4G, the fourth generation of mobile telecommunications technology, is all about keeping things lightning-fast and always connected. This category houses a motley crue of trends - from the next-gen 5G, which aims to take connectivity to the next level, to the relatively unknown Link Micro LTE, which promises to be a game-changer for rural internet. Then there's Spypoint, a company that has taken security cameras to the next level with 4G-enabled solar-powered cameras. And let's not forget about the smartphones - the Vivo V21 and Samsung Galaxy S20 FE 4G, both promising to pack a punch. In short, 4G is about being fast, staying connected, and innovating to make things even better.
