I have both. Wimax at home and Wired at office. I have 1.2 mbps unlimited in Wimax, which is new plan they have increased the speed from 1 to 1.2 for same amount i.e. 2199. My wired line is 1 mbps unlimited.
So, I think I am perfectly competent to answer your question. I am using Wimax since last about 1 year. First of all my personal experience and opinion is I am COMPLETELY satisfied with the same. No complaint whatsoever. Downtime in this 1 year was hardly 4-5 days. So far as download speed is concerned I was consistently getting 120 KBps in 1 mbps and now in 1.2 I get 150 KBps. You cannot ask for more. I am also very much satisfied with CC.
In wired 1 mbps I get speed of 110-115 KBps, which I feel is little lower than Wimax, but considering the price difference, 1499 for wired, you should not have any complaint. Wiredline I am using since last 15 days only so may not be able to say much about downtime, but so far no issue and I hope there should not be any.
I hope this meets your querry.
How do you upgrade to 1.2mbps on wirefree, is it automatic?
