Wireless carriers utilize Subscriber Data Management (SDM) systems to consolidate data in a single virtual data store with centralized administration‚ management and reporting. The “Big” part of Big Data comes from the fact that it is a collection of data sets so large and complex that it becomes difficult to process using on-hand database management tools. However‚ Big Data is also unstructured‚ meaning that it does not have a pre-defined data model or is not organized in a pre-defined manner

How safe is your wireless network? Ever since the introduction of the first mobile computer device‚ there has been a growing need and want for more and more mobile computing devices. Once users got the first taste of harnessing the power of the mobile device that was all they needed. Today‚ you cannot walk down any public road or walk into a public building without seeing users talking and connecting to the internet via mobile devices. Today‚ there are two ways that data can be transmitted

Wireless networking is the best networking solution for networking an office. Why? It’s cheaper to deploy; there aren’t any expensive cables to purchase‚ labour for cable pulling through tight conduits‚ purchasing matching socket faceplates‚ purchasing tools and devices for cable repair / troubleshooting. There isn’t any excessive wire clutter‚ no cables running too-an-fro on the desk for computer‚ printer‚ fax‚ phone or PDA. What’s left? A clean desktop with only the mere unnoticeable power

Abramson‚ a professor at the University of Hawaii‚ developed the world’s first wireless computer communication network‚ ALOHAnet (operational in 1971)‚ using low-cost ham-like radios. The system included seven computers deployed over four islands to communicate with the central computer on the Oahu Island without using phone lines. Definition A wireless local area network (WLAN) links two or more devices using some wireless distribution method (typically spread-spectrum or OFDM radio)‚ and usually

As we can see the delay dropped significantly when using PCF. However‚ using fragmentation resulted in different effect in DCF and PCF. In DCF using fragmentation increased the delay as the collisions increased while fragmentation decreased the delay when used with PCF. Using fragmentation in DCF did not affect the load much and it remains nearly the same. However‚ using PCF resulted in load drop and when we used fragmentation with PCF the load decreased even more. As expected‚ the throughput
