Optical fiber communication system Important paper
This document provides an overview of optical fibers, including their evolution, structure, working principles, classification, communication systems, advantages/disadvantages, and applications. It discusses how optical fibers were developed from the 1880s to become the backbone of long-distance phone networks in the 1980s. The core and cladding structure is explained, as well as how total internal reflection guides light through fibers. Applications include telecommunications, space, broadband, computing, industrial, medical, and military uses.
GPRS telecommunication
GPRS was established by ETSI to provide packet-switched data services in GSM networks. It introduces two new core network nodes, SGSN and GGSN, to route packets between external data networks and mobile stations. GPRS supports bit rates up to 170kbps and quality of service features. It allows dynamic allocation of radio resources and efficient delivery of packet data using concepts like always-on connectivity and burst transmissions. GPRS uses concepts like point-to-point and point-to-multipoint connections to provide services like IP, X.25, SMS and other applications to mobile users.
Gprs 110901034127-phpapp02
GPRS (General Packet Radio Service) improves upon existing cellular data services by using a packet switched network rather than a circuit switched network. This allows for more efficient use of network resources and bandwidth. GPRS supports IP and X.25 networks and provides higher maximum data rates and shorter connection times compared to previous technologies. GPRS mobility management includes procedures for attachment, detachment, and tracking a user's location as they move between different areas covered by the network.

introduction-to-gprs-egprs-
Here are the key points about GPRS main concepts:
- GPRS uses packet switching rather than circuit switching, allowing variable bit rates rather than a fixed 9.6 kbps rate.
- Radio resources are shared statistically between users through dynamic allocation of timeslots. This allows optimization of resource usage.
- Variable coding schemes allow bit rates from 9 kbps up to over 150 kbps depending on radio conditions and number of timeslots allocated.
- Resources are only used when data is being sent, through the establishment of temporary block flows (TBFs).
- One timeslot can be shared by multiple MSs through time multiplexing controlled by the BSS.
- The transmission rate per radio resource is variable depending on channel quality
Satellite communication
Satellite communication uses satellites placed in orbit around Earth to relay radio signals between Earth stations. Satellites allow communication across large distances and any location. The first communication satellite was launched in 1958. There are different types of satellite orbits including low Earth orbit, medium Earth orbit, and geostationary orbit. Satellite communication is used for television, radio, telephone, internet, weather monitoring, and tracking resources. While satellites provide wide coverage, their operation has high costs and technological limitations.
Simulation of OFDM modulation
This document discusses simulation of OFDM modulation adapted for fixed image transmission over disturbed channels. It presents results from a MATLAB simulation of an OFDM system using various modulation schemes (BPSK, QPSK, 16PSK, 256PSK) with and without convolutional coding. The system is evaluated based on received image quality, SNR, BER, and other parameters when using a standard guard interval of 25% of the symbol period versus a modified shorter guard interval. Results show image quality of 98% can be achieved with the classic OFDM system using a 25% guard interval when convolutional coding is added to improve transmission quality over noisy channels.
