The TomTom GO Discover is one of the fastest and most powerful satellite navigators on the market today, developed by location services company TomTom. Navigators with 5-, 6- and 7-inch displays use the combined Bluetooth / Wi-Fi chips CYW43455 of the AIROC family from Infineon Technologies. AIROC's wireless solution combines Wi-Fi (802.11.ac) and Bluetooth 5.0 on a single chip to provide the fast and stable connection that is critical for a navigation device. Infineon's AIROC family includes a wide range of wireless solutions that provide reliable, high-speed connectivity.
TomTom Go Discover downloads map updates three times faster than other navigation devices that use the integrated 5GHz Wi-Fi frequency band. In addition, thanks to the built-in Bluetooth interface, TomTom Go Discover can also be connected to a smartphone, making real-time traffic information and premium TomTom services always available. This service includes up-to-date information on fuel prices, availability of parking spaces and the location of charging stations for electric vehicles.
“The low-power products in our AIROC wireless portfolio use advanced design and information technologies to reduce power consumption both during operation and in sleep mode,” said Sivaram Trikutam, Senior Director, Computing and Wireless IoT at Infineon. “In addition, the chip that supports 1x1 spatial streams integrates high-level processing hardware and algorithms to optimize WLAN and Bluetooth collaboration for best performance. As a result, the chip is ideal for mobile navigation devices that require reliable wireless interfaces to provide drivers with up-to-date traffic and other relevant information.”“Designed with safety in mind, the new TomTom GO Discover makes every journey more enjoyable,” said Mike Schoofs, Managing Director, TomTom Consumer. “Using Infineon's AIROC wireless connectivity solutions, we've been able to equip the sat nav with powerful and fast wireless interfaces to keep the device's traffic and map information up to date on a regular basis. This chip allows us to combine our deep understanding of driver needs with the latest cutting-edge technology.”
Infineon offers AIROC 1x1 Wi-Fi 5 (802.11ac) and Bluetooth wireless connectivity in the 2.4GHz and 5GHz frequency bands. Wi-Fi mode supports 20, 40 and 80 MHz channels for data rates up to 433.3 Mbps, as well as all speeds provided by the 802.11a/b/g/n standard. This triples the throughput and transmission speed of the WLAN and greatly improves scalability.
The high data rate is especially useful for streaming media such as HD video, transferring and storing files, and extending the range of Wi-Fi networks. In addition, Wi-Fi 5 specifications extend battery life. As soon as the Wi-Fi interface completes high-speed communication with its access point, the radio link immediately turns off and returns to sleep mode, reducing overall power consumption.
