WCDMA Protocol Structure for Iu CS The WCDMA Iu CS overall protocol structure is depicted in below image. The three planes in the Iu interface share a common ATM (Asynchronous…
Site surveys allow us to measure the level of coverage that the macro network provides the building, check out the details and understand the environment and existing objects in the…
Network planning tools can automate iterative process required for manual planning. In the past few years, there were few tools. Some of them can plan indoor and outdoor networks, or…
After you have defined the requirements for coverage and capacity, the first step in the planning of the internal network is to make an initial assessment of which roofing solution…
Understanding on Motley–Keenan Model for WCDMA Site-specific models of indoor propagation, as the name implies, take the specific characteristics of a particular building as their input. Often these models count…
In particular, for application indoors, it is often desirable to predict the service area of a repeater or microelement based power CPICH. In the repeater installation and commissioning, CPICH power…
