The book is aimed at mobile telecommunication professionals, who want to understand what LTE is and how it works. It is invaluable for engineers who are working on LTE, notably those who are transferring from other technologies such as UMTS and cdma2000, those who are experts in one part of LTE but who want to understand the system as a whole, and those who are new to mobile telecommunications altogether. It is also relevant to those working in non technical roles, such as project managers, marketing executives and intellectual property consultants. On completing the book, the reader will have a clear understanding of LTE, and will be able to tackle the more specialised books and the 3GPP specifications with confidence.
Key features -Covers the latest developments in release 10 of the 3GPP specifications, including the new capabilities of LTE-Advanced Includes references to individual sections of the 3GPP specifications, to help readers understand the principles of each topic before going to the specifications for more detailed information Requires no previous knowledge of mobile telecommunications, or of the mathematical techniques that LTE uses for radio transmission and reception
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.

That time-honored trope: the notion that technology is not the problem, rather, it’s how people use technology that’s the problem is shown to be wanting. Highlighting Marshall McLuhan’s “tetrads” or laws of media as a primary tool of analysis, R.C. MacDougall argues in line with other media ecologists that it’s not so much how we use certain tools that matters, it’s that we use them. More than any other technological form perhaps, communication technologies play particularly powerful and systemic roles in our culture, or any culture for that matter. Late adopters and even abstainers are not exempt from the psychological, social and cultural effects (and side-effects) of modern digital communication technology. While there are certainly varying degrees of immersion –that is to say, while some of us live in the high-rise downtown district, some at the city limits, and still others out in the proverbial “woods”– we all live in Digination today.
