2x to 3x eXtended Range
TM
WLAN Transmission Technology - The WLAN device
with 2x to 3x eXtended Range
TM
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
TM
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
transmission distance is about 300m, A 2x to 3x eXtended Range
TM
based client and
access point 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.
