This book was released on 2000 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'ATTENTION RECENTE AUX RESEAUX DE TRANSMISSION OPTIQUE EN GENERAL, ET LA CROISSANCE RAPIDE DES RESEAUX D'INTERIEUR SANS FIL OPTIQUE EN PARTICULIER, NOUS MENENT A ETUDIER LES TECHNIQUES DE COMMUNICATION OPTIQUES AVANCEES. DEUX NOUVELLES TECHNIQUES D'ACCES MULTIPLE DE DIVISION PAR LE CODE (CDMA), A SAVOIR, CDMA ENCODE PAR FREQUENCE NON COHERENTE ET CDMA D'HOLOGRAPHIE SONT ETUDIEES POUR ETRE APPLIQUEES AUX RESEAUX DE COMMUNICATION INTERIEURS INFRAROUGES SANS FIL. LA METHODE CDMA ENCODEE PAR FREQUENCE NON COHERENTE EST CONSIDEREE POUR ETRE UTILISEE DANS UN RESEAU LOCAL SANS FIL AVEC LA CONFIGURATION DIFFUSE. UN MASQUE SPATIAL D'AMPLITUDE ET UNE STRUCTURE EQUILIBREE DU RECEPTEUR SONT EMPLOYES AVEC UN RECEPTEUR OPTIQUE CONCU POUR RASSEMBLER LES LUMIERES RECUES DES SURFACES DIFFUSANTES. LA DISPERSION PAR TRAJETS MULTIPLES ET LES METHODES POUR DIMINUER SES EFFETS SONT PRESENTEES. NOUS CONSIDERONS EGALEMENT LES EFFETS DU BRUIT D'INTENSITE ET DU BRUIT DE LA LUMIERE AMBIANTE SUR LES PERFORMANCES DU SYSTEME, EN PLUS DES DIFFERENTES TECHNIQUES POSSIBLES DE MODULATION. UNE DEUXIEME TECHNIQUE, LA TECHNIQUE CDMA D'HOLOGRAPHIE, POUVANT ETRE CLASSEE EGALEMENT COMME UNE TECHNIQUE A ETALEMENT SPATIAL, EST ETUDIEE. LA TECHNIQUE CDMA D'HOLOGRAPHIE A ETALEMENT SPATIAL PEUT ETRE EMPLOYEE EFFICACEMENT POUR ETABLIR UN RESEAU ELEVE DE TRANSMISSIONS MULTIMEDIA A DEBIT BINAIRE ET SUPPORTANT SIMULTANEMENT DES SOURCES ANALOGIQUES ET NUMERIQUES AVEC UN GRAND NOMBRE D'UTILISATEURS ET UN DEBIT BINAIRE VARIABLE. LES PRINCIPES, LA REPRESENTATION MATHEMATIQUE ET L'ANALYSE DES PERFORMANCES DE L'ETALEMENT SPATIAL SONT PRESENTES PAR UNE CONFIGURATION DIFFUSEE PAR ECRAN. DANS CETTE TECHNIQUE CDMA D'HOLOGRAPHIE, LE GAIN DE TRAITEMENT (PG) EST DEFINI COMME LE NOMBRE DE PIXELS DANS UN MASQUE BIDIMENSIONNEL, ET EST INDEPENDANT DU TAUX D'INFORMATION DANS LE DOMAINE TEMPOREL ET DE LA FORME DU SIGNAL DE SOURCE ET SA VALEUR PEUT ATTEINDRE DES VALEURS AUSSI ELEVEES QUE 10 6-10 8. ENFIN, LES AVANTAGES ET LES INCONVENIENTS DE CHAQUE TECHNIQUE SONT ETUDIES ET QUELQUES SOLUTIONS PRATIQUES SONT FOURNIES POUR SURMONTER LES PROBLEMES DE CHAQUE DE CES TECHNIQUES.
Book Synopsis Building Wireless Community Networks by : Rob Flickenger
Download or read book Building Wireless Community Networks written by Rob Flickenger and published by "O'Reilly Media, Inc.". This book was released on 2003 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building Wireless Community Networks is about getting people online using wireless network technology. The 802.11b standard (also known as WiFi) makes it possible to network towns, schools, neighborhoods, small business, and almost any kind of organization. All that's required is a willingness to cooperate and share resources. The first edition of this book helped thousands of people engage in community networking activities. At the time, it was impossible to predict how quickly and thoroughly WiFi would penetrate the marketplace. Today, with WiFi-enabled computers almost as common as Ethernet, it makes even more sense to take the next step and network your community using nothing but freely available radio spectrum. This book has showed many people how to make their network available, even from the park bench, how to extend high-speed Internet access into the many areas not served by DSL and cable providers, and how to build working communities and a shared though intangible network. All that's required to create an access point for high-speed Internet connection is a gateway or base station. Once that is set up, any computer with a wireless card can log onto the network and share its resources. Rob Flickenger built such a network in northern California, and continues to participate in network-building efforts. His nuts-and-bolts guide covers: Selecting the appropriate equipment Finding antenna sites, and building and installing antennas Protecting your network from inappropriate access New network monitoring tools and techniques (new) Regulations affecting wireless deployment (new) IP network administration, including DNS and IP Tunneling (new) His expertise, as well as his sense of humor and enthusiasm for the topic, makes Building Wireless Community Networks a very useful and readable book for anyone interested in wireless connectivity.
