Wireless USB (Universal Serial Bus) is a short-range, high-bandwidth wireless radio communication protocol created by the Wireless USB Promoter Group, which is intended to increase the availability of general USB-based technologies.
If the data is corrupted while transmitted or received, the CRC check fails. When this happens, the receiver does not generate an ACK, which makes the sender resend the packet. [13] When a device is reset with a SETUP packet, it expects an 8-byte DATA0 packet next. USB 2.0 added DATA2 and MDATA packet types as well. They are used only by high ...
Some of these technologies include standards such as ANT UWB, Bluetooth, Zigbee, and Wireless USB. Wireless Sensor Networks (WSN / WSAN) are, generically, networks of low-power, low-cost devices that interconnect wirelessly to collect, exchange, and sometimes act-on data collected from their physical environments - "sensor networks".

The Type Allocation Code (TAC) is the initial eight-digit portion of the 15-digit IMEI and 16-digit IMEISV codes used to uniquely identify wireless devices. The Type Allocation Code identifies a particular model (and often revision) of wireless telephone for use on a GSM , UMTS , LTE , 5G NR , iDEN , Iridium or other IMEI-employing wireless ...
For OS X releases beginning with 10.11, and for macOS releases, varieties of apples were used as internal code names. [ 94 ] Mac OS X : Cyan, Siam (in reference to joining Mac OS and Rhapsody) [ 91 ]
The term, Subsidy Password, is used by Motorola and other handset manufacturers to refer to the 8-digit code (or 16-digit code for phones such as the Motorola K1) unlock code necessary to remove the operator lock (also known as subsidy lock) from cell phones.
These codes are broadcast as 15 bit values but transmitted as 16 bits by core network protocols. They can be listed within a wireless device to show preference for one network over another. The additional bit in core network protocols allows the range of codes above 32,767 to be used for internal purposes, such as segregating billing records ...
