JSpectrum is the only Location Based Services (LBS) company to provide mobile network operators with a complete suite of location enablers. Our comprehensive one-stop offering spans our proprietary network probes to middleware with API, LBA applications through to smartphone app libraries.

JSpectrum’s commercially proven NetWhere ™ is the only LBS platform which support real-time data decoding and high-velocity stream processing for event trigger with zero latency.  Additionally, we’re able to support state-of-the-art massive location history data storage on Hadoop for machine learning, analytics, and insights.


From Location Based Advertising to profiling to context inference, JSpectrum enables network operators to deliver cutting-edge contextual information and services based on users’ previous and current location, at the exact time it matters most.  This is the power of Where and When.


JSpectrum passively harnesses the rich, but transient signaling data flowing into the network and transforms this data into new revenue streams.

More than ever, contextual interaction is changing how users interact and how they shop, play, travel, discover and learn.  JSpectrum's gives mobile operators the edge.

Our Journey
So Far

2001 -2005

During the late 90's two experienced and enterprising telecommunications engineers, Alfred Ng and Eric Yung predicted ‘location as a service' would become a powerful and essential requirement for mobility. Mobile  networks generated rich, untapped data and big data platforms could help create new revenue streams by using signalling data in clever ways.


The pair successfully attracted funding from Hong Kong SAR Government's Innovation & Technology Fund (ITF) and in 2001 JSpectrum was created.  During the first phase of our history, we achieved the following milestones

  • Developed  Network Measurement Reports (NMR) based positioning algorithms using neural network. 

  • Developed a middleware using MLP3.1

  • Developed the first NetProbe (E1) for A-interface monitoring

  • First commercial Trial of Location Trigger Ad Campaign with CSL

  • Conducted a series of Pilot Trial of Passive LBS With SmarTone

  • Developed first SS7 MAP-based Location Polling

  • Won a tender from DTAC (Thailand) for a Location Based Hotspot SMS System



  • Received Order from SingTel for a  Pilot Location Based Ad System

  • Received Order from HKT for WiFi Location System

  • Launched NetProbe for IuCS and IuPS

  • Delivered MLP 3.2, NetProbe (SIGTRAN) HA & OSS

  • Won a multi-million dollar Tender for a Network Wide LBS System from SingTel

  • Entered a 3-year Revenue Sharing Agreement with SmarTone for LBS Advertising.  JSpectrum contributed software and support service.
