3GSM World Congress Sees Highest Attendance
A new venue and a new city resulted in new record figures for the 3GSM World Congress when the event made the Fira de Barcelona conference and exhibition centre its new home. The four day event—13 February to 16 February—attracted a total audited attendance of 50,000 visitors (including visitors, delegates, participants and staff) to a site which provided double the floor space than in Cannes in 2005, accommodating a total of 962 companies, a 40 per cent increase from last year.
Visitors to what is claimed to be 'the biggest mobile show on Earth' may not have been readily conversant with the local Catalan and Castilian languages but communication in the common language of technological innovation was not a problem as the global mobile industry convened to network, exchange ideas and do business. In today's environment of fast technology change and increasing end-user expectations, 2006 promises to be a decisive year for new multimedia services and growing markets. A challenge that companies exhibiting at 3GSM World Congress seemed more than happy to embrace and meet head on, targeting the event to make numerous product innovations.
Particularly active in the microwave and RF arena were the test and measurement, semiconductor and chipset manufacturers. Read on for a selection of the major new product announcements from some of the leaders in our industry.
A key announcement was the launch of an Adaptive Multi-Rate (AMR) option for the 6113 base station tester to complement the company's existing GSM and GPRS/EDGE test capability. The AMR option extends the tester's coverage to enable testing of AMR-specific elements of the base station, in particular those parts that include AMR codecs in the signal path. Its A-bis control and decode capability allows both the transmitter and receiver paths to be fully tested. Unique receiver tests include bit error rate and frame erasure rate. Significantly, the AMR option also includes a 'live' mode that allows testing to be carried out without taking the base station out of service. Two key additional features of the 6113 AMR option include a rate adaptation test and a combined traffic/signalling channel BER test. The rate-adaptation test is not only used for checking that the base station is correctly measuring the carrier to interference ratio (C/I) but also as a tool for optimising the thresholds and hysterisis settings used to trigger rate-adaptation.
Other key announcements include: the significant extension to the capability of the 6103 AIME/CT GSM, GPRS, EGPRS mobile terminal protocol test system to include the first Dual Transfer Mode (DTM) test cases, a comprehensive suite of Downlink Advanced Receiver Performance (DARP) test cases, including three that are unique to Aeroflex and the complete suite of 3GPP Release 4 and EGPRS test cases as defined by the Global Certification Forum and PTCRB; the launch of a handset trace capability for the SystemAT laboratory-based test system, which is used for regression testing new wireless network software and features prior to rollout and handset validation/interoperability testing as well as network load and capacity testing.
A wealth of new products and initiatives were announced that underline the company’s commitment to its customers in the wireless communications market. Of particular interest is the announcement that the N4010A Wireless Connectivity Test Set supports the Bluetooth Enhanced Data Rate (EDR) test mode and offers new audio generation and analysis capabilities for Bluetooth audio test. Developers, integrators and manufacturers now have a single test set for ensuring devices adhere to the Bluetooth Special Interest Group's (SIG's) version 1.2 and 2.0 standards. Also, to ensure adherence to the new standard, the N4010A now enables loopback testing of EDR transmitters and receivers. Six of the eight Bluetooth 2.0 EDR test cases are integrated into the test set and the remaining two can be made utilizing the N4010A and additional equipment.
Another significant introduction is the release of the GS-8800 RF, the first commercially available pre-conformance test system that supports High-Speed Downlink Packet Access (HSDPA) test cases (3GPP TS 34.121). The test system enables cellular-phone design engineers to perform early RF design verification to meet a wide range of development needs. In addition to HSDPA, it supports other cellular technologies, such as W-CDMA, GSM/GPRS, EGPRS, cdmaOne/CDMA2000 and 1xEV-DO. As a result, cellular designers can be confident that their test platform is confirmed and continuously updated for the suite of test cases for UMTS devices.
These are just two products to highlight but Agilent also announced: new initiatives for WiMAX design and deployment and exhibited an extensive WiMAX product portfolio; a new IP UMTS Terrestrial Radio Access Network (IP UTRAN) signalling analyzer; the first commercially available base station test system compliant with the latest Common Public Radio Interface (CPRI) standards: new lab application features for the 8960 Wireless Test Set that provide real-life network emulation for GSM/GPRS and W-CDMA/HSDPA; a new Wireless Quality of Service Management solution; and collaboration with Freescale Semiconductor to create a test solution that can be used to efficiently test chipset platforms to the standards set by the ZigBee Alliance.
