What is a WLAN? Definition, Types, Pros and Cons

What is a wireless LAN? We live in a period when technological progress is at its highest. In particular, there is a crucial element of network transmission in the technological world. There are two main kinds of network transmission, which include wired communication and wireless network transmission.

In this context, it can be comprehended that wireless LAN designates local transmission through the Internet, the communication existence through radio waves. In particular, the distribution takes place via radio waves which have an access point on the Internet.

Remarkably, there is a critical element of network communication in the world of technology. They are wired and connected in a wireless network. To simplify the previous question on "What is WiFi?" (Wireless local area networks) WLAN doesn't want a wired Ethernet link.

Types of WLANs

What is the access method used by Wireless LAN? According to IEEE 802.11, WLANs work in two basic modes: infrastructure and ad hoc mode.

Infrastructure mode - Mobile devices or clients establish a connection to an access point (AP), which in turn connects to the LAN or the Internet via a bridge. The client transfers frames to other clients via the AP.

Ad hoc mode - customers transfer frames directly from peer to peer.

Advantages of WLAN

Flexibility: in radio coverage, nodes can communicate without other restrictions. Radio waves can penetrate walls, transmitters, and receivers can be located anywhere (not visible, for example, on devices, fences, etc.).

Planning: only ad hoc wireless networks allow communication without prior planning. Each cable network requires wiring plans.

Design: wireless networks allow the design of small independent devices that can keep in a pocket, for example. Cables restrict not only users but also designers of small laptops, PDAs, etc.

Robustness: wireless networks can cope with disasters such as earthquakes, floods, etc.

Cost: The cost of installing and continuing a WLAN is, on average, lower than the price of establishing and maintaining a traditional wired LAN for two reasons. First, adding additional users to a network does not add any cost once the first user has obtained wireless access to the wireless network through an access point. Second, the wireless LAN eliminates direct wiring and labor costs for installation and repair.

Ease of use: the wireless LAN is easy to use, and users need very little new information to take advantage of WLANs.
Disadvantages of WLANs

Quality of service: The quality of WLAN is commonly lower than that of wired networks. The leading causes for this are the lower bandwidth due to radio transmission limitations, higher error rates due to interloping, and higher interruption fluctuations due to error correction and detection tools extended.

Proprietary solutions: Due to the slow normalization process, many corporations have developed proprietary solutions that offer standardization and many innovative functions. Most components today comply with basic IEEE 802.11a or 802.11b standards.

Restrictions: Multiple governments and non-governmental institutions around the world regulate operations and limit frequencies to minimize interference.

Worldwide use: WLAN products sold in all countries, so national and international frequency regulations must observe.

Low energy consumption: Devices that communicate over a wireless local area network regularly consume energy as well as wireless devices that run on batteries. The LAN design must take this into account and implement unique energy-saving modes and energy management functions.

Operation without a license: LAN operators do not want to request a special permit to use the product. The device must operate in an unlicensed band such as the 2.4 GHz ISM band.

Robust transmission technology: If the WLAN uses radio transmission, many other electrical devices can interfere with it (e.g., vacuum cleaners, traction motors, hairdryers, etc.). Surroundings.

LAN and Wi-Fi

One of the most usual methods of creating a WLAN today is using Wi-Fi. It refers to a set of standards that relate to the collection of rules for electrical and electronic engineers that start with the number 802.11. Different Wi-Fi standards can be identified by their 802.11 standard amount, such as B. 802.11b or 802.11g, or by other more verbose names such as Wi-Fi 6 or Wireless G.

In-home and work Wi-Fi networks, devices called access points typically look for connections from nearby computers. Often routers can efficiently route traffic over the local network and to and from the Internet. Routers often support multiple versions of the Wi-Fi standards so that they can help multiple generations of devices. However, when setting up a network, you need to make sure that all of your tools are compatible with it.

Most modern laptops and cell phones support Wi-Fi, and you can check the box on your device or its documentation to determine which versions of the standard it works with. You can purchase an external adapter if you need to communicate with another type of Wi-Fi network.

