Hawking Technology's HWUG1, 2.4Ghz Wireless-G USB 2.0 Network Adapter with removable antenna, packs the latest wireless technology into a compact unit, capable of transferring data at speeds up to 54Mbps and 108Mbps, capable when paired with the Hawking HWRGM1A Mimo Router. The external dipole antenna can easily be removed and upgraded to a Hawking Hi-Gain Antenna for extended wireless range. For piece-of-mind wireless security, the HWUG1 supports 64/128-bit WEP data encryption that protects your wireless network from eavesdropping. It also supports the WPA and WPA2 (Wi-Fi Protected Access) security standards that combines IEEE 802.1x and TKIP (Temporal Key Integrity Protocol) technologies. Client users are required to authorize before accessing to APs or AP Routers, and the data transmitted in the network is encrypted/decrypted by a dynamically changed secret key.
