Aeroflex has announced it has added the ability to undertake live receiver testing and transmitter testing, including HSDPA, on its 6413A UMTS base station test system. The capability is suitable for the ongoing maintenance of UMTS base stations to ensure they perform to specification. It enables testing to be undertaken without any disruption to live traffic caused by taking the base station out of service.

The performance of the base station receiver is extremely important as it essentially defines quality of service in a cell. With the low operating power of mobile terminals, the performance of the receiver has to be exceptionally good at all times. A poorly performing base station receiver will result in an increased number of calls being dropped due to lower sensitivity and signal quality. Phones will be required to transmit at higher power, impacting battery life and potentially causing signal interference. It will also make it difficult for revenue generating higher data rate services to be used. A poorly performing base station will also significantly impact network planning as the number of calls a cell can handle will be restricted. Conversely, a 1dB improvement in base station receiver sensitivity, for example, can mean that 11 percent fewer base stations are required in network.

Complete base station control
The Aeroflex 6413A UMTS base station test system is designed specifically for the installation and commissioning, maintenance, fault-finding, performance verification and optimization of radio base stations. A single-box portable solution, it is able to take complete control of the base station via the Iub interface and perform all of the critical transmitter, receiver and functional tests without external control equipment or the need for detailed knowledge of the base station's operation and control.

The addition of a live receiver and transmitter testing capability to the Aeroflex 6413A UMTS base station test system compliments its existing Iub-controlled test mode, which facilitates the implementation of repeatable test scenarios in controlled environments based on the methods defined in the ETSI standard 3GPP TS25.141. The Aeroflex 6413A's user interface is intuitive to use. Based around an embedded PC and using touch-screen controls, all functions can be operated from the front panel. Measurement results can be viewed while tests are running or stored for later analysis. Tests can be run manually or automatically using pre-programmed test sequences.

Live testing
"The addition of live receiver and transmitter testing to the Aeroflex 6413A will considerably improve its appeal to network operators," said Ross Broadhurst, product marketing manager at Aeroflex Test Solutions. "Network operators will now be able to test base station performance and optimize their network quality of service without adversely interfering with the live traffic on the network."

The live receiver testing and transmitter testing is available for immediate delivery. The Aeroflex 6413A UMTS base station test system is highly configurable. For pricing for specific test applications, contact Aeroflex.
