1 TORNADO SYSTEM OVERVIEW
MiMOMax Tornado delivers the next generation of high performance true MiMO narrowband remote radios for SCADA,
Protection and Linking applications. The Tornado is the market leader for narrowband throughput and functionality with a full
duplex aggregate data rate of up to 640kb/s in 50kHz in its highest modulation mode.
Tornado radios provide a radio wireless infrastructure for connecting devices used by various applications to form a network
through which IP data, RS-232 serial data or RS485 synchronous serial data can seamlessly flow. Features include isolated
power supply with low power consumption, full duplex operation with built in duplexers and supporting a combination of
interfaces, with very high scalable data rates, remote over the air network management, optional SNMP, ModBus and DNP3
support and a very efficient random-access protocol.
Operating in the licensed frequency bands between 400-470MHz & 806-960MHz, 700Mhz Upper A-Block and VHF, with a
wide temperature operating range and optional waterproof outdoor mount. The Tornado enables unrivalled performance while
maintaining MiMOMax’s renowned reputation for reliability and operational efficiency.
The MiMOMax Tornado radio platform is configurable in three types of system linking, Network Digital Links (NDL), Multi-
Point Digital Links (MDL) and an Optimised Protection Variant (OPV) of the NDL link. The one Tornado radio platform can
be configured differently for the different roles required by these links through the enabling and disabling of features and
functionalities.
1.1 NETWORK DIGITAL LINKS (NDL)
The MiMOMax NDL is a highly reliable and robust point-to-point wireless linking solution designed to support PMR Linking,
SCADA and Backhaul applications.
An NDL link is a simple point-to-point over-the-air connection between two Tornado radios in NDL mode. One is configured
as master, the other as slave. This link allows for very quick data transfer. Modulation can be fixed or adaptive.

Utilizing the MiMO technology and full-duplex operation, this narrowband fixed wireless solution provides a reliable low-error
data transport service. A number of internal interfaces are available to support various SCADA applications and also
multichannel, conventional, analogue, simulcast, MPT, P25 and/or TETRA digital networks in trunked and simulcast
configurations.
For PMR applications, a separate high-quality Network Interface Box (NIB) with up to 6 x 32k ADPCM audio channels plus
9k6 RS232 signalling channel, supports analogue networks.
Multiple links can be cascaded to cope with difficult terrain and very long paths. Different mounting options provide the much-
needed flexibility for varied network requirements. Being fully compatible with the rest of the MiMOMax product types, NDL
can be incorporated into the MiMOMax MDL (point-to-multipoint) linking solution.
NDL links are well-suited for providing backhaul links between sites in P25, DMR and MPT networks. Each link can carry
multiple voice channels (the number varies with the modulation scheme) and have residual bandwidth for maintenance tasks.
A high priority queue is available to provide EF priority to voice and other critical data over the link. The following diagram
shows a simplified two-site trunked P25 network with an NDL link providing the backhaul between the remote site and the
central site.
