The book is aimed at mobile telecommunication professionals, whowant to understand what LTE is and how it works. It is invaluablefor engineers who are working on LTE, notably those who aretransferring from other technologies such as UMTS and cdma2000,those who are experts in one part of LTE but who want to understandthe system as a whole, and those who are new to mobiletelecommunications altogether. It is also relevant to those workingin non technical roles, such as project managers, marketingexecutives and intellectual property consultants. On completing thebook, the reader will have a clear understanding of LTE, and willbe able to tackle the more specialised books and the 3GPPspecifications with confidence.
Key features -Covers the latest developments in release 10 of the 3GPPspecifications, including the new capabilities of LTE-AdvancedIncludes references to individual sections of the 3GPPspecifications, to help readers understand the principles of eachtopic before going to the specifications for more detailedinformationRequires no previous knowledge of mobile telecommunications, orof the mathematical techniques that LTE uses for radio transmissionand reception
First, there is a brief overview of the history and development of the spectroscope. This is followed by a short introduction to the theory of stellar spectra. The final parts of this section provide details of the necessary reference spectra required for instrument testing and spectral comparison. It concludes with a chapter covering the various types of spectroscopes available to the amateur.
Next, there is a series of "How to..." sections. These cover all aspects of setting up and using various types of commercially available and home-built spectroscopes. Transmission gratings are covered first, and then more complex models, all the way to the sophisticated Littrow design.
The final part of Astronomical Spectroscopy for Amateurs is about practical spectroscope design and construction. It contains a collection of detailed instructions covering the design and building of three different types of spectroscope, along with the necessary design theory (with minimal math). Developing an instrument in simple steps from the basic grating spectroscope, using standard "off the shelf" adaptors, the author describes how to build spectroscopes equal in performance to the better commercial units, constructed using basic hand tools for a fraction of the cost!
This is the only up-to-date practical spectroscopy book available to amateurs. For the first time, it also brings together an invaluable user knowledge base – a collection of observing, analyzing, and processing hints and tips that will allow the amateur to build up and develop important skills in preparing scientifically acceptable spectral data, which can make a valuable contribution to ProAm (professional/amateur) projects. It covers in detail all aspects of the design, construction techniques, testing, calibrating, and using a spectroscope – enough detail to enable the average amateur astronomer to successfully build and use his own spectroscope for a fraction of the current commercial cost.
This book is an ideal complement to Robinson’s Spectroscopy: the Key to the Stars (Springer 2007) and Martin’s Spectroscopic Atlas of Bright Stars (Springer, due 2009). Together, the three books form a complete package for all amateur astronomers who are interested in practical spectroscopy.
As Professor Chris Kitchin said, "If optical spectroscopy had not been invented then fully 75 percent of all astronomical knowledge would be unknown today, and yet the subject itself receives scant attention in astronomical texts." Olivier Thizy (of Shelyak Instruments, the builder of the LiHiResIII commercial spectroscope) writes on an Internet forum; "What is missing is tutorial books and "how to" books with amateur equipment? I believe spectroscopy is in general moving from builders to users (as CCD cameras did in the 1990's)... ...literature is following but slowly."
This is the practical spectroscopy book that amateur astronomers have been waiting for!
Iridium the satellite system was a mind-boggling technical accomplishment, surely the future of communication. The only problem was that Iridium the company was a commercial disaster. Only months after launching service, it was $11 billion in debt, burning through $100 million a month and crippled by baroque rate plans and agreements that forced calls through Moscow, Beijing, Fucino, Italy, and elsewhere. Bankruptcy was inevitable—the largest to that point in American history. And when no real buyers seemed to materialize, it looked like Iridium would go down as just a “science experiment.”
That is, until Dan Colussy got a wild idea. Colussy, a former head of Pan-Am now retired and working on his golf game in Palm Beach, heard about Motorola’s plans to “de-orbit” the system and decided he would buy Iridium and somehow turn around one of the biggest blunders in the history of business.
In Eccentric Orbits, John Bloom masterfully traces the conception, development, and launching of Iridium and Colussy’s tireless efforts to stop it from being destroyed, from meetings with his motley investor group, to the Clinton White House, to the Pentagon, to the hunt for customers in special ops, shipping, aviation, mining, search and rescue—anyone who would need a durable phone at the end of the Earth. Impeccably researched and wonderfully told, Eccentric Orbits is a rollicking, unforgettable tale of technological achievement, business failure, the military-industrial complex, and one of the greatest deals of all time.

Telecom 101 is composed of three parts: Fundamentals of Telecommunications, Telecommunications Technologies, and the IP Telecommunications Network.
PART I FUNDAMENTALS OF TELECOMMUNICATIONS
2 FUNDAMENTALS OF TELEPHONY
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
6 TRANSMISSION SYSTEMS
7 THE NETWORK CLOUD AND SERVICE PROVISIONING
8 FIBER OPTICS
9 DSL AND CABLE MODEMS: LAST MILE ON COPPER
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.
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.
