In the current world which is highly digital, uninterrupted WiFi access is a must for every individual in both their private and business lives. The range of different devices that have already been dubbed ‘smart’ is in the hundreds and the robust and extensive WiFi network needed to fit them all is the main feature of the Internet connection today. Using a dual band WiFi repeater is one of the ways to fulfill that need. The following review will guide the reader through the different aspects of a dual band WiFi repeater; operation, pros and cons, setup and configuration policy, and comparing it with other network solutions.
Dual Band WiFi Definition
Before discussing dual band WiFi repeater, there is no way around defining dual band WiFi. Typically, Wi-Fi networks work on two frequency bands: the 2.4 GHz and the 5 GHz ones.
2.4 GHz Band
Range: The 2.4 GHz band has better penetration through walls and obstacles than the 5 GHz band and thus it has a longer range.
Speed: It gives slow speeds, which are usually enough only for simple operations like web surfing and email.
Interference: The interference in this band is relatively high since the band is also shared with other devices like microwaves, cordless phones, and baby monitors.
5 GHz Band
Range: The 5 GHz band has a shorter range and is less effective at penetrating walls and obstacles.
Speed: It offers higher speeds, suitable for bandwidth-intensive activities like HD video streaming and online gaming.
Interference: It is less congested and experiences less interference compared to the 2.4 GHz band.
What is a Dual Band WiFi Repeater, anyway?
A dual band WiFi repeater is a device each making the coverage area of an existing WiFi network larger and at the same time supplying the network with both the bands 2.4GHz and 5GHz signal by going through the primary router. A repeater called this way can work with more than one frequency band at once, thus, it gives better performance and flexibility in use compared to a single band repeater.
How It Works
Signal Reception: The dual band repeater catches WiFi signals coming from the primary router in two bands—2.4 GHz and 5 GHz.
Signal Processing: It then filters out these signals and makes them retransmission ready.
Signal Rebroadcasting: The repeater just goes on with the signals as it was before and not only that but enlarging the area of the network.
Since the dual band repeater operates on two bands the overall throughput is higher and the interference is also reduced which leads to the WiFi connection being more reliable and faster.
Benefits of Dual Band WiFi Repeaters
Repeating devices working on two bands at once give an advantage over the others making it a more desirable choice to cover WiFi signal:
Enhanced Performance
A dual band repeater’s main benefit is improved performance. This is because it can reach out to both the 2.4 GHz and 5 GHz bands. Hence, their ability to support heavy traffic along with getting faster overall speeds are among the best features of these repeaters. This is especially useful with high bandwidth requirements in a multiple device environment.
Less Interference
The 5 GHz band is pretty much empty compared to the 2.4 GHz one, hence it goes through significantly less interference. Therefore, if dual band repeaters were to work on both bands they would ultimately reduce interference problems and result in a very stable and thus a very reliable connection.
Enhanced Flexibility
Dual band repeaters have made network management to be more flexible than before. The users can assign different types of traffic to different bands as per their preference. For instance, applications requiring a lot of bandwidth such as video streaming can be routed to the 5 GHz band while internet surfing can go on the 2.4 GHz band without any disturbance.
Future-Proofing
The ever-increasing demand for bandwidth by devices and applications can be met without having to upgrade your network if you have a dual band repeater. This guarantees that your network will not only cope with the higher demands but also be able to work with the new Wi-Fi 5 devices that support the 5 GHz band.
Disadvantages of Dual Band WiFi Repeaters
Dual band WiFi repeaters have disadvantages as well, despite their benefits:
Complexity in Setup
A dual band WiFi repeater installation might fall under the more complicated side compared to that of a single band repeater. The users have to set up both 2.4 GHz and 5 GHz bands which can be a little overwhelming for people who don’t have a strong technical background.
Reduction of Bandwidth
Similar to all WiFi extenders, dual band repeaters might also face the problem of reduced bandwidth. The situation of the repeater having to receive and transmit the signals simultaneously contributes to halving the total usable bandwidth; hence, performance getting adversely affected especially where the application is of that kind high.
Price
Dual band repeaters are normally priced higher than their single band counterparts. The added technology plus features dictate the higher cost that might not be very keenly looked upon by users with tight budgets.
Position Sensitivity
Dual band repeaters are highly placement dependent. They must be and feed off the strongest source signal of the main router in order to transmit and receive the signals properly and still be allowing air into the signal. Bad placements could yield faint signals and thus, underperformance.
Installation of a Dual Band WiFi Repeater
To install a dual band WiFi repeater there will be different manufacturer and model specific steps to follow, but generally, it is going to be a series of simple steps depicted in the following guide:
Guide to Installation Steps
Preliminary Setup:
Setup the repeater in a spot that is within range of the primary router signal. Power it on, and then either connect it to your computer through Ethernet or WiFi for initial configuration.
Entering the Repeater Web Interface:
Launch a web browser and put in the repeater IP address (normally is mentioned in the user manual or even on the device). This will send you to the login panel of the repeater web interface.
To Log in:
Input the admin username and password for the repeater to log in. The defaults are typically “admin” for both username and password if you have never changed them.
Select Dual Band Mode:
On the web interface of the repeater, look for the wireless settings or a certain repeater mode option. The dual band mode should be the selected option.
Configure 2.4 GHz Band:
Among the networks available, select the 2.4 GHz one that you want to extend. Enter the password of the primary router’s 2.4 GHz network so that you can connect the repeater to it.
Configure 5 GHz Band:
The desired 5 GHz network to be extended should be picked. The password for the primary router’s 5 GHz network should then be entered so that the repeater can be connected to it.
Additional Settings:
You can configure any additional settings such as SSID (network name) for the extended networks and security types. It is possible to either use the same SSID as the primary network for seamless roaming or create different SSIDs for the extended networks.
Save and Reboot:
The repeater will reboot after you have saved your changes. The device will be ready to work in dual-band repeater mode, thus enlarging the coverage of both 2.4 GHz and 5 GHz networks after it cools down.
Advanced Configuration Options
With the advanced configuration options, the users can take a closer look and adjust the performance of a dual-band Wi-Fi repeater. These settings can not only be a great help when it comes to overcoming some of the disadvantages but also in tailoring the network to specific needs.
Channel Selection
Selecting the appropriate WiFi channel can greatly limit the interference caused by the networks around you. Analyze the wireless environment using tools or apps and choose the channels that are the least busy for both the 2.4 GHz and the 5 GHz bands.
Band Steering
Band steering is a feature offered by some dual band repeaters which automatically assigns devices to the best band taking into consideration their eligibility and the conditions of the network at that moment. The load can thus be balanced, and network performance can be enhanced overall.
Network Name (SSID) Configuration
Make up your mind if you want to use the main network’s SSID or not. The use of the same SSID makes it possible to roam freely between the main router and the repeater without any registration, whereas, different SSIDs can effectively control which devices are connected to which segment of the network.
Security Settings
To keep the network secure at all times, make sure the repeater is set with the same security protocols (for instance, WPA3) as the primary router. Also, consider the option of guest networks for the repeater if it comes with that feature.
Quality of Service (QoS)
QoS settings give you the control to designate particular types of traffic to be given priority, thus making sure that highly needed applications such as video calls or online gaming are allocated sufficient bandwidth.
