What is 2.4 ghz wifi?

2.4 ghz WiFi is a wireless network technology that uses the 2.4 gigahertz (GHz) radio frequency to communicate with devices. It is the most common form of WiFi, and is used in homes, offices, and public hotspots to connect devices to the Internet.

What's a Dual Band Router?

A dual-band router is a network router capable of simultaneously emitting wireless signals over two separate frequency bands. The most common dual-band router is a 2.4 GHz and 5 GHz router. These offer support for the older 2.4 GHz band and the newer, faster 5 GHz band without deterioration in performance. It allows you to take advantage of the benefits of both frequencies and get the best possible speed for your devices. Dual-band routers are also called dual-band Wi Fi or dual-frequency Wi Fi.

The advantage of using a dual-band router is that it can provide greater bandwidth and faster speed with reduced interference than a single-band router. Dual-band routers are ideal for homes or offices with multiple wireless devices that need to be connected to the Internet, such as laptops, printers, tablets, smart wearables, smart appliances, and smartphones.

Features of the 2.4 GHz Frequency Band

The 2.4 GHz frequency band spans a frequency range from 2.4 to just under 2.5 GHz and is the most commonly used frequency for wireless networks. Its key features include-

  1. Non-overlapping channels- Though there are 11 channels available in 2.4GHz, only three do not interfere or overlap with others- 1, 6, and 11. By bonding these channels, multiple-input multiple-output (MIMO) systems can offer a wider communication pipe and greater capacity.
  2. Greater range- The 2.4 GHz band transmits strong signals over large spaces that can travel up to several kilometers due to their relatively long wavelength. Its longer range makes it more suitable for large offices and homes. If you move away from the router, the network's quality remains almost the same. This makes the 2.4 GHz band well suited for point-to-point link applications such as outdoor Wi Fi hotspots.
  3. More compatible- Many devices support the 2.4 GHz band, making it more compatible with a wider range of internet devices. It is one of the most popular frequency bands for wireless applications.
  4. Low interference from other devices- Many common household devices operate in or near the 2.4 GHz frequency band, including microwave ovens, cordless phones, and Bluetooth devices. However, due to the relatively narrow bandwidths used by these devices (usually 1MHz or less), they generally do not cause significant interference to Wi Fi networks operating in the 2.4 GHz band.
  5. No need for license- 2.4 GHz is the upper limit of the unlicensed ISM (Industrial, Scientific, and Medical) band, and anyone can use it without prior authorization from the authorities. The 2.4 GHz band is still a good choice for networking due to its wide availability and low cost.

Features of the 5 GHz Frequency Band

The 5 GHz frequency band is another popular electromagnetic spectrum for wireless communication and is denoted as super-high frequency (SHF). Frequencies in the 5 GHz band range from 5.15 GHz to 5.85 GHz. As its wavelength is measurable in centimeters, it is also called a centimeter band. Its features include-

  1. More available channels- The 5 GHz band offers 24 non-overlapping 20 MHz channels, which reduces interference and improves performance. In addition, wider channels mean that it can support more data bandwidth-intensive applications such as streaming HD audio/video content, online gaming, video conferencing, etc.
  2. Less congestion- The 5 GHz band is not as crowded as the 2.4 GHz band. Since fewer devices are equipped with features that allow them to operate on this band, it is faster and less prone to traffic.
  3. Greater speed and capacity- The 5 GHz frequency band has a higher frequency and a lower wavelength. In addition, channel bonding can increase channel size using multiple-input multiple-output (MIMO) technology; hence one can achieve much higher speeds on the 5 GHz band than on the 2.4 GHz band.
  4. Uninterrupted services- The 5 GHz band is less affected by other nearby devices and appliances. Hence, your internet speed and consistency remain uninterrupted.
  5. Greater penetration- 5 GHz has greatly increased scatter performance and is minimally absorbed by water, penetrating damp structures and objects.

How To Decide Which Frequency Your Business Requires

5 GHz frequency provides faster speeds at a shorter range than 2.4 GHz frequency, which travels farther at lower speeds. The frequency you choose should depend on where and how you use your Wi Fi connection. You will need to carefully consider your Business Wi-fi requirements and objectives before deciding which frequency suits your needs best. Some of the key factors to consider include-

  1. Deciding the right frequency for your business requirements is a process that begins with understanding your customers' buying habits. How often customers purchase your product or service, how often you need to communicate with them, and what budget you have for Wi Fi marketing. Once you know how often your customers purchase your product or visit your store, you can begin to tailor your communication frequency to match their needs.
  2. Another important factor is the Wifi Range you need to cover the size of your restaurant or building. If you have a large space, you will need a router that can broadcast on a higher frequency to reach all corners of that space.
  3. Then, it's time to consider the number of devices using the Wi Fi at one time and the activity level on your premises. If you have many people working close to each other, you'll want a router with a higher frequency so that it can handle all of the traffic.
  4. The type of devices connecting to the Wi Fi network also needs consideration. Some devices, such as laptops and smartphones, can connect to both, 2.4 GHz and 5 GHz networks, while others, such as older laptop models and some printers, can only connect to 2.4 GHz networks.
If you're still unsure which frequency would be best for your business, it's always a good idea to start with a lower frequency and then increase it if needed.

How To Change Wifi Frequencies

To change the Wi Fi frequency, the initial step is to go into your router's admin page. From here, you'll be able to change various settings, including the Wi Fi frequency. Ensure your router is compatible and has the right frequency capability for your specific model. Whether you choose a 2.4 GHz or 5 GHz Wi Fi connection, ascertain that the wireless option is enabled on your modem/router and set it to the same frequency.

Then, look for the section labeled, Wireless. Select the option that says- Channel and SSID. Next, you will be prompted with a drop-down menu to select the different Wi Fi frequencies. Choose the one that you want and then press Save.

In the case of a dual band router, you have two networks (SSIDs) that appear in your network list with identical names, except for a "2.4G" or "5G", at the end of it. Now, you can connect all your internet-enabled devices individually to any of these Wi Fi networks. A dual-band router changes its setting to transmit at both frequency signals simultaneously.

Modern modems also allow you to choose the best Wi Fi channel for your environment and change it as necessary through the wireless settings. You can then utilize both, 2.4GHz and 5GHz Wi-Fi's capabilities to the optimum. However, it is always better to know that changing frequencies can sometimes cause interference with other devices on the premises, so it's not always the best solution.
