Abstract In telecommunication systems‚ a generic access network (GAN) is used by cellular device users to connect and interact with other types of communication devices. GAN protocols primarily evolved for wireless communication systems‚ allowing mobile phones to perform functions seamlessly between wireless local area networks (WLANs) and wide area networks (WANs) without interrupting the communication session. Modern GAN technology permits a subscriber to interact via voice‚ data‚ IP multimedia

browsing over wireless networks. An example of 3G technologies is EV-DO. 4G is the generic abbreviation for 4th generation. It is the wireless technology that was designed to optimize data over wireless networks‚ improving the speed and efficiency of data delivery. LTE is one of the technologies that can be used to build a 4G network. This research will compare contrast 3G wireless networks to 4G networks. Compare and contrast 3G wireless networks to 4G networks in terms of: 3G Wide

Network Consultant Scenario IT 240 July 1st‚ 2011 Network Consultant Scenario The answer I selected was C‚ because solution that was proposed does not achieve the required results but does achieve one of the optional results. CAT 5 UTP cables being installed to the current networks will not satisfy the any of the results required or optional. The hub should be replaced by a switch which can support the speeds that some of the equipment can handle in this case is upwards of 100 mbps due

NETWORK ANALYSIS ADVANTAGES Network analysis can be used to assist the planning and management of complex projects. The following are some of the advantages that result from using the technique: • To calculate the total project duration allows businesses to give accurate delivery dates. Customers may insist on a particular completion date and the critical time shows whether the firm can make this date or not. • Calculating each activity allows the operations manager to order special equipment

(FTTH) network seems to be the best candidate. Still‚ as the full deployment of a new FTTH network involves tremendous civil works and costs‚ only the highly profitable areas‚ e.g. city centers‚ are currently being installed. With the installation of such FTTH networks‚ all involved parties stay with many questions. What will the future bring on demands from services‚ upgrades of equipment and maintenance of the new network? What are the next best areas to install and where will an FTTH network require
