El curso de Tecnología de Redes Inalámbricas presenta al estudiante las diferentes técnicas y estándares actualmente utilizados para la transmisión de datos a través del aire usando estándares como 802.11, Bluetooth, Zigbee, Infrarrojo, etc. Frente a tal variedad de posibilidades para la organización de las prácticas de la asignatura, hemos considerado el uso de un sistema de Desarrollo Abierto que sea lo suficientemente versátil como para adaptar módulos que permitan la prueba de las diferentes tecnologías de redes inalámbricas existentes, por esta razón ha sido elegido la plataforma Arduino, lo que nos permitirá agregar módulos adicionales (Shield) con suficiente adaptación al tiempo de práctica. Arduino es una familia de microcontroladores y un entorno de creación de software que facilita la creación de programas (llamados bocetos) que pueden interactuar con el mundo físico. En el caso de este libro, la idea es usar Arduino con diferentes versiones del estándar Bluetooth. El libro está dividido en diez proyectos y, al final del libro, en el Anexo I, aparece el código fuente de la mayoría de estos proyectos.

An eye-opening account of how the hidden rise of personalization on the Internet is controlling-and limiting-the information we consume.

In December 2009, Google began customizing its search results for each user. Instead of giving you the most broadly popular result, Google now tries to predict what you are most likely to click on. According to MoveOn.org board president Eli Pariser, Google's change in policy is symptomatic of the most significant shift to take place on the Web in recent years-the rise of personalization. In this groundbreaking investigation of the new hidden Web, Pariser uncovers how this growing trend threatens to control how we consume and share information as a society-and reveals what we can do about it.

Though the phenomenon has gone largely undetected until now, personalized filters are sweeping the Web, creating individual universes of information for each of us. Facebook-the primary news source for an increasing number of Americans-prioritizes the links it believes will appeal to you so that if you are a liberal, you can expect to see only progressive links. Even an old-media bastion like The Washington Post devotes the top of its home page to a news feed with the links your Facebook friends are sharing. Behind the scenes a burgeoning industry of data companies is tracking your personal information to sell to advertisers, from your political leanings to the color you painted your living room to the hiking boots you just browsed on Zappos.

In a personalized world, we will increasingly be typed and fed only news that is pleasant, familiar, and confirms our beliefs-and because these filters are invisible, we won't know what is being hidden from us. Our past interests will determine what we are exposed to in the future, leaving less room for the unexpected encounters that spark creativity, innovation, and the democratic exchange of ideas.

While we all worry that the Internet is eroding privacy or shrinking our attention spans, Pariser uncovers a more pernicious and far- reaching trend on the Internet and shows how we can- and must-change course. With vivid detail and remarkable scope, The Filter Bubble reveals how personalization undermines the Internet's original purpose as an open platform for the spread of ideas and could leave us all in an isolated, echoing world.

Chapter List

Telecom 101 is composed of three parts: Fundamentals of Telecommunications, Telecommunications Technologies, and the IP Telecommunications Network.

PART I  FUNDAMENTALS OF TELECOMMUNICATIONS

1 INTRODUCTION
2 FUNDAMENTALS OF TELEPHONY
3 SWITCHING
4 THE TELECOMMUNICATIONS INDUSTRY

We begin with the fundamentals of telephony and the telephone network – the basis for understanding everything else.

First is the Public Switched Telephone Network (PSTN): loops and trunks, circuit-switching, analog, the voiceband and Plain Ordinary Telephone Service (POTS). Plus, new for the fourth edition: Voice over IP (VoIP) is now part of the fundamentals.

Next is switching, starting with traditional telephone switches: Centrex, PBX and PBX trunks, and how that relates to the newer ideas of softswitches, Hosted PBX and SIP trunking.

This part is completed with a chapter on the telecommunications business: Local Exchange Carriers and Inter-Exchange Carriers, ILECs and CLECs, the main players and how carriers interconnect.

