R&M – A Kit for 5G Networks

The specialist magazine CONNECTIONS No. 64 from R&M provides information on optimal cabling for mobile communication cell sites and 5G antennas.


R&M is rolling out a complete program for the 5G market. The globally active developer and provider of high-end infrastructure solutions for data and communications networks based in Wetzikon, Switzerland, reports on this in its latest specialist magazine CONNECTIONS No. 64. R&M is currently launching the CONEXIO product family. This is a kit for power and fiber optic cabling for mobile communication cell sites and 5G antennas. R&M will also be presenting innovative outdoor connectors for the fiber optic connection of antennas and FTTH participants. The cover story explains the background and recommendations for expanding 5G. Market participants learn how to cable their mobile communication cell sites and 5G infrastructures in a cost-effective, fast, and future-proof manner.

R&M wants to make a strong contribution to global climate protection targets. This is why the R&M magazine is also dedicated to the question of how to reduce power consumption and greenhouse gas emissions. Datacenter providers can find out how to control the cooling air in computer rooms more precisely and thus save energy and costs. CMO Andreas Rüsseler describes how fiber optic networks can help modernize the power supply. R&M is convinced that the expansion of fiber optic networks can speed up the transition to renewable energy sources. This is just a selection of what can be discovered in the latest specialist magazine from R&M.

CONNECTIONS No. 64 is available in print and as a download.

Every cell site is different. Topologies, climate zones, cellular applications, business models, standards and installation methods differ. Masts, RRH’s and base stations have variable, differentiated material requirements.

Existing 4G cell towers will be packed when the complex nationwide 5G rollout is added. FTTA/PTTA often requires clever cable routing from access networks to cell sites.

In conclusion, the development and expansion of fiber optic and power infrastructures for 5G and mobile communications require site- and operator specific system solutions.

They can be ideally implemented with a universal FTTA/PTTA/HTTA modular system.

It is called CONEXIO and comes from R&M.



EMR Additional Notes:

  • 4G & 5G: 5G is the 5th generation mobile network. It is a new global wireless standard after 1G, 2G, 3G, and 4G networks.
    • 5G enables a new kind of network that is designed to connect virtually everyone and everything together including machines, objects, and devices.
      • First generation – 1G
        1980s: 1G delivered analog voice.
      • Second generation – 2G
        Early 1990s: 2G introduced digital voice (e.g. CDMA- Code Division Multiple Access).
      • Third generation – 3G
        Early 2000s: 3G brought mobile data (e.g. CDMA2000).
      • Fourth generation – 4G LTE
        2010s: 4G LTE ushered in the era of mobile broadband.
    • 5G has started hitting the market end of 2018 and will continue to expand worldwide.
    • Beyond speed improvement, the technology is expected to unleash a massive 5G IoT (Internet of Things) ecosystem where networks can serve comm
    • 5G speed tops out at 10 gigabits per second (Gbps).
      • 5G is 10 to x100 faster than what you can get with 4G.
    • The main evolution compared with today’s 4G and 4.5G (aka LTE advanced, LTE-A, LTE+ or 4G+) is that, beyond data speed improvements, new IoT and critical communication use cases will require a new level of improved performance.
      • For example, low latency provides real-time interactivity for services using the cloud: this is key to the success of self-driving cars, for example.
      • 5G vs 4G also means at least x100 devices connected. 5G must be able to support 1 million devices for 0.386 square miles or 1 km2.
      • Also, low power consumption is what will allow connected objects to operate for months or years without the need for human assistance.
      • Unlike current IoT services that make performance trade-offs to get the best from current wireless technologies (3G, 4G, Wi-Fi, Bluetooth, Zigbee, etc.), 5G networks will be designed to bring the level of performance needed for massive IoT.


  • Fiber Optic Cable:
    • Fiber optic cables possess a center glass core surrounded by multiple layers of protective materials. They avoid electrical obstruction by transmitting light instead of electronic signals, making them perfect for environments with large amounts of electrical interference. Fiber optic cables have become the standard for connecting networks across buildings because of their resistance to moisture and lighting.
  • hielded Twisted Pair (STP) Cable:
    • Often referred to colloquially as simply ethernet cables, STP cables employ a special type of copper telephone wiring used for business installations. An external shield functioning as a ground is added to the standard twisted pair of telephone wires.
  • Unshielded Twisted Pair (UTP) Cable:
    • Unshielded twisted pair (UTP) cables are broadly used in the telecommunications and computer industries as ethernet cables and telephone wires. In a UTP cable, conductors forming a single circuit are twisted around one another to cancel out electromagnetic interference (EMI) from external sources.
  • FTTx:
    • Fiber to the Home (FTTH), Fiber to the Building (FTTB), Fiber to the Premises (FTTP) and Fiber to the Curb (FTTC), termed as FTTx are various technology and deployment options developed to enable reach of fiber as close to the user location as possible to provide high speed data and voice services.
    • Fiber to the home (FTTH) is the delivery of a communications signal over optical fiber from the operator’s switching equipment all the way to a home or business, thereby replacing existing copper infrastructure such as telephone wires and coaxial cable.
    • FTTP and FTTH are two different abbreviations for the same thing. FTTP stands for ‘fibre to the premises’ and FTTH stands for ‘fibre to the home’. … Unlike FTTC, FTTP broadband is delivered via fibre-optic cables not only as far as the cabinet, but across the entire span to your home or business.
    • Fiber-optic cables are less susceptible to glitches than traditional copper wires and can withstand the shock and vibration from inclement weather. FTTH is considered “future proof” and offers the flexibility to deliver additional services in the years to come.


  • Key Differences Between Copper Cable and Fiber Optics:
    • Data transmission speed of a fiber cable is comparatively more than that of copper cable. Copper cables are nearly 31% slower in data transmission than fiber cable.
    • A copper cable transmits the data through it in the form of electrical pulse i.e., due to the movement of electrons. As against in a fiber optics, the data transmission is the result of movement of photons thus it transmits in the form of light pulses.
    • The bandwidth provided by a copper cable is less than that of the fiber optics. Thus, a copper cabling meets the industry standards and provides a performance of up to 10 Gbps.  However, a fiber optics due to its large bandwidth possess better performance of up to 60 Tbps and above.
    • The energy consumed by a copper cable during its operation is somewhat greater than 10W but on the other side, fiber optics consumes less energy i.e., around 2W per user.
    • The lifespan of a copper wire is approximately 5 years as it gets easily affected by temperature variations and other environmental factors. However, fiber optics possess a lifespan of 30 to 50 years.
    • As fiber optics are difficult to be tapped as compared to copper cables thus proves advantageous from the security point of view. Due to this reason fiber optics are widely used for data transmission at present time.
    • A fiber optics allows transmission of data at a much faster rate as compared to copper cable.
    • The installation and maintenance cost of a fiber cable is more than copper cable.
