Very Honestly speaking, I have had an airtel connection for 8.5 years and never had a speed issue. True to their contention ratio of 1:1, their speed is as promised, had a lot of downtime but that was due to my Belkin Router.![]()
You must be on a leased line to get a contention ratio of 1:1 with Airtel.
I doubt Airtel provides a contention ratio of 1:1 even on shared business broadband lines leave alone shared home broadband. They used to claim 1:1 on their home broadband plan page's but that info' has been removed since quite a while.
Or perhaps you are referring to download/upload speeds which can appear to be symmetrical, but do change every now and then depending on what's going on in their network.
