VSAT Networks John Wiley & Sons

Book Description
Now fully revised and updated, VSAT Networks continues to cover all of the essential issues involved with the installation and operation of networks of small earth stations called 'Very Small Aperture Terminal'. VSATs are typically one to two meters in antenna reflector diameter and communicate with one another, or with a central earth station called a 'hub', via a relay satellite in space. This informative volume enables the reader to understand how services, economics and regulatory aspects condition the success of such networks. Key features include: configuration and practical applications of VSAT networks radio frequency (RF) link analysis, focusing on basic formulae and the evaluation of the RF link performance protocols used, with emphasis on the necessary adaptation of protocols used in terrestrial networks procedures for the dimensioning of the network according to the type and volume of generated traffic and to the expected quality of service Written by a well-known, highly respected academic, this authoritative volume will appeal to students of telecommunications, electronics and computer science. Practising telecommunications engineers and technical managers involved in the planning, design and operation of networks and service provision will all find this book a valuable reference source. This Second Edition has taken full advantage of the author's experience gained from the success of the first edition. The theoretical background has been expanded and the operational contents have been updated in view of recent developments in the field.

VSAT NETWORK
Author: G. Maral
Publisher: 1995 John Wily and sons
ISBN: 0 471 953024

VSAT Networks: Second Edition covers all the important issues involved with the installation of VSAT systems. Since the first edition was published, the VSAT market has continued to expand steadily. VSAT technologies have advanced, prompting an increase in the take-up of VSAT services.

Offering a comprehensive introduction to the topic followed by a detailed exploration of multiple access protocols, delay analysis and system dimensioning, this edition is a highly relevant update of VSAT Networks. Written by a well respected and established member of the satellite community, it will be welcomed be academics and engineers alike.

Covers important issues of services, economics and regulatory aspects [*]Provides a detailed technical insight on networking and radio frequency link aspects, therefore addressing the specific features of VSAT networks at the three lower layers of the OSI Reference Layer Model for data communications [*]This timely second edition is fully updated with new figures, improvements and revised chapter on future developments.

This book will appeal to students of telecommunications, electronics and computer science. Practising telecommunications engineers and technical managers involved in the planning, design and operation of VSAT networks and systems will also find this book a valuable reference source

مشكوووووووووووووووووووووور اخوي

الظاهر في مشكله في الملفات اول ملفين نزلتهم لكن فيهم مشكله

اما اخر ملفين دخلت على الموووقع لكن ماعرفت كيف اسوي داون لود

بالله شباب دلوووووني
 


كيفية تنزيل الملفات من موقع رابيد شير rapidshare بالصور
السلام عليكم
الكثير بعانون من مشكلة طريقة التنزيل من الرابيد شير
واغلبية الملفات والبرامج محملة على هدا الموقع
واغلبية الناس حين تظهر لهم صفحة التنزيل يعتقدون ان الوصلة خاطئة.
وهدا شرح بالصور لمن يولجه صعوبة في التنزيل
ناخد مثال
وهده كيفية تنزيل هدا الملف من موقع رابيد شير بالصور
عند الضغط على رابط ملف محمل ب رابيد شير تظهر لك صفحة كما بالصورة التالية:-
13051_1145360512.jpg

بعد الضغط على كلمة free كما بالصورة تتغير الصفحة الى صفحة اخرى كما بالصورة التاليه:-
13051_1145360645.jpg

تنتظر حتى ينتهى العدد ومن ثم تظهر لك هذه الارقام والحروف كما بالصورة التالية :

-
عند كتابة هذه الارقام والحروف بالخانة الجانبية كما هو مشار اليه بالصورة السابقةلم يبقى سوى الضغط على download واستمتع بالتحميل
 


السلام عليكم
ياأخي الملفات كلها تشتغل كويس

حاول مرة اخرى

نسيت انقول ان رابيد شير محدود بعدد معين من الداون لود

تحتاج انك ترجع تستعمل الموقع بعد فترة اخرى
 


مشكوووووووووووووووور اخوي على الشرح

لكن احيانا ما يطلعلي العد التنازلي
 


السلام عليكم

لو انه لايوجد العدد التنازلي يعني انك استنفد المحاولات

حاول مرة اخرى
 
please send me link for solution manual Fundamentals of Power System Economics by Daniel S. Kirschen, Goran Strbac.

I need this urgently
