Ascom Releases TEMS Investigation 10.0 with LTE Functionality

Ascom, a leading provider of in-vehicle network testing solutions, announced the release of TEMS Investigation 10.0 with new functionalities for Long-Term Evolution (LTE) and Time Division Synchronous Code Division Multiple Access (TD-SCDMA), and High-Speed Packet Access+ (HSPA+) technologies.
The release follows Ascom’s acquisition of TEMS mobile test business from Ericsson last month. TEMS is a worldwide leader in air interface testing, focusing on network optimization. Its product range complements and enhances Ascom’s Symphony line of benchmarking, drive test, and stationary test products.
TEMS Investigation is a tool for troubleshooting, verification, optimization, and maintenance of wireless networks. It includes data collection, real-time analysis and post-processing integrated into one tool and supports the daily optimization of wireless networks. TEMS Investigation provides a complete solution and eliminates the need for multiple tools, reducing costs and saving time and effort for operations staff.
Ascom’s TEMS Investigation 10.0 is provided with enhanced service testing for Code Division Multiple Access (CDMA), basic support for Integrated Digital Enhanced Network (iDEN) data collection, and voice and data service testing for TD-SCDMA. With new support for TD-SCDMA and iDEN, it can test all major technologies.
TEMS Investigation 10.0 also includes new scanner support for spectrum and enhanced power scanning. LTE signal scanning is improved so that scanned cells are now arrayed by channel number. Scanning capabilities are extended to cover the 900, 1800, 2100, AWS, and 2600 MHz bands.
Information elements allow performance analysis of HSPA when using the MIMO multi-antenna technology. Enhanced Audio Quality Measurement functionality now includes the Speech Quality Index in MOS scale for AMR WB codecs for both Global System for Mobile Communications (GSM) and WCDMA. Support for many new terminals has also been added.
“No matter what technology or what level of network maturity, all networks require testing and optimization,” says Rikard Lundqvist, TEMS managing director. “TEMS Investigation provides a proven mix of powerful data collection, testing, and analysis capabilities to help operators achieve better service performance for any network.”
