Arrangement first a part that plan of Docomo, divide layers of one 2 GHz LTE network pass, offer pairs of W-CDMA / LTE existence 3 G network of it of service, combine the advantage of enabling the high transmission speed of LTE when LTE network expanded gradually with the news report of the extensive field of 3 G.
LTE foundation famous for remote radio headllows goes to new RRElso of relatively easy and efficient installation of the station of existing W-CDMA basic station. Compared with existing equipment, it helps the weight which it reduces too, size and energy consumption reduce the expenses operated.
For regulate, include one host unit that signal punish and maintain function and RRE basic station that RRE equip, demodulating W-CDMA and LTE signal conveys and gets through the aerial. These two pieces of quilt light-transmitting fibre link.
