Dyaptive Solutions

for Wireless Network Operators

With the evolution of 3G and 4G networks, and increased demand for new products and services, many challenges face wireless network operators.

As increasingly advanced data and voice services are released, operators face increasing challenges maintaining service quality.  These challenges come from the high correlation between network performance, capacity, service quality and the load on the 3G networks. Operators need to test the impact on performance and capacity of new features, services, software loads and network equipment. They need to do these tests in their labs, before rolling the services out to customers.

DMTS testing systems let network operators speed service deployment, increase service quality and reduce the cost of problem resolutions. Dyaptive offers proven load testing:

• Validate impact of new services at each stage from service planning through deployment to troubleshooting and field support
• Test new vendor infrastructure equipment under realistic network conditions
• Validate backhaul requirements
• Predict impact of new network configurations
• Plan systems to accommodate peak loads under adverse conditions

The DMTS system lets network operators increase testing capacity - with up to 1000 Software-defined Testing Terminals per rack by automating tests with repeatable, preset test cases and scheduling tools that allow tests to run unattended around the clock. The value of testing is amplified by the sophisticated logging, statistics capture and performance analysis tools.

Functional Application Testing Under Load

Wireless network operators need to be able to predict the impact of new applications and services on network resources. Perhaps more importantly, the impact of such new revenue-generating solutions on the Quality of Experience (QoE) for existing voice and data users must be understood.

Applications and services must be tested under load conditions. Whether the new service is creating the load, or is being introduced on a network that already faces load management issues for the existing subscriber-base, Dyaptive can help operators ensure a high QoE for all subscribers.

• Ensure higher quality of products:
• Find defects that would otherwise make it to market
• Access to logs across all terminals
• Logging of handset/terminal measurements:
• Detailed KPIs captured across hundreds of SDR terminals
• Bring services to market faster:
• Millions of calls/access attempts per hour
• Rapid modeling of multiple scenarios
• Test in ways not previously possible:
• Complex calling/access scenarios
• Random and controlled terminal behaviour
• Mix of real terminals and DMTS traffic

Vendor Verification and Interoperability

In any operator network, there exists wireless RAN infrastructure from a mix of vendors. Often, these vendors arent able to test their released product using the operators own configurations. With releases coming from vendors more than twice a year, conducting complete and repeatable regression tests can be a challenge. Operators need to maximize the amount of time they can spend regression testing within the limited amount of time available to launch new releases.

Dyaptive can provide operators with the ability to create multiple real-world load and stress scenarios in minutes, allowing the optimization and tuning of the vendor equipment, and the comparison/contrast of multi-vendor RANs quickly. Use the Dyaptive DMTS to simultaneously connect with a variety of vendor BTS simultaneously and load to their maxima. Conduct inter-vendor handover tests instantly.

Dyaptive helps operators reduce outages and in-service reconfigurations by finding defects that would otherwise make it to market, and by predicting end-user experiences in the lab environment.

Backhaul Performance Optimization

The optimization and planning of backhaul is a complex and risky venture, and is based on complex mathematical models. Often these models are based upon data simulations as opposed to real load. Theres not only a risk of under-planning backhaul requirements as new applications are deployed, but also a risk of overspending on backhaul for a predicted load before it is needed.

Dyaptive allows operators to test backhaul requirements from real base stations in live-air scenarios, generating real load and stressing a test node to the point of congestion. Dyaptive maximizes data consumption over the radio link, generating millions of transactions each hour, allowing the operator to compare and contrast backhaul capabilities under real world scenarios.

Network deployment and optimization

Predicting the impact of network configuration changes is challenging. Testing configuration changes in live-air networks can be costly and logistically impossible. Operators need a method to both preview the impact of configuration changes, and to forecast the impact of subscriber growth on RAN performance.

Dyaptive helps reduce costs, avoid service interruptions and predict the impact of such load by allowing the verification of network performance under subscriber load without impacting paying subscribers. With the Dyaptive DMTS, operators can fine-tune network parameters and understand the impact of changes in traffic characteristics in the safety of the lab.

Special Projects and Emergency Planning

The impact of increased load on a wireless network that is already under stress is well-known by most wireless network operators. Recent global events have demonstrated the dramatic impact of perfect storm conditions: Massive network demand is placed upon wireless networks in time of emergency, when those network resources may be already under great stress, or experiencing localized outages. Even less dramatic events, such as major sporting events or gatherings can place demands on a network that requires operators to deploy temporary, mobile or emergency RAN infrastructure into the field.

Challenges such as these may be modeled in lab environments using the Dyaptive DMTS. The DMTS can generate hundreds of thousands of voice or data access attempts per hour, creating worst-case conditions and maintaining them for hours or days. Operators can place this load upon RAN infrastructure then model worst-case scenarios in which RAN infrastructure is taken offline, or cycled under crippling load.

Dyaptive can provide operators with the peace of mind that comes from understanding exactly how their network will perform in the perfect storm.
