• Power consumption
• Security

To make an informed decision, it's important to have a well-defined list of criteria. These criteria will help you systematically evaluate each wireless standard and determine which aligns best with your project's goals.

 

Proposed Criteria For Wireless Standards

When evaluating wireless standards for smart building systems, a comprehensive set of criteria must be used to ensure the chosen protocol meets the specific needs and requirements of the building's infrastructure and applications.

Here are the proposed criteria inspired by EnOcean's framework:

• Suitability of the frequency band (KO Criterion)  - Assess whether the frequency band is appropriate for the building's environment and applications. The frequency band must support reliable communication within the building's structure and layout, avoiding interference with other wireless systems. This is a knockout criterion, meaning the standard should be eliminated from consideration if the frequency band is not suitable. 

• Manufacturer dependence - Evaluate the extent of reliance on specific manufacturers for components and support. Multiple manufacturers should ideally support a wireless standard to ensure a competitive market, availability of parts, and long-term support. High dependence on a single manufacturer can lead to issues with compatibility, supply chain disruptions, and higher costs.

• Infrastructure - Consider the infrastructure requirements for implementing the wireless standard. This includes the need for gateways, repeaters, and other network components. A standard with minimal infrastructure requirements can reduce complexity and installation costs while providing deployment flexibility.

• Integrability - Examine the ease of integrating the wireless standard with existing building systems. The chosen standard should support seamless integration with current and future systems, ensuring interoperability and reducing the need for extensive modifications or custom solutions.

• Market Availability - Check the availability of compatible devices and components in the market. A widely adopted standard with a broad range of available products ensures that components are readily accessible and competitively priced. This availability indicates industry support and the likelihood of ongoing development and innovation.

• Measuring & Testing - Assess the tools and methods available for measuring and testing the wireless standard. Effective measurement and testing capabilities are essential for ensuring the system's performance, diagnosing issues, and maintaining the network. The availability of user-friendly tools and comprehensive documentation is a significant advantage.

• Power Supply - Evaluate the power supply options, including self-powered, battery-powered, and mains-powered devices. The choice of power supply impacts the system's maintenance requirements, operational costs, and environmental footprint. Self-powered or energy-harvesting devices, such as those using EnOcean technology, offer significant benefits in reducing maintenance and improving sustainability.

• Data encryption - Consider the level of data encryption and security offered by the wireless standard. Robust encryption and security protocols are essential to protect sensitive data and ensure the integrity of the smart building system. Evaluate the standard's support for high-level data security measures to safeguard against potential threats.

• Overall assessment - Provide a comprehensive evaluation of the wireless standard based on the above criteria. This overall assessment should weigh each standard's strengths and weaknesses, considering the project's specific needs. By systematically evaluating these criteria, building managers and engineers can make informed decisions, leading to a more efficient, secure, and scalable implementation of smart building technologies.
