The concept of the cellular network on the other hand is much more stationary and focused on a set of base stations that require base controllers and network infrastructure to effectively function. This fixed platform nature of the cellular network approach is juxtaposed with the approach increasingly being relied of using ad hoc networks for enable peer-to-peer communications throughout wireless networks. This aspect of ad hoc wireless network architectures is gaining high levels of interest due to wireless due to WiFi-enabled devices being able to access Facebook, MySpace and other social networking applications. As the ad-hoc architecture inherently supports peer-based communications and is rapidly becoming the foundation of social networking, this type of network architecture is considered highly distributed in nature. Often wireless network providers will have multiple architectures supported within a given network to ensure each role of WiFi users is adequately supported. For the business user the need for a secured connection with IPSEC-level security requires the use of cellular-based networks, yet there also needs to be allowances for creating ad-hoc-based network architectures and topologies to enable social networking. The trade-offs in system architecture are ultimately balanced between frequency spectrums and access techniques. In conclusion, the current state of wireless computing, when analyzed from the context of access techniques, frequency spectrums and...
Basics of the OSI Model and associated documents. Accessed from the Internet on February 12, 2009 from location:
These aspects should be considered while designing and implementing a network to gain maximum efficiency. (Trulove, 19-20) The standard that defines the application of a WLAN is IEEE 802.11 WLAN standard. Though this is the basic standard amended ones define the additional prescriptions added to it like 802.11a or 802.11b. The capacity of a WLAN is defined by its basic compatibility. WLAN of the latest version comes with an 11
Wireless Broadband Technology Overview of Wireless technology Presently it is quite evident to come across functioning of a sort of wireless technology in the form of mobile phone, a Palm pilot, a smart phone etc. With the inception of fast connectivity in the sphere of commerce it is customary and useful to operate from central locations communicating with the remote branches, conducting conferences in remote places, discussing with every body at every
The wireless application models closely follow the internet model. "WAP specifies two essential elements of wireless communication: an end-to-end application protocol and an application environment based on a browser. The application protocol is a layered communication protocol that is embedded in each WAP user agent. The network side includes a server component implementing the other end of the protocol that is capable of communicating with any WAP user agents.
Bluetooth devices use encryption security and this makes the requirement of a "unique key session key to derive per-packet keys thus avoiding frequent key reuse." (Kennedy and Hunt, 2008, p.4) Kennedy and Hunt report that ZigBee is a reasonably priced low energy consumption two-way CDMA/BA-based wireless communications standard which is based on IEEE 802.15.4 which is referred to commonly as a 'Low Rate Wireless Personal Area Networks (LR-WPANs) and which
wireless network technology. Mainly, I will discuss the main features of wireless technology, and explain how network technology has become so useful in the present time. In the next section, I will give a brief review of ten articles and show how they are related to the above theme of the essay. Finally, I will explain the impact of wireless technology within the next decade. In the present section, a brief
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
