A member of the Alcatel-Lucent lightRadio
™
family of wireless products. The MRO belongs to
this family.
LTE
3GPP Long Term Evolution wireless standard for high-speed data devices. Evolution implies that
the air interface has evolved from GSM/UMTS standards to an OFDM-based air interface that
realizes peak rates of 300 Mbps downlink and 75 Mbps uplink at less than 5 ms latency. See also
3GPP and OFDM.

O
OFDM
Orthogonal frequency-division multiplexing, the multi-carrier modulation scheme that overcomes
many commonly experienced wireless communications problems, such as multipath and signal
attenuation.

P
PDCP
Packet Data Convergence Protocol, which provides security to both the air interface and the fiber
optic interface of the MRO by compressing and decompressing the IP headers, as specified in the
UMTS protocol stack.

R
Radiall
The proprietary name of an enterprise that produces components for device interconnections.
These components include the R2CT weatherized connector kit by which the MRO installer
retrofits the LC fiber optic connector on the backhaul cable to the SFP port module of the MRO.
The proper name of this company is Radiall USA, Inc. See also SFP.

RoHS
The Restriction of Hazardous Substances Directive, a law enacted by the European Union for
enforcement by its Common Market in order to restrict six particular materials in electrical and
electronic products. These materials are the elements lead, mercury, and cambium, and three
compounds. More broadly, the standard QC 080000 propagates RoHS specifications throughout
the world and thus impacts the choice of regions, nations, and states and provinces selected to
regulate the same substances. The MRO is fully compliant with the RoHS directive.
