3G / LTE Testing
Most 3G / LTE deployments are likely to be upgrades, so the equipment and services need seamless compatibility with incumbent network technologies. Consumers selecting the device will expect it to work on the first day of service deployment, so the secret to success will be the testing of network components and devices, with comprehensive verification during the design, development, and deployment phases.
Major potential pitfalls include call drops, network resource outages, and poor quality of service (QoS), which would mean that real-time voice or video signals are not getting priority over lower priority data, such as texting. Poor QoS can result in jagged video, degraded audio, or an application time out on a web page. And, an overall poor QoE can result in subscriber churn and lost revenue.
Like previous technology adoptions, successful companies are turning to mobile testing to clear the way for robust network deployment and ultimately satisfied customers.
- Avoid Dropped Calls
To ensure consistent service, the mobile network needs a fully functional and innovative backhaul network as well as high performance receivers that support multiple-in multiple-out (MIMO) technology, a hallmark of the mobile network specification.
- Keep Networks Online
As new mobile network services are installed in legacy systems, network operators need to validate overall network and device performance as well as interoperability between new and legacy infrastructure equipment in an environment of increased technological complexity.
- Ensure QoE
It is important to consider the entire network, including the backhaul, the core, and the device, to ensure that all elements operate together and that the data rates match the mobile network specification. Robust QoE along with QoS testing can give service providers a competitive advantage, allowing them to optimize bandwidth while offering data-intensive, real-time applications, such as streaming video.
- Innovate the Backhaul
The most innovative mobile backhaul networks combine IP, TDM, and ATM networks into a single Ethernet network. These converged backhaul networks can transport traffic that uses multi-layer protocols, so service providers need to test protocol interactions and determine how any problems on one network layer could effect the others.

MIMO Channel Emulation
Fourth-generation (4G) wireless relies on Multiple-Input Multiple-Output (MIMO) technology to deliver on the promises of higher data rates, greater coverage areas, and lower operational costs. However, testing base station and mobile devices that utilise MIMO technology is more complex and critical than ever. Successful testing requires a highly accurate emulated radio channel for testing base station receivers and mobile device receivers.
To reduce deployment problems and protect revenues, Matrium Technologies, the global provider of wireless performance testing, have integrated a turnkey 4x4 MIMO configuration into its renowned SR5500 Wireless Channel Emulator. By utilising our MIMO solutions you can maximise the potential of 4G and minimise the risks.
