What Space Time Engineering does

Space Time Engineering (STE) is a privately held, self-funded modeling and simulation (M&S) software company founded in May 2007 and headquartered in Rolling Hills Estates, California, with a wholly owned Japanese subsidiary (株式会社スペースタイムエンジニアリング) established in April 2008 that serves as the primary commercial and engineering base. The company develops and sells the Scenargie simulation framework, which integrates Parallel Discrete Event Simulation (PDES), Multi-Agent Simulation (MAS), and Geographic Information System (GIS) technologies to evaluate end-to-end performance of large-scale, complex wireless communications and networking systems without model abstraction. The platform is extensible through modules for IEEE 802.11 (Wi-Fi), 3GPP LTE, ITS/V2X, multi-agent mobility, and ray-trace-based RF propagation (developed with Remcom), and is delivered with a Visual Lab GUI frontend. Beyond the core simulation product, STE has built a Smart disaster management product line (Smart Fire Department, Smart Disaster Response Headquarters, Smart Crisis Management, Smart Evacuee Reception, and Anshin Life community app) that leverages the same DTN-based patent shared with NICT (Patent No. 7427176) to provide communication continuity when infrastructure fails.

STE generates revenue through commercial perpetual and termed (annual) software licenses with mandatory annual maintenance, an academic license program, paid hands-on training seminars, consulting and engineering services (including IEEE 802.11/802.16 standardization support), and limited hardware sales of the Scenargie Comm Node WLAN experimental platform. Distribution is direct via the US headquarters and the Japanese subsidiary, with floating-license servers enabling concurrent usage; quote-based pricing is the norm and no public price list exists. The customer base is concentrated in Japanese and US R&D institutions, universities, and government agencies, including NICT, ATR, Panasonic System Networks R&D, Kochi City Fire Department, Tokushima Prefecture, and a roster of Japanese universities (Kobe, NAIST, Osaka, Hiroshima City, Niigata, Ritsumeikan, Kansai). The company holds ISO/IEC 27001:2013 certification (since 2019) and participates in multiple government R&D programs (MIC SCOPE/FORWARD, NICT commissioned research, Cabinet Office disaster prevention projects), with over 100 co-authored research papers and 18+ years of continuous platform development.

Direct peers

• ATDI: France-based vendor of radio network planning and spectrum management tools (ICS Telecom, HTZ Communications). ATDI competes directly with Scenargie and Synergy RF Planner for telecom operator and regulator RF planning budgets across EMEA and APAC.
• Remcom: US-based provider of electromagnetic and RF propagation simulation software (Wireless InSite, XFdtd). Remcom is both an integration partner (Fast Urban / High Fidelity Propagation Modules are co-developed) and a direct peer in RF propagation modeling serving overlapping telecom and defense customers.
• Forsk (Atoll): Forsk develops Atoll, a leading RF planning and radio network simulation platform widely deployed by mobile operators and equipment vendors. It overlaps with Scenargie in LTE/5G system-level simulation and with Synergy RF Planner in propagation analysis.
• EDX Wireless (SignalPro): EDX Wireless offers SignalPro, a wireless network design and simulation suite for LTE, 5G, and IoT. It targets similar telecom R&D and operator customers as Scenargie with comparable RF planning and system-level evaluation capabilities.
• RANPLAN: UK-based provider of indoor/outdoor wireless network planning tools (Ranplan Professional, iBuildNet). RANPLAN's focus on heterogeneous network and indoor RF planning makes it a direct comparator to Scenargie's urban propagation modules and ITS extension.

Broad incumbents

• ANSYS: ANSYS provides multiphysics simulation including HFSS for electromagnetic analysis and HFSS SBR+ for radio propagation. It overlaps with Scenargie's high-fidelity ray-tracing propagation module and is adopted across the same aerospace, defense, and telecom customers.
• MathWorks: MathWorks produces MATLAB and Simulink, which include Wireless Toolbox, 5G Toolbox, and communications system-level simulation blocksets. It is a broad incumbent whose simulation capabilities overlap Scenargie for academic and automotive R&D customers.
• Altair Engineering (Feko): Altair's Feko and WinProp products deliver electromagnetic and radio propagation simulation for automotive V2X, urban, and indoor scenarios. Comparable to Scenargie's HFPM/FUPM modules and High Fidelity Propagation offering.
• OPNET (Riverbed Technology): Riverbed acquired OPNET, whose network simulation/modeling tools historically served telecom and enterprise R&D. Although Riverbed now emphasizes application performance, OPNET remains a comparable networking-system simulation heritage for STE's customers evaluating alternatives.

Emerging players

• AITEMIN: EMERGING_PLAYER focused on RF propagation prediction and wireless network planning tools. AITEMIN competes in the same niche RF planner category as Synergy RF Planner, particularly in European and Latin American markets.
