Free space indicates an ideal, even, and isotropic medium of space. When electromagnetic waves are transmitted in this medium, no reflection, refraction, scattering, or absorption occurs. Propagation losses are caused…

Shadow fading indicates the fading brought by obstruction due to a building or a natural feature. Shadow fading changes slowly, and is thus called “slow fading”. Statistics repeatedly show that…

Power boosting in LTE is mainly perform on the Reference signal. However, since the radio power is shared equally by all Resources element, the power allocation for each RE is…

Here I write on simple how guard band requirement for LTE for 2 option. Guard band requirement LTE verses GSM and guard band requirement LTE FDD verse LTE TDD Guard…

Here I write down one basic idea of Spectrum reframing in LTE and why operators require spectrum reframing for LTE. Operators worldwide are looking forward to new LTE technologies deployment…

Choosing which frequency band to operate a LTE network is one of the most critical decision. Operator has to make when it comes to capacity planning. The frequency propagation and…

CN (SAE called EPC) is responsible for the overall monitoring of the UE and the establishment media. Main logical nodes of the EPC are: PDN Gateway (P-GW) Serving GateWay (S-GW)…

NAS procedures, especially procedures for managing connections, essentially similar to UMTS. Main change UMTS is that the EPS allows the union of certain procedures to ensure a more rapid establishment…

LTE access network and E-UTRAN, the network comprises a eNodeBs, as shown in Fig. For the normal user traffic (as opposed to transmission), there is no centralized controller in E-UTRAN,…
