Wireless Technology in Access Control

Before jumping into how wireless is used in WiFi locks and wireless access control, let's take a look at the underlying technology: Wireless Fidelity commonly known as WiFi is a wireless technology for local area network LAN. This technology is governed by IEEE 802.11 standard for physical and media access control MAC.

WiFi technology commonly uses a 2.4 GHz wireless band reserved for industrial, scientific, and medical ISM applications; it can also use 900 MHz, 3.6 GHz, and 60 GHz bands.

The indoor WiFi network range varies between 66 ft to 230 ft based on the type of modulation, bandwidth, and other factors. The outdoor range is always a bit longer than the indoor ranges with the same network parameters due to lesser hindrances. A wide range of WiFi-enabled devices is available in the marketplace that includes cell phones, PCs, tablets, access control security systems, office equipment, home appliances, and others.

Wireless Access Control: Components

WiFi-based access system uses a combination of software and hardware resources. The main products commonly used in a WiFi-enabled security system include:

  • Electronic or wireless locks
  • Wireless readers
  • Wireless access point
  • Access control application
  • Fobs

These products communicate with each other through a wireless communication system.

How It Works

WiFi has become a very powerful technology in modern security and access control systems for a small as well as for a large building, organization, or institute. Internet of things (IoT) is one of the key models of future communication systems, which will integrate all equipment, devices, and home appliances commonly used in our day-to-day life. That integration will be accomplished through an IP-based internet system.

In a door access control system, the legacy locks of a building are replaced with wireless-enabled electronic locks. Those locks connect to a wireless access point or wireless router, which facilitates multiple wireless-enabled devices and locks to communicate with each other within specified criteria and conditions. The control and management of the entire door security access system are done through a software application, which provides an interface to configure the desired conditions and criteria for accessing the doors.

The replica of that software can also be installed on your mobile devices as a mobile app to control the system operations. Electronically programmed fobs can also be used for manual access to a particular area. This entire door access system can work in standalone, integrated, and offline modes through the proper configuration. While using the manual access method, an electronic fob is inserted into the wireless reader, which reads the data on that particular fob and establishes communication with the main application for access conditions and criteria. Based on those criteria, access to the wireless door locks is granted from the core application through wireless

Modern wireless door locks are able to handle multiple data input systems like thumb impressions, manual codes, images, and others through wireless door readers. Thus, they are much more intelligent than they were a few years back!

How do Wireless Locks Compare With Other Technologies?

Wireless locks are incredibly helpful in many use-cases and they often represent a very valid option. There are, however, some use cases where the wireless locks are not an ideal solution, we cover all these case scenarios on our page for smart locks.

Conclusion

Let's finally dive into the pros and cons of wireless locks compared to other technologies.

Pros

  • Cheaper than legacy and cloud-based access control systems
  • Good level of security
  • Can be installed without professionals most of the times and are very quick to install
  • A cool and modern touch for every office

Cons

  • They are not part of a bigger security eco-system
  • They are often not working in offline mode so this might represent a problem in the case of a blackout
  • They get obsolete quicker
