ALCATEL-LUCENT
REMOTE RADIO HEAD
RRH2X50 800 MHZ (3GPP B26/ 3GPP2 BC10)
The Alcatel-Lucent RRH2x50-08 is a high power Dual Technology Remote Radio Head (RRH) operating in
the 800 MHz frequency band (3GPP Band 26/3GPP2 BC10). The Alcatel-Lucent RRH2x50-08 is capable of
supporting dual technologies (CDMA and LTE) with multiple carriers within 6.725 MHz contiguous BW of
the Band 26 (or 3GPP2 Band Class 10 Blocks C & D) spectrum. It is designed with an eco-efficient
approach, providing operators with the means to achieve high quality and capacity coverage with minimum
site requirements.
A distributed eNodeB expands deployment options by using two components, an LTE Base
Band Unit (BBU) containing the digital assets and a separate RRH containing the radio
frequency (RF) elements. This modular design optimizes available space and allows the main
components of an eNodeB to be installed separately, within the same site or several
kilometres apart.
RRH2x50-08 has two CPRI ports, each port is connected to a Baseband Unit (BBU) (CDMA or
LTE) by CPRI fiber-optic connections carrying downlink and uplink digital radio signals along
with operations, administration and maintenance (OA&M) information. This product is
ideally suited for macro coverage with 50W RF output at each of its antenna ports and offers
multiple-input multiple-output (MIMO) 2x2 operation for a 1.4/3/5 MHz LTE carrier or 2
branch receive diversity for supported CDMA carriers. RRH2x50-08 can be operated in
multiple modes; CDMA carriers only, a mix of CDMA and LTE carriers, or LTE only carriers.
Full benefits of LTE can be realized using the Alcatel-Lucent RRH2x50-08 in distributed
eNodeB architecture and achieve excellent RF characteristics at minimum cost.
The limited space available at some sites may prevent the installation of traditional single
cabinet BTS equipments, leaving coverage holes, or it may require costly cranes to achieve rooftop installation. However, many of these
sites can easily host an Alcatel-Lucent RRH2x50-08, providing more flexible site selection and improved network quality along with greatly
reduced installation times and costs. An external filter may be used to meet stringent FCC emission requirements.
Fast, low-cost installation and deployment
The Alcatel-Lucent RRH2x50-08 is a zero-footprint solution and operates noise free, simplifying negotiations with site property owners and
minimizing environmental impacts. Installation can easily be done by a single person because the Alcatel-Lucent RRH2x50-08 is compact
weighing around 24 kgs can be carried separately and assembled on site, eliminating the need for a crane to hoist the BTS cabinet to the
rooftop. A site can be in operation in less than one day — a fraction of the time required for a traditional BTS.
Excellent RF performance
The compact Alcatel-Lucent RRH2x50-08 can be installed close to the antenna. Operators can therefore locate the Alcatel-Lucent
RRH2x50-08 where RF engineering is deemed ideal, minimizing trade-offs between available sites and RF optimum sites. The RF feeder
cost and installation costs are reduced or eliminated, and there is no need for a Tower Mounted Amplifier (TMA) because losses
introduced by the RF feeder are greatly reduced. The Alcatel-Lucent RRH2x50-08 provides more RF power while at the same time
consuming less electricity.
