Given the increased demand for 5G connectivity in IoT, it’s easy to assume that 5G is the best solution for any high-speed application (digital signage being the obvious example). In fact, not all digital displays demand a 5G connection. In many cases, 4G is not just adequate, but preferred. More on that in a minute.
5G: The Pros
Today, many digital media providers choose 5G as their preferred solution, largely for the reasons listed below.
High Speeds – 5G is ideal for high-definition streaming, interactive content, and real-time updates. With its killer speeds, 5G makes buffering a thing of the past.
Wide Bandwidth – 5G also connects to multiple devices and supports high-data usage, particularly in high-density areas like urban centers or retail malls.
Low Latency – Once again, a 5G solution is perfect for touchscreens, dynamic ads, and other interactive displays that demand instant response times.
Improved Mobility – With 5G, digital displays can connect reliably on the go, at pop-up sites, and other temporary events.
Future Ready – Increasingly, 5G is a must when delivering more personalized content via artificial intelligence (AI) and augmented reality (AR).
5G: The Cons
It’s also obvious that 5G devices can’t function in areas with no 5G coverage (unless cellular devices are also 4G backward compatible and can latch on to a 4G signal in the area). The other alternative for no 5G is using wired connectivity for digital displays. However, this method not only increases installation costs, it also reduces deployment flexibility.
Here are a few other downsides to 5G:
Deployment Complexity – 5G deployments require considerable technical skill, more than for wired or Wi-Fi connections. Integrating a 5G solution with current systems can also be difficult.
Line-of-Sight Challenges – 5G is fast, but it also has a limited range that demands a clear line of sight / few physical barriers. Even climate and weather issues can impact a 5G signal for outdoor installations.
Data Insecurity – Digital media displays connected to 5G require high-level encryption and VPNs at minimum to avoid security vulnerabilities.
Power Consumption – Digital agencies using 5G devices can expect a high energy requirement. In particular, solar- or battery-powered signage may need to be monitored for power consumption.
High Costs – Both 5G equipment and data plans are more expensive than 4G. Routers are more sophisticated, generally including more bells and whistles – and data plans for 5G may range between $50 – $500 depending on the device and data limits. Fixed wireless access can also be pricey (anywhere from $100 to $500 monthly), depending on location. Agencies can expect to pay a premium for high-def streaming and added management services, as well.
In general for areas without 5G, businesses can compress files to save data usage, batch all content updates, and invest in dual-SIM technology or other failback options to protect network connectivity. If these tactics aren’t enough, consider 4G LTE.
