The internal mPciE WiFi cards in modern laptops come with at least two coaxial connectors for antennas, often labeled as "Main" and "AUX".Or just numbered: "1" and "2" on other cards. Laptops also have lots of metal around most WiFi cards... things like hard frames, batteries, hard drives and perhaps motherboards, etc... all impact WiFi signals and antenna patterns. I have a NUC8i5BEH and the wifi chip has two sockets to plug in the two dBi (Gain): signal strength of the antenna. Also better range due to dedicated external antennas. This is called diversity, and it is used to counter issues with channel fading. I found a wireless card utility, and the signal jumps from -60dBm to -30dBm when the external antenna is plugged in. dBi (Gain): signal strength of the antenna. By narrowing the path in which signal it let out, it allows for more range to be achieved.

The 2.4Ghz grid antenna is compatible with Wi-Fi standards 802.11b, 802.11g, 802.11n for fast data transfers up to 150 Mbps, and the 5GHz version uses the 802.11n/a/ac/ac2 standards with speeds up to 1.3 GBPS, and that parabolic grid is made of powder-coated cast aluminum, which makes it extraordinarily weather resistant. peetersorra I appreciate the helpful post award but I think GORT should have received it since what he said is what I said after his post.. Maybe there is a software setting for that, but I've never seen it. So was reading the answers of this question for the same problem that I faced with my Dell laptop. This sets up a standing wave, hence the term standing wave ratio (SWR) used in antenna matching. Because the transmitted signal is modulated over a carrier, it is technically an AC signal, which means that we refer to loads as being reactive instead of resistive. Wi-Fi card slots differ in size and shape in desktop computers and laptops. No, because you won’t find a compatible slot. Long Range WiFi Antennas. level 2. i5 4570, Intel Integrated. MIMO antennas let 802.11n products operate at much higher data rates by transmitting different data along different paths (recombined at the receiver). If you thought Wi-Fi couldn't get much faster than 802.11n, think again: 802.11ac, dubbed 5G Wi-Fi, promises ridiculously fast wireless connections, better range and improved reliability.

For more distance or when working with a known signal location, use a directional antenna. Most antennas can be removed from WiFi cards, making them easy to lose. The standing wave effectively resonates the properly tuned antenna much like a tuning fork resonates at its designed frequency of resonance, which causes electromagnetic waves to be radiated along the structure of the antenna. While a directional antenna acts in the same way a flashlight does. one question I would like to know is does my computer already have two antennas installed in the computer? The right antenna for the job depends on what function you need it to perform. I have seen some HP "home" desktop PCs with an internal wireless card, which was wired using very tiny coax cables to internal antennas located in the top plastic part of what was otherwise a metal case. I have a half-mini PCI-E WiFi card (RTL8192E to be exact), which has 2 small aerial pins plugged into it. If anything happens at all. As per dpaul, I understand that wireless devices do not need an antenna, so given a strong enough signal, any wireless "radiation" is able to reach the card. If you want to use a laptop WiFi card for a desktop PC, you’ll need to find a mini PCI to PCI or mini PCI-e to PCI-e adapter. I ordered the WIFi Card and antenna as specified (about $30 USD total on eBay with free shipping). More power is done by increasing the radio strength. The process also works in the opposite direction, with the card translating your computer's information into radio waves to send to the router, where it is put back into binary form and sent to the Internet over the wires. Requirements for using an M.2 WiFi card. You need a TV with antennae input (coax), or external TV tuner box. Laptop Wi-Fi cards come in different sizes, as do the card slots on your devices.

However because of signal reflections caused by the room and positioning of both, router and client you may see some difference when moving the antennas around. The higher the dBi, the further distance the signal will travel. As per dpaul, I understand that wireless devices do not need an antenna, so given a strong enough signal, any wireless "radiation" is able to reach the card. 0 A. Alabalcho Judicious. This is due to how narrow the beam is on antenna's like the Grid. To obtain maximum power transfer, the output impedance of the transceiver must closely match the input impedance of the antenna. They have much better capability to dissipate heat, packs better WiFi chipset. Raise your hand if you thought pointing both of a router's antennas straight up was better for Wi-Fi reception.
