  WiFi Signal





  FCC Max Power Limitations

  (When using a directional point to point application)

  A WiFi Bridge can link your network to another network so that resources like Internet can be shared. Bridging devices

  work together in pairs so you will need two units. One unit is placed at each network. When a WiFi connection is

  established between both bridging units then the two networks become one.

  A WiFi bridge is different from a WiFi router because it is able to

  connect two networks using WiFi. A normal WiFi router must connect to other networks using an Ethernet cable.


  It is best to initially setup both bridging units in the same room before relocating them to their final location.

  Run the setup CD on a nearby computer and follow the instructions. Once both bridges are communicating with each

  other then you can continue by placing each item in its final location.

  Most WiFi bridging devices come pre-installed with a small antenna that can be upgraded to a

  larger antenna for extended long range WiFi. When using a bridge it is best to mount your antenna outdoors where line

  of sight can be achieved without obstructions. In this case you may need to extend low-loss coaxial cable between the

  antenna jack on the bridge and the outdoor antenna.

  Boosting Power

  If all your equipment is setup and aligned properly and you are still not getting connected then you

  may need to boost the power. This requires another piece of equipment called a WiFi Signal Booster.

  This WiFi Signal Booster

  has two coaxial connectors so it can be placed in-line with the antenna. Connect the “Input” jack on the signal booster

  to the antenna jack on the bridge. Next connect the “Antenna” jack on the signal booster to the coaxial cable

  that leads to your outdoor antenna. If you’re using the

  linked signal booster above with the equipment used in this illustration, then you will

  also need a

  special connector fitting

  along with a

  special pigtail. For even more power add a WiFi signal booster to both bridges.

  FCC Power Output Rules

  Unfortunately there are power restrictions (laws) when using WiFi that if exceeded could land you in jail. The FCC limits

  your total power output using a sliding scale. The scale starts at 30dBm of amplification power while using a 6dBi

  directional antenna. Then for every 1dBm you drop in amplification power you can increase the power of your

  directional antenna by 3dBi.

  Using a larger point-to-point antenna, your beam pattern will cover less area and cause less interference for others.

  This is why the FCC allows this sliding scale.

  Other Solutions

  There is now an easier and more affective way to create a WiFi Bridge by getting the

  Extended Long Range WiFi Bridge System from C. Crane.

  Also check out the new

  CC Vector WiFi Repeater Systems. It latches on to any distant WiFi hotspot and repeats the signal in your

  home, boat, or RV. Works great for boosting the WiFi signal on a Android or Apple cell phone or tablet.
