ExtendMM
™
This chapter describes the ExtendMM feature – extended range solution that allows
delivering Gigabit throughput over interference-free millimeter waves for long distances
by using a Sub-6 GHz radio link backup.
How does it work? By combining any Siklu EtherHaul millimeter wave radio with 1ft.
antenna, any sub-6 GHz radio and Siklu’s advanced networking capabilities. With a
single click you can turn the two radios into an extended link solution that delivers the
capacity you need over the distance you require.

ExtendMM
™ Description
Siklu’s ExtendMM™ creates an always-on, all-weather, extended range connection by
combining any Siklu EtherHaul-1200 millimeter wave radio (1ft. antenna) with any sub-6
GHz radio. With a single click you turn the two radios into a single high-performance
long-distance link.
Most of the year you will benefit from 1 Gbps over the interference-free millimeter
wave EtherHaul link. The sub-6 GHz link will be in stand-by mode.

Criteria
When a significant rain event happens, the ExtendMM™ solution automatically switches
the high priority traffic, hitlessly, from the primary EtherHaul path to the sub -6 GHz
path. As the rain cell passes, the link immediately returns to Gigabit speed. No
additional networking equipment is needed. The EtherHaul powerful, integrated
networking engine does everything for you.
As the capacity of the sub-6 GHz link is lower than the 1 Gbps capacity of the EtherHaul,
the ExtendMM allows to leverage the EtherHaul traffic prioritizing capabilities extending
the availability of the high priority traffic. When the significant rain event happens
activating the adaptive capabilities of the EtherHaul. When the EtherHaul capacity
reaches the configured threshold, the high priority traffic is forwarded to the sub-6 GHz
link. Switching the traffic routing to the sub-6 GHz link is done hitlessly by the EtherHaul
