Motorola Timeport, the first tri-band mobile phone (1999) A dual band 4G+ router. In telecommunications, a multi-band device (including (2) dual-band, (3) tri-band, (4) quad-band and (5) penta-band devices) is a communication device (especially a mobile phone) that supports multiple radio frequency bands. All devices which have more than one ...
Some devices with dual-band wireless network connectivity do not allow the user to select the 2.4 GHz or 5 GHz band (or even a particular radio or SSID) when using Wi-Fi Protected Setup, unless the wireless access point has separate WPS button for each band or radio; however, a number of later wireless routers with multiple frequency bands and ...
IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet. The standards are produced by the working group of the Institute of Electrical and Electronics Engineers (IEEE).

The modem connects to a single computer or router, through an Ethernet port, USB port, or is installed in a computer PCI slot. The more common DSL router is a standalone device that combines the function of a DSL modem and a router, and can connect multiple computers through multiple Ethernet ports or an integral wireless access point.
In those times, the fastest asynchronous voice-band modem could achieve at most speeds of 300 bit/s using frequency-shift keying (FSK) modulation, while synchronous modems could run at speeds up to 9600 bit/s using phase-shift keying (PSK). Synchronous transmission used only slightly over 80% of the bandwidth of the now more-familiar ...

[13] [n 1] A null SSID (the SSID element's length field is set to zero [11]) is called a wildcard SSID in IEEE 802.11 standards documents, [14] and as a no broadcast SSID or hidden SSID in the context of beacon announcements, [13] [15] and can be used, for example, in enterprise and mesh networks to steer a client to a particular (e.g. less ...
