Smart Antenna technology and artificial intelligence (AI) have been central to developing modern wireless networks. The limitations of frequency bands and the performance requirements of networks demand innovative solutions where these technologies provide significant improvements—sometimes at the expense of traditional network design.
How Does Smart Antenna Technology Work?
Smart Antenna technology utilizes advanced algorithms that electronically adjust the antenna’s radiation pattern and polarization. These high-speed selection algorithms allow the system to choose the optimal radiation configuration from thousands of options within milliseconds. This technology significantly enhances the targeting of end devices compared to traditional antennas, leading to:
- Faster data transfer rates
- Broader coverage in challenging conditions
- Reduced interference
- Increased overall network capacity
Many base station radio signals are wasted because they radiate in all directions. With Smart Antenna solutions, the signal is directed where needed—not into a neighbor’s empty office. Although Smart Antenna technology makes WiFi access points slightly more expensive, it reduces the required access points while improving network performance and user experience.
WiFi Site Survey: An Obsolete Practice or a Necessity?
The site survey service has sparked debate for decades in the design of corporate WiFi networks. Some experts still consider it essential, but I have long questioned its necessity in a modern environment. Smart Antenna technology and AI can replace traditional coverage mapping with real-time, dynamic optimization.
TIP 1: Avoid Acquiring Too Many Access Points
Network salespeople are often tempted to recommend additional access points to enhance coverage and performance. In reality, intelligent radio network management software can automatically shut down some access points when they are not needed, reducing interference and improving network performance. Acquiring extra access points is unnecessary in an intelligent network, where a few reserve access points suffice. This alternative is also significantly more cost-effective than manual expert work.
TIP 2: Choose Intelligent Access Points and Radios
Modern WiFi networks leverage adaptive radio network management, which can use AI to optimize the network based on real-time situational awareness. The number of end devices, technology, location, and neighboring networks form a dynamic ecosystem. AI enables continuous Site Surveys, meaning traditional, one-time design services and manual channel management are no longer sufficient. Combining Smart Antenna technology and AI makes creating an intelligent network that operates optimally under changing conditions possible.
Intelligent Acquisition: What Distinguishes WiFi Solutions?
Corporate WiFi access points and home-use solutions may appear similar in product descriptions, but their architectures and technical solutions differ significantly. These differences directly affect network performance, scalability, and user experience. Therefore, choosing a solution that supports intelligent features, such as Smart Antenna technology and AI-based optimization, is crucial to maximize network performance.
