previous generation WLAN / WiFi modules

 

With the acquisition of connectBlue in 2014, u-blox also gained access to the connectBlue previous generation WLAN / Wi-Fi modules OWL221a, OWL253, OWL222a, OWS451 with support for the IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and IEEE 802.11n standards.

These ready-to-embed modules are WLAN dual-band and thus fully cover WLAN 2.4GHz and WLAN 5GHz.
