Lab-based, end-to-end performancetesting of systems usingPropsim MANET channel emulation

A Mobile Ad-hoc Network (“MANET”) comprises radionodes that dynamically self-organise into randomnetwork topologies. The network confguration

does not rely on any fxed inrastructure and istherefore well-suited to defence and public-safetyapplications. Given the nature of these applications,reliable system performance is critical, which meansextensive and rigorous testing requirements.

Anite’s Propsim MANET channel emulationsolution oers an accurate and efcient methodfor evaluating the end-to-end performance ofradio systems under real-world radio propagationconditions. Developers o radio equipment are ableto signifcantly reduce the need or costly feld trialsby testing the radio link and network performance

in a laboratory environment – this applies realisticmodelling of operating conditions.

Example feld situation



Systematic MANET testing indynamically changing environments

Network-centric security operations require seamless

communications between command centres, vehicles and

dismounted troops to deliver voice and video streams as well

as position data. When communicating on the move, users are

exposed to potential issues relating to radio coverage gaps,continuously changing network conditions and security threats

(e.g. jamming and snifng).

Today’s MANET systems use Sotware Defned Radios (“SDRs”)

and cognitive radio technologies to manage connectivity and

networking. The performance of a MANET greatly depends on

how the waveforms and distributed networking algorithms

perform in a dynamically changing environment where radios

are ultimately deployed.

Radio channel properties such as path loss, delays, power

delay profles, Doppler, intererence rom adjacent radios and

jamming have a critical impact on how the MANET works in the

feld. This is why a systematic testing approach rom link level

to radio groups and larger networks is key to assuring high

perorming, efcient and robust network operation. Testing

various mobility scenarios and terrain types is also important toachieve a well-working MANET system.



Advanced lab-based interoperabilityand performance testing of

Mobile Ad-hoc Networks

Propsim real-world radio channel emulation in your lab

Propsim MANET channel emulation solution effectively

verifes the perormance o single radios and multi-radio

operation in the network. As a lab-based tool, it offers the

ability to accurately and repeatedly emulate propagation and

intererence conditions experienced by the radios in the feld.Early issue detection and resolution offer substantial cost-

savings in the development and testing phases.

• Enables users to test key functionality of critical

communications networks in hardware-in-the-loop test beds

• Offers quick evaluation of mission plans and what-ifscenarios

Propsim MANET channel emulation solution:

• Ensures network reliability through realistic lab-based

testing

• Provides signifcant cost savings by minimising the needor feld trials



Efcient radio device andnetwork level performance testing

From early stage testing to product verifcation

Radio manuacturers and developers use Propsim MANET

channel emulation solution to test and develop the wireless

link and network level performance of radio devices andnetwork functional features.

Examples of these features include:

• Distance delay, path loss and multi-path impact for

evaluating the radio link performance under different radio

channel conditions in the feld

• A selection of waveforms and mechanisms for avoiding

detection and interception

• Network protocols and algorithms to manage adaptive

connectivity and routing of data packets.

Anite’s Propsim Channel Emulators help developers exercise

precise control over testing procedures and run fully repeatable

test cycles or quick issue identifcation and resolution. The

fully automated test set-up enables continuous execution of

regression and quality assurance tests. Incremental product

verifcation throughout the development cycle using realisticfeld conditions helps reveal underlying issues at an earlier

stage. This leads to cost savings and improved product quality.

Assuring interoperability and operational robustnessfor networked communications

Verifying the network’s inter-networking capability, security,

reliability and quality of service is a huge challenge for agencies

responsible for providing radio equipment and networks to thearmed forces. Modern IP packet-based radio systems contain

functions to support mobility at different layers in the network

(such as combat troop radios, tactical data links with airborne

and satellite links). Because o the adaptive operation and

the complexity o the system, accurate feld testing is almost

impossible.

Fortunately, almost all types of tests can be reliably executed

in a lab environment. With Propsim MANET channel emulation

solution, new radio systems can be evaluated and the

interoperability with existing systems can be reliably verifed.

Propsim MANET channel emulation solution offers a systematic

verifcation process that signifcantly minimises the need or

feld trials.

Research and technology development

Researchers work with SDR and cognitive radio technologies

to improve coverage, spectrum utilisation efciency, network

level capacity and security for industrial, commercial as well as

defence applications. Propsim Channel Emulators are widely

used in R&D labs and or applied research around the world.

In addition to supporting MANET testing, Propsim channel

emulators are fully compatible with the latest commercialtechnologies, including WLAN and LTE. This makes Propsim ideal

for developing new technologies and solutions for proprietary

and professional radio systems.

Complex scenarios are easy to create using Propsim’s

comprehensive test scenario creation tools. The user has the

ability to accurately control propagation, mobility and antenna

technology related parameters. Propsim is the only radio

channel emulator that enables virtual drive testing by usingantenna arrays with user-imported radiation patterns in a 3D

propagation environment. Research and development cycles

test different routing algorithms, transmit protocols (unicast,

multicast and broadcast) and recovery mechanisms.

The user can either choose a selection of ready-made testscenarios, engage Anite to create customised test scenarios,

use the in-built test scenario tool or use third party software

applications to create required test scenarios. Propsim runs

arbitrary channel profles or each emulated channel and

MANET link. The process of converting software simulations

to hardware-in-the-loop tests is quick and enables the user to

perform trials in various simulated environments in different

phases of the development cycle.

development work using ready-made and industry-proven

evaluation methods instead of spending time developing

relevant evaluation methods.

Creating a virtual feld environment in the lab

Propsim MANET channel emulation solution creates a virtual

(RF) feld environment in the laboratory, enabling the user to

verify complete products, from end-to-end.

Radio locations and movement are defned in the Propsim

conditions such as network topology, path loss, multi-path,

Doppler and propagation delay, during the test run. The LAN

interface also allows run-time control of link conditions froman external PC. Propsim MANET channel emulation solution
