Mikrotik WiFi: Channel Widths, CE, and EC Explained

Hey guys! Let's dive into the world of Mikrotik and unravel the mysteries surrounding WiFi channel widths, CE, and EC. Understanding these concepts is super important if you want to optimize your WiFi network for speed, stability, and overall performance. We'll break down everything in a way that's easy to grasp, even if you're not a networking guru.

Decoding WiFi Channel Widths on Mikrotik

Alright, let's start with channel widths. Think of your WiFi network like a highway. The wider the lane (or channel width), the more data can zoom through at once. In the context of Mikrotik, the channel width determines how much spectrum your WiFi signal occupies. It's measured in megahertz (MHz).

Here’s a breakdown of common channel width settings you'll encounter on your Mikrotik devices:

  • 20 MHz: This is like a narrow lane. It's generally more compatible with older devices and is less prone to interference. It's a solid choice in crowded WiFi environments where you want to minimize interference from neighboring networks. Using 20MHz is a good solution for the 2.4 GHz band, since it's very prone to interference. So, If your goal is to maximize the compatibility, 20 MHz is the way to go.
  • 40 MHz: This is like a wider lane. It allows for faster data transfer rates compared to 20 MHz. It's often used in the 5 GHz band, which tends to have less interference. But be aware that it can also be more susceptible to interference from other networks using the same channel.
  • 80 MHz and 160 MHz: These are the super-wide lanes, offering the highest potential speeds. They're available in the 5 GHz band and require devices that support these wider channels. However, they also need a clean WiFi environment with minimal interference to work effectively. If you live in an area with a lot of WiFi networks, these settings might not be the best choice because they can overlap and create issues.

The choice of channel width depends on several factors, including the WiFi environment, the devices you're using, and your desired performance. For instance, If you're using older devices that don't support wider channels, you'll be limited to 20 MHz. The 5 GHz band is generally less congested than the 2.4 GHz band, so you can often use wider channels (40, 80, or even 160 MHz) in the 5 GHz range to achieve faster speeds. A quick pro-tip is to check the airwaves around you using a WiFi analyzer tool. This tool will show you which channels are being used by other networks. You can use this information to choose a channel and width that will give you the best performance.

It is important to note that a wider channel width will provide higher throughput, but they require a higher signal-to-noise ratio. So, make sure the signal strength is good enough and there is not too much interference.

Understanding CE and EC in Mikrotik WiFi

Now, let's talk about CE and EC. These abbreviations relate to country settings and are crucial for complying with local regulations regarding WiFi frequency usage. These settings help your Mikrotik device to operate legally within your country.

  • CE (ConformitĂ© EuropĂ©enne): This marking indicates that the device complies with the European Union's safety, health, and environmental protection requirements. When configuring your Mikrotik device, you'll often see a setting related to the country code, which in turn sets the allowed channels and transmit power levels for your WiFi network. For example, if you're in Europe, you'll want to ensure that your device is configured to the correct CE country code. You'll need to select the right country from the list in your Mikrotik configuration. This selection will determine which WiFi channels are permitted for use and the maximum allowed transmission power. This is very important to make sure you're complying with the law.
  • EC (Economic Community) or ETSI (European Telecommunications Standards Institute): While not as widely used in the context of Mikrotik configuration as CE, understanding ETSI is still important. ETSI sets the standards for telecommunications in Europe, and your Mikrotik device must adhere to these standards to be compliant. These standards influence things like the allowed frequencies, transmission power, and channel bandwidths. Again, making sure your Mikrotik device adheres to these standards is essential for legal operation and preventing interference with other WiFi networks.

Basically, selecting the correct country code is how you ensure that your WiFi network is legal and won't interfere with other networks. This is especially important when using higher power settings. If you’re unsure about which settings to use, consult your local regulations or an expert.

Configuring Channel Width, CE, and EC on Mikrotik

Alright, let’s get down to the nitty-gritty of how to configure these settings on your Mikrotik device. The exact steps can vary slightly depending on the Mikrotik model and the RouterOS version, but the general process is the same.

  1. Access the Mikrotik Configuration: You'll typically access your Mikrotik device through Winbox, the web interface (WebFig), or the command-line interface (CLI) via SSH. Log in with your username and password.
  2. Navigate to Wireless Settings: In Winbox, go to the
