Important Safety Instructions for Installers and Users
RF Exposure Information
In order to comply with Federal Communications Commission safety standards for human
exposure to radio frequency (RF) energy, the following precautions must be taken.
2. MOBILE OPERATION
• The user should be fully trained in the operation of the radio, including factors that
influence RF exposure, such as the proximity of people to an antenna during
transmission times.
• Do not operate the voice-enabled transmitters more than 50% of the time.
• Operate the voice-enabled transmitters only when people outside of the vehicle are

1.0 INTRODUCTION
The MCC-6120 SDR PACKET DATA RADIO is used in MCC’s Network. This is an
Extended Line-of-Sight (ELOS), packet switched, digital data network that operates on a single
frequency in the low VHF band (40-50 MHz), a high VHF band (151-162 MHz), or a UHF band
(896-901/935-940 MHz). A network has a cellular structure that uses the programmable MCC6120 SDR as a base station, a repeater and as a remote station. One or more Data Centers are
normally used for the central collection and distribution of data to a customer’s office. The
network can be as small as one base station or may be comprised of thousands of base stations,
repeaters and remote stations. The networks are used for position reporting in mobile
applications (AVL), fixed site data collection (SCADA) and messaging.

The MCC-6120 SDR can be dynamically programmed to operate in three distinct modes: (1) as
a base station, (2) a repeater station, or (3) as a remote station. As a base station it is connected
to a Data Center or Host through a Data Network. The Data Network can be frame relay,
microwave, the Internet or other forms of existing infrastructure. The MCC-6120 SDR has two
Ethernet (10MHz) network interface adaptors. If a direct connection is not available the MCC6120 SDR operates as a repeater into the nearest base station. Multiple repeater links may be
chained together for expansion of the network when no other communication infrastructure is
available. In addition the unit has an 802.11(b) network adaptor that can be used to connect to
PRELIMINARY
MCC-6120 SDR Packet Data Radio Network
PRELIMINARY
802.11(b) access points in the infrastructure mode, or to other 802.11(b) devices in an add-hoc
mode.
As a remote station it can operate as a mobile unit roaming throughout the entire network,
automatically linking with the nearest base station or repeater. When a remote station is installed
at a fixed site it also links itself automatically to the nearest base station or repeater.
The MCC-6120 SDR operates line-of-sight using groundwave. The range of communication by
groundwave is primarily determined by diffraction around the curvature of the earth,
atmospheric diffraction and tropospheric propagation. These ranges are successfully extended
by MCC through the use of robust protocols, sensitive receivers, 100 watt transmitters (low
band) or 30 watt transmitters (high band), and short packetized messages. MBNET200 is the
operating system that successfully integrates these features, providing error-free communication
throughout the network at ranges from 25-50 miles.
The network protocol embedded within the MCC-6120 SDR uses a combination of both carrier
sense multiple access (CSMA) and time division multiple access (TDMA) for achieving a
channel utilization rate greater than 90%.
The MCC-6120 SDR uses GMSK modulation and has selectable data rates of 4.8 Kbps, 9.6Kbps
and 19.2Kbps. Data rates and modulation filtering are limited by internal software to values that
have been type accepted by the FCC for the particular frequency band selected. This prevents
transmitting on an unauthorized frequency or modulation format.
The MCC-6120 SDR has an embedded 32-bit controller for managing all the network functions
associated with a packet switched data network and for interfacing to a variety of peripheral
devices. In addition, it has a built-in test capability that automatically monitors the operating
integrity of the unit at all times. This feature also eliminates the need for any special test
equipment during the installation phase. A laptop, or equivalent, is required to initialize and
operate the MCC-6120 SDR packet radio.
