How to Choose The Right Wireless Hardware

When choosing wireless network hardware for your newly calculator, the choices available can sometimes be overwhelming. not alone must you choose the right card, but you need to ensure you have the right antenna for your needs. The specific card and antenna combination necessary will broadly be based on 3 key factors : what you will be using the network-connected device for, what kind of radio receiver network you are connecting to and how far away you are from the source signal. If you know the answers to these basic questions, choosing the right network solution can be fairly easy.

Selecting a Wireless Card

Compatibility with Computer and OS

Intel 7260 AC Wireless PCIe Mini Card The first step in choosing a radio receiver card is making indisputable it is compatible with your calculator and operate on system. Most radio cards plug into Mini PCIe and M.2 Key-E for Wi-Fi or M.2 Key-B for Cellular connectivity. If your calculator has this slot then the calling card will be electromechanically compatible. Most cards today are PCIe based, so ensure you ’ ra buy a circuit board and motherboard that has the correspond connection s required. Some cards use PCIe for the Wi-Fi and the USB for Bluetooth connectivity, therefore when choosing a card that supports both, be sure the slot you are inserting it to supports both PCIe and USB signaling. future, you must make certain there are drivers available for that card and the operate organization you plan to use ( Windows for example ). At OnLogic, we make sure to choose cards that have a wide range of compatibility, with most of our radio cards support both Linux and Windows operating systems .

Compatibility with Network

once you know the tease will work with your calculator, you need to ensure it ’ s right for the kind of network you ’ ll be connecting to. Wi-Fi cards are broken toss off to the engineering they have, for example, the newest cards feature W-Fi 6. The bequest terms for radio network cards are broken down into different variants, represented by 802.11 ( an IEEE stipulation ) followed by a letter ( mho ). For model, the modern radio receiver standard is 802.11ax ( now known as Wi-Fi 6 ). previous versions included “ b-complex vitamin ”, ” gigabyte ”, ” n ” and “ a ”. Except for “ a ”, wireless networks are cross compatible, meaning a “ gigabyte ” enabled card can connect to an “ normality ” network ( provided that officiate is not disabled by your router or IT team ). however, if you want the full bandwidth and features of the newest networks, you need a match radio poster. Wi-Fi naming has recently been updated to define the genesis. presently the newest generation is Wi-Fi 6 which corresponds to the IEEE definition of 802.11ax. You can find the newest generations of Wi-Fi and what they primitively were called on the Wi-FI alliance web site : hypertext transfer protocol : // besides important for some customers is the post of the chipset running the card. Examples of these include Intel, Broadcom and Qualcomm Atheros. The manufacturer of the card doesn ’ t necessarily indicate specific features, many times it comes down to experience and personal predilection and what your application requires .


The last thing to check is if the card includes Bluetooth onboard. Although most modern radio receiver cards come with it, some still don ’ thyroxine. Bluetooth is great for connecting radio receiver peripherals and other devices to your computer. Like Wi-Fi, Bluetooth has multiple versions available, with the most current version being 5.2. Bluetooth is besides backwards compatible, meaning all versions can interconnect with each other. however, as with radio internet, you lose some features doing this.

Which Wireless Antenna Do I Need?

With antennas, there are two pieces involved ; a pigtail cable which goes from the inner wireless batting order to the exterior of the chassis, and the actual antenna. When you add radio hardware to any Logic Supply system, the pigtail is included by nonpayment. What international relations and security network ’ metric ton included, and what you ’ ll need to choose, is the external antenna. One of the most important antenna specification to consider is profit. Gain refers to how well the antenna amplifies the signal it ’ s receiving. This is measured in decibels ( decibel ). The higher the decibel, the better the antenna will perform in strengthening weak signals. The typical image for screw-on antenna is 2-7dB .

Single Band vs Dual Band Antennas

Antennas are besides classified by what frequency bands they are tuned to amplify. Any radio receiver engineering has a frequency band that it needs to operate within. Bluetooth operates in the 2.4Ghz band, as do legacy Wireless networks. Wi-Fi 4 and beyond may besides operate in the 5Ghz band. When buying an antenna, you need to ensure these bands are covered. At OnLogic we sell unmarried ring and double band versions of our antenna. Single ring covers just 2.4Ghz while a dual isthmus antenna covers 2.4Ghz and 5Ghz bands. The well news with frequencies is that they don ’ thyroxine change. That means your IT department or router can ’ t unwittingly choose to operate outside of those two bands. One interrogate we get much is, if Bluetooth and Wireless are operating in the same frequency range, won ’ thyroxine they interfere ? This is a big question, but in world, the two aren ’ t actually operating at the exact lapp frequencies. actually, the 2.4Ghz range has several break frequency bands or channels that devices can use, and many devices dynamically change channels to help prevent intervention and increase operation. A 2.4Ghz antenna can cover all of these frequencies, known as channels. additionally Wi-Fi 6 introduces OFDMA ( Orthogonal Frequency Division Multiple Access ) where a specific distribution channel can split the bandwidth evenly across up to 30 users without expecting intervention. This is capital in applications where many users are crowded in one area and don ’ t necessarily need all of the distribution channel ’ mho bandwidth .

What Size Antenna, and How Many?

so, what about the physical size of the antenna ? You ’ ll want to make sure that the size of the antenna works in the footprint in which the calculator will be operating. Size doesn ’ triiodothyronine necessarily affect the performance of the antenna, so always check the dubnium rat of the antenna you choose.

The survive thing to consider when selecting antennas is deciding how many you need. Generally talk, wireless cards have two antenna connections and you should use both. Although it is possible to get away with one antenna if the router or signal source is close up enough, you should normally stick to the number of antennas recommended by the batting order manufacturer. Choosing the right wireless solution can be slowly when following the above guidelines, and knowing your custom position goes a long way to ensuring you choose the ideal hardware. If you have questions about which radio card and antenna combination would best become your needs, call OnLogic ’ s highly capable technical team who will cursorily identify the proper radio solution for your singular undertaking. note : This web log was originally posted on February 17, 2015.
