¾ 108M Super GTM WLAN Transmission Technology - 108M Super GTM WLAN

Transmission Technology employs multiple performance-enhancing techniques including

packet bursting, fast frames, data compression, and dynamic turbo mode that combine to

improve the throughput and range of wireless networking products. Users can experience

link rates of up to 108Mbps, twice the industry-standard maximum data link rate of 54Mbps,

while preserving full compatibility with traditional 802.11g or 802.11b networks. 108M Super

GTM products offer the highest throughput performance available on the market today. In

dynamic 108M mode, the device can attach 802.11b, 802.11g and 108Mbps Super GTM

devices at the same time in an integrated environment.

¾ 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 TP-LINK 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 product 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.

¾ Ad-hoc Network - An ad-hoc network is a group of computers, each with a wireless

adapter, connected as an independent 802.11 wireless LAN. Ad-hoc wireless computers

operate on a peer-to-peer basis, communicating directly with each other without the use of

an access point. Ad-hoc mode is also referred to as an Independent Basic Service Set

(IBSS) or as peer-to-peer mode, and is useful at a departmental scale or SOHO operation.

¾ DSSS (Direct-Sequence Spread Spectrum) - DSSS generates a redundant bit pattern for

all data transmitted. This bit pattern is called a chip (or chipping code). Even if one or more

bits in the chip are damaged during transmission, statistical techniques embedded in the

receiver can recover the original data without the need for retransmission. To an

unintended receiver, DSSS appears as low power wideband noise and is rejected (ignored)
