This is the LTE Macro eNodeB solution , extending its role from the backhaul/enterprise segment to the wireless access segment by offering LTE Base Station capability. With the addition of the LTE Baseband card, it offers a complete TD-LTE Release -9 compliant 2X2 MIMO dual 3-sector Macro eNodeB on a 2 U form factor. The eNodeB protocol processing for the three sectors is handled by the Baseband card while the Remote Radio Head handles the RF up/down conversion. The RRHs are mounted on a tower while the Baseband card occupies one line card slot on the chassis.
