single chip and adds wireless connectivity to the navigation device.

According to the company, the TomTom GO Discover downloads map updates three times faster than other navigation devices, powered by the integrated 5 GHz Wi-Fi frequency band. Furthermore, with the integrated Bluetooth interface, the TomTom GO Discover can also be connected to the smartphone, making both real-time traffic information and TomTom's live services available. This includes up-to-date information on fuel prices, parking availability, and the localization of charging points for electric vehicles.

The AIROC wireless connectivity portfolio offers 1x1 Wi-Fi 5 (802.11ac), Bluetooth, and 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 and rates specified in 802.11a/b/g/n are also supported. Per the company, this triples the throughput and transmission speed over WLAN.

The high-data transmission speed can be beneficial when streaming media such as HD videos, transferring and storing files, as well as for extending the range of Wi-Fi networks. Furthermore, the Wi-Fi 5 specification is designed to help extend the battery life. Once the Wi-Fi interface has exchanged data at a high rate with its access point, the radio is deactivated and goes back to sleep mode.

AIROC Wi-Fi & Bluetooth combo chips are now available.
