Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/santanaservices/public_html/techiwarehouse.com/cms/engine.php on line 37

Antenna Power Gain

There are a lot of factors that determine the range of the connection of a wireless piece of equipment, but the main thing that affects it is the power gain of the antenna. Power gain is a numerical quantity and it is measured in dB, otherwise known as relative decibels. It stands for max effectiveness of one antenna in comparison to a different antenna. You will commonly see 2 standards that are being used by the companies who build them when they speak about measuring gain in antennas. They are dBd and dBi. The first one stands for decibels that are in relation with a antenna that is isotropic, and the second one stands for the same just for a dipole one.

It is more common to see dBi than dBd in wireless antennas. The standard measure for Dipole reference antennas are 2.14 dBi which is basically the same as zero dBd. If you see bigger number this means that that antenna which has that higher number has the possibility to work on larger numbers of power, and this most commonly translates into bigger signal range and strength.Wireless

Omnidirectional Wi-Fi Antennas

There are certain antennas that can operate with various signals that come from every possible direction. The most common thing where these will be found are wireless routers and adapters for mobile phones. In the common antenna that came straight out of the factory you will see a generic dipole antenna. They will most commonly be rubber ducks, this is a name for antennas that are coated with rubber. They are also commonly seen in walkie talkies.

Directional Wi-Fi Antennas

The gain of the antennas we mentioned in the previous paragraph is considerably lower because they can't focus their energy, they disperse it over a full circle. When you don't have to have a complete three hundred and sixty degree signal these one directional antennas are the standard thing to use. These one directional antennas are called Cantennas. There is a really strong type which has an addition to it's name, the Super Cantenna. It can support up to 2.4 GHz and has a gain of 12 dBi. It doesn't have a huge beam width, it is somewhere around thirty degrees.

Upgrading your wireless antennas

If you wish to decrease the rate of which problems in your Wi-Fi networks are create, the thing you are supposed to do is to upgrade you antenna to increase the strength of the networks signal. If you take into account a network that is located in a business, the usual thing is that those who work there are pros and that they will do thorough research to see and map the strength of the networks signal.

If you are seeking to upgrade an antenna in your home and speed up your own network, you should do these things.

There are some wireless devices that do not make it possible to upgrade your antenna after you have bought it. You should always see the documents that you got with the device to either confirm or disprove.

If you are looking to increase your overall signal in your home and make networking easier, upgrade your omnidirectional antenna.

You should take all factors in account when you are buying an antenna. Also, you can do what the pros do and map your network signal strength in your house.
