if the vendor quotes compliance to 3GPP Rel 11 in some upcoming version of the product. Medium Fidelity Medium View Now it should be relatively easier to understand what a medium fidelity view should be covering. The duration should be long enough that it covers not just the features planned for the technology in the immediate future, but also for some time in the future. It could be argued that anyone interested in how the roadmap will affect the immediate future (of any commitments that they make) and more would be interested in a medium fidelity view of the same, covering maybe a year or more. It could vary depending on the technology and how soon the business changes roll out, of course. The information graphic in Figure 4-2 gives an idea about medium fidelity medium view in the sense that: It talks about items to be worked on in the next few years (indicated, but not mentioned in the graphic). It also informs about some technology drivers that could be targeted (e.g., data rates up to 500Mbps speeds in uplink, 1Gb/s with low mobility, support for bandwidth of up to 100Mhz). LTE-Advanced roadmap (in mid-2010) Support for wider Bandwidth Relay functionality (up to 100 MHz) Cell edge coverage improvement Downlink transmission Efficiency improvements in rural schemes area coverage Improvements using 8x8 MIMO COMP (coordinated multiple High mobility data rates of 100 point transmission and Mbps and Low mobility data reception) rates of 1 GBps In Downlink and uplink Uplink transmission schemes Others Up to 500 Mbps data rates Local IP Access (LIPA) and Enhanced HNB for traffic offload Figure 4-2. Medium fidelity medium view roadmap example CHAPTER 4 NETWORK ROADMAPS It should also be noted, however, that some of the items indicated in the medium view will overlap with the low fidelity view as they are describing the same roadmap in different ways and would depend on the viewpoint of the reader. Low Fidelity, Fuzzy Abstract Long View As a standard roadmap view, any single picture or graph that tries to capture all