ANALOG DEVICES INC.
The company demonstrated its first W-CDMA/EDGE (WEDGE) chipset. Based on the Blackfin® Processor and advanced analogue, mixed-signal, and RF technologies, the highly integrated SoftFone®-W chipset comprises the AD6902 (Monza) digital baseband processor, AD6856 Stratos-W analogue baseband/audio/power-management IC, and the AD6541/AD6547 Othello®-W radio. The chipset supports the features generally included in mid to high end feature phones without requiring an external co-processor. The AD6902 also includes programmable serial ports and a flexible audio subsystem, allowing handset designers to easily support additional features such as FM radio, mobile TV, voice over WiFi and other applications.
Further testament to the prolific output of the test and measurement manufacturers at the show, the company launched and showcased a variety of new products. An important announcement was that the successful MD8470A application tester now has the added functionality of UE-to-UE connectivity testing in one instrument. This 'network on the bench solution' allows the user to test the application connectivity of the UE without setting up a live call on the real network. The Couple-UE Network Simulator (CNS) software provides the necessary network simulation to realize voice call, video call and SMS/MMS exchange between two UE, including UEs from different operators.
Also, HSDPA testing capability has been added to the UMTS Master MT8220A analyzer, producing what is claimed to be the first truly portable handheld test instrument that can verify Node B transmitter performance. When equipped with this new HSDPA option, the tester can make all the measurements listed in the 3GPP specification for HSDPA base station performance testing. Field technicians and wireless engineers can quickly check base station performance using any of the three options—RF measurement, demodulation and Over the Air (OTA). All key RF measurements, including band spectrum, channel spectrum, spectral emission mask and ACLR, can now be made on HSDPA signals. All standard WCDMA demodulation measurements can also be made. And there was more as the company announced: the introduction of the MD8391A RNC Simulator, a compact, low price Node B test solution. Mounted on a 19 inch rack and weighing less than 10 kg, the tester is aimed at infrastructure vendors wishing to efficiently test the Node Bs; the MS8911A DVB-T/H tester, a battery operated handheld tester for DVB-T and DVB-H analysis and the only tester in the market that performs DVB-H measurements; a WCDMA/HSDPA Modulation Quality Measurements option for the MS2781A Signature™ High Performance Signal Analyzer; and a next generation 3G SGSN Load Generator Test Tool for the market leading MD1230B Ethernet/IP test platform.
This may have been a new name to some visitors but the products and personnel were familiar as the company was the result of the acquisition of Agilent Technologies Inc.'s Semiconductor Products Group at the end of 2005. They haven't wasted time in developing new products announcing two new film bulk acoustic resonator (FBAR) duplexers for handsets, PC data cards and other wireless products operating in the US PCS and UMTS frequency bands. Both duplexers are housed in the industry's smallest, ultra-thin packages featuring a height of 1.3 mm, with a 3.8 mm by 3.8 mm footprint. These dimensions are achieved through the company's Microcap bonded-wafer chip scale packaging and enable miniature RF modules with increased functionality to be embedded into other portable consumer appliances. The ACMD-7402 duplexer is optimized for the US PCS band 1850.5 to 1909.5 MHz transmit, 1930.5 to 1989.5 MHz receive and offers low TX insertion loss and excellent rejection that enhances sensitivity and dynamic range. Similarly, the ACMD-7601 is a high performance duplexer for UMTS Band I frequencies of 1920 to 1980 MHz transmit, 2110 to 2170 MHz receive—the frequency band is the most common version of the W-CDMA standard used in Europe and Asia. The device enhances sensitivity and dynamic range of UMTS receivers while extending handset battery life by minimizing the power amplifier's current drain. Also introduced was the ADCC-3000, a one-quarter inch optical format, 1.3 megapixel CMOS image sensor featuring the company's enhanced-performance (EP) pixel architecture and image-pipe processing technology. The sensor is one of the few 1.3 megapixel sensors that fits easily into the industry's smallest (8 mm x 8 mm x 5 mm) low profile camera modules.
Several innovations in mobile, sound entertainment and near field communication were showcased. These included the technology foundation to power Unlicensed Mobile Access (UMA) enabled phones using the Nexperia™ cellular system solution 6120 for UMA, which will be available shortly in the US market from a major operator. The company has collaborated with Kineto Wireless (also exhibiting at 3GSM) who provide the UMA-compliant handset software stack in the Nexperia cellular system solution. Requiring no additional setup by the consumer, UMA phones switch between cellular networks and WiFi hotspots, automatically detecting the fastest and most cost-effective network—reducing bills dramatically.
