Facility managers, IT personnel, and those in charge of integrated security are the primary personnel responsible for making decisions when it comes to wired or wireless access control systems. There are multiple factors to consider, including reliability, operational cost, and real-world performance. This blog presents a comparison of wireless (cellular) vs. wired access control to help guide your decision-making process.
Wireless or Wired? How to Choose the Right Network for Your CellGate System
Today’s highly integrated IT ecosystems require a robust network to manage and maintain a diverse network of access control systems, which impact everything from building access and security to climate control and energy efficiency. Common threats to today’s infrastructure connectivity include insecure cabling or termination points, weak signal strength, interference, and even network reliability.
When it comes to choosing wired vs. cellular connectivity for your CellGate system, which is best? While both allow you to connect your access control devices to the internet, they differ in how their infrastructure delivers that connection. Your decision will depend on your specific use case, your current network ecosystem, and how you prioritize various factors such as speed, reliability, security, and cost.
Another key consideration that will influence the decision to choose wireless vs. wired is the existing infrastructure of the building itself. Factors such as the building’s composition and materials can weaken or even block cellular signals, which may require the addition of cellular boosters. Conversely, many older buildings have aging infrastructure, with outdated cabling incapable of supporting high-speed connectivity. However if the cabling already exists in close proximity to entry points, doors, and gates, you may find a wired solution optimal.
Here’s a quick snapshot of both your connection options:
- Wired – includes hard-wired physical cabling to deliver internet connectivity to buildings and devices. This cabling can be CAT-specific, fiber optic, or coaxial in nature, which offers both reliability and consistency in bandwidth speed, lower latency, and is less prone to interference.
- Cellular – much like the architecture of CellGate’s proprietary TrueCloud Connect, cellular data is transmitted through a series of mobile towers, which then route traffic to the internet through the carrier’s network. Each device in a cellular network maintains its own connection, requiring no setup or local infrastructure to support it.
Fundamentals of Cellular (Wireless) Networks
TrueCloud Connect is the backbone of Cell-Gate’s system architecture, capable of managing all data and communications between desktops, smartphones, and other devices – all through a single web-based interface. Cellular transmissions come standard with built-in encryption, offering users wide coverage areas that require no setup or local infrastructure to operate. The primary pitfalls with cellular-based networks can be the possibility of poor signal visibility, and variable costs based on monthly data plans and roaming charges.
Comparing Network Reliability
When it comes to network reliability, there are key strengths and tradeoffs to consider that impact network infrastructure setup, security, availability, and cost. Uptime expectations, the percentage of time that service is expected to be operational and available, and the impact on security are also important variables to consider.
The Federal Communications Commission (FCC) has oversight over broadband (which includes both wireless and wired internet) in the U.S. and classifies this service as being a public utility. In 2024, the commission issued an order that seeks to restore net neutrality which would establish policies that ensure equal internet reliability for all, encourage transparent reporting, and heighten network security. These policies aim to ensure that the distribution and speed of online networks are consistent and equal across the digital landscape.
Bandwidth Needs for Video Intercom Systems
Don’t know which type of video gate access control system is right for you? The choice between a wired and cellular network depends on your specific bandwidth needs, which are influenced by your property layout and the nature of your business.
A wireless CellGate system is often the ideal choice when there are no existing landlines at the gate, or if the cost and disruption of laying new wiring would be prohibitive. For example, if the property’s landline connection is far from the gate, or if the property is large and remote, a wireless system offers a much more flexible and cost-effective solution. In contrast, a wired system might be the optimal choice for a new construction project where wiring can be installed easily, or in an environment where a wiring infrastructure already exists.
The great news is that you don’t have to figure this all out on your own. CellGate’s expert team is ready to help you determine your specific bandwidth needs and recommend the optimal setup for your business. If wireless is the best choice, we have tools to help determine which cellular network works best at your location. CellGate partners with two cellular carriers – AT&T and Verizon – so we can implement your wireless system with the carrier offering the best cellular signal strength at your location, for best operational performance.
Whether your property is best served by a high-speed wired connection or a robust cellular system, our team can help ensure your system has the bandwidth to handle all your cameras and access points, providing the seamless security and performance your business deserves.
What about Wi-Fi for Access Control Systems?
Popular for both homes and businesses, WiFi data is routed via radio waves to nearby devices connected to a centralized router. It’s a wireless solution where many users can access multiple devices using one shared connection.
Unfortunately, Wi-Fi is susceptible to vulnerabilities that can compromise the reliability of an access control system. Wi-Fi performance can be affected by physical obstacles like thick walls or metal structures, as well as by interference from other Wi-Fi networks and electronic devices. These signal issues can lead to dropped connections or slow response times, which are unacceptable for a system that needs to operate flawlessly at all times. Furthermore, Wi-Fi is dependent on a local internet connection, meaning a power outage or ISP service disruption would render the system useless for remote management and monitoring.
From a security standpoint, connecting an access control system to a local Wi-Fi network introduces potential points of vulnerability. A compromised Wi-Fi network could give an unauthorized person a backdoor to the access control system, allowing them to bypass security protocols. Moreover, devices that operate on Wi-Fi are often susceptible to signal jamming, where a perpetrator uses a cheap, easily-accessible device to intentionally block the wireless signal, effectively disabling the system’s ability to communicate. Because of these inherent risks, security and access control companies often prefer solutions that operate independently of local Wi-Fi networks, such as those that use cellular communication or hard-wired ethernet connections, to ensure a higher level of reliability and security.
