I find this pretty interesting. I am RF engineering working as a Manager of Wireless Engineering at Qypsys LLC. I have previous experience with Verizon, Nextel, Sprint, ATT and Ericsson. I am quite interested in where small cells is going. There is an on going debate on whether it will replace DAS systems or just compliment them. I guess it depends on whether or not small cells becomes as functional as macro sites. From my understanding small cells lack some the handover capabilities but I am sure that is being worked out. Any ways, I enjoyed your comments.
