| Printed schedules, paper signs in plastic holders, handwritten “Occupied” notes, many buildings still rely on paper signs that become outdated almost immediately. Room booking displays replace these temporary solutions with digital signage that updates automatically from your calendar or meeting room booking system. As employees continue to return to the office, making better use of available space has become a growing priority. According to the latest CBRE Global Workplace & Occupancy Insights, report, the average office occupancy rate worldwide increased from 38% in 2024 to 53%. As a result, real-time room availability and automated booking workflows are becoming the standard across businesses, educational institutions, and public sector organizations. |
What is a meeting room digital room sign?
Digital signage for meeting rooms are digital door signs installed outside meeting rooms. They display real-time information such as the room name, occupancy status, upcoming bookings and, depending on the environment, schedules or timetables. The information is automatically synchronized with a calendar or room booking system, eliminating the need to manually update paper signs.
Depending on the manufacturer, these solutions may also be referred to as room booking displays, conference room scheduler, meeting room digital signage, or digital room signage. While the terminology varies, they all describe the same type of solution, designed to improve workspace management and communication throughout a building.
Requirements differ depending on the environment. In offices, the primary goal is to display meeting room availability and simplify room booking. In schools and universities, the displays show class schedules and room changes. In public administration, they help inform visitors about meetings, appointments, or scheduled events. More than simply displaying whether a room is available or occupied, a meeting room digital door sign should be adapted to the way the building is used.
Use cases: from meeting rooms to classrooms
In practice, digital room signs are mainly used in three types of environments:
-
-
- Meeting rooms in the workplace
The display shows the room occupancy status and allows employees to make an instant booking directly outside the meeting room. As part of a meeting room digital signage solution, digital door signs improve the workplace experience by making room availability visible at a glance, as demonstrated by the ROOMZ Display.

Key benefits of digital room signs
No matter the industry, meeting room digital signage offer several key benefits.
-
-
- Always up-to-date information
Any change made to the calendar or timetable is reflected on the display instantly. There is no need to print, replace, or check paper signs, and users no longer arrive at a meeting room with outdated information. - Better space utilization
In many organizations, meeting rooms are occupied less than 40% of the time on average. A room booking display makes available time slots visible at a glance and, depending on the solution, allows users to make an instant booking directly outside the room. - Simplified management and reduced administrative workload
All displays are managed from a centralized portal, from room assignments and display layouts to automatic firmware updates. Centralized management significantly reduces the repetitive administrative work associated with paper signs and traditional room signage. - A more professional workplace
Consistent, elegantly designed displays enhance corridors, reception areas, and meeting spaces. They provide clear, modern signage for both visitors and employees while reinforcing a professional workplace environment. - A more sustainable solution
There is no need for paper signs or laminated notices anymore. Thanks to E Ink® technology, room booking displays consume very little power. We will take a closer look at the different display technologies later in this guide.
- Always up-to-date information

