u-blox’ (Thalwil, Switzerland) LILY-W1 is a single band 802.11n 2.4 GHz Wi-Fi transceiver module measuring 10 x 14 mm, for providing Wi-Fi connectivity to industrial and commercial products with LTE connectivity.

LILY-W1 simplifies the integrator's RF design efforts with an integrated antenna and enables Wi-Fi in-device co-existence with LTE thanks to a bulk acoustic wave filter. The filter not only ensures that Wi-Fi performance does not deteriorate in proximity of an LTE transceiver, but allows the antennas of both transceivers to be sited close together. The new module also supports Wi-Fi direct.

LILY-W1 connects to the host processor, either through SDIO or USB, and can operate concurrently in Client and Micro Access Point modes. Up to eight clients can attach when functioning as a Micro Access Point. Royalty-free Linux and Android drivers are provided as standard. With its extended temperature range from -40 to +85 degrees C, the module connects industrial and commercial equipment. Typical applications can include telematics control units, drive recorders or OBD readers, as well as logistics or point of sales equipment.
