We get asked all the time about WiFi signal improvement. Improving WiFi signal is similiar but easier and less expensive than cellular signal improvement. WiFi signal improvement starts with analyzing where you need your signal and shaping your WiFi network to your needs.
WiFi Antennas
WiFi Directional Antenna
Most antennas that come with wifi products are low-gain, omni directional antennas. That means they send signal equally in all directions. A lot of that signal could be going in directions where you don’t need it. You can add a directional WiFi antenna to point more of the signal in one direction. For instance, if your in a long rectangular shaped building and your wireless access point is on one end of the building, you many want to add a directional WiFi antenna to point the signal across the building. Of course simply moving your access point to the middle of the room, away from obstructions is sometime the least expensive and simplest way to improve signal but if a move is not possible, consider a directional antenna.
WiFi Cards & Access Points
If adding a directional antenna is not enough, you can add one or more additional access points. The typical wireless router (with built-in access point) and built-in laptop wifi puts out around 40 milliwatts of power. For reliable indoor use or long-range outdoor use, you need to maximize your signal and bandwidth. For a very low cost, you can build a system that can put out from 100mW to 1000mW.
You can overdue WiFi signal improvement with wifi signal boosters (access points, adapters, cards, amplifiers, etc) that create a lot of negative signal noise in your area that effects other WiFi users. The most powerful is not always the best for yourself or your neighbors.
