>Initially, carriers hoped to offer four time slots for >the receive mode and four slots for the send mode. Intersting article about the inferior technology. However, four slots for the send mode? Assuming the second slowest coding scheme that would give 53.6 kbs/s. In other words the user would be expected to want to send 3.2 Mb per minute from his handheld? What in the God´s name are these guys thinking? Furthermore, even downwards one slot would be enough. With circuit switched data this 13.4 kbs/s would be on the slow side if downloading mails with large attachments, but with "always-on" packet data the story is entirely different. This is because when you check your mail you don´t do the connection, the mail is already in your phone. Magic. The real speed is 64 Mbs/s (assuming the phone has 64 Mb memory). One time slot down does 49 Mb/h. Question: How many SI threads should be combined to generate that traffic? Answer: one, if Q finally gets some concrete contract in China. - rajala
