Radio Protocol Architecture in LTE The EUTRAN radio protocol model specifies the protocols terminated between UE and eNB. The protocol stack follows the standard guidelines for radio protocol architectures (ITU-R M1035) and is thus quite similar to the WCDMA protocol stack of UMTS. The protocol stack defines three layers: the physical layer (layer 1), data … Read more
LTE Possible Dimensioning Concepts LTE network dimensioning involves planning and optimizing various aspects of the network to ensure efficient use of resources and meet performance objectives. Here are some key dimensioning concepts in LTE: Coverage Dimensioning: Cell Size: Determine the coverage area of each cell based on the expected traffic density, terrain, and interference considerations. … Read more
S1 interface – A Single Interface between LTE RAN and evolved packet core The S1 interface is the interface between the LTE RAN and evolved packet core. S1 interface protocol stack is described in Figure. S1 performs the following functions: S1-UP (user plane) S1-CP (control plane) LTE S1-UP (user plane) The S1 user plane external … Read more
Here I write about Iu PS Interface in WCDMA. WCDMA Protocol Structure for Iu PS The Iu PS protocol structure is represented in below image. Again, a common ATM transport is applied for both User and Control Plane. Also the physical layer is as specified for wcdma Iu CS. WCDMA Iu PS Control Plane Protocol … Read more
Margin sites intrusive noise levels due to an increase can be considered as If sites were spaced closer together than position using the same frequency The thermal noise floor. In other words, the system is interference limited as Opposed to limit noise. Often a site link budget maximum range is used to evaluate the process. … Read more
