Log-periodic antenna covers a big band
The HL033 is a linearly polarised log-periodic antenna suitable for general transmission and reception applications in the frequency range from 80MHz to 2 GHz.
Radiocommunications tester takes HSDPA onboard
The CMU200 is the world's first and only radiocommunications tester with HSDPA functionalities already implemented.
The GSM network scanner can thus automatically locate interference sources in the event of cochannel or adjacent-channel interference.
HSDPA will be put into operation in many networks this year and allows downloads with datarates in the range of several megabits per second per user.
Network operators must ensure complete availability of services by proper network planning, and they must also decide which parts of the network should first be upgraded with HSDPA.
Equipped with the R and S Romes software, coverage measurement systems from Rohde and Schwarz provide valuable support in setting up HSDPA networks and optimising radio networks: an end-to-end application can be set up and evaluated during a test drive.
The measurements supply information about the actual HSDPA configuration, the availability and parameterisation of HSDPA services at different locations within the network, the signalling and the datarates achieved at different levels.
When it comes to measurement data acquisition for optimising WCDMA networks, the R and S TSMU has already set standards as a PN scanner.
Equipped with the new R and S TSMU-K13 GSM network scanner option, the R and S TSMU can now also analyse receive conditions in GSM networks.
To do so, the TSMU identifies the basestations in the network, measures their power and decodes the sys type information of the individual channels, eg CI/LAC/MNC/MCC.
Basestations cause interference in GSM networks when transmitting on the same or adjacent channels.
Equipped with a GSM network scanner, the TSMU can automatically detect, analyse and display this cochannel and adjacent-channel interference during a test drive.
By matching data with the basestation list, the interfering basestation is clearly identified.
The Romes measurement software includes the application for the GSM network scanner.
In addition, Romes features an automatic neighborhood and handover analyser, allowing network operators to check handovers within a 3G network and between 2G and 3G networks online during the measurement.
The analyser automatically compares the measurement results from a UMTS PN scanner, a GSM network scanner and a test mobile phone with the GSM BTS list and the UMTS Node B list.
A specially set algorithm tests the system to determine if potential interference is present or if adjacent cells are missing.
This convenient solution makes further analysis superfluous.
Combined with the Romes software, the TSMU radio network analyser provides a robust compact solution, consisting of a GSM network scanner (all GSM bands), a UMTS PN scanner (bands I to VI) for multiband measurements in up to 12 bands simultaneously plus CW measurement capabilities (80MHz to 3GHz).
The R and S TSMU can thus determine all the data of WCDMA and GSM mobile radio networks in all bands.
The new functions for the R and S TSMU base unit and the R and S Romes measurement software are available now from Rohde and Schwarz. Request a free brochure from Rohde and Schwarz ...
