Why is Airtel Shouting 4G Network Can Offer Max 40Mbps?

Many people are asking a question regarding Airtel 4G launch, that is why Airtel is saying its LTE-TDD network can provide upto 40 Mbps downlink and upto 20 Mbps uplink while most of LTE carriers over the globe are shouting about 100Mbps speed.

With Airtel's promise to deliver upto 40Mbps downlink, I checked out that during launch events at Kolkata Airtel 4G delivered around 32Mbps, while at Bengaluru launch event it was around 38Mbps as speedtest.net results say. But upload speed is not so good, on average 8Mbps.

After weeks of Airtel 4G launch at Kolkata, I got an opportunity to try out Airtel 4G. That was kind of real time test zone, as there was another 4 people accessing Airtel 4G along with me. I got around 1.9MiB/s ~ 16Mbps. That is pretty good.
