The Importance of Propagation Models for Access Point Placement

Oct 13, 2025 by magicalceylontours.com 100 views

In today's digital age, the demand for reliable and fast internet connections is increasing, particularly in public facilities such as supermarkets. One way to meet this need is to provide WiFi services that not only facilitate customers but also support communication among workers. Through WiFi facilities, workers can report the latest information to the head office, as well as implement advanced technology such as RFID (Radio Frequency Identification) for operational efficiency.

The Importance of Propagation Models for Access Point Placement

To ensure optimal WiFi signals in the supermarket, it is crucial to determine the number and position of the access point properly. The Multi-Wall Cost-231 Empirical Propagation Model is used to calculate signal losses that occur when the signal passes through various barriers in the building. This model considers factors such as the distance between shelves and materials used in construction, which can affect signal strength.

In the analysis conducted, the average distance between shelves in the supermarket was varied into several options: 0.75 meters, 1.25 meters, 1.75 meters, 2 meters, and 2.3 meters. The measurement results show that the maximum signal loss for each variation of the distance is as follows:

Distance of 0.75 meters: 74,95193 dB at a distance of 11,6251 m
Distance of 1.25 meters: 78,99955 dB at a distance of 12,526 m
Distance of 1.75 meters: 78,16135 dB at a distance of 16,8216 m
2 meters distance: 78,37394 dB at a distance of 17,2384 m
Distance of 2.3 meters: 78,99963 dB at a distance of 18,527 m

Impact of Distance Variations and Barrier Material on Signal Losses

The results of the analysis show that the variation of distance between shelves, as well as barrier material, has a significant impact on the losses experienced by signals. The farther the distance between the shelves, the greater the signal losses that occur. This is very important in the planning and design of WiFi networks in supermarkets, where the effectiveness of internet communication and accessibility must be a top priority.

For supermarkets with a size of 125 x 81 square meters and the average distance between shelves of 2.3 meters, the analysis shows that it takes around 13 access points to ensure that the entire area is covered by an adequate WiFi signal. The placement of this access point must be done carefully, to avoid the dead zone where the signal cannot reach the user.

The Role of Cost-231 Multi-Wall Empirical Propagation Models in Supermarket WiFi Planning

The application of the Cost-231 Multi-Wall empirical propagation model in WiFi network planning in the supermarket provides important insights to ensure stable and efficient connections. Taking into account the distance between shelves and existing materials, supermarkets can determine the number and position of the right access point. This not only enhances customer experience but also supports better internal operations, including the application of modern technology such as RFID.
