The expansion of fibre optic networks in Germany is progressing slowly, especially in rural and remote areas. The reasons for this are complex: high investment costs, low profitability, bureaucratic hurdles and limited construction capacity. Nevertheless, the demand for powerful, stable and fast Internet access is greater than ever – for businesses, public authorities and private households. This white paper highlights the reasons for the expansion bottleneck, presents alternative wireless solutions and explains why radio technology – particularly in the form of AZG Tech's innovative mesh and pearl chain architecture – is currently the most attractive solution.

There are situations in which it is desirable to temporarily set up a greenfield network infrastructure, for example to
• provide connectivity for large numbers of people at major events,
• ensure communication for security forces at major events, or
• provide network coverage in disaster areas.

The devices in the MRX series (mesh nodes) are designed to establish a secure and reliable network infrastructure. This document describes the security features and protocols used by the MRX software.

The MRX.CraneRadio system from AZG Tech offers digital data transmission to mobile and tower cranes. The range between transmitter and receiver is approximately 200 metres.
As with any radio system, connection problems can occur if the transmitter and receiver no longer have a line of sight because buildings or similar obstacles are ‘in the way’. Especially with cranes, this so-called ‘demolition edge’ can naturally occur quickly during operation.

When operating an overhead slewing crane, especially one with a great height and long jib, crane operators encounter recurring problems, the solutions to which are outlined briefly here.
Particular attention is paid to the line of sight between the crane operator and the load or hook block.
