Product Description: This book explains how the GSM system has been modified to provide GPRS, EDGE, and EGPRS mobile packet data services. Explained are the GPRS and EGPRS packet control channels and gateways to the GSM system to provide a maximum delivered packet data transmission rate of approximately 474 kbps. You will learn how EDGE is an evolved version of the GPRS radio channel that uses new phase modulation and packet transmission to provide for advanced high-speed EGPRS data services. The GPRS system allows cellular service providers to upgrade one or more GSM radio channels (with changes) to provide broadband medium-speed and high-speed data services to their customers. GPRS and EGPRS technology is an "always-on" system that allows users to browse the Internet without complicated dialup connections. You will discover that the key types of GPRS and EGPRS devices include external radio modems, wireless PCMCIA cards, embedded radio modules, and mobile telephones. External radio modems allow the customer to simply plug in their GPRS device to their USB or Ethernet data port to their desktop or laptop computer. GPRS PCMCIA cards can be added to most laptop computers or embedded radio modules allow devices such as PDAs and Laptops to integrate high-speed wireless without adding PCMCIA cards. Some mobile telephones include both GSM (voice and low speed data) and GPRS (high-speed packet data) capability. Because the needs of voice and data communication are different, the operation of the GSM radio channel is different. GPRS devices can have single mode (only GPRS/EGPRS) or dual mode (both GSM voice and GPRS data) capability. You will discover how the GPRS system was modified using EDGE technology toincrease the 171.2 kbps GPRS maximum data transmission rate to 474 kbps EGPRS data transmiss

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?
Login to your account here, you’ll see your current rentals listed textbook rentals listed with a yellow box that says “track”. Click the box to view the tracking number. *Not all books will have a tracking number since they may be sent from one of our partners. Tracking numbers will be updated as they become available.
4. How do I return my books?
When you rent textbooks from Campus Book Rentals you’ll receive a prepaid mailer. When it’s nearing your due date you’ll place your books inside the mailer and take it to the nearest USPS drop box or Post Office. 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.
6. How much money can renting my books save?
It depends on the book. Generally renting textbooks can save you up to 80% compared to a new textbook.
7. Are Campus Book Rentals’ books the same as my bookstore’s?
Yes! We only ship US edition textbooks, which are the same as your campus bookstore.
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.
