Summary
This study enhances IEEE 802.11be wireless local area network (WLAN) reliability for factory automation. WLAN LDPC and New Radio Polar Codes show the best performance in industrial environments.
Area of Science:
- Wireless Communications
- Industrial Networking
- Information Theory
Background:
- Factory automation demands high reliability and low latency wireless systems.
- Existing wireless local area network (WLAN) standards struggle with harsh industrial environments.
- IEEE 802.11be is a new standard being evaluated for factory automation (FA) due to its potential to address latency and reliability issues.
Purpose of the Study:
- To evaluate and compare different channel coding techniques for the IEEE 802.11be standard in factory automation scenarios.
- To identify coding methods that improve physical layer reliability under challenging industrial conditions.
- To assess the suitability of emerging and existing coding schemes for future industrial wireless networks.
Main Methods:
- Implementation of an IEEE 802.11be prototype.
- Testing of various channel coding techniques: WLAN Low-Density Parity-Check (LDPC), WLAN Convolutional Codes (CC), New Radio (NR) Polar Codes, and Long Term Evolution (LTE)-based Turbo Codes.
- Evaluation under Additive White Gaussian Noise (AWGN) and industrial channel models.
Main Results:
- WLAN LDPC codes demonstrated superior performance in factory automation use cases.
- New Radio Polar Codes also exhibited strong performance, making them suitable for industrial environments.
- Other tested codes, such as WLAN CC and LTE-based Turbo Codes, showed varying degrees of effectiveness under the tested conditions.
Conclusions:
- IEEE 802.11be, with appropriate channel coding, shows promise for reliable factory automation.
- WLAN LDPC and NR Polar Codes are the most effective solutions for enhancing physical layer reliability in industrial settings.
- Further research into optimizing these codes for specific FA requirements is recommended.

01:23Transmission Line Design Considerations
237
Aluminum has become the material of choice for overhead transmission lines, surpassing copper due to its abundance and cost-effectiveness. The most prevalent type is the aluminum conductor, steel-reinforced (ACSR), which combines aluminum strands around a steel core. Other variants include all-aluminum conductors (AAC), all-aluminum alloy conductors (AAAC), aluminum conductor alloy-reinforced (ACAR), and aluminum-clad steel conductors. Advanced designs, such as aluminum conductors with steel...

Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.

01:21Pilot and Numeric Relaying
158
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

The innovation of touch-tone telephony revolutionized the telecommunications industry by replacing the traditional rotary dial with a dual-tone multi-frequency (DTMF) signaling system. This system uses a matrix-style keypad with buttons arranged in four rows and three columns, creating 12 distinct signals each assigned to a pair of frequencies. Each button press results in a simultaneous generation of two sinusoidal tones – one from a low-frequency group (697 to 941 Hz) and one from a...

01:25Distribution Reliability and Automation
174
Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

01:24PI Controller: Design
580
Proportional Integral (PI) controllers are a fundamental component in modern control systems, widely used to enhance performance and mitigate steady-state errors. They are particularly effective in applications such as automatic brightness adjustment on smartphones, where they excel at mitigating steady-state errors for step-function inputs. Unlike PD controllers, which require time-varying errors to function optimally, PI controllers leverage their integral component to address residual...