Additionally, the company displayed a single-package Bluetooth and FM Radio Solution (BGB260FM), which includes Bluetooth 2.0+EDR functionality with an FM stereo radio and is said to deliver the smallest PCB area solution on the market today. Aimed at the designers and manufacturers of mobile phones and headsets, the product provides a simple solution offering advanced, yet cost effective, functionality.
The simplicity of near field communication was demonstrated in an effective and novel way when Philips, together with Samsung and Telefonica Moviles, demonstrated an easy-to-use short-range wireless technology, by providing 200 attendees of the 3GSM World Congress with an NFC-enabled Samsung mobile phone which could be used for payment and access at the event. The company also showcased: the next generation TV-on-mobile solution (BGT215); and debuted a new NexperiaTM cellular system solution which gives advanced 3G voice and data coverage across both 2G and 3G networks by integrating support for UMTS, EDGE and Dual Transfer Mode (DTM).

ROHDE & SCHWARZ
3GSM is a major event for the company as witnessed by the plethora of new products launched and on display. The first to highlight is the expanded functionality of the R&S FSH3 handheld spectrum analyzer, with the introduction of the R&S FSH-K4 option, which adds the capability to perform code domain power measurements on 3GPP base stations. Test parameters include the overall power as well as the powers of the main code channels such as the Common Pilot Channel (CPICH), the Primary Common Control Physical Channel (P-CCPCH), the Primary Synchronization Channel (P-SCH) and the Secondary Synchronization Channel (S-SCH). The carrier frequency offset and the error vector magnitude are also measured and displayed. The option also includes an automatic level control function that allows users to quickly set the optimal reference level. For base stations equipped with two antennas, users can choose the antenna to which the spectrum analyzer is to synchronize (antenna diversity).
A second key announcement is that the company is now providing an option for Bluetooth V2.0 + EDR that complements the R&S CBT and the R&S CBT32. Fitted with the EDR option, these RF testers enable all measurements—with the exception of EDR C/I performance—to be performed without any external equipment or PCs. Significantly, with regard to EDR receiver tests, the option supports the loopback test mode in accordance with the specification. Like the basic versions, the R&S CBT and the R&S CBT32 with EDR option feature high measurement speed. Lab tasks can thus be handled quickly, reducing test times and costs in production.
Other key announcements include: an all-in-one measurement solution for WiMAX applications—by combining the R&S SMU200A vector signal generator and R&S FSQ signal analyzer, the company offers a future-proof measurement solution for WiMAX applications; the introduction of the R&S CMU-K72 HSDPA monitoring option to the R&S CMU300 universal radio communication tester. With this monitoring option it is possible to analyze the data flow on the high speed shared control channel (HS-SCCH), which enables the tester to simultaneously analyze four HS-SCCHs with up to 128 UEs altogether; similarly the HSDPA functionality of the R&S CMU200 mobile radio tester is enhanced when equipped with the R&S CMU-K64 software option. By using this new firmware upgrade, the tester is now able to set up a call to user equipment of classes up to 3.6 Mbit/s in the in signalling mode as well as the non-signalling mode.
It was a three-pronged attack as the company chose to make one major announcement on each of the first three days of the show. On Monday (13 February) and one year on from launching the Helios™ Mini the company unveiled Helios II, its next-generation EDGE radio. This highly integrated solution reduces the RF board space by condensing all required EDGE RF functionality into two compact devices: The SKY74137 RF transceiver is a highly integrated device for multi-band GSM, GPRS and EDGE applications. The receive path implements a direct down-conversion architecture, consisting of four integrated LNAs, a quadrature demodulator, selectable baseband filter bandwidths and low droop DC offset correction (DCOC) sequencer. The transceiver also implements company's polar loop transmit architecture, autonomously splitting the amplitude and phase within the device using traditional analogue in-phase and quadrature (I/Q) signals. Secondly, the SKY77331 PA module (PAM) is designed in a compact form factor with integrated coupler for quad-band GSM, GPRS and EDGE mobile handsets. Features include: high efficiency, integrated coupler, wideband envelope control path, input/output matching, and gold-plated lead-free contacts.
