This book "could" have been a great book had Mr. Bates proofread it once before publishing it. Having read GSM and GPRS papers before reading this book, I have to say that this book is replete with technical snafus [a case in point for those who suspect is on pg. 30 third paragraph of the Introduction to GSM chapter "paging message sent over PAGCH"] Now anyone with half a brain knows that
1. PAGCH is a GPRS logical channel NOT GSM.
2. It is an Access Grant channel NOT a paging channel which in case of GSM is PCH and PPCH in GPRS.
Now someone new to GPRS would be confused as hell after reading this [I admit I was confused for a couple of minutes too :-), since I am not supposed to be the expert but Mr. Bates was]
Structure wise the book is okay but needs a stringent review of the rambling grammer and the blatant mistakes. IMO its not worth forking 60 bucks. If Mr. Bates is reading this, I adjure you sir to take some time off from your speaking tours and correct the mistakes in this book.
Am giving it two stars for good layout. Taking away three stars for incorrect content.
