“…However, if the design team would have removed their preconceived notion of the product changing the way people communicate, they would have actually heard loud and clear that the sample group actually said they would never use the product—regardless of any modifications. 5 Organizations can help ensure that thorough discussions exist after a listening event by asking their teams to prepare thoughts before a meeting to avoid group-think and to further promote different perspectives on the material presented.…”

“…Figure 4 shows the measurement setup block diagram and Figure 5 its implementation, used to calibrate the model. The transmitter consists of an arbitrary wave generator (AWG), Siglent SDG6022X, a driver based on bias-T with a capacity of 22 µF and an inductance of 1 mH and low output impedance implemented with an OPA2677 [ 31 ], which are connected to the LED under test with a reflector C16902_ALISE-110-WW. At the receiver, the lens ACL25416U-A is used with the PDA10A2 amplified photodetector, whose output is connected to the Rohde&Schwarz RTM3004 oscilloscope (OSC).…”

LED lighting has become the standard solution for illumination purposes thanks to its energy efficiency. Nowadays, there is growing interest in the use of LEDs for data transmission to develop future-generation communication systems. The low cost and widespread deployment of phosphor-based white LEDs make them the best candidate for visible light communications (VLC), although they have a limited modulation bandwidth. This paper presents a simulation model of a VLC link based on phosphor-based white LEDs and a method to characterize the VLC setup used to perform the data transmission experiments. Specifically, the simulation model incorporates the frequency response of the LED, the noise levels coming from the lighting source and the acquisition electronics, and the attenuation due to both the propagation channel and the angular misalignment between the lighting source and the photoreceiver. In order to validate the suitability of the model for VLC, carrierless amplitude phase (CAP) and orthogonal frequency division multiplexing (OFDM) modulation signals were employed for data transmission, and simulations with the proposed model and measurements over the equivalent scenario show high agreement.
