4w Outdoor Repeater WIFI signal receiver China cheapest, waterproof wlan booster ,wifi signal booster

Why do you need to buy repeater/booster?

Cell phone becomes especially helpful when people get into critical situations. In case of emergency a timely call can save somebody’s life.

Unfortunately, there are still some places where they can find themselves “out of coverage” ,no signal at all... Usually those places are either too far from the cell phone base station or located inside underground constructions, for example:

• Parking lots, tunnels
• Big stores, office buildings
• Cars, boats etc.
• House in remote areas

How can repeater bring your mobile phone better signal?

•The outside antenna catches low signal from operator servicer’s base station and delivers it to cell phone repeater through the connection cable (coax).

•After the signal is accepted by the mobile repeater, this device amplifies it.

•Then this amplified signal goes through the connection cable (coax) to the inside antenna.

•And after that, the amplified signal transmits to your cell phone.

• Finally, your cell phone will get good signal, never on and off

Specification should care about: 

A regular cell phone repeater consists of: (full kit)

• 1 -Outdoor antenna log periodic antenna(or wall mounted, yagi antenna)
• 2 - Indoor Omni ceiling antenna( panel antenna) 
• 3 – Power adapter 
• 5 - User manual
• 6 - Cell phone repeater
• 7. 10 meters outdoor cable and 1 meter indoor cable 

Instructions :

1: Connect Antenna to the Wi-Fi Booster.

Caution: The Booster antenna interface can only connect antenna, Don't connect to any other wireless products in any case, otherwise it will result in equipment malfunction or damage.

2: Connect Wireless AP/Router or Wireless Network Card to the Wi-Fi Booster.

Tips: Users can also use other shielded cables to connect, but the cable length should be as short as possible, preferably not exceeding 3m.

3: Power up the Wi-Fi Booster.

At first, the Light of the LED is very dark. When the data is being transmitted, the light will become very bright. The more dense data transmission, the more bright light.

Caution: Before Power up the Wi-Fi Booster, you must Power up the AP/Router first.

4:  Adjust the Antenna position and angle, make the Wi-Fi Booster achieve the best performance.

The adjustment method of the Downlink Gain :

Attention

1: The default Downlink gain is 13dB, It is not the higher the better, You must ensure that the final transmit power must not be larger than 36dBm (4w).

 2: The Downlink gain is too high may cause the booster not work correctly, The wireless link cannot be successfully connected, or even lead to the booster damage.

3: You need to reduce the Downlink gain when it's combined with a high-power AP/Router.

4: You need to increase the Downlink gain when it's combined with a low-power AP/Router.
