Network Performance

Wireless Networks: Wi‑Fi, 5G, and Beyond Wireless networks connect homes, offices, and cities without wires. Wi‑Fi keeps devices linked indoors, while 5G extends mobile access to higher speeds and lower delays outside. Looking ahead, Wi‑Fi 7 and new cellular ideas aim to make both indoor and outdoor links faster and more reliable for everyday tasks. Small changes, like choosing the right channel or updating firmware, can make a big difference for stability and speed. ...

Mobile Networks and Edge-to-Device Connectivity Mobile networks are evolving beyond a simple link to the internet. Edge-to-device connectivity places computing resources close to phones, sensors, and wearables. This proximity lets data be processed near where it is created, cutting travel time and saving energy. The result is faster apps, smoother experiences, and new ways to use data in real time. Key ideas include low latency, higher efficiency, and better privacy. The edge sits at the boundary between the core network and the device, hosting small data centers and functions. With 5G and future generations, network operators offer edge services, such as mobile edge computing (MEC) and network slicing, to support diverse workloads. ...

Networking Essentials: Protocols, Topologies, and Latency Networks connect devices across rooms, cities, and oceans. To run smoothly, you need three basics: protocols, topologies, and latency. This article explains each idea in plain language, with simple examples you can use at home or in a small office. Protocols that drive networks Protocols are the rules that let devices talk to each other. The core Internet protocol suite is TCP/IP. It handles addressing, delivery, and error checking by splitting data into packets and sending them along paths that routers choose. These rules keep conversations reliable, even when networks change. ...

Mobile networks and 5G implications for apps Mobile networks are changing. 5G brings more capacity, lower latency, and new edge services. For app teams, this means faster responses and richer features, but it also asks for different design, testing, and deployment choices. A thoughtful approach helps apps stay smooth as networks vary around the world. What 5G changes for apps 5G can reduce delays between the device and servers and open new ways to run code near users. Edge computing lets some tasks happen closer to the user, cutting round trips. Network slicing can reserve resources for high-priority apps, which helps with reliability during busy times. As a result, real‑time features like live gaming, video calls, and augmented reality can feel more responsive. On the flip side, developers may see more variability in network conditions, so apps must be resilient. ...
