How Measurement Configuration in EUTRAN

The E-UTRAN can configure the UE to report measurement information to support the control of UE mobility. The following measurement configuration elements can be signaled via the RRC Connection Reconfiguration message. E-UTRAN may configure the UE to report measurement information to support the control elements mobility. Following measurement configuration message can be supplied via the … Read more

How Inter-RAT Mobility performs in LTE

Here I write on How Inter-RAT Mobility performs in LTE, means Handover to LTE and Mobility from LTE. Handover to LTE Procedure for handover of LTE is largely the same as the handover procedure in LTE. The main difference is that the handover to LTE AS a whole-configuration must be signaled, and the LTE it … Read more

Small notes on Connection Re-Establishment Procedure in LTE

Here I write some small notes on connection Re-Establishment procedure in LTE. In a number of cases of failure (eg failure of radio link failure of teaching RLC unrecoverable error, failure of compliance reconfiguration), the procedure for restoring EU RRC connection, provided that security is active. If security is not enabled, when one of the … Read more

LTE Architecture- SERVICE, EPC, E-UTRAN and User Equipment

lets talk about LTE Architecture- SERVICE, EPC, E-UTRAN and User Equipment. In the LTE network is divided into 2 basic networks, namely: 1. EUTRAN (Evolved Universal Terrestrial Radio Access Network) 2. EPC (Evolved Packet Core) SERVICE IP Multimedia Subsystem (IMS) is a good example of cars that can be used in the service layer connectivity Services … Read more

Passive Distributed Antenna Systems in 3G

Passive Distributed Antenna Systems in 3G Various internal antenna solution can meet the different needs of the deployment. DAS solution distributes a plurality of antenna nodes throughout the coverage area. Each antenna assembly can transmit and receive signals 3G. The uplink signals from all the antenna units are collected in a central point, the point … Read more

Active Distributed Antenna Systems inside 3G

Active Distributed Antenna Systems inside 3G A DAS contains the same active components present in a DAS passive, with the addition of active devices such as amplifiers, repeaters or amplifiers bidirectional (BDAS) to amplify and / or radio signals shipping. This enables an active DAS to cover a much larger area of ​​a passive DAS. … Read more

Indoor Link Budget for 3G

Indoor Link Budget for 3G The table shows representative Link Downlink budget for 3G. Fluctuations in the signal can be represented by a scale and small effects such models are typically used for external circulation. Indoor shadowing results in a large-scale signal change, which may be represented by a log-normal distribution in a manner similar … Read more

How to Define on the Basis of Pilot Power Microcell or Repeater

How to Define on the Basis of Pilot Power Microcell or Repeater 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 can be determined by measuring the output (or input) Ec / No and … Read more

Understanding on Motley–Keenan Model for WCDMA

Understanding on Motley–Keenan Model for WCDMA 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 the number of walls, floors or other obstacles between the transmitter and the receiver to produce a value of … Read more

Initial Design of WCDMA Network

Initial Design of WCDMA Network 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 to use. To determine the components of the solution radio, locations macro cell should be analyzed to see if you … Read more