The value of digital door signs depends on how your spaces are managed today. Organizations that still rely on printed timetables can eliminate hours of manual work, while companies with busy calendars but underused meeting rooms can make far better use of their available space.
The biggest benefits become apparent in larger buildings, where consistency across every meeting room and collaborative space makes all the difference. When room availability, instant booking, and centralized management work together, fewer questions end up at reception, the front desk, or the facility management team. Employees, students, and visitors can quickly see which rooms are available, what is happening in each space, and whether any schedule changes have already been updated.
How digital door signs work?
A digital door sign connects to your network over Wi-Fi and synchronizes with your existing calendar or room booking system, including Microsoft Outlook, Exchange, Microsoft 365, and Google Workspace. If your organization uses Microsoft Teams, Teams bookings are automatically displayed outside the meeting room. ROOMZ supports more than 20 room booking systems. Any change made in the calendar appears on the display instantly, and any booking made directly from the display is immediately synchronized back to the calendar.
Everything is managed from a centralized portal. Administrators can assign rooms, customize display layouts, and deploy firmware updates automatically. Getting started is straightforward, most ROOMZ customers have their first room up and running in less than an hour, including display installation.
Modern wireless solutions use E Ink® technology, also known as e-paper. An E Ink® display only consumes power when the content changes, allowing it to run for years on a single battery. When paired with an occupancy sensor such as the ROOMZ Sensor, the system can also detect ghost meetings and automatically release booked rooms that are never used.
 The ROOMZ Occupancy Sensor detects actual meeting room occupancy and automatically releases reservations for rooms that remain empty. |
E-Ink® vs. LCD: which technology is right for you?
When it comes to digital door sign hardware, two technologies have become the industry standard: wired TFT LCD panels powered by Power over Ethernet (PoE), and wireless E Ink® displays powered by batteries and connected over Wi-Fi. The differences become clear when comparing installation costs and long-term operation.
| Criteria | Wireless E Ink® digital door sign | Wired TFT LCD panel |
|---|---|---|
| Installation | Mounts in minutes on glass, wood, or walls without cables or drilling | Requires power and network cabling or PoE, often involving electrical work and drilling |
| Power supply | Battery powered, up to 5 years of battery life with the ROOMZ Display | Continuous power via electrical wiring or a PoE switch |
| Power consumption | Minimal, E Ink® only consumes power when the display content changes | Continuous power consumption, significantly higher over time |
| Readability | Nearly 180° viewing angle with a paper-like display | Typically limited to a 90° to 120° viewing angle |
| Scalability | Add new rooms, floors, or buildings in minutes | Every expansion requires additional cabling |
| Maintenance | No operating system and automatic firmware updates | Operating system requiring regular updates and security patches |
| Security | No operating system, no cables, enterprise-grade secure Wi-Fi connection, and no personal data stored on the device | Operating system with potential security vulnerabilities, cabling as a possible attack vector, and data stored locally on the device |
| The environmental impact is just as compelling. Wired displays consume up to 10,000 times more energy than battery-powered E Ink® displays. Over an eight-year period, 100 wireless room booking displays can reduce CO₂ emissions by approximately 14 tons. The ROOMZ Display is designed to last more than 10 years, while the typical lifespan of a wired TFT LCD display operating 24/7 ranges from 3 to 7 years, depending on its quality. |
Installation: cable-free digital room signage
One of the biggest advantages of wireless displays becomes clear during installation. They mount directly onto smooth surfaces such as glass, metal, or wood, with no drilling or cabling required. This makes digital room signage a practical solution for environments where electrical work is expensive, disruptive, or simply not possible, such as historic buildings, leased offices, or schools that remain in daily use.
Whether you are equipping a single meeting room, an entire floor, or multiple buildings, wireless displays can be installed without an electrician. And if your workspace changes or you relocate, the display can simply move with you, with no complex removal or reinstallation required.
 E Ink® displays, such as the ROOMZ Display, mount quickly and cleanly to smooth surfaces using an adhesive mounting system. |
What to look for when choosing digital door signs?
In practice, six criteria matter most:
- Integration with the existing collaboration tools
Does the solution support your existing calendars and room booking platforms, such as Outlook, Exchange, Microsoft 365, Google Workspace, Microsoft Teams, or industry-specific software such as school management systems (e.g. Untis)? - Installation and scalability
How quickly can a room be equipped, and how easy is it to expand the deployment? Wireless systems scale across multiple rooms, floors, and locations without requiring an electrician. - Security and data protection
Look for encrypted communication (HTTPS/TLS), privacy-conscious data display, and an ISO 27001-certified provider. The processing of personal data should comply with GDPR requirements. The ROOMZ Display does not store or process personal data locally and has no operating system, making it highly resistant to malware installation. - Total cost of ownership (TCO)
Evaluate the solution over its entire lifespan, not just the purchase price. Consider hardware, software licenses, cabling, PoE switches, electricity, and maintenance. Also factor in installation and cabling costs, typically around €500 to €1,000 per cable, as well as the cost of replacing the device at the end of its service life. - Design and materials
Digital door signs help shape the first impression of corridors, reception areas, and meeting spaces. Real glass and aluminum create a more premium look than plastic, while a matte E Ink® surface eliminates glare and resists fingerprints. - Expandability
The greatest value comes from combining digital door signs with occupancy sensors to eliminate no-shows and analytics tools that measure how meeting rooms are actually used. Solutions such as ROOMZ Advanced Analytics provide the insights needed to make informed workplace and space planning decisions.

Before rolling out digital door signs across your organization, it is worth starting with a pilot deployment in just a few rooms. This gives IT and Facility Management teams the opportunity to validate Wi-Fi coverage, calendar integration, installation, display layouts, and user adoption in a real-world environment.
A pilot project also reduces the risks associated with larger deployments across multiple floors or locations, while helping you identify the features that deliver the most value, whether that is instant booking at the display, occupancy sensing, workplace analytics, or dedicated views for classrooms and lecture halls.
 ROOMZ Advanced Analytics provides detailed insights into how meeting rooms are actually used, helping organizations make data-driven decisions to optimize their workplace strategy. |
Real-world examples: ETH Zurich, Cantonal School of Olten, and BOBST
ETH Zurich installed more than 800 e-paper displays across its meeting rooms, seminar rooms, and lecture halls, making it easy for students to find available spaces between classes. A wireless solution was essential because the university’s historic main building could not be retrofitted with cabling. Today, the ROOMZ Server is connected to more than 10 different room booking systems.
As part of a major campus renovation, the Cantonal School of Olten replaced printed timetables outside 85 classrooms with room booking displays connected to its school management software. Isabelle Berger, IT Services Manager, explains the limitations of the previous system: «Each semester, someone had to take down the old schedules from all 100 classrooms and replace them with the new ones. As soon as a change occurred, the schedules were no longer up to date.»
BOBST, one of the world’s leading suppliers of equipment for the packaging industry, modernized its headquarters in Lausanne through its New Workplace at BSA project, involving nearly 1,000 employees. The company selected ROOMZ to support its vision of a more sustainable and efficient workplace. Stéphane Mader, Head of Group Marketing & Communications & Workplace Program Manager, explains: «Choosing ROOMZ also means supporting a local company that shares our sustainable vision and our demand for quality.»
