Nokia wants back into the mobile phone business?

http://www.computerworld.com/article/2912192/nokia-wants-back-into-the-mobile-phone-business.html

This article talks about how Nokia plans to re-enter the cell phone business after selling its mobile phone business to Microsoft. Nokia does e-commerce with Microsoft and have made terms under them with an amount of seven billion dollars, Nokia also does electronic transaction with a Chinese manufacturer and just purchase Alcatel -Lucent for 16.5 billion dollars. Nokia Technologies department already controls patents and wants to rejoin the global smart phone business that is very competitive with companies already well established such as Samsung and Apple. Nokia however are skeptical because of the competitive market of the cell phone business  but believe that they can accomplish this task and gain an advantage with emerging companies.It has not been confirmed just yet but an assumption can be made that they could be building on the Android surface. This move would make sense from a business aspect because Nokia only license novel technology, and would probably license their designs and products to other companies instead of jumping straight back into the cellar phone business. It also appears that their technology does fit inside another maker’s phones.

Questions:

1. How would Nokia re-entering the cell phone business effect other companies?

2. Is Nokia technology networking equipment ready to face global competitors?

3. With Microsoft owning Nokia’s mobile phone business, is Nokia now better equip to expand their brand?
