The USB On-The-Go logo. Non-compliant USB On-The-Go adapter for a defective smartphone or tablet computer. Some products were made with defective ports that do not accept Micro-A plugs. Instead, they were designed to accept Micro-AB plugs, which are similar to Micro-A plugs but have a different shell. This means that Micro-A plugs cannot be ...
Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
The first-generation iPad Pro (12.9-inch models only), and the second-generation iPad Pro, are the only devices with the Lightning connector supporting USB 3.0 host. [9] The only accessory released with USB 3.0 support is the Lightning to USB 3 Camera Adapter. [10] Since iPhone 8 and iPhone X, the Lightning connector is somewhat USB-PD ...
Residential wireless phones, USB 3.0 Hubs, baby monitors, wireless cameras, remote car starters, and Bluetooth products are all capable of transmitting in the 2.4 GHz band. Due to the intended nature of the 2.4 GHz band, there are many users of this band, with potentially dozens of devices per household.
IEEE 802.11ac-2013. *Wi‑Fi 0, 1, 2, and 3 are named by retroactive inference. IEEE 802.11ac-2013 or 802.11ac is a wireless networking standard in the IEEE 802.11 set of protocols (which is part of the Wi-Fi networking family), providing high-throughput wireless local area networks (WLANs) on the 5 GHz band.
IEEE 802.11ax is the successor to 802.11ac, marketed as Wi-Fi 6 (2.4 GHz and 5 GHz) [74] and Wi-Fi 6E (6 GHz) [75] by the Wi-Fi Alliance. It is also known as High Efficiency Wi-Fi , for the overall improvements to Wi-Fi 6 clients in dense environments . [ 76 ]
A USB cable, by definition, has a plug on each end—one A (or C) and one B (or C)—and the corresponding receptacle is usually on a computer or electronic device. The mini and micro formats may connect to an AB receptacle, which accepts either an A or a B plug, that plug determining the behavior of the receptacle.
Despite USB 3.0 being 10 times faster than USB 2.0, USB 3.0 transfer cables are only 2 to 3 times faster given their design. [clarification needed] The USB 3.0 specification introduced an A-to-A cross-over cable without power for connecting two PCs. These are not meant for data transfer but are aimed at diagnostic uses.
