Fast internet with fibre optic lines
Just one thin fibre optic cable (to the right in the picture) is as powerful as multiple conventional copper cables (to the left in the picture). Fibre optic networks boast much faster, more stable internet access for multiple aspects of our modern lives, including telephone services, smart home products, Wi-Fi, gaming, smart TVs, online shopping and video calling.
Fibre optic cables offer data transfer rates of up to 10 gigabits per second – a rate that far outpaces that available with copper cables. Instead of transferring data using conventional electrical conduction, fibre optic cables allow data to be sent at the speed of light.
We measure the chromatic dispersion of the transmitted light pulses for quality control. In addition, we check signal transmission with the PMD measurement as standard.
Stage 1: FttC (fibre to the curb)
Fibre to the curb or property boundary. The lines are rolled out up to the grey boxes positioned at the edge of the pavement, called primary connection points (PCPs). These points connect fibre optic cables to each house’s existing copper cables. This falls under network level 3.
Stage 2: FttH (fibre to the home)
The fibre optic cable is routed directly to the house. A route is laid branching off from the street leading to the house. The cable is connected to the house through the basement or the house’s central distribution point.
The old copper lines remain in place, but are connected to fibre optic cabling over short distances. The fibre optic cable is connected as closely as possible to the house’s copper cable supply to keep the data transfer rate as high as possible.
Powerful radio networks
...are needed not only to ensure calls are easy and convenient to make on mobile networks, but also to prepare for future technology, including autonomous driving, Industry 4.0, artificial intelligence, intelligent mobility, smart farming, intelligent supply networks, e-health and future media.
Next generation mobile networks
(NGMN for short) are part of an ongoing project by mobile phone companies and mobile network providers to develop the next generation of mobile communications. The generations implemented as of 2015 were UMTS (3G) and LTE (3.9G).
5G (short for the fifth generation of wireless networks) refers to the level of mobile broadband communications and, under
ITU specifications, requires the following parameters:
We offer support for the planning and approval process:
In particular, we check whether any adjustments are needed in terms of regulations governing distances from other sites. We create reliable frameworks early on for building small cell mobile networks. We love good #planning.
Connecting fibre optics to base stations:
#BroadbandDevelopment is what we do..
Construction and setup of radio towers:
Foundation excavation and construction: tower assembly, cable installation, technology installation, setup, documentation and supply line installation...
We differentiate between data transfer rate, latency and connection density to determine the optimal wireless network in each case: eMBB or mMTC
High bit rate applications where a cell services many users, high bit rate applications like ultra high definition video streaming rely on individual users having access to high bandwidths and high capacity in a single cell. Supplying data transfer rates like these relies on technology that significantly increases spectral efficiency and requires broad frequency ranges.
Potential areas of application:
Adding many everyday objects to the Internet of Things (IoT) network. The resulting communication with control centres places high demands on network capacity in order to manage several hundred thousand registered devices per cell. In addition, radio transmission needs to be done at the highest level of energy efficiency to allow for networked sensors to have a battery life of ten years or more.
Potential areas of application:
Electromobility requires an extensive infrastructure of charging points. WirliebenKabel installs public charging stations for operator networks throughout Germany. Vehicles can be charged by connecting vehicles to chargers using a cable (conductive charging system for electric vehicles under DIN EN61851-1). Two charging station models are available:
A) Rapid charging stations will be located mainly at key central hubs for long-distance traffic to enable electric vehicle users to enjoy high-yield charging in just a short time. The combined charging system (CCS) – the EU standard for direct current rapid charging – is used.
B) Charging stations for daily commuter traffic, where only a few kilowatt hours of electrical energy are consumed. This takes longer, but protects both the battery and the environment.
