AIROC CYW43455 Wi-Fi and Bluetooth Combo Chip Delivers Fast and Robust Connectivity to TomTom Go Discover Satnav
TomTom Go Discover satnav (satellite-based navigation system) is leveraging the AIROC CYW43455Wi-Fi and Bluetooth combo chipfrom Infineon Technologies. The AIROC wireless solution combines1x1 Wi-Fi 5 (802.11 ac) and Bluetooth 5.0on a single chip andoperates in the 2.4GHz and 5GHz frequencyspectrum.
In addition to fast and robust wireless connectivity, the AIROC device’s Wi-Fi 5 modesupports 20 MHz, 40 MHz, and 80 MHz channelsfor data rates up to 433.3 Mbps and all rates specified in 802.11a/b/g/n. This triples the throughput and transmission speed over WLAN and significantly improves scalability.
The high data transmission of the device is more advantageous while streaming media such as HD videos, transferring and storing files, as well as for extending the range of Wi-Fi networks. Along With the ability to update three times faster than other similar devices, the TomTom Go Discover can be connected to the smartphone through the integrated Bluetooth interface.
