Weather, Availability and Range
Loea’s 70/80GHz millimeter wave products provide the highest weather availability than has been possible with any other Gigabit Ethernet wireless technology.
Unlike Free Space Optics which is prone to network outages in fog, dust, snow and even light rain, Loea’s system is only affected by very heavy rain. In fact, for a 1km (0.6mile) deployment, roughly 100mm/hr (4in/hr) of rain – near monsoon conditions – would be needed to cause interruption of a Loea link. While Loea can offer 99.9% availability at approximately 3km (1.86 miles), FSO systems can only provide 99.9% availability at 300m (1000 feet).
60GHz millimeter wave technology is very sensitive to oxygen in the air (oxygen absorption) and based on statistical weather information is only effective to about 800m (0.5 miles) with 99.9% availability.
Other wireless technologies including microwave and unlicensed RF, lack the bandwidth offered by the Loea solutions.
The range vs. weather availability performance of Loea's millimeter wave links is calculated based on rain rate statistics for different regions. To show how these rain statistics vary geographically, different rain rate regions are used (Crane rain zones), which partition the United States into different areas depending on average rain statistics.
Shown below are maps of the United States colored to reflect the Crane rain zones. The numbers over each region represent the maximum distance a Loea L2500 ink could be deployed to achieve the availability stated.
NOTE: As international regulations become finalized, similar maps will be created
NOTE: Exact ranges can vary depending on location, environmental conditions and other factors.
