Businesses, individuals and public administrations still underestimate the risks of insufficiently protecting networks and information. However, as enterprises increasingly are using wireless devices to create and transmit new data and to access the most sensitive information sitting on their corporate servers, the risks are much greater, the stakes are much higher, and potential loss is much more catastrophic.

In today's society one can communicate with a friend via mail, online chatting, fixed telephone, mobile phones and many other forms of modern technology.

Though the forms of technology are all very different, they all essentially provide the same basic service: person-to-person communication. The

convergence is commonly used in reference to the synergistic combination of voice (and telephone features), data (and productivity applications) and video, onto a single network.

It is a technology that will enable cellular networks to support up to 10 times higher data rate and more users than existing HSxPA networks. It will employ OFDM and MIMO technologies which will allow mobile operators to offer true â&#x20AC;&#x153;quad playâ&#x20AC;? services, i.e., voice, high-speed, IPTV and full mobility.

3G LTE is designed to provide a simple evolutionary path for UMTS operators as they migrate from UMTS to HSDPA to HSUPA and then onto 3G LTE, also called HSOPA. 4G is the successor to the wireless access technologies of the 3G era. To cater to the QoS and data rate requirements of the forthcoming applications such as High Definition TV and DVB, 3GPP and IEEE (which are along the 3GP working groups), have decided that 4G should be very spectrally efficient, should dynamically share and utilize the network resources, have a high data rate and capacity larger than 3G, have smooth handovers across heterogeneous networks, and should be based on an all-IP packet switched network.

Several telecom equipment giants are currently testing 4G communication at 100Mbps while moving and 1Gbps while stationary.

Wireless Sensor Networks â&#x20AC;&#x201C;

â&#x20AC;Ť â&#x20AC;&#x201C; ŘŞ ا ŘŞ اâ&#x20AC;Ź4 Wireless sensor networks (WSN) represent a special subset of wireless networks where the sensors act to collect data, that are to be forwarded to a collection point (a server). Due to the power limitation of such devices, the relatively high attenuation of the propagated signal, and in order to maximize the use of the shared resources, special Access Control and Routing algorithms have been proposed for WSN. Meanwhile, one of the popular applications for WSN is in Location Identification of the objects to which they are attached.
