1. (general descriptions)

This W2 module is a low power consumption 150 M USB wireless high fidelity card, compatible IEEE802.11 b/g/n standard, can meet the standard with other wireless equipment connected each other, 64/128 of the latest communications support a WEP, WPA data encryption WPA2 PSK/support- PSK, WPA/WPA2 security mechanism, wireless transmission rate is as high as 150 M, with the smart antenna, and may also be to an external antenna make the transmission distance farther, can adapt to different environment for desktop and laptop computers and tablet computer, network video camera, STB, GPS and other need to implement wireless networking equipment convenient to access a wireless network.

This module can choose 5 V power supply or 3.3 V power supply, we will according to the demand of customer production setting.

This module is built-in antenna and external antenna design, the customer when using compatible plate can be directly use ceramic antenna, can also through the external antenna gain higher, we will according to the demand of customer before they set in.
