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 transmission distance is about 300m, a 2x to 3x
eXtended Range
based client and access point can maintain a connection transmission
distance may be up to 830m.
¾
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.
¾
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.
