Wireless keyboards come in all shapes and sizes. Some are great for gaming, while others are meant to work with tablets,desktop computer and phones on the go. It’s best to think about why you need a wireless keyboard along with what types of features you’re looking for before buying one.

What Will You Use Your Keyboard For?

Not all keyboards are created equal. To find the best keyboard, consider what you’ll primarily be using your wireless keyboard for. Here are a few common use cases:

• At Your Desk: If you plan to keep a wireless keyboard at your desk, then you should probably focus on ergonomics and style. You may also want to look at extra features like RGB lighting or Built-in tray for tablet and phone…
• On the Go: If you need a wireless keyboard for use with your tablet or laptop, no matter where you go, you should focus on slim form factors. You may even consider a tablet keyboard case.
• From the Couch: Smart TVs or media centers hooked up to computers practically need a wireless keyboard. In this case, we suggest using a wireless keyboard with a built-in trackpad.
• For Gaming: Most PC gamers use a mechanical keyboard, sometimes with programmable keys and RGB customization.

1/The Basics: Keyboard and Connection Type

There are two main keyboard types: membrane and mechanical. Though it may not seem it, they are quite different from one another, and the form that you decide on will dictate what specific kind of keyboard you can buy (a portable keyboard, an ergonomic keyboard, etc.).

Here are some of the qualities of membrane and mechanical keyboards:

• Membrane: Most modern keyboards are membrane keyboards. They’re slim and quiet. In other words, they feel more like the buttons on your TV remote than the keys on a typewriter (but that’s not a bad thing—it’s more a matter of personal preference). These keyboards are best for general use and portability, and odds are, you’re using one right now.
• Mechanical: Mechanical keyboards, on the other hand, are modeled on the loud chunky keyboards of yesteryear. They provide a lot of physical feedback, and they’re easy to type fast on, but they also make loud clicking sounds. Mechanical keyboards have removable keys (so they can be cleaned and customized) and are most popular among gamers and computer nerds. They tend to have a better lifespan than membrane keyboards but, because of this, they’re typically more expensive as well.

2/Think About Ergonomics

People assume that ergonomics only matters if you spend all day at the computer, but that’s not entirely true. An ergonomic keyboard forces you to maintain your posture, which is essential for any typing session—even if it’s a short one.

 Let’s begin with non-ergonomic and work our way up to those with full-on ergonomic designs:

• Flat Keyboards: Some keyboards lay flat on the tablet. This design tends to put a lot of strain on your wrists and makes typing more difficult. Unless you’re committed to a tablet keyboard case or a portable keyboard, we suggest avoiding flat keyboards if ergonomics are important to you.
• Slanted Keyboards: Most keyboards are slightly tilted or have built-in kickstands. A good slant is probably all you’ll need from a keyboard, even if you spend all day typing (provided you can keep your wrists straight).
• Wrist Rests: A keyboard with built-in wrist rests can help keep your wrists straight throughout the day. Of course, you can also buy separate wrist rests to go with any keyboard.
• All-In Ergonomic: Super-ergonomic keyboards often look ridiculous (though the designs are always improving), but they force you to use great posture. These keyboards are great for people who type all day, people who have bad wrist posture, or people who really want to avoid wrist problems.

3/Additional Design Options

let’s start with portable features. These features make keyboards easier to take away from home, which is great if you’re using a laptop or a tablet (keep in min:

• Slim Keyboards: Ultra-slim membrane keyboards are great for on-the-go use. You can also buy a portable mechanical keyboard for when you want to type as loud as possible in public.
• Tablet Keyboards: You can use just about any Bluetooth keyboard with a tablet, but we suggest using a keyboard case or a keyboard with a tablet kickstand.
• Foldables and Rollables: Foldable and rollable keyboards seem a bit gimmicky, but they’re extremely portable.

4/Special Features

These features aren’t always necessary, but they can make a bit easier or add more fun to work with:

• Multi-Device Keyboards: Some keyboards are able to quick-switch between devices at the push of a button.
• Couch Keyboards: Some wireless keyboards have built-in touchpads. These are most useful for portable laptop or tablet setups, but they’re also great for smart TVs or media centers (like a computer hooked up to your TV), as they mean you won’t have to keep a mouse connected as well.
• Backlights and RGB: Backlights can add a fun, futuristic touch to your keyboard (and help you type in the dark). And, of course, RBG-enabled keyboards can be customized to match the color of your entire computer rig or your room’s color scheme.

A membrane keyboard is a cheaper alternative to mechanical keyboards. It has a protective layer of plastic or silicone that protects it from gathering food crumbs and dirt between the keys. Plus, they do not make that irritating clicking sound every time you press a key.  

How Does a Membrane Keyboard Work?

A membrane keyboard is a flat surface of keys. Under this flat layer, there is an integrated circuit system. When you tap on a key, the electric circuitry is activated, and the signal is sent to the processor. As a result, you see the characters displayed on your screen.

Features of a Membrane Keyboard 

Do you want a short description of a membrane keyboard? Here are the main features of a membrane keyboard:

• They are inexpensive offering reliable quality. 
• They are flexible and have a thin layer of keys.
• They are easily portable–easy to carry around and smaller in size–lightweight.
• A protective layer is present over the key to prevent dust buildups.
• They do not create a clicking sound upon pressing the keys,no typing sound upon clicking the keys

A high-quality membrane keyboard can be great for users who prefer a lightweight, portable, and quiet keyboard for their systems. Many shared office spaces often go with this choice. 

