As well as these obvious benefits, mapping out everything during technical and applications planning also enables the organisation to identify the specific benefits it is looking for from the availability of fast data. Once both the technical plans and application plans are ready, it becomes easy to find crucial information such as the frequency spectrum needed and the estimated cost of building higher-speed capabilities and introducing the higherspeed data applications. With this information, EADS can make a budgetary offer for the necessary Fortecor applications. In effect, new, data-centric operational models can be developed. For the best results, organisations should look at the planned applications and see if operational models will have to be redefined. Service level definitions and coverage plans should also be cross-checked. In addition, service levels need to be defined for each application. Organisations need to define the necessary applications and their integration requirements. Applications planning The primary goal of applications planning is to prepare for the introduction of the applications that take advantage of faster data and more extensive capacity. With the information from these four key aspects of the network, EADS can make a budgetary offer for the necessary Fortecor® technology solutions. Network upgrade requirements identifies the status and possible gaps in network elements and system software, as well as radio capacity.Service levels looks at how wide, reliable and fast future data solutions should be.Transmission checks the status and any possible gaps in the fixed transmission network.Coverage outlines the coverage area(s) for fast data.Planners must map the route from today's network to tomorrow's faster network, especially in the following four areas: Technical planning Technical planning will identify any gaps and special requirements in terms of technology. The two planning activities will typically run in parallel. Technology planning will provide the platform for high-speed data, while application planning will provide the operational tools to reap real rewards in terms of improved efficiency and working practices. Solutions 9 Time to prepare for faster data Any organisation looking to take its first steps towards a future involving high-speed data will need to start making plans in two fundamental areas. And thanks to increased data throughput, Fortecor effectively saves spectrum. However, efficient countermeasures for these challenges have been designed for Fortecor ® solutions. For example, any given slice of the spectrum could only carry half as many 50kHz carriers as 25kHz carriers. In addition, increasing the bandwidth means that fewer carrier channels fit into the available frequency band. In other words, the same radio signal does not carry as far as before. And although the new modulation techniques such as QAM can be very effective, the higher modulation levels that yield the best bit rates (QAM 16 and QAM 64) also decrease the signal. A wider channel has more noise than a narrow one, so using a 50kHz channel instead of a 25kHz channel, for example, means that at the edge of the cell, the signal is more difficult to "hear" clearly. These advances are great, but they also entail certain challenges. For example, TEDS and WiMAX networks both use a technique called QAM (Quadrature Amplitude Modulation). ![]() ![]() In addition to wider carrier channels, new modulation techniques can be used to pack more data into the same signal. Using a 50kHz channel would yield twice as much space to transmit information, while a 150kHz channel could yield six times as much. For example, TETRA networks currently use carrier channels with a bandwidth of 25kHz. Increasing bandwidth gives more space for data, and modulation packs the data tighter. Data can move faster through a network by changing two things: the bandwidth and/or the modulation. What makes these so-called high-speed networks appear faster is that they can carry more data through the network at one time. The radio signals in wideband or broadband networks do not actually propagate any faster than in narrowband networks. But data speed is only one part of the equation, so what are the other important parameters? Key Touch gets back to basics. 8 technology How Fortecor ® scales the towering heights of increased data speeds Future radio communications will require faster data.
