To understand the mechanism behind wireless Internet cards, you first have to grasp how the wireless Internet itself works. When USB wireless adapters first hit the market most of them did not have an external antenna. Dual Wi-Fi antennas operate on a principle known as antenna diversity, which offers two different reference points for signal reception or transmission (or both) and uses the better one. I bought a new PC a few days ago and noticed it came with two wifi antennas for the card. This is not something that you have to worry about with a PCI-E WiFi adapter. Hey PCMR, My wifi card has 2 antennas while my router only has 1 antenna pointing upwards (vertical). I ordered the WIFi Card and antenna as specified (about $30 USD total on eBay with free shipping). When integrating wireless hardware with your embedded computer, the pigtail is included by default. If the additional antenna actually makes a big difference in speed, I'd go with that one, but if doesn't, why not save the money, right? Further, focus groups show that people prefer not to have external antennas, for aesthetic reasons. ... which is why many wifi tips guides recommend switching away from it to boost speed and reliability—it’s just less congested.

Risk mitigation is a strategy to prepare for and lessen the effects of threats faced by a business. So at this point, you may be thinking “why should I bother even considering a PCI-E WiFi adapter if the USB solution is so much easier to install and setup?” I had the same thoughts but there are advantages and disadvantages to both of these types of WiFi adapters. 2 comments. John Dorsey and Douglas Kough invented an antenna diversity system that has been patented by Apple. Based on the Antenna placement, there are mainly two types of WiFi Antennas. dual Wi-Fi antenna: A dual Wi-Fi antenna is a pair of identical antennas on a wireless router or Wi-Fi -equipped device, intended to eliminate signal fading and dead spots. This antenna has a 1 metre lead. When I did this I had to make the decision between using a PCI-E WiFi card in my desktop computer or using a USB WiFi adapter which seemed to be a lot less hassle to me. The only real disadvantages of a PCI-E wireless adapter are that you have to physically install them into your computer and they are often more expensive than a USB wireless adapter. Adding a 2nd antenna would require complete disassembly of the notebook, including the display panel area, in order to properly route the antenna. Dual Wi-Fi antennas operate on a principle known as antenna diversity, which offers two different reference points for signal reception or transmission (or both) and uses the better one. This means that you should be able to pick up a stronger signal from your WiFi router. Because a router’s antennas are physically located different places on the device, they each receive a sliiiiiightly different version of the signals sent by connected clients. The signal arriving at the receiving end of the circuit therefore comprises several different component waves that rarely, if ever, perfectly reinforce each other. Multiple antennas are typically used in a MIMO (Multiple-In-Multiple-Out) configuration, but can also just be for plain antenna diversity. To understand the mechanism behind wireless Internet cards, you first have to grasp how the wireless Internet itself works. Think of it this way.

Wi-fi cards that support using two antennas generally have an internal switch that will select one antenna or the other. You also have the option to opt-out of these cookies. An Intel wireless card most likely will not work in your notebook because it has AMD hardware, so that is why I don't recommend you risk getting an Intel card on a 90% probability it won't work, where there is a 100% probability the Broadcom cards will--as long as your notebook has 2 antennas to connect to the card. I want to hook my desktop computer into my home wireless network and have found the PCI card option to be relatively easy and inexpensive. This is called spacial diversity and it helps to improve link reliability. This means that you should be able to pick up a stronger signal from your WiFi router. You do not have to install anything and never need to take the cover off of your computer. This is called diversity, and it is used to counter issues with channel fading. In severe cases, a drop-out (and consequently a lost connection) can occur even if the user moves by only a few centimeters, or changes the angle in which the device is held. Devices in a WiFi network are connected together wirelessly for the purpose of sharing resources and information. It is just simply a matter of plugging the USB WiFi adapter into a spare USB slot in your computer. The purpose of that MIMO antenna is to transmit and receive data along more than one spatial path. These days, you can find USB wireless adapters that have an external antenna. When I first looked at these two options I thought to myself “well they do the same job don’t they so why bother researching this any further?” I am a curious person by nature and I just couldn’t help myself. This Laptop has a separate opening just for WIFi card and RAM. I mean what could be simpler?
