™
2x to 3x eXtended Range WLAN Transmission Technology - The WLAN device with 2x to 3x
™
eXtended Range WLAN transmission technology make its sensitivity up to 105 dB, which gives
users the ability to have robust, longer-range wireless connections. With this range-enhancing
™
technology, a 2x to 3x eXtended Range based client and access point can maintain a connection
at as much as three times the transmission distance of traditional 802.11b and 802.11g products, for
a coverage area that is up to nine times greater. A traditional 802.11b and 802.11g product
™
based client and access point
transmission distance is about 300m, a 2x to 3x eXtended Range
can maintain a connection transmission distance may be up to 830m.
802.11b - The 802.11b standard specifies a wireless networking at 11 Mbps using direct-sequence
spread-spectrum (DSSS) technology and operating in the unlicensed radio spectrum at 2.4GHz,
and WEP encryption for security. 802.11b networks are also referred to as Wi-Fi networks.
802.11g - specification for wireless networking at 54 Mbps using direct-sequence spread-spectrum
(DSSS) technology, using OFDM modulation and operating in the unlicensed radio spectrum at
2.4GHz, and backward compatibility with IEEE 802.11b devices, and WEP encryption for security.