On the Tuesday (14 February) two new ultra-compact and high efficiency EDGE front-end modules (FEMs) for leading mobile handset suppliers were launched. The SKY77512 transmit FEM is designed in a compact form factor of 8 mm x 8 mm x 1.2 mm for quad-band mobile handsets supporting GMSK and linear enhanced data for EDGE modulation. The SKY77519 is a transmit and receive FEM designed in a very low profile compact form factor of 6 mm x 6 mm x 1.1 mm for quad-band WEDGE mobile handsets. It is said to be the industry's smallest module for open-polar EDGE. When combined with the company's FEMs for closed loop platforms, Skyworks supports all three EDGE architectures—closed loop, open loop and linear implementations.
Wednesday (15 February) saw the addition of a highly integrated transmit WCDMA FEM supporting HSDPA to the company's InteraTM portfolio. The SKY77427 is a fully matched, 22-pin surface mount module that enables customers global support with band I, II and V coverage, which are anticipated to be the dominant frequency bands for 3G handsets. By integrating its next-generation, innovative load insensitive power amplifier (LIPATM), a duplexer, power detector and filters into a single 5 mm x 8 mm package, the company's InteraTM FEMs allow mobile handset designers to simplify RF design and reduce board space.
Unveiled were products that realise the promise of a truly integrated WCDMA and EDGE RF front end. First is the release of two new smaller form factor WCDMA and EDGE wireless phone receive modules designed to better meet the signal processing needs in next-generation, multi-mode slim-line (cellular) handsets that use both WCDMA and EDGE (WEDGE) networks. The new modules (numbered 890057 and 890060) are tri-band and quad-band, respectively. The 890057 covers the WCDMA-2100 band, plus GSM 900/1800/1900 bands. The 890060 is ideal for phones requiring the WCDMA-2100 band, plus GSM 850/900/1800/1900 bands. The modules offer a combination of WCDMA linearity (signal precision) that meets 3GPP out-of-band blocking requirements and low transmission path insertion loss—all in a small size (5.4 mm x 4.0 mm) with a height profile of 1.1 mm.
Important too is the release of the company's latest quad-band transmit module, the TQM6M5001 that provides full GSM/EDGE capability. It enables the higher EDGE bandwidth services sought after by wireless phone users and its high level integration allows phone designers to move from the GPRS of GSM service to full EDGE, which affords data rates up to three times faster than GPRS. The new module measures 6mm x 6mm x 1.1 mm3. This breakthrough product is an all-in-one RF transmit module with full Gaussian minimum shift keying (GMSK) and EDGE linear functionality, combining a quad-band EDGE PA, a linear transmit/receive switch, plus PA and switch control along with electrostatic discharge protection.
Other new products featured include: three new highly integrated WCDMA modules that reduce the RF front end complexity of 3G phones. Each designed to provide key performance enhancements within a multi-band WCDMA handset: cellular (TQM616017), PCS (TQM666017) and IMT2100 (TQM676001); the p/n 890047, the company's latest fully optimized WCDMA/GSM quad-band switch module for the RF front end of 3G handsets; and the TQM7M5003 quad-band GSM/EDGE-polar power amplifier module, for use in GSM/EDGE wireless handsets and data cards in the GSM 850/900/1800/1900 bands.
News from the Show Floor
As well as announcing new products exhibitors also made the news.
The China Academy of Telecommunication Research (CATR) has selected a system from Rohde & Schwarz for certification in the field of radio resource management (RRM). The Protocol Testers R&S CRTU-M and R&S CRTU-S and the Spectrum Analyzer R&S FSU are being added to the Protocol Tester R&S CRTU-W, which has already been put into operation by CATR. Rohde & Schwarz thus provides the Chinese regulatory authority with a complete RRM system for which worldwide the most RRM test cases defined in specification 34.121 chapter 8 are validated.
The typical RRM test situation confronts the mobile phone with a change of the radio signal. The test subsequently determines how long the mobile phone takes to detect the better cell and to make the change. For RRM certification, CATR opened an invitation for tenders in summer 2005 and has now decided in favor of the system from Rohde & Schwarz.
In 2003, Rohde & Schwarz won a bid from MTNet, a CATR laboratory, and delivered the Test System R&S TS8950-W. The new cooperation with CATR—through its MTNet and CTTL labs—further strengthens Rohde & Schwarz's position on the Chinese mobile radio market.
The R&S TS8950 as well as the RRM system are suitable for certification in accordance with the Global Certification Forum (GCF) and the PCS Type Certification Review Board (PTCRB) and are available from Rohde & Schwarz.
