What is the Difference between Bluetooth and 2.4 GHz?

Do you need clarification about the difference between Bluetooth and 2.4GHz? Why do some keyboards and mice come with a USB dongle while others connect to the computer without it? These two technologies have many differences in operation and connectivity. One is good for gaming, while the other is ideal for office work or creativity.

This article will explore the differences between BT and 2.4GHz technology. The primary goal is to ensure that the reader is well aware of all the advantages of each technology to make the best purchase decision.

1. What is Bluetooth?

Bluetooth came into existence as an alternative to wired technology in 1998. The Bluetooth Special Interest Group oversees all its standards and licensing issues of the technology. Every Bluetooth device aims to provide a low-power, decent-range wireless device that works cross-platform.

Bluetooth is everywhere, from mobile devices, headsets, remote controllers, gaming consoles, and televisions to server PCs. This low-power communication protocol's wide-scale application goes through every tech-enthusiast sight.

It works between the license-free ISM band 2.402 GHz to 2.480 GHz and comes in three classes: 1,2, and 3. Each one works at different power levels, which affects its operating range. Manufacturers decide which Bluetooth class is suitable for a device considering the aspects in the table below.

The technology of Bluetooth has evolved rapidly. Ericsson, IBM, Intel, Nokia, Toshiba, or the Bluetooth SIG group has actively taken the BT from substandard audio, low transmission range, and high latency to a high performance, highly feasible feature of every mobile device. Look at the table below to understand how the technology has evolved in data transfer speed, range, and features.

2. What are the key features of Bluetooth?

To understand the advancement in BT technology, let's have a look at some of its latest features and how they contribute to better communication:

● BLE: The succession of the older LE technology contributes to longer battery life and lower power consumption.

● BR/EDR: Bluetooth Basic Rate/Enhanced Data Rate is a mode with high transfer rates but also leads to increased power consumption.

● LE Audio: Although manufacturers are not massively adopting the technology, it is the low-energy audio transmission technology for device-to-device audio.

● Direction Finding: Tracking was not possible in earlier versions. The BT5 onwards makes it possible to find the direction of a device.

● LC3: Low Complexity Communication Codec. It targets audio devices that require audio compression for delivery. The older SBC codec requires a data transfer rate for operation, whereas the new LC3 involves half of the SBC requirement. It leads to better performance.

3. What is 2.4GHz?

If you're into video gaming or cutting-edge technology, you've probably heard about 2.4GHz or RF gadgets. These devices take the lead regarding low latency and high performance. In contrast, the patented Bluetooth technology binds manufacturers to using limited protocols. Whereas in 2.4GHz, the unlimited possibilities allow tech companies to introduce stunning 1000Hz polling rates.

Any device with a high polling rate will communicate 1000 times per second with the receiver. The split-second decision to click and take a shot is critical for gamers. The device needs to register and properly execute the maneuver. 2.4 GHz diminishes the delay and latency issue with wireless devices. In contrast, Bluetooth communicates at a polling rate of approximately 125Hz, which is substantially lower.

The manufacturer develops the technology in-house. It leads to lower cost and high performance. If you are a gamer or an office worker with an empty USB port for a receiver, then 2.4GHz is an excellent choice.

4. Bluetooth vs. 2.4GHz, Which is better?

The table below provides a quick comparison of the two technologies.

5. Best Wireless Keyboard and Mouse Combo for Office Work

There are loads of devices available that come in a keyboard and mouse pair. We will mention two of the best gadgets that can add productivity to your work.

Logitech MK270

SPECS

Keyboard: Full-Size Rubber Dome

Mouse: Optical Ambidextrous

Battery: 2+1 AAA Batteries

Wireless Technology: 2.4GHz

The combo consists of a full-size keyboard with an ambidextrous mouse. It is suitable for left and right-handed personnel. The symmetrical and standard design makes it a good choice for office and school environments with the potential for multiple users.

The keyboard uses rubber dome technology, which keeps the product price low. To keep the device going, all it needs is three AAA batteries. The batteries can last around 36 months for the keyboard and 12 months for a mouse, with 2 million strokes per year.

MEETION MINI4000

SPECS

Keyboard: 75% Rubber Dome

Mouse: Optical Ambidextrous

Battery: 2+2 AA Batteries

Wireless Technology: 2.4GHz

If you want a combination of elegance and performance, then MEETION MINI4000 is the right product. It is a combo that consists of a keyboard and mouse. Its 75% white keyboard has a matt finish, making it fingerprint-resistant.

Anybody that uses wireless technology aims to have less clutter in their workspace. The limited space due to wire passing on the table and the large keyboard footprint reduce the minimalist look. MINI4000 exceeds expectations by lowering the keyboard size to minimize the device footprint and leaving space on the desk for office work.

The mouse also lives up to the standard by providing an ergonomic design that is friendly for right- and left-handed personnel. Both devices connect instantaneously to the computer with a nano-USB receiver. Connecting two devices leaves space for other peripheral connections. The product provides all the features without breaking the bank.

6. How to Choose the Best Wireless Technology for Your Needs

Picking between Bluetooth and 2.4GHz depends on the user's requirements and situation. If you are a streamer, creator, or music producer, you need every USB port on your computer. It's better to go for a Bluetooth device in that case. Bluetooth devices can also connect to television and gaming consoles, making the technology diverse.

2.4GHz, on the other hand, is budget-friendly with faster communication speeds, but it is rarely compatible with Android television and gaming consoles. The answer to the best device depends on the user. We recommend the MEETION MINI4000 as it has an ideal price/performance ratio, minimalist design, and durability. In addition, the Logitech MK270 is suitable for full-size keyboard users who require a numeric keypad.
