System and antenna for radio access networks
First Claim
1. An active antenna including at least one sector and a plurality of radiofrequency sub-modules operating synchronously for radiofrequency transmission and reception of high power output signals, each radiofrequency sub-module including a radiating antenna element, low power amplifiers for uplink and downlink, up/down conversion, digital to analogue conversion and filters adapted to process a certain part of the high power output signal, the active antenna comprising:
- a first set of n modules (Mi), i=1, 2, . . . , n, and a second set of m modules (M′
j), j=1, 2, . . . , m, both sets of modules (Mi, M′
j) using a same hardware platform and each set of modules (Mi, M′
j) integrating radiofrequency sub-modules;
a digital platform comprising;
a set of base-band modules for base-band processing and operating in at least one radio access technology selected from 2G, 3G and LTE;
processing means for control plane of 2G and 3G radio access networks; and
routing means for data relay from/to a core network in accordance to an standard interface selected from lu, Gb and S1; and
at least an Ethernet connection to the core network;
a power supply connection;
at least two optical ports for connection in chain with sectors of a pair of active antennas; and
an IP address assigned thereto.

Abstract
An active antenna with an IP address including a first set of modules (Mi) and a second set of modules (M′j), both sets using a same hardware platform and each set integrating radiofrequency sub-modules. Further including at least an Ethernet connection to the core network for providing the active antenna with capability of operation from an anchor site, and a digital platform integrating a set of modules for base-band processing, operating in one or more of 2G, 3G and LTE technologies. The active antenna includes processing apparatus for control plane of 2G and 3G radio access networks, routing apparatus for lu, Gb or S1 data relay from/to the core network to provide the active antenna with capability of operation from a relay site. Further included is at least two optical ports for connection in chain with a pair of active antennas in the same relay site and a power supply connection.
