Anritsu Corporation (June 9, 2006 in Japan) announced that it has developed the RNC emulator MD8291A capable of testing 3G W-CDMA base stations and 3.5G HSDPA[*1] base stations.
The MD8391A is an emulator that works as an RNC (Radio Network Controller) [* See Tip] to connect NodeB[*2] to the core network part. By utilizing this new product, a base station test environment can be established without the use of expensive physical wireless network controllers or core networks. This enables the product to perform common operational and application tests not only through voice call trials, video telephony trials and IP packet transmission trials, but also with the digital mobile radio transmitter tester MS8609A and the vector signal generator MG3700A. Time to test the wireless performance.
By providing all the necessary tests in the production of W-CDMA or high-speed downlink packet access technology base stations, this product will help reduce production costs and increase work efficiency.
[Development background]
As the 3G mobile phone service continues to expand globally, W-CDMA base stations are configured to increase the number of available numbers. HSDPA, a high-speed data communication technology for W-CDMA systems, is also involved in the scope of deployment. With this in mind, base station manufacturers have also placed their work on producing high quality, low cost base stations. Prior to this, however, in order to test a Node B base station on a production line, it was necessary to use a physical RNC and a core network or correspondingly use an expensive simulator developed for research and development. Both methods require considerable equipment investment.
Anritsu has provided a variety of RF measurement solutions for base station development, production and maintenance from the digital mobile radio transmitter tester MS8609A to the vector signal generator MG3700A to the site host in the 3G base station market.
In order to expand the scope of our base station test solution, Anritsu has now developed the RNC emulator MD8391A, which mimics Iub[*3] signaling. Using this product only in conjunction with the MS8609A and MG3700A, the MD8391A eliminates the need to use expensive RNCs and core networks and can perform the required W-CDMA/HSDPA Node B base station tests at the production floor at very low cost. We now offer complete W-CDMA/HSDPA base station test support, including wireless and wired parts.
[product Overview]
MD8391A is an Iub emulator that enables it to perform W-CDMA/HSDPA Node B base station testing by mimicking the RNC between the Node B site and the core network. Since the MD8391A uses a plug-in module, the interface module for connecting the base station and optional modules can be selected according to the needs of the test. The Iub interface provides a widely used ATM (Asynchronous Transfer Mode) interface (transmission rate: 156 Mbps, 1.5 Mbps/2 Mbps, 6.3 Mbps, 25 Mbps) and a 10 Mbps/100 Mbps Ethernet interface that is expected to become mainstream in the future. The ATM interface is HSDPA compliant, which makes testing HSDPA Node B base stations possible. By using the optional module, you can not only perform packet transmission test, voice call test and ISDN video phone test but also check user data by performing MD8391A with digital mobile wireless transmitter tester MS8609A and vector signal generator MG3700A. The Node B base station transmits. Up to two interface modules can be used, which makes it possible to test two Node B base stations simultaneously.
[Main Features/Functions]
â–¡ Allow testing in an environment similar to the actual operation.
It is possible to establish a test environment comparable to a base station in operation by controlling the Node B base station from the Iub interface.
â–¡ covers all test clauses required during production
Voice call trials, video telephony trials, packet delivery trials, and bit error rate testing are possible through the use of interface modules and optional modules.
In addition, by using the MD8391A and the digital mobile wireless transmitter tester MS8609A and the vector signal generator MG3700A in combination, it is possible to perform the radio frequency characteristic test in accordance with the 3GPP TS25.141 standard [*4].
â–¡ Remote control function
Since the MD8391A has built-in remote control commands for automated line inspection, an automated inspection system can be built using an external PC controller in conjunction with other external devices.
â–¡ The ability to establish any protocol sequence Scenario.
By writing a Scenario [*5] in the widely used C language, it is possible to perform any desired signaling test. By further combining it with the optional software RNC emulation designer MX83907A, it is possible to build Secnarios using a GUI (Graphical User Interface) [*6] without the knowledge of C programming.
â–¡ small size and light weight
350 (W) x 132.5 (H) x 373 (L), less than 10 kg. Place it on a 19-inch shelf.
[Target market and application]
â–¡ Production, installation and maintenance of W-CDMA/HSDPA Node B base stations for 3G/3.5G network providers and operators.
