EB Wireless Environment Solution
The Real World Radio Environment in Your Laboratory
Modern wireless systems are highly complex with different technologies such as GSM, WCDMA, TD-SCDMA, 3GPP LTE, 3.9G and WiMAX. The systems complexity is constantly growing in terms of different upcoming wireless technologies.
Understanding the radio channel behaviour is a key success factor in achieving the optimal performance in wireless networks and devices.
Testing of Wireless Systems is Challenging
The development of present and future wireless systems and communications imposes heavy requirements on testing.
The traditional wireless systems field testing is labour intensive, time consuming and expensive. In addition, test results are typically non-repeatable as interference and uncertainties often affect the results.
EB Brings the Real World Radio Environment into Your Lab
EB Wireless Environment Solution enables you to emulate the wireless environment in laboratory conditions. Reliable and repeatable virtual test runs in close-to-reality and controlled conditions can be executed fast.
EB Wireless Environment Solution will complement your existing radio network test tools and boost their utilization.
Who is it for?
EB Wireless Environment Solution will offer remarkable advantages especially to:
- 1. Network manufacturers
2. Network operators
3. Terminal and chipset manufacturers
Solution Overview
EB Wireless Environment Solution emulates the real wireless environment in laboratory conditions.
The data collected from real environment is used to emulate wireless environment in a laboratory. Testing, verifying and validation of wireless networks, devices, chipsets and applications is much more efficient compared to traditional methods. The radio environment is close to reality since all the phenomena that are simultaneously present in real radio networks are emulated: fast fading, signal level variations, the Doppler effect and interferences.
EB Wireless Environment Solution will complement (not replace) your existing test tools like system laboratory, network scanners and drive test tools. The solution will boost the utilization of your R&D and field measurement resources.
EB Wireless Environment Solution in 3 Easy Steps:
1. Measure Characterization of the radio environment to be emulated
2. Model and emulate
- Data analysis
- Drive route and creation of its characteristics
- Visualization of results
3. Verify
Repeatable emulation of the wireless environment at laboratory conditions

Technical Solution
Wireless system testing is traditionally conducted in non-repeatable radio environment in field conditions.
EB Wireless Environment Solution emulates the real wireless environment in laboratory conditions:
- The real radio environment is first measured in the field
- The radio environment is then emulated in laboratory conditions.
In a laboratory the user is able to control the network conditions all the time. This enables traceable, repeatable and accurate testing, verification and validation of wireless networks, devices, chipsets and applications.
The EB Wireless Environment Solution facilitates testing of intra-cell, intra-system and inter-system handovers. For example, handovers from one antenna sector to another and from one communication system to another.
The solution uses EB Propsim C8 to emulate all the phenomena that are simultaneously present in real radio networks: fast fading, signal level variations, the Doppler effect and interferences.
Full duplex radio channel links can be emulated. In addition, each up- and downlink channel can have unique multipath fading profiles with interference, fast fading and shadowing.
The solution enables reliable testing and benchmarking of wireless devices. Tests are fully repeatable and benchmarking results comparable.
The performance of wireless networks, devices, chipsets and applications can be optimized to ensure high quality of service and quality of experience.
