Ok.. To get started with.. Data cards - First, for all services whether its 3G/CDMA , all companies provide high speed only upto a certain limit, one can say 10 GB is the average norm. After that you either get very low speeds or you need to recharge (at expensive rates) to continue using high speeds. There is no true high-speed unlimited internet connection here. Secondly, coming to Reliance Netconnect, the speed is good in certain places, terrible at others, so its best to ask the vendor to give a demo at your place or somewhere very close to where you stay to judge correctly. This is true for all providers, not only Reliance. Now, coming to Airtel Wireless broadband. You must be either meaning wired broadband or 3G. If its wired broadband you are ok with, then will speak about that. If its 3G, then again I would go back to what I was saying about data cards earlier, you would get good speeds, but you need to check & its an expensive & not really true unlimited. Either you would get low speeds beyond a limit or need to keep recharging at a high cost.Airtel broadband you can get a wired line & have a wi-fi modem or modem with router
to browse wirelessly in your place. This would hold true for other "wired" connections as well..Not to confuse you & not recommending a brand but there are other wireless providers like Tikona/Wi-5 as well. Need to look for reviews & availability around.
