Ultra-wideband (UWB, ultra wideband, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. The following is a list of devices that support the technology from various UWB silicon providers.
The service is sold exclusively to Comcast internet subscribers, and includes access to Xfinity WiFi. [116] [115] Analysts perceived Xfinity Mobile as being a response to AT&T's acquisition of DirecTV, which added the national satellite provider alongside its existing wireline and wireless services, and an increased push towards mobile ...

Within a single band group, the maximum number of non-overlapping channels is actually three. Any time two devices are transmitting at the same frequency and within radio range (<10m), regardless of their logical channel they will either look like noise to each other or must logically share the timeslots in the channel.

The iPhone 12 features a 6.1-inch (155 mm) display [33] with Super Retina XDR OLED technology at a resolution of 2532 × 1170 pixels and a pixel density of about 460 ppi. [34] The iPhone 12 Mini features a 5.4-inch (137 mm) display with the same technology at a resolution of 2340 × 1080 pixels, and a pixel density of about 476 ppi.
These include design flaws in the Wi-Fi standard, affecting most devices, and programming errors in Wi-Fi products, making almost all Wi-Fi products vulnerable. The vulnerabilities impact all Wi-Fi security protocols, including WPA3 and WEP. Exploiting these flaws is complex but programming errors in Wi-Fi products are easier to exploit.
A wireless network interface controller may be implemented as an expansion card and connected using PCI bus or PCIe bus, or connected via USB, PC Card, ExpressCard, Mini PCIe or M.2. The low cost and ubiquity of the Wi-Fi standard means that many newer mobile computers have a wireless network interface built into the motherboard.
