A wireless network interface controller (WNIC) is a network interface controller which connects to a wireless network, such as Wi-Fi, Bluetooth, or LTE (4G) or 5G rather than a wired network, such as an Ethernet network. A WNIC, just like other NICs, works on the layers 1 and 2 of the OSI model and uses an antenna to communicate via radio waves.
Speeds on 2.5G networks are usually in the 30–50 kbit/s range. The first personal computer with a built-in mobile broadband modem was the ITC 286 CAT, a laptop by Intelligence Technology Corporation. Released in 1988, it featured a Hayes-compatible AMPS modem capable of transmitting data at 1.2 kbit/s. [3] [4]
The E220 connects to the computer with a standard Mini USB cable. The device comes with two cables, one short and one long. The long one has two USB A interfaces, one used for data and power and the other optionally only for assistance power in case the computer is not able to provide the full 500 mA (milliamperes) required for the device to work from one USB interface only.

Most Vodems and Vodem sticks are of reaching 7.2 Mbit/s. The original Huawei E220 supports up to 3.6 Mbit/s, and can connect up to 7.2 Mbit/s with a firmware upgrade. The Vodafone K5150 Vodem is a CAT4 4G device, capable of download speeds of up to 150 Mbit/s on a 4G LTE network [3] and 42.2 Mbit/s with a dual-carrier network.
Sometimes referred to as a "WUSB hub", a DWA allows existing USB 2.0 devices to be used wirelessly with a WUSB host. WUSB host capability can be added to existing PCs through the use of a Host Wire Adapter (HWA). The HWA is a USB 2.0 device that attaches externally to a desktop or laptop's USB port or internally to a laptop's MiniCard interface.
HOUSTON (AP) — When DeMeco Ryans became coach of the Houston Texans before last season, the two-time Pro Bowl linebacker brought his swarm defense with him.
Many Zigbee/IEEE 802.15.4-based wireless data networks operate in the 2.4–2.4835 GHz band, and so are subject to interference from other devices operating in that same band. The definition is for 16 channels numbered 11–26 to occupy the space, each 2 MHz wide and spaced by 5 MHz. The F 0 of channel 11 is set at 2.405 GHz. The DSSS scheme is ...
