Allgon Microwave has since 1999 pioneered integrated Ethernet data connections with licensed microwave radio solutions, becoming part of the Advantech group in 2005. Focus on high performance, high quality and high functionality has positioned the company firmly as the native Ethernet supplier. Now this position is moved forward with the launch of the new family of high capacity systems: AMR Transcend. With the innovations implemented in the new AMR Transcend portfolio, inherent performance limitations of high capacity systems are tackled. In line with the company history, this again allows for longest possible hops, smaller antenna sizes and best possible throughput and availability in the market. This is offering customers lowest cost of ownership at best possible performance.

Adaptive Coding & Modulation
As the name shows, the coding and modulation of the microwave system will adaptively and errorless adjust to changing environmental conditions. This means that instead of losing the connection due to heavy fading, ACM will adjust the radio performance to maintain the connection and increase the total up-time and availability. The system monitors in real time the performance and upon reaching the performance threshold, the system automatically adjusts the coding and modulation in order to maximise the capacity-availability ratio at any given time. The adjustment is made in 18 steps and improves the system fade margin with up to 19 dB. This is unique for licensed microwave radio.
