What is the user speed in 3G networks? For example if there is 5Mbps in downlink, is that mean that these 5Mbps will be divided among users. So if we have 5 users they will have download speed about 1Mbps. Does introducing more scrambling codes, channels or channel elements have any impact on user speed. How can we calculate user speed in 3G (UMTS/HSDPA) network??
Yes you can achieve 7.2 even 14.4 Bbps, but: 1st- in the case if the node B is configured correctly and enough transmission capacity between Node B and RNC and the licence (from vendor)is allowed to achieve this kind of speed. 2nd- there should not be any more heavy UEs on the cell, Cause 14.4Mbps is given for the Node B, it’s up to you how you will use the capacity, means you can give some threshold for UEs and increase the code capacity. 3rd depends on you UE or modem, means usage of code is different on each UE or modems.
