Future Lab - Securely connecting and operating testing environments

As remote instrument access and programmatic instrument control has become nearly effortless with standard ethernet/IP-based IT components, a secure integration of the customers network infrastructure is important. How can we master harmonizing available Ttest and measurement applications of various ages and operating systems while making sure that data and IT security are not compromised?

The LANCOM R&S Unified Firewall can act as a secure application gateway and is an important central part of the Rohde & Schwarz project "Future Lab".

Software defined WAN

When it comes to modifying and expanding your network infrastructure, the future-proof strategy is to switch to a SD-WAN solution. The complexity of static networks connecting dispersed locations used to be time-consuming and error-prone, but this can be significantly improved with an SD-WAN.

The advantage of an SD-WAN solution is that any available internet based wide area network (WAN) can be used to rapidly deploy digital applications and multi-service networks. We explain here why adopting SD-WAN is the best way to go.

WiFi 6E - New 6 GHZ WLAN complementing 5G Networks

With the numbers of end devices growing steadily and the increasing density of IoT devices, the load on the available Wi-Fi frequencies has made communication hardly possible without collisions. The new standard Wi-Fi 6E is the perfect completion for environments where 5G is not available or not possible.

5G and Wi-Fi 6 can be the ideal team. With 5G and Wi-Fi 6, mobile operators and Wi-Fi providers have new, faster standards. Ideally, there should be no need for either/or decisions. Optimized networks could well offer the advantages of both technologies.
