DD-WRT is Linux-based firmware for wireless routers and access points. Originally designed for the Linksys WRT54G series , it now runs on a wide variety of models. DD-WRT is one of a handful of third-party firmware projects designed to replace manufacturer's original firmware with custom firmware offering additional features or functionality.
Using this feature, compatible handsets are able to route regular cellular calls through a wireless LAN (Wi-Fi) network with broadband Internet, while seamlessly change connections between the two where necessary. [3] This feature makes use of the Generic Access Network (GAN) protocol, also known as Unlicensed Mobile Access (UMA). [4] [5]
Cisco introduced products ranging from modem access shelves (AS5200) to core GSR routers, making them a major player in the market. [23] In late March 2000, at the height of the dot-com bubble , Cisco became the most valuable company in the world, with a market capitalization of more than $500 billion.
WEP used a 64-bit or 128-bit encryption key that must be manually entered on wireless access points and devices and does not change. TKIP employs a per-packet key, meaning that it dynamically generates a new 128-bit key for each packet and thus prevents the types of attacks that compromised WEP.
Long-range Wi-Fi is used for low-cost, unregulated point-to-point computer network connections, as an alternative to other fixed wireless, cellular networks or satellite Internet access. Wi-Fi networks have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the environment. [1]
MIMO is often traced back to 1970s research papers concerning multi-channel digital transmission systems and interference (crosstalk) between wire pairs in a cable bundle: AR Kaye and DA George (1970), [5] Branderburg and Wyner (1974), [6] and W. van Etten (1975, 1976). [7]
