OAM 3G Network Ericsson discusses operation and maintenance of Ericsson's 3G radio access network. Session 1 covers the OSS, EMAS and other tools used for network operation. Session 2 discusses commissioning radio base stations, replacing modules, backing up network nodes, and upgrading base station capacity. Key tools include OSS, EMAS, element manager and scripts for configuration tasks. Proper planning, tools and procedures are needed for tasks like commissioning, module replacement, backups and hardware upgrades.
LTE-BASICS-ppt .ppt
Mobile data traffic is growing exponentially due to increased mobile internet usage. LTE was developed as the next step to address this growth by providing significantly higher data rates, lower latency, and improved system capacity over 3G networks. LTE uses OFDMA for downlinks and SC-FDMA for uplinks to achieve higher spectrum efficiency. It supports bandwidths from 1.4MHz up to 20MHz and can operate in paired and unpaired spectrum. The LTE architecture separates the radio access network and core network functions.

The document discusses the evolution of mobile networks from 3G to 4G and 5G, and provides an overview of SKY Network's plan to modernize its radio access network (RAN). The modernization will involve deploying 4G and 5G radio nodes across different scenarios, including replacing existing 3G nodes with 4G/5G, deploying new 4G-only nodes, and using indoor small cells. The interfaces, architectures and equipment involved are also described at a high level.

This document provides instructions for integrating a baseband 521x into an OSS RC, RNC, BSC network. It describes the various configuration types for new and existing sites. The procedure includes preparing tools and software, installing hardware, integrating the baseband into the RNC and OSS, setting licenses, and configuring primary/secondary and external alarm settings. It aims to commission and integrate the baseband while following standard processes.
FPGA_Logic.pdf
The document discusses the structure and design flow of FPGAs. It describes how HDL code is synthesized to FPGA primitives which are then mapped and placed onto configurable logic blocks and routed. It discusses the components within configurable logic blocks including lookup tables (LUTs), multiplexers, and flip flops. It provides examples of optimizing logic using these resources such as implementing adders and multiplexers more efficiently.
DWDM-Presentation.pdf
This document provides an overview of Dense Wavelength Division Multiplexing (DWDM) technology. It discusses the concepts of fiber optics, wavelength division multiplexing, bandwidth demand over time, and options for increasing bandwidth capacity such as TDM and WDM. It also describes DWDM components like transponders, multiplexers/demultiplexers, optical add/drop multiplexers, and erbium-doped fiber amplifiers. Finally, it discusses the evolution of DWDM technology and its benefits for optical networking.

VHDL summary.pdf
The document provides examples of various VHDL constructs including entity declarations, architecture bodies, components, signals, constants, data types and objects. It shows how to describe synchronous and asynchronous logic using processes, and how to translate a state flow diagram to a two-process finite state machine description. Key constructs demonstrated include entity and architecture declarations, port maps, processes, if/else statements, case statements and sequential signal assignments.
ROM PAL PLA.ppt
This document discusses digital system design topics including tristate buffers, read-only memories (ROMs), and programmable logic devices. It covers how tristate buffers can output high, low, or high-impedance signals. ROMs are introduced as memory devices that can only be written once but read many times. Programmable logic arrays (PLAs) and programmable array logic (PALs) implement logic functions using a sum-of-products expression. More complex programmable logic devices (CPLDs) and field-programmable gate arrays (FPGAs) allow many logic functions to be programmed on a single chip.
Lecture 16 RC Architecture Types & FPGA Interns Lecturer.pptx
The document discusses reconfigurable computing architectures and FPGA internals. It covers two main types of reconfigurable computing - microprocessor-based using dynamically joined multi-core processors, and FPGA-based using programmable logic blocks connected to processors. The internals of FPGAs are described including lookup tables, logic blocks, and configurable logic blocks. Performance evaluation considers mapping designs to logic blocks and calculating timing.
