SK Telecom goes for Femto Cell

Source: Light Reading

SK Telecom opted for Femto to manage the exponential growth of mobile data. Barring city states like Singapore, Hongkong, I think most of the Mobile operators will go in the same way as Femto offers a seamless way for end sub.

For the offload, there are various means. Below is a basic setup of mobile network.

[Mobile]--------{Radio network}---------{Core Network}----------{Internet}

If we see, Femto comes in the extreme right hand side. This has a huge positive impact on the Customer experience. i.e. Customer doesn't even have to worry about the technology and he can continue using mobile data.

If we take Wi-Fi offload this is quite similar to Femto, but the key difference is Customer need to activate Wi-Fi and from Operator point of view the traffic may not even reach his network. If the operator is an integrated operator, then perhaps the network can be setup in such a way so that the wi-fi traffic will be routed to mobile data center or network.

For other options like TCP compression, Video compression I am not a great fan of them as these were created during the early days when any home page with size more than 100KB considered bad web design.

I wish to share a detailed analysis if my time permits. Hopefully in the next couple of months..
