Performance Analysis and Experiment of Data Transmission Rate of LEDs in Optical Camera Communication for Indoor Positioning System

Mobile Application for Visible Light Communication Systems: An Approach for Indoor Positioning

“…In Ref. [48], Nam et al proposed that the center distance of the two closest LEDs from 35 cm to 50 cm as shown in Figure 24 will achieve the highest transmission speed with distances from 200 cm to 300 cm. To achieve such results, Nam et al conducted In this test, the parallel LEDs in the LED cluster need to be designed with a suitable distance to achieve the highest transmission accuracy rate with a ceiling distance from 300 cm to 400 cm.…”

“…In Ref. [48], Nam et al proposed that the center distance of the two closest LEDs from 35 cm to 50 cm as shown in Figure 24 will achieve the highest transmission speed with distances from 200 cm to 300 cm. To achieve such results, Nam et al conducted an experiment in which Tx is a cluster of two LED downlights and Rx is a webcam connected to software programmed in the LabVIEW environment.…”

“…Therefore, determining a method to calculate N pixel/bit that is compatible across all smartphone ROM versions is also a challenge. In [48], Nam et al proposed a method to calculate N pixel/bit by measuring the coordinates of the starting point and ending point of RoI and counting the number of bright/dark stripes the RoI line passes through. From there will be the length of the RoI line and the number of stripes.…”

Facebook Advertisements’ Impact on Undergraduate Consumer’s Purchasing Intention in Sindh, Pakistan

“…Consumers have the intention to share information with them via social media (Sun et al, 2015). On the other side, the majority of new consumers hesitate to buy because of many issues in online buying, and this becomes a barrier to e-commerce growth (Nguyen et al, 2022). Hence, As a result, a greater understanding of purchase intention is critical for the company's business (Dachyar, Banjarnahor, 2017).…”

“…Preferences towards Facebook Advertisements: In Pakistan, 75 % are Facebook users in Pakistan (Gallup Pakistan, 2022). In addition to this, advertisers pay extra attention to Facebook due to its large user base and attractiveness among young people (Nguyen et al, 2022). Facebook offers a wide range of advertising; including promoting certain Facebook pages, events, and apps, sending visitors to specific websites, and users user-generated content (Imtiaz et al, 2021).…”
