Multi Protocol Label Switching (MPLS) is a versatile solution to address the problems faced by present day to day networks. MPLS addresses issues related to speed, scalability, quality-of-service (QoS) management and routing. MPLS can exist over existing asynchronous transfer mode (ATM) and frame-relay (FR) networks. This module explores the concepts of packet switching, IP/ATM overlay model. T......
 

The CAPEX can be reduced by designing the most efficient external distribution system in telecommunication network for telephone service. The fiber optic feeder cable can easily accommodate growth in traffic without the need for installing new cables. This approach is called DLC. This module provides an insight on DLC implementation, network architecture,V5.2 interface, network topologies, serv......
 

Asymmetrical Digital Subscriber Line (ADSL) is one example of xDSL implementation that allows the local copper loop to be used for analogue telephony, broadband data access and IpTV generally called as Triple play. This module is designed to provide an in depth knowledge on ADSL components such as DSLAM, BBRAS and connectivity to ISP. This module discusses ADSL spectrum, local loop performance,......
 

DSL (Digital Subscriber Line) is a modem technology for broadband data access over ordinary copper telephone lines. xDSL refers collectively to all types of DSL, such as ADSL, HDSL, SDSL, IDSL, VDSL etc. This module is designed to provide an overview to DSL family, T1 and E1, features, applications and protocol structure of different types of DSL in use. This module aims to provide a foundation......
 

This module is designed to prepare the participants to understand the concept of data communication, circuit switching vs packet switching, analogue modems, protocols and types of modems. This module also provides an overview to OSI layers, TCP/IP, PPP, PPPoE, PPPoA, ATM and FR. ...
 

W-LAN, WiFi and WiMAX are wireless systems to provide data services on the move as per IEEE standards. These networks can provide broadband wireless access from as low as 10 to 100 mtrs up to 5-15 kms. This module is designed to provide an overview on W-LAN, IEEE 802.11 standards, WLAN Architecture, WiFi standards, WiFi architecture, WiMAX IEEE 802.16a, d, e standard, Data rates, range, technic......
 

Mobility between networks including international cross-border roaming is a normal operation today. The ITU has been working toward developing an international standard for wireless access called as IMT-2000 to worldwide telecom infrastructure. This module is designed to provide an overview of radio spectrum for IMT-2000, new services and capabilities, evolution and migration, IMT-2000 terrestr......
 

Value-added services have unique characteristics and they relate to other services in a completely different way in core network. Subjectively speaking, a value-added service today becomes a basic service and provide benefits that core services can not. This module is designed to provide an in-depth knowledge on functioning of services such as SMS, MMS and their network architecture. This modul......
 

Over 60 percent of the world’s population still not have access to terrestrial wireless service in this era of mobile or broadband data service, one of the enablers of the new telecom infrastructure is Global Mobile Personal Communications via Satellite, or GMPCS. It is a personal communication system that provides a unique technical solution to the limitations associated with terrestrial ......
 

Operators of GSM/GPRS continue to look to UMTS to increase the system capacity and high speed data services. This module provides an overview of the 3G network know as UMTS or W-CDMA and its enhancement HSDPA and HSUPA. The module also provides the key advantages offered by this technology and introduces both the network architecture and the air interface technology. At the end, key challenges ......
 

This module is designed to provide the basic steps involved to install and maintain BTSs in mobile systems. This module targets the field engineers and installation teams. This module discusses the site preparation, power requirements, structural considerations, cabinet installation, earthing and RF cabling. This module provides the procedure to be followed for connecting input power, pre conne......
 

This module is designed to provide an overview for those working in mobile systems to understand the planning aspects, frequency spectrum, sectorisation etc. This module discusses antenna considerations, mounting, orientation and propagation effects. Various planning tools used in cell planning is discussed. This module discusses on link budget, propagation models and planning of channels. At t......
 

Enhancements to the 1x system are needed to offer packet data services at rates greater than 2 Mbps. Network operators are anxious to introduce new services such as broadcast/multicast, Push-to-talk, etc. There are two alternatives for 1x network evolution commonly known as 1xEV-DO (1xEVolution for Data Optimized) and 1xEV-DV (1xEVolution for Data and Voice). This module describes the goals and......
 

CDMA2000 (1x) is designed for increased capacity and packet data services. This module provides an in-depth overview of the CDMA2000 (1x) radio network and the new packet data network. The Radio Access Network (RAN) portion of CDMA2000 (1x) 1x networks is covered at length, including the physical layer, MAC and LAC sub layers. An overview of the CDMA2000 (1x) packet data network, including the ......