In terms of product labeling and marketing though, something called ‘wireless’ (with no mention of Bluetooth) is most likely using a wireless dongle of some sort. 

• Wireless keyboards that connect to a USB receiver, can only connect to a computer via a USB port.
• Bluetooth connectivity does not require a receiver, and can connect to a Bluetooth-enabled device without any ports.

There are a few general advantages to USB Dongle:

• It will work with any device that can take the dongle (in this case, anything with a USB   port). That is to say, devices that have USB but not Bluetooth can use this.
• Generally, you can get a higher polling rate and/or use less power.
• The pairing process tends to be a lot simpler- usually you just plug it in and turn the device on.
• Devices that use this tech are generally cheaper.

Bluetooth has the advantage that it can be paired with anything that has Bluetooth support (which is most mobile devices these days) and does not need any additional hardware. As a corollary to this, you don’t use up a USB port with the dongle. For some devices that have very few ports, this can be a pretty major plus.

Keyboards are input devices. An input device is any peripheral or computer hardware that’s used to control signals to your computer. Mice, keyboards, scanners and even gaming controllers are all considered input devices or peripherals.

Keyboards are divided into two main categories based on input method. These categories are:

• Wired keyboards
• Wireless keyboards

Wired Keyboards

A wired keyboard means there is a wire connecting your keyboard to your computer. At the end of the wire is a USB plug that goes into a USB port on your computer. Wired keyboards are extremely reliable—there is little that could go wrong with this direct connection.

The one drawback to having a wired keyboard is that your distance is limited between the keyboard and your computer; you can only have your keyboard as far from your desktop or laptop as the wire length. Also, wires will clutter your desktop. If you are looking for something sleek, you might consider a wireless keyboard.

Wireless Keyboards

A wireless keyboard works just like a wireless mouse; you plug a receiver into one of the USB ports on your computer. The receiver then sends a signal to your battery-powered keyboard. Keep in mind, wireless USB keyboards do have a limited range and some must be within the line of sight of your receiver, depending on the type of signal it uses. Also, if your cordless keyboard starts acting sluggish, it probably requires new batteries or recharge your built-in lithium batteries.

Wireless keyboards present a specific benefit to the consumer. First, wireless USB keyboards reduce wire-clutter on your desk. Also, you aren’t tied to your desk—you can type from your couch, your kitchen table or even while seated on your living room floor!

If you’re thinking of getting a wireless keyboard, the question of how it works is something that must have come to your mind. Well, the wireless keyboard works through different ways to connect it to your computer, and these include the following.

• Through Bluetooth connections.
• Through radio frequency (RF).

Each technology is equally effective in connecting the wireless keyboard to your computer.

Deep Dive: How Wireless Keyboards Work

Wireless keyboards work by wirelessly transmitting data to the computer through a Universal Serial Bus (USB) that acts as the receiver of the keyboard signals. Irrespective of the signal used, there must be a plugged-in or in-built receiver that communicates with your computer for the wireless keyboard to work. 

The computer must also have an Integrated Circuit (IC) chip that receives all the wireless keyboard’s signals. This information is then transited to your computer’s Operating System (OS). Subsequently, your computer’s Central Processing Unit (CPU) processes and deciphers this encrypted data from the wireless keyboard. 

But for wireless keyboards to work, they must have batteries or an AC power connection to power them. Here’s a look at how each of these technologies works.

Method #1: Through Radio Frequency (RF)

Wireless keyboards that work by transiting radio signals do this thanks to a radio transmitter positioned inside one of the two tiny enclosures inside the keyboard. The transmitter can be placed on one end of the keyboard and below a plastic window at the top. However, moving your fingers between the keys doesn’t offer you greater mobility. 

The other design is where the RF transmitter is positioned directly below each key. Regardless of the RF transmitter’s position, the wireless keyboard transits electrical current via the switch’s metal contact. This then closes the circuit and transmits a radio signal to your computer. The wireless keyboard also features a microchip that stores the code for each key. 

Once your computer obtains the code, it deciphers it quickly and sends a corresponding number or letter to the program currently running. The radio frequency method of transmission is preferred because it offers a greater range, usually spanning distances that reach up to 100 feet. 

Method #2: Through Bluetooth Connections

Another popular method that wireless keyboards convey data to the computer is through Bluetooth technology. This technology is especially ideal because it doesn’t require a direct line of sight to establish a connection. It also provides for high data transfer speeds. This makes Bluetooth connections ideal for workplaces due to their dependable connection. 

However, Bluetooth keyboards have one major downside: they sometimes aren’t compatible with different Operating Systems or devices.  

Summary 

Using a wireless keyboard is an excellent addition to your workspace as it saves you the hassle of ensuring your workspace is well-organized. This keyboard also allows you to use your computer without necessarily being too close to it, which is ideal for avoiding complications with your eye. 

But if you’ve wondered how the wireless keyboard works, this in-depth article has explained how this gadget links up with other devices. With this in mind, you’re now better placed to understand how this technology works besides enjoying how it allows you to work efficiently and comfortably.
