A WWAN may also be a low-power, low-bit-rate wireless WAN, , intended to carry small packets of information between things, often in the form of battery operated sensors. Since radio communications systems do not provide a physically secure connection path, WWANs typically incorporate encryption and authentication methods to make them more secure.
Wireless network cards for computers require control software to make them function (firmware, device drivers). This is a list of the status of some open-source drivers for 802.11 wireless network cards. Location of the network device drivers in a simplified structure of the Linux kernel.
HP EliteBook is a line of business-oriented laptop computers made by Hewlett-Packard (), [1] marketed as a high-end line positioned above the ProBook series. [2] The line was introduced in August 2008 [3] [4] as a replacement of the HP Compaq line of business laptops, and initially included mobile workstations until September 2013, when they were rebranded as HP ZBook.

This notebook computer is connected to a wireless access point using a PC Card wireless card. An example of a Wi-Fi network. A wireless LAN (WLAN) is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building.
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.
A wireless configuration utility, [1] wireless configuration tool, [1] wireless LAN client, [citation needed] or wireless connection management utility [citation needed] is a class of network management software that manages the activities and features of a wireless network connection.
A common example is the Wi-Fi Protected Setup system included in most access points manufactured since 2007 when the standard was introduced. [7] Wi-Fi Protected Setup allows access points to be set up simply by entering a PIN or other identification into a connection screen, or in some cases, simply by pressing a button.
