Description:
WLAN-2300-1W is an indoor solution 1W bi-direction Booster designed for 2.4GHz wireless LANs. This unit comes with an easy plug-and-play installation, which works together with an indoor Wireless Access Point to improve its operation range and performance. In certain conditions the unit is able to double the range of the wireless device. The unit extends signal range and can eliminate the use of an additional radio with its associated data line, power outlet, signal interference, and setup headaches.
The unit is the fast and easy way to extend your signal range in any environment. The unit is ideal for use with 2.4 GHz frequency hopping or direct sequence spread spectrum radio modems and 11 mbps IEEE802.11b devices.
The amplifiers increase range by providing transmit gain as well as low-noise receive gain. This receive gain increase the receive sensitivity of wireless LAN Access poing. Full output power of 500mW is achieved with only 32 mW input into the Booster.

Features :

* Switching power supply
High efficiency and stability of the new switching power supply so that the signal transmission speed faster and more stable voltage changes, sensitivity stronger, lighter weight.
* Intelligent signal limiter
Each channel has an independent output signal overload distortion, automatic pressure limited function, when the output signals are now clipping distortion can be quickly restored to the output signal compression is not the biggest distortion level and no reduction in the frequency response of audio signals, to avoid DC level because of the audio signal output and burned speakers.
* Multiple detection, multiple protection
A soft start, the second start, the (low) pressure protection, output overload and short circuit protection.
* High efficiency, low fever
Efficient Class H amplifier, significantly reduce heat loss.
* Pristine audio
Metal Packaging, high-power transistors, Yanyi a pure, passionate, authentic audio effects.
* Removable face Network
Removable the hole into the wind-net, easy cleaning.
