Moderate WiFi users will find that dual-band routers offer smooth sailing, even for 4K streaming. As you can guess, this all makes for dramatically faster real-world performance. MU-MIMO) and the signal-boosting technique known as beamforming. They also support more modern tech, such as fast-transmitting data standards (like Next-Gen AC, a.k.a.

5 GHz frequencies offer much faster data transmission than their 2.4 GHz counterparts-each 5 GHz frequency features twenty-three non-overlapping channels, compared to just three non-overlapping 2.4 GHz channels. Now imagine adding new, totally open roads for data to travel down. On the 2.4 GHz frequency band, every device in the area competes for bandwidth-nearby routers, Bluetooth gadgets, kitchen appliances, and even baby monitors. Nowadays, dual-band routers pack-you guessed it-two bands (2.4 GHz and 5 GHz frequencies), while tri-band routers add a third band to the mix (another 5 GHz frequency). WiFi travels on frequencies called radio bands, but old school routers typically only offer one band for data to travel on. Like the average connected family, your home likely has upwards of eight devices using the network simultaneously, making a stable WiFi connection all the more important. A rule of thumb: the higher the Mbps you can achieve, the more stable your network will be for your whole household.

Internet service providers offer different speed tiers, and top-tier broadband services can net you WiFi speeds of up to 300 Mbps. Most 4K TVs fall into the “smart” TV category, which means they're ready to receive WiFi out of the box. To ensure you have plenty of bandwidth for 4K, you'll need broadband service such as cable or fiber Internet. To match this new standard, your home WiFi has to be up to par.įor a buffer-free experience, DSL-or phone-line-based Internet that averages speeds of about 5 megabits per second (Mbps)-isn't going to cut it. Every day, the pool of 4K films expands-Netflix and Amazon now shoot their original programming in Ultra HD, and even YouTube's bite-sized content is quickly upping its resolution ante.
