![]() ![]() ![]() Many of these antennas cost pretty much the same as standard routers, but they still give you the same speeds you’ve come to expect. ![]() Luckily, long-range Wi-Fi antennas help you keep moving around without losing out on internet access, no matter where you are in your house. While it’s reasonable that many of us sit just feet away from our router when it’s plugged in next to our sofa, users who frequently move around their house and away from their wireless source may experience difficulty connecting. Regardless of the scenario, you may need a Wi-Fi antenna that can do a better job than the one that came in the box from the cable company.Īs more and more workers have moved to an at-home environment instead of traditional office spaces, maintaining a solid connection is more important than ever. You may just need a few extra feet of coverage area, or you may need to get signal on an outbuilding miles away from your access point. We’ve all been there: the wireless network is working perfectly fine, and then you move a workstation into the back bedroom and find out that it has no signal, or you add a smart TV to your house and discover that the “up-to-300 feet” part of your router’s range description was optimistic at best. One of the biggest issues is when you run out of your networking area. The "sweet spot" on such ad hoc reflectors can readily be found by taping a small (~2.5 cm, or 1 in) mirror on the surface of the dish, to see where the sun's rays focus.If you’re working from home more often, you’ve probably experienced some network issues from time to time. The performance of abundant, low-powered Wi-Fi "dongles", typically selling for approximately US$15–20, but of only 30–40 mW transmitter power and modest receiver sensitivity, can easily be boosted with little more than cheap cookware or pot lids. Interference from nearby 2.4 GHz signals (perhaps from cordless phones, AV links, leaky microwave ovens, other APs or Bluetooth) can be nulled out-a useful feature in this increasingly crowded part of the RF spectrum. In addition, certain improved WokFi antennas, and antennas made using 60 to 90 cm (2-3 ft) diameter round or oval satellite TV dishes, allow even far greater range, up to 20 km (12 miles). Ranges (LoS) are typically 3–5 km (2 to 3 miles), although an aligned pair of similar point-to-point transceiver setups may approach 10 km (6 miles) over a clear path. WokFi gains are typically 10+ dB, with range boosts, thus can be 16-32 times over the antenna of a bare USB adapter. If using mesh reflectors, usually with a grid under 5 mm, the antenna will be lighter and present a smaller wind-load than larger dishes. Chaining active USB repeaters, it is possible to locate the antenna at much greater distances from the computer, which is especially useful when line-of-sight (LOS) obstacles (such as vegetation and walls) require the antenna to be located on a roof, for example. Therefore, by using standard USB extension cables, the antenna can be located at a distance from the computer of five meters or more, with no concerns over microwave signal losses that would occur in an RF coaxial cable feedline of that length used to attach a conventional antenna to the RF input of a computer modem. The WokFi antenna is considered simpler and cheaper than other home-built antenna projects (such as the popular cantenna), but is a very effective method to boost the Wi-Fi connection quality, audit access point coverage, and even quickly establish WLAN viability – perhaps if a more professional setup is eventually intended.Ī significant advantage is that with a USB modem the RF signal is converted to a conventional digital signal at the antenna. A commercial Wi-Fi antenna, usually a USB Wi-Fi dongle, is suspended in front of the dish, attached by cable to the computer. WokFi antennas are fabricated out of commonly available concave metal kitchen dishes or dish covers (which need not be perfectly parabolic) Asian woks are favored because they have shapes closest to parabolic. The dish forms a directional antenna which is pointed at the wireless access point antenna, allowing reception of the wireless signal at greater distances than standard omnidirectional Wi-Fi antennas. WokFi (a portmanteau derived from blending the words Wok + Wi-Fi) is a slang term for a style of homemade Wi-Fi antenna consisting of a crude parabolic antenna made with a low-cost Asian kitchen wok, spider skimmer or similar household metallic dish. ![]() JSTOR ( February 2022) ( Learn how and when to remove this template message).Unsourced material may be challenged and removed.
