spirent Gss5700 Wi-Fi Positioning Access Point Simulator The new GSS5700 simulates Wi-Fi network elements to enable lab-based testing of the latest Wi-Fi positioning technology. The GSS5700 can work as a stand-alone test instrument, or in conjunction with Spirent’s market-leading GPS/GNSS and automated location test products. Wi-Fi positioning technology is becoming a “must have” element APPLICATIONS of location technology on consumer devices where a user’s Manufacturers: location is required quickly, accurately and to be available everywhere. While no single location technology meets this • Research & Development need, Wireless LAN (Wi-Fi) positioning, when used with other • Integration technologies (particularly GNSS and Cell-ID) in a hybrid solution, • Design verification can play a major role in delivering a quality LBS user experience. • Performance analysis Already the world leader in GPS and Multi-GNSS (e.g. GPS and • Benchmarking GLONASS) simulation and A-GNSS test solutions, Spirent has • broadened its test capabilities to include Wi-Fi positioning. Regression Test Spirent’s GSS5700 Wi-Fi Positioning Simulator is a first-of-its-kind Operators: test tool that enables repeatable and reliable device testing to be carried out in the lab, reducing the need for costly and time- • Pre-launch evaluation consuming field testing. • Software regression test • The GSS5700 enables simultaneous simulation of multiple Acceptance test Wi-Fi Access Points (APs), each of which can be configured and controlled independently. Advanced software features make it easy to create tests that replicate real-world scenarios, including advanced vehicle motion, adversarial situations and a user- definable AP database. The GSS5700 can also be combined with Spirent’s range of GPS and multi-GNSS Simulation Systems to test true hybrid location performance. The GSS5700 will also form an integral part of Spirent’s 8100 (UMTS) and C2K-ATS (CDMA) Location Technology solutions, providing full automation of mobile device test scenarios and performance metrics. BENEFITS • Reduce Time to Market – test device performance under controlled, repeatable conditions in the lab, reducing the need for time-consuming field testing • Improve Wi-Fi Positioning Performance – with a unique first- of-its-kind solution enabling testing under a wide range of conditions • Ensure Hybrid Location Performance – validate hybrid GPS, Multi-GNSS and Wi-Fi positioning performance including hand-off and error conditions SPIRENT GSS5700 Wi-Fi Positioning Access Point Simulator KEY FEATURES OPERATING MODES • Software suites provide powerful test definition tools and all The GSS5700 is able to simultaneously reproduce the relevant modeling relevant to simulated motion of device under test beacon signaling associated with multiple APs and offers three and channel power level modeling operating modes: • Emulation Mode Individual Wi-Fi access point characteristics, including location coordinates, MAC address, transmit ERP and The GSS5700 operates as a controllable instrument, where channel number, can be imported or defined via a remote fundamental characteristics can be defined for each AP signal user interface and stored as an ASCII database being received: MAC address, signal channel number and incident power level. Independent AP resources are available • Simulation of 12 APs in standard configuration. Expandable to enable emulation of all 14 possible 802.11 channels up to 24 in a single chassis and up to 48 APs with simultaneously. User interaction is via remote GUI, remote expansion chassis command API or the front-panel LCD screen. • Full interoperability with Spirent’s GSS6700 GPS/GLONASS/ Simulation Mode Galileo Simulation System and GSS6560 GPS Simulator plus The GSS5700 dynamically re-creates an operational environment, other simulators running SimGEN software simulating the device under test moving through a collection • Supports Wi-Fi TCP/IP data connection via one AP of static APs, with power level being a deterministic function of distance from the AP (path loss) and its transmit power. A • Integration with Spirent’s Location Technology solutions stochastic ‘fading’ model may also be overlayed on the power (LTS and PLTS) offers comprehensive, automated mobile profile. As in Emulated mode, the MAC address and channel device location performance testing (available H2 2011) number are user-defined but are contained in an AP database along with AP location and effective radiated power (ERP). APs are selected automatically and dynamically from those ’in- view’ based on highest incident power. Test cases are managed via SimGEN and run-time AP-specific data is displayed on the SimGEN controller and front-panel LCD. Replay Mode The GSS5700 operates similarly to Simulation mode but determines AP selection and received power level directly from a time-ordered script of AP visibility and characteristics that is either derived from field observations or created artificially. Replay mode can also remotely stimulate SimGEN GNSS simulations. User interaction is via remote GUI, remote command API or the front-panel LCD screen. The GSS5700’s user interface allows full interactive control (Emulation Mode). SPIRENT GSS5700 Wi-Fi Positioning Access Point Simulator The GSS5700’s user interface software allows modeling path losses against an array of AP locations. INTEGRATED DEVICE TESTING SOLUTION Full integration of the GSS5700 with Spirent’s Location TestDrive SimGEN GSS6560 or GSS6700 Technology Solution for UMTS, LTE and PLTS for CDMA Software Software GNSS Simulator testing will be offered in the 2nd half of 2011. This will enable complete, automated testing of mobile device performance that makes use of Wi-Fi positioning techniques.