Service Desk Technician: What it is and Tips to Run a Friendly Service Desk

A service center is a communication center that provides a single point of contact between a company and its customers, employees and business partners. The purpose of a service center is to ensure that users receive prompt and adequate assistance.
Service tables are designed to handle incidents and service requests. In this context, an incident is an event that causes a disruption in the availability or quality of service. A service request requests help with routine tasks, such as changing a user's password or setting up a new user on work systems. Other services provided may include change management, version control, and configuration tasks.
The service center is one of the three primary customers and user service options. The other two SPOC units are call centers and assistance centers. The difference between the help desk and support services is confusing. As defined by ITILv.2, Service Desk was just another term for Help Desk. However, ITILv.3 distinguishes the two because service desks offer a wider range of service features, solve more problems in fewer steps and allow the integration of business processes into the service management infrastructure.
The ITIL (Information Technology Infrastructure Library) defines the service center as an essential IT service management tool (ITSM). ITIL is a collection of world-renowned best practices for managing IT services.
What is an IT Service Desk?
The IT service desk should be an important compromise between users also an IT association. According to ITIL, the IT service desk is the only point of contact (SPOC) between the service provider (IT) and the users for daily activities. A typical service desk handles incidents (service interruptions) and service requests (routine service tasks), as well as managing user communications for things like interruptions and scheduled service changes. A service desk generally has enormous scope and is designed to provide the user with a unique location for all their IT needs. As a result, the service desk plays a fundamental role in facilitating the integration of business processes with the broader infrastructure for technological ecosystem and service management.

We do business with those we manage. In times of technology and digital connections, it is these personal relationships that drive growth and achieve strategic goals.
But when it comes to satisfying customer needs and maintaining business operations, we would not be far off without technology. The IT Service Tables keep everything that businesses do and connect in process. What makes it more critical than ever that the service tables are easy to use and meet the needs of customers.
In some companies, such as a technology company, customer service also acts as front-line customer service, making it all the more important as these contact points define the relationship with the customer.
Here are some ways to make sure your IT service delivers world-class, friendly service.
1. Take into account the requirements of the client
The needs of the customer (end-user) have priority. Start with them. Do not let technology guide you. Make sure the technology is tailored to the user's needs and feels neat. Make sure they can easily give their opinion and learn from any complaints.
Giving customers priority means offering services proactively. Work to provide customized services. It may mean that advanced self-service options are provided to resolve common issues. Also, make sure that the communication between the service desk analyst and the customer is smooth. These include newsletters, blogs, and resources that help users solve recurring problems themselves, especially when working with customers who want to quickly learn about new technologies.
2. Clear, scalable and human-centered processes
IT service center processes must be documented. It can scale without unique methods. You can not provide a first-class service. It is also more challenging to make improvements, make changes and train new members. All these processes must be adapted to the needs of the customers. Changes should make as new ideas emerge, new technologies incorporated, and self-service options proposed.
3. Provide technology improved to your needs
IT Service Management (ITSM) tools have evolved significantly in recent years. To get the work done and meet your performance goals, you need a wide range of features, from automated robots to self-service portals, to communication channels (including live chat) that meet modern needs. Client.
If you serve hundreds or thousands of customers, you need to make sure that these solutions are deployed on a large scale, which can include a service desk application so they can always access support tickets. Primarily if you work remotely or around the world.
4. Keep learning, keep improving
Delivering world-class, comprehensive service is essentially about leveraging customer feedback, data, and results against goals. IT Service Desk Engineer only grows when they invest in reporting systems, training and personal development.
Using customer feedback and data is the only way to improve, as these enhancements are integrated with new technologies, tools, and processes to ensure the best possible customer service. It's challenging to manage a user-friendly IT service center with limited human and technical resources. Companies in this position, with a small IT office and growing needs, often consider outsourcing to be the most cost-effective way to deliver world-class service consistently.
