Hallo Experts,

I am considering to opt 4g service from airtel in kolkata. Now airtel is providing wifi router & datacard in same price with the following configs you may find in the following link.

Now i am confused which one to purchase? Datacard or wifi router? I will use only in my home pc or laptop not in any outdoor location. My confusion is whether datacard will give more speed than wifi router as it connects directly with usb drive? Or this is baseless thinking? I will get same speed from my laptop whether it is connected with wifi to wifi router or it is connected with datacard through its usb drive? You may find the specs from the above link. Though my dell xps usb drives are usb3 datacard they are providing is usb 2.

Please help.

    4G operates at a maximum download speed of 100Mbps - although you will be unlikely to acheive anything like that speed in reality. Thus a WiFi connection offering the "N" specification will be as good as a USB/Datacard type connection.

    An additional benefit of the WiFi based router is that it will include a simple firewall and also allow other people to share the connection if you wish.

    A USB/Datacard will only communicate with the Internet at the speed of the 4G connection, so there will be no real benefit in using it.

    The end decision you make should be made on:

    a) If you want to share the connection with others, or would like the added security offered by an additional siple firewall then go with the WiFi router.

    b)If you do not want to share the connection, and the USB/Datacard is cheaper than the Wifi router then go with that.

    Speed wise they will both be the same!

    Thank you for your reply. As per my undestanding wifi router & datacard will provide same speed in laptop. Connect with wifi or connect with usb drive for datacard make no difference in laptop for internet speed. Wifi has some added advantage. So i will go with wifi router.

    Thanks again.
