The CTIA MIMO Expert Forum brought together technologists from ETS-Lindgren, Agilent Technologies, Spirent Communications and EB (Elektrobit) to discuss the challenges of OTA testing. The “Top Ten” questions received from attendees at last year’s CTIA MIMO Expert Forum are answered below.
This white paper summarizes the technology options for supporting voice and short message service (SMS) in LTE, including circuit switched fallback (CSFB), SMS over SGs, and voice over LTE (VoLTE). It includes background information on the standardization process, and the commercial implications for the different options. The white paper also addresses test and measurement requirements resulting from the support of voice and SMS in LTE.
Microlease has become the first test equipment specialist to offer the newly-released Anritsu MW8209A PIM Master as a rental option. The analyser covers the 900 MHz band and is designed to address the growing requirement for the measurement of PIM in E-GSM networks, including UMTS Band VIII and LTE Band 8.
AtlanTecRF claims that its new ALR series of Satellite Loop Test Translators (LTT) introduces, for the first time, the concept of synthesised Local Oscillator (LO) frequency control to provide the user with a compact, versatile and comprehensive approach to satellite communications equipment alignment and quality monitoring in both the Ka-band and Ku-bands.
Anritsu Corp. and Signalion GmbH conducted a successful IOT for the 3GPP LTE-Advanced ‘carrier aggregation’ feature with an IP downlink throughput of 300 Mbps. Both companies are leaders in providing test solutions for the 3GPP LTE radio technology and as a result of this IOT collaboration, the two companies will supply dependable test solutions for 3GPP LTE-Advanced.
The Centre for Wireless Communications (CWC), a project-funded research group operating in conjunction with the Department of Communications Engineering at the University of Oulu, Finland, is employing EB Propsim F8 radio channel emulator and EB MIMO OTA Application to provide wireless testing and research capabilities under the most realistic propagation conditions.
IFEN, working in partnership with WORK Microwave, announced an enhanced version of its NavX®-NCS Professional, a multi-frequency simulator, which is optimized for research and development of Global Navigation Satellite System (GNSS) safety and professional applications.
Test and measurement products from HAMEG Instruments are now directly available from Rohde & Schwarz almost anywhere in the world, which has prompted the decision to brand these products with a new logo that contains the names of both companies. This move is intended to further increase the brand awareness and growth of HAMEG Instruments and within the next three months, the dual logo will be introduced in nearly all regions.
Rohde & Schwarz is taking a completely new approach to measuring radiated spurious emissions on LTE devices, making it considerably easier for users to measure RSE in the presence of LTE carrier power. The solution is the R&S OSP open switch and control platform equipped with the new R&S OSP-B155 option.
Individuals who view calibration as a necessary evil are not taking into account the bigger picture. Calibration is essential to improving a company's bottom line, by minimizing risk to product defects and recalls, and enhancing a reputation for consistent quality.
