This 10 page document discusses mobile measurements of UMTS/HSPA networks in the air. It was created by Justin MA in July 2014 for frequency division duplex systems only. The document does not contain any substantive information on its pages, as they are mostly blank with references to the author and date. It directs the reader to a blog post for additional information on wireless 3G and 4G measurements.
It is a knowledge book of WCDMA mobile geolocation.
For outdoor environment.

The document discusses passive call recording in Asterisk using PRI line tapping. It describes how to configure Asterisk and DAHDI to tap into PRI lines and decode the audio and signaling to allow call recording and monitoring applications without disrupting live calls. Key aspects covered include the need for two spans per line, limitations of the current implementation, and future plans to expand tapping to other protocols like SIP. The overall approach allows building a passive call recording solution using Asterisk by tapping into an existing PRI switch or telco.
Quality of Service (QoS) is an important concept in any network which ultimately leads to network efficiency and customer satisfaction. In this PPT, we deal mainly with the Quality of Service aspects relating to Femto Access Point (FAP) of UMTS technology. PPT mainly deals with the Guaranteed Bit Rate (GBR) implementations.
Atoll is a radio network design tool for LTE planning. It uses the CrossWave propagation model which takes into account morphology data like buildings and clutter classes to more accurately model radio wave propagation compared to standard propagation models like Hata. CrossWave predictions are tuned using results from calibration campaigns to improve accuracy. Atoll also allows for 3D coverage modeling and optimization of heterogeneous networks with different transmitter layers.

LTE uses EPS bearers to carry user data traffic. There are two types of EPS bearers - default bearers and dedicated bearers. Default bearers are created for each PDN connection and provide basic "best effort" internet access. Dedicated bearers provide additional tunnels for specific traffic like VoLTE and can have guaranteed bitrates. Dedicated bearers are linked to a default bearer and inherit properties like the PDN address from the default bearer. GTP is the protocol used to encapsulate and carry bearer traffic through the LTE core network.
This document summarizes a presentation on radio network planning for 3G networks. It discusses key concepts in radio network planning like cell configuration, interference management, frequency reuse, and mobile network evolution. It then covers the specific steps in 3G radio network planning, including dimensioning, nominal planning, simulation, and optimization. The document provides examples of link budget calculations and using planning software to simulate network performance and verify the design meets requirements.
It is a handbook of UMTS/LTE/EPC CSFB call flows.

The document discusses LTE network architecture including nodes like the eNodeB, MME, SGW and PGW, and their functions. It also outlines the basic LTE call flows for initial call setup, detach procedures, idle-to-active transitions, and handovers. Key call flow steps include attach request, authentication, context setup, and establishment of bearers between the UE and PDN gateway.
