This is an interesting development indeed. Intel deserves the benefit of doubt here, I bellieve there is a plan to solidify its position in the back-end cellular networks / C-RAN effort as cited in the article. How ever, I disagree with the analyst's (Brookwood) view that Intel is out to strike some fear into competitors in that space. I have never known Intel to be a patent troll and in this case I believe the acquisition is to safeguard its development efforts in C-RAN.

I am not sure Intel bought this for any purpose than defend itself as it moves into new business segments where it might have not had lots of IPs. With these patents, it can play offense and defense knowing that anyone that attacks it will not see the other cheek. Patent and indeed IP management is a key part of the business now.
