Wireless networks communicate using electromagnetic waves transmitted through antennas without physical connections like wires. They have advantages over wired networks such as quick installation, mobility, and lower maintenance costs. There are different types of wireless networks including WPAN for personal networks covering short distances, WLAN for local networks, WMAN for metropolitan networks, and WWAN for wide area networks. Key wireless technologies discussed include Bluetooth, WiMax, and protocols for mobile phones.

Wireless Technologies Presented by Sean Shields And Gabriel Taveras Definition Term “Wireless” refers to all the communications sent and received without wires. So Wireless Technology Means a technology that use radio waves to transmit or receive data. Wi-Fi Bluetooth Cellular Wimax TYPES OF TECHNOLOGIES INTRODUCTION: Wireless Fidelity termed as Wi-Fi uses the IEEE 802.11 specification to create a wireless local-area network. A Wi-Fi network basically consists of a wired connection to the Internet that leads to a wireless router for transmutation and receiving data from individual devices, connecting them not only to the outside world but also to each other. HOW WIFI WORKS? 1. All devices use a wireless adapter to convert request into a radio signal and broadcasts it into the air. 2. The Wi-Fi device, or wireless router, picks up the signal and translates it back into its original form. 3. The router passes the request to the Internet using a hardwired connection. 4. The Internet returns the requested information to the router across the same connection. 5. The router converts the information into a radio signal and broadcasts it into the air. 6. The computer or cell phone's wireless adapter picks up the information and displays it on your screen WIFI TOPOLOGIES Wifi have following topologies AP-based topology (Infrastructure Mode) Peer-to-peer topology (Ad-hoc Mode) Point-to-multipoint bridge topology Wi Fi Network Wireless Standards 802.11 In 1997, the Institute of Electrical and Electronics Engineers (IEEE) created the first WLAN standard. They called it 802.11 after the name of the group formed to oversee its development. Unfortunately, 802.11 only supported a maximum network bandwidth of 2 Mbps - too slow for most applications. For this reason, ordinary 802.11 wireless products are no longer manufactured. Wireless Standards 802.11b IEEE expanded on the original 802.11 standard in July 1999, creating the 802.11b specification. 802.11b supports bandwidth up to 11 Mbps, comparable to traditional Ethernet. Wireless Standards 802.11a Supports bandwidth up to 54 Mbps and signals in a regulated frequency spectrum around 5 GHz. This higher frequency compared to 802.11b shortens the range of 802.11a networks. The higher frequency also means 802.11a signals have more difficulty penetrating walls and other obstructions. Wireless Standards 802.11g Attempts to combine the best of both 802.11a and 802.11b. 802.11g supports bandwidth up to 54 Mbps, and it uses the 2.4 Ghz frequency for greater range. 802.11g is backwards compatible with 802.11b, meaning that 802.11g access points will work with 802.11b wireless network adapters and vice versa. Wireless Standards 802.11n The newest IEEE standard in the Wi-Fi category is 802.11n. 802.11n connections support data rates of over 100 Mbps. 802.11n also offers somewhat better range over earlier Wi-Fi standards due to its increased signal.

Dubai, known for its towering skyscrapers, luxurious lifestyle, and relentless pursuit of innovation, often finds itself in the global spotlight. However, amidst the glitz and glamour, the emirate faces its own set of challenges, including the occasional threat of flooding. In recent years, Dubai has experienced sporadic but significant floods, disrupting normalcy and posing unique challenges to its infrastructure. Among the critical nodes in this bustling metropolis is the Dubai International Airport, a vital hub connecting the world. This article delves into the intersection of Dubai flood events and the resilience demonstrated by the Dubai International Airport in the face of such challenges.

The microservices honeymoon is over. When starting a new project or revamping a legacy monolith, teams started looking for alternatives to microservices. The Modular Monolith, or 'Modulith', is an architecture that reaps the benefits of (vertical) functional decoupling without the high costs associated with separate deployments. This talk will delve into the advantages and challenges of this progressive architecture, beginning with exploring the concept of a 'module', its internal structure, public API, and inter-module communication patterns. Supported by spring-modulith, the talk provides practical guidance on addressing the main challenges of a Modultith Architecture: finding and guarding module boundaries, data decoupling, and integration module-testing. You should not miss this talk if you are a software architect or tech lead seeking practical, scalable solutions. About the author With two decades of experience, Victor is a Java Champion working as a trainer for top companies in Europe. Five thousands developers in 120 companies attended his workshops, so he gets to debate every week the challenges that various projects struggle with. In return, Victor summarizes key points from these workshops in conference talks and online meetups for the European Software Crafters, the world’s largest developer community around architecture, refactoring, and testing.

Tracing the root cause of a performance issue requires a lot of patience, experience, and focus. It’s so hard that we sometimes attempt to guess by trying out tentative fixes, but that usually results in frustration, messy code, and a considerable waste of time and money. This talk explains how to correctly zoom in on a performance bottleneck using three levels of profiling: distributed tracing, metrics, and method profiling. After we learn to read the JVM profiler output as a flame graph, we explore a series of bottlenecks typical for backend systems, like connection/thread pool starvation, invisible aspects, blocking code, hot CPU methods, lock contention, and Virtual Thread pinning, and we learn to trace them even if they occur in library code you are not familiar with. Attend this talk and prepare for the performance issues that will eventually hit any successful system.
