Wireless & Mobile: Seamless Connectivity in a Connected World

Powerful WiFi networks are the foundation of modern communication.
They connect people and devices, enable flexible working, and ensure fast transmission of critical data - whether in offices, clinics, or at major events.

However, reliable WiFi is not automatic but depends on thoughtful planning - from selecting appropriate WiFi standards and security concepts to the optimal positioning of access points.

CMS IT-Consulting GmbH relies on WLAN solutions that flexibly adapt to your requirements, meet the highest security standards and are easy to manage.

Overview of WLAN standards: Wi-Fi 4 to Wi-Fi 7

Understanding and correctly implementing standards

To make your network future-proof, we rely on state-of-the-art solutions that enable seamless migration to new standards. WLAN technologies are constantly evolving to ensure higher speeds, better stability, and enhanced security.

Wi-Fi 4 (802.11n)

Supports both 2.4 GHz and 5 GHz and is available for the first time with MIMO technology (Multiple Input Multiple Output) for increased bandwidth, range and speeds up to 600 Mbit/s.

Faster, more stable, more secure: Why modern Wi-Fi technologies are worth it

Maximum Speed

Current WiFi standards enable fast data transfer - crucial for cloud applications, streaming and data-intensive processes.

Optimized Stability

Technologies like MU-MIMO (Multi-User Multiple Input Multiple Output) and OFDMA (Orthogonal Frequency Division Multiple Access) ensure more efficient bandwidth utilization and smooth connections.

Increased Security

With modern encryption methods like WPA3, WLAN networks are better protected against unauthorized access and cyber attacks and seamlessly integrate into your security concept.

Lower Latency

Low latency is crucial, especially for real-time applications such as video calls, virtual reality, pick-by-voice, or IoT integration. This ensures smooth interactions and an optimal user experience.

    Flexible Guest WLAN

    Individually adjustable access rights for guests, partners, or customers without compromising the internal network.

WLAN Security - Protection for Your Network

A modern Wi-Fi network must not only be fast but also secure. With strong encryption methods, access controls, and network segmentation, we prevent unauthorized devices from accessing the network or data from being compromised. These security measures are especially essential for critical infrastructure (CRITIS).

  • Encryption and Authentication: WPA3 ensures secure data transmission with "Forward Secrecy" and robust authentication procedures.
  • Network Access Control (NAC): Controls which devices and users gain access to the network - dynamically and role-based.
  • Segmentation: Guests, employees, and sensitive areas should be strictly separated to minimize potential attack surfaces.
  • Advanced Security Measures: Best practices include Intrusion Detection/Prevention systems to detect intrusion attempts and a Zero Trust strategy, where every connection is fundamentally considered potentially insecure.
  • IoT Security: More and more companies are using IoT devices that need to be seamlessly integrated into the WLAN. Our solutions enable secure identity management and segmentation of IoT devices.

Your benefits at a glance

  • Reliability and Security

    • Redundancy through dual controller setups: Uninterrupted operation through flexible data forwarding from access points - either directly to a controller or locally to the next switch.

    • Private cloud for sensitive areas:   For companies with high data protection requirements or critical infrastructure facilities, we offer solutions that can be hosted in a private cloud - as a secure and controllable alternative to the public cloud.

    • Highest security standards: Upon request, we integrate Network Access Control (NAC) and state-of-the-art encryption and authentication protocols such as WPA3.

  • Efficiency and cost optimization

    • Easy Administration: Cloud-based platforms reduce administrative effort and enable central control.

    • Optimized Costs: Reduced hardware requirements and simplified maintenance save time and money - especially when you rely on our Managed WLAN service.

  • Flexibility and scalability

    • Adaptable to your requirements: Our networks grow with you – from a few access points in offices to large locations with multiple controllers.

    • Industry-specific solutions: Optimized networks for logistics (e.g., seamless roaming for the use of handheld scanners or real-time data transmission to the warehouse management system), healthcare (e.g., mobile rounds, streaming options for patients and secure integration of medical devices) or smart cities (networking of urban infrastructures such as traffic systems or surveillance cameras)

  • All from one source

    • Complete solutions: Planning, surveying, installation, documentation, and follow-up - with just one point of contact.

    • Experience matters: With over 20 years in WLAN planning and optimization, we ensure that your networks are reliable and efficient from the start.
