In choosing to define standards and frequency spectrum levels of this stands, the IEEE LAN/MAN Standards Committee chose to define a very broad public spectrum, which would allow for more efficient use of the standard for LA
and WAN deployments. The IEEE Standards Committee defined the range of 2.4GHz to 5 GHz as the public spectrum band that could be accessed and used for over-air modulation and demodulation. WiFi is the popular term used to refer to 802.11-based networks and their use at the lower ends of the public spectrum band.
The IEEE Standards committee also defined five variations of the 802.11 standard during its initial working sessions in the 1999 -- 2000 timeframe. The initial 802.11a standard was introduced in 1999, having an operating frequency of 5 GHz with a speed of 23 Mbits/second. The 802.11g standard was first introduced in 2003, and supported a 2.4 GHz operating frequency. The standards have progressed rapidly over the last ten years, with the latest protocol designed to support the frequency spectrum levels necessary for supporting large-scale LAN and WAN implementations. An example of this direction by the IEEE Standards Committee is seen in the development and launch of the 802.11n standard with supports frequency spectrum levels between 2.4 and 5 GHz and a transfer rate of 74 Mbits/second. This standard was specifically designed to support real-time messaging, video downloads and high levels of transaction-based traffic throughout LAN and WAN configurations.
The direction of the IEEE standards is to concentrate on creating higher frequency spectrum levels to support greater traffic and broader geographically-based implementations of LAN and WAN networks. Wireless standards have also progressed beyond device-level intelligence to support LAN and WAN architectural constraints and design objectives as well. This is seen in the approach to integrating broadband wireless architectures...
Fourth, as fiber optic lacks conductivity it does not heat up, expand, contract or lose any of its conductivity properties over time. Fiber optic cable therefore has a lower Total Cost of Ownership (TCO) as a result of not having to contend with the continual wear and tear on the metallurgical values of the wire (Ferelli, 23, 24). The Specific Advantages of Fiber Cabling over Copper: Taking a Closer Look It's been
So as to receive the infrared signals, the receivers can be placed at any location within the office space. The spread spectrum WLANs This system makes use of multiple-cell configuration. This is to say that each of the cells in the arrangement is assigned a certain center frequency that is unique and that lies within a chosen band as to eliminate chances of signal interference. The system employs frequency hopping and
Wireless Local Area Network The advent of networking more particularly the Local Area Network has its origin to the growing necessity of the user to have access and share much more data, application and other services than they could otherwise store by themselves in their own computer. Each LAN has to follow a particular topology which depicts physical arrangement of the nodes and logical method by which the data is transferred.
Wireless Networking Phenomenon Today's world is faced with a myriad of challenging and complex issues that require advanced technological solutions. As technology becomes increasingly user-friendly and focused on the consumer, it is evident that users have become more dependent on wireless technological devices as mechanisms that promote convenience, survival, and economic prosperity. Devices such as cellular phones, laptop computers, and personal digital assistants have become absolute essential components for many consumers
This solution will provide the Worldwide Travel Agency with LAN access flexibility and mobility that it lacks in their current wired LAN system. To provide several options on wireless LAN solution, I will compare three different wireless LAN systems of the following three manufacturers. Cisco Systems D-Link From the comparison, it is hoped that the best technical solution for the Worldwide Travel Agency will be selected. After this, the establishment of recommendation,
Networking Wireless Options for the Production Building Lake View Chemicals has made the decision to implement a new wireless networking option for their production building. The requirement to move between different locations within their building to utilize more versatile portable computers as opposed to being mired at fixed workstations is the main objective. As an IT consultant for Aspen IT Services, I feel that as Lake View Chemicals explores the use of
