The MEB82 SDR MANET Handheld Radio is a portable broadband wireless node designed for emergency response, mobile field teams, UAV communication, remote operations and temporary communication networks where fixed infrastructure may be unavailable or difficult to deploy.
The MEB82-36 radio is based on a software-defined radio architecture and decentralized multi-hop networking technology. Compatible nodes can communicate directly without relying on a fixed central base station, while each radio can participate in routing and relay transmission within the network.
Once deployed, multiple MEB82-36 radios can establish a wireless multi-hop network within seconds. As personnel, vehicles or airborne nodes move, available communication paths can be dynamically adjusted, allowing voice, data, video and positioning information to continue moving across the field network.
MEB82 does not require every field radio to connect through a single central node. Compatible radios can automatically form a decentralized network, allowing personnel to establish communication in locations where conventional cellular, wired or fixed wireless infrastructure is unavailable.
When two radios cannot maintain a suitable direct wireless path, traffic can be forwarded through other available MANET nodes. This automatic multi-hop capability helps extend communication across distributed work areas and supports deployments affected by distance, terrain and physical obstacles.
Field communication networks rarely remain static. Responders move between buildings, vehicles change position and UAVs continuously adjust altitude and direction. MEB82-36 can adapt network routes as node positions change, making it suitable for communication environments where mobility is a normal part of the operation.
The radio is designed to carry more than conventional push-to-talk voice. The same MANET network can transport voice, IP data, real-time video and positioning information, providing a wireless IP transport layer for field communication and situational awareness applications.
MEB82 supports star, chain, mesh and hybrid dynamic networking. The topology can therefore be adapted according to the number of users, operating area, relay requirements and mobility pattern of a project.
Same-frequency networking can support up to 64 nodes, allowing MEB82 radios to be deployed not only for small teams but also as part of larger distributed field communication networks.
Multiple MEB82-36 handheld radios can form a direct mobile mesh network for field personnel. Each unit can operate as an endpoint while also helping forward traffic for other radios when required.
In a compact field deployment, several handheld units may be sufficient to establish local communication between personnel. As the operating area expands, additional nodes can be introduced to provide alternative routes and increase the flexibility of the network.
The handheld radio can be combined with compatible UAV communication modules, portable relay nodes and ground stations. An airborne node can provide an elevated communication point when buildings, mountains or other obstacles limit ground-level radio paths.
This allows UAV video, field data and personnel communication to share a broader mobile network rather than operating as completely isolated wireless links.
In larger deployments, handheld radios can work with vehicle-mounted or fixed-position MANET nodes to extend the field network toward a temporary command post. IP equipment connected on the command side can receive information transported through the wireless mesh network.
This architecture allows the network to expand from a small handheld deployment into a wider field communication system involving personnel, vehicles, airborne platforms and temporary command locations.
The standard operating frequency is 1350–1450 MHz. Frequency configurations from 350 MHz to 6 GHz can be customized according to project requirements, and optional frequency-hopping configurations are available.
Frequency selection should follow the spectrum regulations and licensing requirements applicable to the country or region where the equipment will be deployed.
Channel bandwidth can be configured at 1.25, 2.5, 5, 10 or 20 MHz. This allows system designers to balance available spectrum, communication conditions and required data capacity according to the project.
MEB82 supports adaptive BPSK, QPSK, 16QAM, 64QAM and 256QAM modulation. Different modulation modes allow the radio link to adapt to changing RF conditions while balancing transmission robustness and data capacity.
Maximum specified transmission capability reaches 50 Mbps at 20 MHz channel bandwidth. Receiver sensitivity is specified at -103 dBm at 5 MHz.
Actual application throughput will depend on RF conditions, selected bandwidth, network topology, relay hops, interference and simultaneous network traffic. For video and multi-node deployments, network capacity should therefore be evaluated according to the complete system rather than a single headline data rate.
MEB82 provides multiple antenna and data interfaces for field communication and integration with external equipment. Two TNC interfaces are provided for MANET antennas, while additional interfaces support Wi-Fi, GPS and 5G connectivity.
