Scientist in Optical Wireless Communication

Job TitleScientist in Optical Wireless Communication

Job Description

Your challenge

LED lighting has many advantages over conventional lighting, not only in terms of energy efficiency, life time, fine grain controllability of the light but also because the light output of LEDs can be modulated at high speed. Hence, light from LEDs can carry and exchange information. Philips Lighting successfully applies this in solutions for indoor positioning, location-based services and personal control of the light settings in offices. Moreover, we see various universities and companies offering Optical Wireless Communication (OWC) systems that use illumination LEDS to communicate data at bits rates in the same order of magnitude as Wi-Fi. Philips Lighting is looking for experts with expertise in wireless connectivity (with a sound foundation in communication theory and experience in medium access mechanisms) and with a strong interest to join us in creating innovative communication solutions.

OWC allows the use of ato-cells, thus to provide connectivity coverage in very well defined, small areas, thereby allowing a very dense reuse of the available bandwidth. This property makes OWC well suited for connecting for instance "Internet of Things" (IoT) devices or to deliver dedicated in-building services. To fully exploit the advantages of the optical wireless communication channel we need medium access (MAC) and network protocols which take the peculiarities of the physical light channel and the particular traffic patterns into account. We see opportunities in partially adopting existing radio protocols.

As a scientist you will be responsible for creating a competitive advantage in communication with light by creating networking solutions that enable novel applications and services, and fully exploit the properties the light communication channel.

OWC is one of many aspects Philips Lighting is exploring in the context of the IoT; deploying various connectivity technologies to connect light points, sensors and controls into novel lighting systems will enable advanced lighting applications as e.g. energy-saving controls as well as data-enabled services with lighting and non-lighting functionality.

Your responsibilities

As a Scientist in Communication networks you will create technical solutions in the field of:

  • Architecture specification for (optically) connected lighting components and systems
  • Embedded software implementations for connected, intelligent lighting components
  • Implementation of connectivity solutions for connected lighting, at components and systems level
  • Standardization of connectivity protocols and IoT technologies
  • Creation of IPR in the described field
  • Create and expand a network internally and externally to Philips in the connected lighting system context, in order to support the increasing business emphasis on open innovation and business partnering
  • Support the business in tackling challenges in new business models, e.g. in services, taking technical as well as economic innovation challenges into account
  • Your initial focus areas will be on the following topics:
  • Multiple access of multiple users connected to multiple light access points,
  • Optical channel reuse, networking aspects of Multiple Input Multiple Output
  • Seamless handovers
  • Quality of Service for diverse traffic streams

Your team

You will cooperate with your colleagues in the "IoT Systems" research group as well as with the connected systems community in Research, Development, Design and the business units, in standardization communities and with pilots and open innovation projects that may develop technologies and business concepts suitable for the strategic direction of Philips Lighting. You will be located in Eindhoven, High Tech Campus (The Netherlands).

Our offer

We welcome you to a challenging, innovative environment with great opportunities for you to explore.

Our benefits are very competitive and designed around your preferences:

  • Depending on experience, a market conform salary
  • 25 Days of leave and the possibility to purchase up to 20 extra days off annually
  • A variable bonus based on both Philips results and personal performance
  • Extensive set of tools to drive your career, such as a personal development budget, free training and coaching
  • Solid company pension scheme and attractive collective health insurance package
  • Opportunity to buy Philips shares and products with discount
  • Healthy work-life balance

We are looking for

Candidates who share our passion to improve people's live. To be successful in this role, you should be/have:

  • Master with 5+ years of experience or PhD, preferably in networking for wireless communication
  • Solid knowledge about media access and networking protocols used in optical or radio communication and understanding their limitations
  • Ability to think out of the box and to combine legacy solutions with innovative new concepts
  • Ability to consolidate ideas into transferable descriptions
  • Experience with Simulation tools, performance analysis and validation of protocols
  • Understanding of the physical optical wireless channel, and how this influences the network performance and how channel properties can be exploited at network level.
  • Willing to explore adjacent technical areas and work in a team with experts in adjacent areas.
  • Eager to work in a leading, world class innovative environment, and to apply unique technical strengths into innovative propositions in the market.

Recruitment process

If you're interested in this opportunity to join us, please upload your resume and motivation letter through the Philips career site by using vacancy number 204749. As we have no closing date set we urge you to apply as soon as possible!

The interviews will take place in Eindhoven, the Netherlands.
