Wearable devices can contain impressive sensors, but where those sensors sit on the body can be just as important as the hardware itself. A heart-rate sensor on the wrist, a motion sensor near the waist,…

A modern smartwatch can recognise a run, count repetitions, detect a hard fall, map an outdoor route, analyse walking patterns, and sometimes identify surprisingly subtle changes in movement. None of this comes from a single…

Premium smartwatches can now record an impressive collection of data. Heart rate, blood oxygen, ECG traces, skin temperature, sleep stages, running distance, elevation, stress estimates, and calorie expenditure can all appear on your wrist within…

Turn over a modern smartwatch and you will probably see a cluster of tiny LEDs flashing against your skin. Those lights may look simple, but they are part of a surprisingly sophisticated sensing system capable…

Wearable electronics used to be relatively simple. Early fitness trackers counted steps, estimated distance, and perhaps displayed basic heart-rate information. Today’s smartwatches and rings can combine optical sensors, electrical heart monitoring, temperature sensing, motion tracking,…

Mesh Wi-Fi systems are usually sold around one simple promise: place several nodes around your home and enjoy fast, seamless wireless coverage everywhere. In practice, adding more nodes does not guarantee better performance. The connection…

Mesh networking sounds simple: place several nodes around a building, connect them, and enjoy seamless Wi-Fi everywhere. In reality, large connected environments can become complicated very quickly. A large house, office, villa, multi-floor property, studio,…

A modern smart home can easily contain dozens of wireless devices before anyone even thinks about laptops and phones. Smart TVs, cameras, doorbells, speakers, lights, sensors, appliances, thermostats, tablets, gaming systems, and voice assistants may…

Routers are easy to judge by the number printed on the box. Wi-Fi 6, Wi-Fi 7, 10Gbps, eight antennas, and huge theoretical wireless speeds all sound impressive. Unfortunately, none of those specifications guarantee a fast…

A fast internet plan does not automatically create a fast home network. You can pay for multi-gigabit broadband and still experience unstable video calls, slow NAS transfers, gaming latency, or weak Wi-Fi in certain rooms.…