A 100 Mbps Ethernet interface allows compatible IP equipment to connect to the radio. USB, USB Type-C, TF card, SIM card and SPAD interfaces are also available for power, storage, communication and system integration requirements.
During earthquakes, floods, large accidents and other emergency events, public communication infrastructure may become unavailable, overloaded or unsuitable for field operations. MEB82 radios can be rapidly deployed to create a temporary broadband network between responders, mobile teams and command personnel.
High-rise buildings, underground parking areas, commercial complexes and transport facilities can create challenging radio environments. Handheld MANET radios can work with portable relay equipment and other compatible nodes to build a decentralized communication network for frontline personnel.
The network can provide an IP transport path for operational voice, field video, positioning information and compatible field sensors, helping the command side obtain more timely information from the incident area.
UAVs can be integrated into the MANET network for aerial video and data transmission. Where ground communication is limited by terrain or buildings, an airborne node can also provide an elevated relay position between separated field teams.
Power-line construction, field surveying, inspection and maintenance operations often extend into mountainous or remote areas with limited public network coverage. A mobile mesh network can connect field personnel, temporary command locations and compatible IP devices without first installing permanent communication infrastructure.
Patrol teams operating across changing areas can use self-forming networking to maintain connectivity as personnel move. Voice, live video, positioning and operational data can be carried over the same wireless network according to the application configuration.
MEB82 can also be incorporated into temporary maritime communication networks involving personnel, vessels, shore locations and airborne relay platforms. Multi-hop networking provides additional flexibility when direct links between individual nodes are difficult to maintain.
The MEB82 handheld radio measures approximately 222 × 72 × 40 mm, excluding antennas, and weighs approximately 960 g, also excluding antennas. Its handheld form factor allows the unit to be carried by field personnel while providing broadband MANET networking capabilities.
MEB82-36 is suitable for temporary sites where there is little time to install communication infrastructure. Multiple radios can establish a mobile network quickly and expand network reach by introducing additional nodes where required.
Instead of forcing users to remain within the coverage area of a single fixed access point, the MANET architecture allows network topology to change with field personnel, vehicles and other mobile nodes.
Voice, video, IP data and positioning traffic can use the same broadband mesh infrastructure. This allows a field communication system to support multiple operational services over one mobile wireless network.
A deployment can begin with several handheld radios and later incorporate compatible relay, vehicle-mounted, airborne or command-side equipment as coverage and capacity requirements increase.
Not necessarily. A conventional narrowband two-way radio is primarily optimized for voice communication, while MEB82-36 is designed as a broadband MANET node capable of transporting voice, video, IP data and positioning information. The appropriate system depends on the communication services required by the project.
A universal fixed distance cannot be specified for every deployment. Effective radio range depends on frequency, antenna configuration, antenna height, terrain, buildings, interference, node placement and whether intermediate relay nodes are available. Coverage should be evaluated according to the intended operating environment.
A relay node can be introduced when direct communication is restricted by terrain, buildings, distance or node placement. Relay locations should be selected according to actual RF conditions rather than simply increasing the number of hops, because additional hops also consume network resources.
Multiple IP services can share the mesh network, but the number and quality of simultaneous video streams depend on video bitrate, channel bandwidth, RF conditions, relay hops and other network traffic. Video requirements should therefore be included in the network capacity plan before deployment.
MEB82 provides a 100 Mbps Ethernet interface that can be used to connect compatible IP equipment. The practical integration of cameras, computers, sensors or other network devices depends on their IP configuration, application protocols and bandwidth requirements.
No. UAV relay is mainly useful where increased antenna height can help overcome terrain, buildings or separated operating areas. For smaller or less obstructed sites, handheld, portable or vehicle-mounted MANET nodes may provide the required network connectivity without an airborne relay.
Project planning should normally include the deployment country, available frequency band, number of nodes, operating area, terrain, mobility requirements, expected video and data traffic, battery requirements and whether handheld, vehicle-mounted, relay or UAV nodes will operate together.