PART II TELECOMMUNICATIONS TECHNOLOGIES

5 DIGITAL
6 TRANSMISSION SYSTEMS
7 THE NETWORK CLOUD AND SERVICE PROVISIONING
8 FIBER OPTICS
9 DSL AND CABLE MODEMS: LAST MILE ON COPPER
10 WIRELESS

The second part is devoted to telecommunications technologies: the actual methods used to implement circuits and services.

We begin with digital: what digital is, how voice and video are digitized, and how digitized information is actually transmitted.

The next chapter is transmission systems: the high-capacity systems developed to carry many users’ traffic. This starts with the installed base of channelized systems, the hierarchy of DS0, DS1 and DS3 rates and an overview of T1, T3, SONET and ISDN.

Then our attention turns to the new generation packetized systems, introducing the concepts of overbooking and bandwidth on demand instead of channels, how this is implemented with frames and packets, coexistence and transition from channels to packets.

Then we understand the “Network Cloud”, how services are actually implemented, the three basic types of services and the equipment used for each.

Completing this part are chapters on the technologies used to implement the network:

Fiber Optics, including fundamentals of fiber, wave-division multiplexing, the network core, Metropolitan Area Networks, Passive Optical Networks and fiber to the premise.

Last Mile on Copper: DSL and Cable Modems, including fundamentals of modems, DSLAMs, VDSL, broadband and cable modems.

Wireless, concentrating on mobile communications: cellular and mobility concepts, the technologies TDMA, CDMA and OFDM, the generations from 1G to 4G, and the systems GSM, UMTS, 1X and LTE. This chapter is completed with WiFi and satellite.

PART III THE IP PACKET-SWITCHED TELECOM NETWORK (IP-PSTN)

11 "DATA" COMMUNICATIONS CONCEPTS
12 CODING, FRAMES AND PACKETS
13 THE OSI LAYERS AND PROTOCOL STACKS
14 ETHERNET, LANS AND VLANS
15 IP NETWORKS, ROUTERS AND ADDRESSES
16 MPLS AND CARRIER NETWORKS
17 THE INTERNET
18 WRAPPING UP

The third part of Telecom 101 is dedicated to the new-generation IP telecommunications network.

We begin by understanding how convergence was achieved by treating voice and video like data – then accordingly, cover the fundamentals of what used to be called “data communications”: DTEs, DCEs, LANs and WANs and the crucial concepts of packets and frames.

There are so many functions that need to be performed to implement phone calls, television, web browsing, email and everything else over the IP network, a structure is necessary to be able to identify and discuss separate issues separately. For this purpose, there is a chapter on the OSI Reference Model and its layers, identifying what the layers are, examples of protocols for each layer and how they work together in a protocol stack.

Then we begin moving up the layers. The next chapter is on Ethernet, LANs and VLANs (Layer 2), including MAC addresses and MAC frames, LAN cables, Optical Ethernet, LAN switches and how VLANs are used to separate traffic.

The next chapter is all about IP (Layer 3): how routers implement the network, routing tables, IP addresses, subnets, IPv4 address classes, static addresses, dynamic addresses and DHCP; public addresses, private addresses and NAT; and an overview of IP version 6.

On a real-world telecom network, a traffic management system is required. This is implemented with a technique called in general virtual circuits, and in particular with MPLS. The next chapter in the book covers the fundamentals, briefly reviews legacy technologies X.25, Frame Relay and ATM, then focuses on MPLS and how it is used to implement VPNs, Class of Service, service integration and traffic aggregation.

The last main chapter is on the Internet: its origins, what an ISP is and how an ISP connects to the rest of the Internet via transit and peering, the web, the Domain Name System, HTML and HTTP, SSL, MIME and base- 64 encoding for email, Internet telephony and Internet VPNs vs. business customer “MPLS service”.

The final chapter is a summary and wrap-up, covering technology deployment from the top down, useful reference charts listing all of the technologies, standard network designs and ending with a look at The Future.

APPENDICES

Telecommunications technology is in constant change – and some technologies that used to be of prime importance are not so important today, and so have been moved from the main part of the book into appendices. 

The very last part of the book provides a comprehensive list decoding mainstream acronyms and abbreviations used in telecom.
