Test wifi range1/15/2024 ![]() ![]() A standard WifiĮquipment dipole antenna has vertical polarisation, when mounted vertically. MostĬommonly used are horizontal and vertical polarisation. Of the Electric field of the antenna, in reference to the earth's horizon. Antenna polarisation is defined as the direction The antenna is tilted away from the AP, the antenna has an electrical 'downtilt'.Īccess Point met Omni = Access Point with Omni directional antennaĭirectional and Omni directional antennas both have a If the signal strength increases, the antenna has what You should however notice a change in signal strength when the antenna is tilted When the antenna is rotated around its vertical axis. This means that you should notice little or no variations in signal strength Omni's (Omni directional Antennas) have no directivity. Make sure not to shield (part of) the antenna with You must notice a clear difference in signal Turn theĪntenna around the vertical axis. To the side and rear of the antenna, the signal level is less. Most energy is bundled in a beam at the front of theĪntenna. If signal level is high with and without the externalĪntenna connected, try increasing the distance between the two devices.ĭirectional antennas have an effect on radio waves likeĪ torchlight on light. (known good) antenna to it if you have one available. Also inspect the connecting cable, or try to connect another The antenna has no effect, improve the alignment between the antennae on the Access PointĪnd the client. Signal strength with and without an antenna connected to your Wifi client. Signal strength with and without antenna Simply start it up, and select the reference APįrom the list by double-clicking on it. Simply read the value from the "Signal Strength" If you use the utility software, connect your client "Antennekabel los" means disconnected antenna cable "Antenne roteren - Richteffect" means Rotate antenna - Directionality "Antenne roteren - Polarisatie" means Rotate antenna. Make use of the Signal Strength indication in the utility software You can choose either one of both options that follow Used as a signal source, using its standard antenna. In the following description, I assume that the AUT isĬonnected to the Wifi client, as shown in the picture above. Somebody else's network, just as long as you have an idea about the physical You may use an Access Point that is part of 10 to 20 meterīest results are obtained with measurements in free space. Than an intermittent contact during measurement.įigure: Senao NL-2511CD plus Ext 2 PCMCIA card and a biloop antennaįor a reliable measurement you must get a descentĭistance between the antennas of the Access Point and Client. This minimises the effect of the coaxial cable on the measurement The cable must be suitable for the frequency and should have the lowest The Antenna Under Test to either an Access Point or Wifi Client to test it.Ĭonnect the antenna with a minimal length of coaxialĬable. The same in both directions transmitting and receiving. The Antenna Under Test (AUT) can beĪccess Point (or wireless router, as a transmit-antenna) or to the client (as receiving-antenna).Īntenna parameters have reciprocity – This means that an antennas parameters are You will need an Access Point as an RF Signal generator and ![]() Sadly you will need more specialised equipment. Perform to establish if an antenna behaves as an antenna, or an elaborateįor the method described here, we make use of standard Radio LANĮquipment to assess your homebrew antenna. Not everyone has measurement equipment for testingĢ.4GHz antennas laying around -) There are however some simple tests you can Wifi antennas - Without the use of special equipment. Successfully completed your homebrew antenna project!Īfter all this effort, you are left with only one question: Was it worth theĮffort? Does the antenna life up to your expectations?
