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.

What is the Scope of Work: 6 Examples and Guidelines for Writing SOW!

Definition:

The workload (SOW) is the most important stage of the discovery process, as it forms the basis for the future of the project. The terms of reference should include milestones, deadlines, results, and expectations. If a workload is not clear and detailed, the probability of failure or lack of communication with the client increases.

The SOW provides the necessary address for the project. In this way, the customer can meet all critical deadlines and ideas before receiving delivery. The SOW also allows the provider to clarify all questions and understand expectations before the next step. This movement aligns the vision and responsibility of both parties to ensure a successful final product.

Guidelines for Writing SOW

The Scope of Work (SOW) is the scope of an agreement that describes the work to be performed. The Terms of Reference must include all the milestones, reports, services, and final products that the executing Party is expected to provide. The terms of reference must also include a calendar for all deliverables.

The problem with most workspaces is the lack of specificity, that is when the two parties disagree with what should have been delivered, and one review of the SOW does not support one interpretation over the other. This problem is widespread in research agreements and often occurs where disputes occur. The best way to escape this problem is to avoid any ambiguity.

Scope of work must include the following components:

1. Glossary:

In the glossary, spell out any acronyms used in the SOW. Also, add definitions of weird or unusual terms. Think of the document from the perspective of a person who does not work in a particular industry or discipline.

2. Problem Statement:

Briefly describe the problem to be resolved with this exam (1 or 2 paragraphs are Ok). Describe the scientific and technological basis, i.e., the current state of the art or the development of the area to be promoted.

3. Objectives of the agreement

At the start of this section, complete the following sentence (please be brief):
The goal of this project is...Complete the sentence by briefly describing the objectives and explaining how to achieve them. Goals can be technical, economic, or social. Please be brief, maximum two to three sentences.

4. Purpose of the contract/services

Complete this section with measurable or identifiable project objectives at the end of this agreement. Here, the facilities provided must be listed. The services provided consist of a task and a final product.

Poor example:

Task: Assess classroom needs for public health awareness.

Deliverable: Write a program to meet your needs.

The difficulty with sow scope of work example above is that nothing is said. The task must be measurable, and quantifiable.

Good Example:

Task: Survey of 4 classes with 20 asthma-sensitized students. Each class answers a questionnaire containing 25 questions, assessing their general knowledge about public health-related asthma. An examiner should need about one hour to complete the survey with each class and another two hours per class to interpret the data.

Available: A 10-hour postgraduate program of up to 20 participants treats deficiencies in public health education in the prevention and treatment of asthma.

By reading the task and the deliverables, the administrative staff must be able to build the budget associated with the specifications. More importantly, there should be no question about the expectations of the exporting party when testing delivery items. A performance description can contain many results, but each must be broken down into tasks and end products to indicate what expected.

5. Administration

If there are meetings, calls, conferences, or other "informal" results, they should list in the Administration section of the service description. Any request that is not the end product of a particular task but is submitted by the performing party should describe in the Administration section of the mandate.

Poor example:

PI is asked to produce weekly progress reports during the soybean season, with more frequent reports during the high season.

The issue with the example above is that it does not specify what should be in the reports, which means "more often" and when the "hard time" is.

Example:

The PI is required to produce weekly reports, including analysis of wind patterns, fungal spore distribution, and potential risk areas. During the high season, from May 15 to July 15, CP may be asked to submit reports twice a week.

6. Timeline

This section contains all the data of the project. It specifies the dates of the tasks and the services to be provided. It also covers data for the central part of SOW.

There should be no ambiguity in the expectations of the exporting party between the glossary, the problem definition, the objectives of the agreement, the objectives/achievements, and the administrative components of the SOW. Together, these elements must provide a complete picture of what is expected when and in what form, taking into account specific requirements.

What is an Enterprise Support Engineer: 5 Common mistakes in working with Enterprise Support

Enterprise Support Engineer: Summary

As an Enterprise Support Engineer (ESE), you work directly with our most significant and most strategic business customers to identify, identify, and resolve your technical issues.
You become a trusted advisor and client advocate for accounts in your assigned portfolio: you get to know the customer's environment. Provide expert technical support and understand and defend your needs. It manages "business-critical" support escalations and acts as an active member of the account team.

In this role, you are accountable for working with important multi-level customer contacts, from technical and administrative contacts to executives. It helps identify IT goals, uncover customer weaknesses, make recommendations, and identify current and future IT needs. You will perform a significant role in helping our customers avoid unplanned disruptions by providing proactive guidance and recommendations for best operational practices, both tactical and strategic.

In this role, it is a crucial element to ensure the highest level of customer involvement. Through regular contact with your assigned customers, you will build deep relationships and use these relationships to conduct conversations that will ultimately help to gather detailed profiles of our clients. By capturing data and a deep-seated interest in questions, you can use your trusted advisor position to examine and understand key initiatives within your customer base and identify the areas in which BlueCat products can help achieve those goals.

5 Common mistakes in working with Enterprise Support

When your company enrolls in commercial support, it makes sense to leverage financial investment. However, I have seen several ways in which companies collaborate with commercial backing, resulting in poor results.

1. Do not think that Enterprise Support replaces employee training.

You may be asking relatively basic questions for AWS support. However, if you are primarily concerned with the commercial backing to answer basic questions about the use of this service, you can better spend your money on hiring in-house staff who are already familiar with AWS concepts. Despite all efforts, AWS cannot handle its applications as internal staff can and should.

2. DO NOT treat business support personnel as if you were the enemy.

Because they are not, I have seen people who have drawn definite lines between "us" and "them." These begin at the level of communication errors and continue in the area of ​​empathy errors.
Yes, I understand that you want to keep company information secret. You don't want to explain that the technical problem you are trying to solve is classifying Twitter for dogs' pets by breed and size. But you must find an acceptable way to share what you are trying to do, or professionals have a limited ability to help you. If you refuse to tell your account team what you are working on, you will not be bothered if it turns out that AWS is launching a service that will solve your specific problem.
AWS offers multiple services that can help solve everyday problems. It always amazes me how many times I see a structural problem in a client's environment that reflects what happens in another client's situation. If you are trying to move data from one place to another or omit a frustrating restriction on the AWS offer (or your perception of that restriction), talk to your account team first.

3. DO NOT be rude to the business support team.

If your first answer to any AWS service incident is to blame your answering machine, you're not just wasting your money, and you're also an idiot. TAMs are customer-oriented support staff. They cannot cause business interruptions (well, not without much creativity!), To break down business operations or to demand specific answers from customers of engineers who do everything in their power to respond to the disruption. By shouting at them, you become the commercial version of someone calling Dell to tell the poor phone support representative that your laptop is not working correctly.
You have the right to be upset when a service you pay for fails. However, it is not a productive use of one's time to eliminate this frustration in people who are often as dark as you.

4. YES, treat Business Support as more than a paid ticket tracking service.

Typically, engineers operate business support as if the sole responsibility of the support team was to track their AWS tickets. While tickets are essential (unfortunately, they are one of the few ways large companies internally communicate between multiple units), this is the smallest part of what enterprise support engineer companies offer. If you see support only in terms of troubleshooting, it makes more sense and more economically to hire a few people with the necessary skills to perform this function.

5. Understand that you need to restore the relationship regularly.

Business support has many benefits, but only if you and your team know they exist. To this end, it is crucial to understand how the relationship with the AWS era changes. You hire new staff; they shift the crew to an end, and suddenly you have a team of developers that have never officially submitted to commercial support. Update and renew this relationship regularly, especially if the organization has staff on both sides.
