The interface speed can also differ. For example, in inexpensive router models, Internet speed through the WAN will be limited to 100 mbps, while the local network (over the LAN) can be gigabit, that is up to 1 gbps.

Cable networks cannot cover all spaces where high speed internet is needed or desired. They are also affected by topology, the relative complexity of installation, and the limited end users of the network. Under such circumstances, WLAN and Wi-Fi is the best solution.
WLAN, what is it? What is the difference between a WLAN? It is a point of access to the Internet, a modern technology for transmitting information via radio signals, without the presence of cable connections. WLAN stands for Wireless Local Area Network. The presence of special modules in smartphones, tablets, laptops or stationary PCs allows users to receive a stable signal within the coverage limits, both when stationary and on the move.
Benefits of the technology
The main advantages of such a technological solution are as follows:
Technology is currently developing rapidly, which makes having such an access point as WLAN in a modern phone a necessity. The cell phone now is not just a tool for calling and messaging, but a full-featured device for work and entertainment. Whether iOS, Microsoft's mobile version, Android is installed in the gadget, WLAN will definitely be available there.
The concept of wireless networking
WLAN stands for Wireless Local Area Network, which in Russian means "wireless local area network". During its operation, it uses radio frequencies rather than cable networks (as in the case of a conventional wired connection) to establish communication and transmit data. This makes it independent of the specific space and available to a large number of users. The most popular technology currently in use for transmitting information over radio waves is Wi-Fi.
Wi-Fi is an abbreviation derived from the term Wireless Fidelity, which means "wireless reliability". By using this technology, users have access to the network throughout its coverage area. Most laptops are labeled Wi-Fi, meaning that they are compatible with WLAN networks.
What is wireless coverage area and what does it depend on? It's nothing more than the Wi-Fi coverage area, within which users can move around without disrupting the connection. As a rule, the distance over which signals can be transmitted is about 100 meters. This depends on many factors, in particular on the number and type of obstacles. In any case, WLAN is a more reliable way of connecting than cable networks. The number of users is practically unlimited, and the range can be expanded by installing overlapping (additional) access points and increasing the number of users in one area.
WLAN on your phone
It is possible to access the virtual network not only from a computer/laptop, but also from a cell phone. What is WLAN in the phone and how do I use it? In essence, it is the usual wireless Internet, but not on a portable PC, but on your cell phone. This feature is now built into all modern models and can be very convenient. For example, you can use Wi-Fi while sitting in a cafe or waiting for your flight at the airport – in general, in any public place where there is an appropriate coverage area. The use of the service is usually free and does not depend on the presence/absence of a SIM card. The only disadvantage is that the battery drains quickly enough. You can connect Wi-Fi (WLAN) in the phone's "Wireless Networks" settings, if you are within the range of the access point.
What is a WLAN port?
A wireless local access network (WLAN) is a limited local wireless network. A WLAN port is a device that allows computers to connect to the WLAN. Essentially, a WLAN port is a type of router. The difference between these devices and a standard router is usually the ports. Most routers for standard network connections have at least two wired ports, while a WLAN port usually has none. The only way to connect to one of these devices is through a wireless connection. To understand what a WLAN port is and what it is not, you need to know a few networking terms. A Local Access Network (LAN) is a network that exists in your home or office and to which all your computing devices are connected. A wide area network (WAN) is a network outside the local area network, in general often just the Internet. A router allows the user's computing devices to connect to the network; it is basically the center of the system as well. Finally, a wireless router for physically connecting devices contains both ports, such as computers and game consoles, and wireless systems, such as laptops and some cell phones.
In most cases, a wireless or wired router will have at least two wired ports, but can have many more. As computer devices increasingly switch to wireless connections, these ports are being used less and less. Some router companies have begun to create routers that have no wired ports at all; they only allow you to connect wireless systems. These devices have several names, one of which is the WLAN port.
In general, a WLAN port is exactly the same as a standard router, except for the wired connections. It will perform all routing functions and provide a basic firewall, just as the user expects from a standard router. The biggest difference is the initial connection. Many standard routers require a wired connection to do the initial setup processes; since this is not possible in this case, it is not required.
Connection between WLAN and Wi-Fi
Wi-Fi is a cell with a diameter of up to 100 meters, within which a wireless LAN ensures the connection of many different gadgets and computers.
The range of the Wi-Fi signal depends on the environment through which it travels. The maximum range is achieved in open spaces, such as within a room, cafe halls, etc.
When passing through walls and ceilings, the signal is weakened, as well as if its path meets Powerful sources of electromagnetic radiation – microwave ovens, etc.
Advantages of the technology
Among the main advantages of this technological solution are the following:
- Convenience. This advantage applies to both network owners and end users. In the first case, installation and configuration of WLAN is cheaper than laying cable. Also, in some cases, laying cable is simply impractical or impossible due to the terrain, location of buildings and communications. Users are able to use stable high data transfer speeds in a given coverage area.
- Network expansion. The technology can be easily expanded by installing additional access points.
- Mobility. Coverage virtually ignores obstacles, allowing you to use the network with equal success on the move, on different floors or levels, in different rooms.
- Ease of installation. Construction is much easier compared to laying cables.
- High speed and excellent coverage. The speed is comparable to a wired connection and reaches 100 Mbit / s.Protected signal reception is carried out within a radius of 150 m, and the availability of additional access points can be further expanded.
- Simultaneous work of several subscribers with the same signal level in each.
- Interconnection. Vlan is perfectly compatible with numerous devices from different manufacturers.
WLAN and smartphone
Technology is advancing rapidly, so a WLAN access point on a modern phone is a must. The cell phone is no longer just a tool for calling and messaging, but a full-fledged device for work and entertainment. IOS, Microsoft mobile version, whether Android is installed on the device, WLAN will definitely be available there.
How to set up the switch
1. Download the Commands app from the App Store.
2. Add a useful command at the link.
3. Edit the command and save it.
As you can see from the item names, the script can perform four actions:
When editing a command, you can rename each of the items or remove unnecessary items.
4. Make sure that the voice assistant is enabled on the iPhone.
Without Siri, our right button will not work. You won't have to call it by voice, but there is a system limitation.
How it works now
The added switch will immediately appear in the application widget Commands. It can be launched from a locked screen or a page with widgets.
After clicking on it you will see four buttons with available options, one click and the desired module is enabled or disabled.
Don't forget that the button can be activated via 3D-Touch menu of the Commands app, through the shortcut desktop shortcut or via Siri .. Read more about how to activate scripts here.
Tip: If you want to be controlled by Siri, copy the command as many times as you want and leave only one button in each script. Now give each script a voice command individually and control the switches with your voice.
