Data Communications: Wireless Networks

Wireless network refers to any type of computer network that is wireless, and is commonly associated with a telecommunications network whose interconnections between nodes are implemented without the use of wires. Hi-Tech Enterprises, Inc. can implement your wireless network such as a WPAN, WMAN, WLAN, and WWAN.

Hi-Tech Enterprises, Inc. is able to assist you with implementing a Wireless System in your business! Wireless Networks can include the folowing:

WPAN

Wireless Personal Area Network - a personal area network - a network for interconnecting devices centered around an individual person's workspace - in which the connections are wireless. Typically, a wireless personal area network uses some technology that permits communication within about 10 meters in other words, a very short range. One such technology is Bluetooth.

A WPAN could serve to interconnect all the ordinary computing and communicating devices that many people have on their desk or carry with them today - or it could serve a more specialized purpose such as allowing the surgeon and other team members to communicate during an operation.

A key concept in WPAN technology is known as "plugging in". In the ideal scenario, when any two WPAN-equipped devices come into close proximity (within several meters of each other) or within a few kilometers of a central server, they can communicate as if connected by a cable. Another important feature is the ability of each device to lock out other devices selectively, preventing needless interference or unauthorized access to information.

WMAN

Wireless Metropolitan Area Network - a network spanning a physical area larger than a LAN but smaller than a WAN, such as a city. A WMAN is typically owned an operated by a single entity such as a government body or large corporation.

The term is applied to the interconnection of networks in a city into a single larger network (which may then also offer efficient connection to a wide area network). It is also used to mean the interconnection of several local area networks by bridging them with backbone lines. The latter usage is also sometimes referred to as a campus network.

WLAN

Wireless Local Area Network - provide wireless network communication over short distances using radio or infrared signals instead of traditional network cabling.

A WLAN typically extends an existing wired local area network. WLANs are built by attaching a device called the access point (AP) to the edge of the wired network. Clients communicate with the AP using a wireless network adapter similar in function to a traditional Ethernet adapter.

Network security remains an important issue for WLANs. Random wireless clients must usually be prohibited from joining the WLAN. Technologies like WEP raise the level of security on wireless networks to rival that of traditional wired networks.

WWAN

Wireless Wide Area Network - is a form of wireless network. A wide area network differs from a local area network by the technology used to transmit the signal and their size. Wireless networks of all sizes deliver data in the form of telephone calls, web pages, and streaming video.

WWAN uses mobile telecommunication cellular network technologiesto transfer data. It can also use Local Multipoint Distributiuon Service or LMDS and Wi-Fi to connect to the internet. These cellular technologies are offered regionally, nationwide, or even globally and are provided by a wireless service provider. WWAN connectivity allows a user with a laptop and a WWAN card to surf the web, check email, or connect to a virtual private network (VPN) from anywhere within the regional boundaries of cellular service. Various computers now have integrated WWAN capabilities (such as HSDPA in Centrno). This means that the system has a cellular radio (GSM/CDMA) built in, which allows the user to send and receive data.
