Specifications

The iRM4451 Intelligent Macrocell Remote Radio Head
(iRRH) is an energy-efficient radio system using lead-
ing-edge multicore processors. It is designed with a
robust, convection-cooled (fanless), IP65 housing for
use in all outdoor environments. In conjunction with
the Altiostar virtual baseband unit (vBBU), the iRM4451
provides a complete intelligent C-RAN solution.
The iRM4451 is capable of providing Macrocellular
(3GPP Wide Area base station) coverage capability with
four transmitters and four receivers (4T4R), and a total
combined transmit power of up to 120W across its RF
ports (four x 30W, or 51dBm). It also supports a lower
power mode with 80W (four x 20 W, or 49 dBm).
The radio transceiver is based on a wideband transceiver
design permitting rapid development of new products
and bands. The design is configured through software
to support all key LTE channel bandwidths, starting
from 5 MHz to 20 MHz. The product incorporates highly
flexible and adaptive DPD and CFR algorithms that
provide excellent linearity and EVM performance. The
receivers offer diversity or MIMO reception with a high
linearity, low noise figure design, that exceeds the 3GPP
requirements.
The iRM4451 has dual, direct-access, IP67 rated fiber
ports. These ports provide data and communications
between the iRRH and the vBBU.
For system synchronization and timing, the Macrocell
iRRH has an onboard GPS receiver. It also has IEEE
1588v2 capabilities that support scenarios where access
to clear sky for GPS is restricted or where IEEE 1588v2 is
the preferred synchronization method.
