Mobile communications is an exciting industry which is full of high-tech terminologies and buzzwords. People in the industry use terms like 3G, 4G, LTE, HSPA, HSPA+, etc. very often but it is not clear for everyone as to what these words really represent. In today's market when it is very common for people to work internationally, having an unclear view of the basic terminologies can lead to misunderstandings. For example, 3G could mean CDMA2000 to someone from the United States, but it may mean UMTS (based on W-CDMA) to someone in Europe. It is especially confusing for those who are relatively new to the industry such as students or new graduates. Why this book?The intention of this book is to save time for those looking for professional information quickly. It means that you don't have to read hundreds of pages to develop a basic understanding of mobile communications. It is written by someone who has already spent a lot of time reading hundreds (or thousands) of pages of academic and professional documentation whilst working full-time in the industry just to come to a simple conclusion: "I wish someone had explained it in fewer words". Hopefully, the ~24 pages of this book give you the basic understanding that you need before diving into the details of mobile communications technologies. The specific aim of this book is to provide a basic understanding of the main technologies used for enabling mobile cellular communications:1GAMPS2G GSMD-AMPSIS-95GPRSEDGE3G UMTSCDMA2000HSPAHSPA+EVDO4GLTE
