What is a WLAN connection?

Technology

Wireless local area network (WLAN) is a wireless network system for two or more devices. WLANs use high frequency radio waves and include internet access. WLAN allows users to navigate the coverage area, when a small home or office, maintains a network connection.

WLAN should not be included in the Wi-Fi Alliance logo. First, where the terms “Wi-Fi” and “WLAN” can be used in playback, there are different types of games where “Wi-Fi connection” refers to the wireless connection of the device, WLAN is a network itself, which is different.

Also, “Wi-Fi” is not a manual operation, but is defined as the platform of the IEEE 802.11 standard and is sometimes used in conjunction with the standard. However, not all Wi-Fi devices are supported by the Wi-Fi Alliance, despite the fact that more than seven million people use Wi-Fi through 750,000 internet connections. The heaters themselves are also WLAN, of a special type.

WLAN and access points

Each component that connects to a WLAN is considered a station and falls into one of two categories: access points (APs) and clients.

Access points or APs transmit and receive radio frequency signals with devices capable of transmitting signals; they usually act as a router.

Conversely, clients can include a variety of devices such as desktops, workstations, laptops, IPs, and other mobile phones and smartphones.

All stations that can communicate with each other are called basic service sets (BSS), which are of two types: standalone and infrastructure. Independent BSS (IBSS) exist when two clients communicate without using AP, but cannot connect to any other BSS. Such WLANs are called peer-to-peer or ad-hoc ad hoc WLANs. The second BSS is called the infrastructural BSS. It can only communicate with other stations in other BSS and must use AP.

Emerging WLANs and WLAN ubiquity

In the early 1990s, WLANs were very expensive and were only used when wired connections were strategically impossible.

By the late 1990s, most WLAN systems and building codes had IEEE 802.11 standards in various formats (“a” through “n” versions). WLAN prices also began to plummet.

As technology advances, it will be easier to set up and maintain WLANs.

This led to the emergence of the WLAN ISP, where small residential networks are usually connected to it by Internet service providers, not on sites repaired by end users.

In the WLAN ISP type model, the ISP modem is the access point. It is also a router. All customers need to do is install the router, use the security password provided, and connect the home device to the home WLAN.

Could refer to this as “local air conditioning as a service” (WLANaaS) or refer to plug-in or local air conditioning type. Either way, it is easier for the family in the end.

While ISPs don’t usually advertise their products as home LANs, that’s the case. Some types of ISPs talk about using modems as a “gateway” to the Internet, which means that your WLAN is on the other side of that portal.

Home WLAN users often connect devices such as phones, TVs, computers, and printers to advanced WLAN systems.

There has also been an innovation with WLAN peers that operate without a specific access point. In other words, all devices operate independently to connect to the

network. This calls into question the traditional idea of ​​WLAN access points and customers, as mentioned above. At the same time, in the client / server architecture, where similar services are used to design Internet services, peer-to-peer systems also question this traditional construction.

When IoT paves the way for advanced connectivity, WLAN provides that “subnet” and convenience for local Wi-Fi operation.

WLAN type

Two main types of WLAN are explained below:-

Wireless network devices

In this type of wireless network, access points (APS) are used to establish communication between devices. The access point connects to a router, hub, or switch via an Ethernet cable, and the access point uses Wi-Fi signals to share connectivity with wireless devices.

Wireless access centers establish connections with terminals (smartphone, tablet, laptop, work center, etc.). In such connections, APS (access points) act as the primary station (BS) in cellular systems. The main problem with this network is that it is not portable.

As shown in the figure above, the access points are connected to a switch switch by wires. And wireless communication is made between access points and customers (laptop, smartphone, tablet or workplace)

Wireless ad hoc network:

In this type of network, no access points or wired connection are used. Also, no fixed network parts are used. The example of this type of connection is the Wi-Fi access point. In the Adhoc network, one device acts as a master and other devices act as a slave or client. If you have a device such as a smartphone connected via Wi-Fi, you can access the internet within a certain range. If you move beyond the range, the Wi-Fi connection will be disconnected. For example, if you use Wi-Fi at home and move away from home, your Wi-Fi connectivity is lost at some distance.
