Product Description: The way that the Internet is accessed has changed dramatically in recent years. In addition to wire line connections such as dial-up, xDSL, cable modems, and optical fiber, wireless implementations are gaining market share based on technologies such as WiFi, WiMAX, MBWA, and satellite and cell phone networks. This thesis provides an overview of Internet access through cellular networks, and especially through the GSM, GPRS, and UMTS networks. Chapter 2 examines the cellular evolution, following the path from first generation (1G) to third generation (3G) and fourth generation (4G) systems. Chapter 3 analyzes the most widespread cellular networks (i.e., GSM, GPRS, UMTS) focusing on their air interface architecture, design, and modulation schemes. It also presents research on cellular data networks, such as VPN, IPv6, and VoIP. Chapter 4 reviews the most popular high-speed mobile internet services, including AT&T wireless, Cingular Wireless, Verizon Wireless, Sprint, Nextel, and T-Mobile. The Cingular Wireless network is tested in terms of speed and reliability by providing Internet access to a laptop through a mobile phone. The analysis shows that, depending on cellular network availability, throughput varied from 5 to 25 Kbps and Round Trip Time (RTT) averaged about 1 second. Also, TCP Timestamps and the Explicit Congestion Notification (ECN) were implemented at the end hosts, thus increasing performance. Chapter 5 discusses performance issues for modern cellular networks, such as RTT and some TCP options. Chapter 6 compares the cellular data Internet connection to wired connections such as dial-up and xDSL/ Cable and with wireless broadband technologies such as satellite, WiFi, WiMAX, and MBWA. The author concludes that as of July 2004, the 2.5G cellular data networks are a reasonable solution for anyone who needs Internet access anywhere that a cell signal is available, and who can afford its high cost.

FAQ'S

1. How do textbook rentals work?
It’s simple. Begin by searching for your textbook by ISBN (10 or 13-digit number that can be found on the back cover of each book), title, author or keyword. Next select how long you would like to rent the book then add it to your cart. Repeat for each book you’re looking for. After completing the order we’ll ship them to you and you’ll also receive a prepaid mailer. Return your books in the mailer by your rental due date.
2. Is renting a textbook better than purchasing it?
We offer both! You can buy or rent the book through Campus Book Rentals. It’s up to you to decide which option best meets your educational needs.
3. How do I track my order?

4. How do I return my books?
When you rent textbooks from Campus Book Rentals you’ll receive a prepaid mailer.

If you don’t receive a mailer you can print a return label from your account. Return shipping is prepaid so please use either of the two methods to ensure they arrive at the correct facility.
5. Can I write or highlight in my book?
Of course! Just remember that future students will rent the same book after you, so please be respectful.

8. Do access codes or other supplements come with a textbook rental?
One time use access codes and other supplemental materials are NOT included with rental books and must be purchased separately.
9. What if I don’t return my rental?
If your book rental is not returned by the due date, your credit card will be charged a non-return fee, equal to the replacement value for the book.
10. Can I purchase my book after I rent it?
Certainty! You’re only charged the difference between what you already paid and the value of the book at the time you initially rented. Login to your account and choose to purchase your book and it’ll walk you through the checkout process.
