FSO or RF?
Frequency Division Multiplexed RF
A little over a decade ago when we decided to specialize in true, full duplex ultra highspeed point-to-point technologies, FSO was just about the only act in town. The alternatives were limited to lease line, buried fiber, licensed microwave, or else just settling for a low end 802.11b (2.4GHz) “consumer grade” low speed link.
It made the choice pretty straight forward. When timing, budget, and true performance requirements were assessed; one of the above popped up to the top of the list pretty quickly.
Jump up to the present: the alternatives now include a vast array of options. And selecting an optimal technology, reliable manufacturer, experienced integrator, plus a source for support tomorrow can be daunting.
In a nutshell, here is a brief “high-altitude” technology comparison that may be helpful:
|802.11 Type RF||Time Division Multiplexed RF||Low cost / long distance||Lower throughputs (<100 Mbps, latency, major interference issues|
|802.3 Type RF||Frequency Division Multiplexed RF||True 1.0 GigE full duplex||Higher cost, shorter distance|
|Free-Space Optics||Fiber optics without the fiber||True 1.0 GigE full duplex, low cost||Shorter distance|
So, which should you select? It really gets down to how you will use the link, which likely drives your priorities:
-Availability requirement (9’s)
And in addition to the above, your particular physical environment (geographic location, mounting, link distance) also impact both optimal technology selection, as well as make/model alternatives.
Wouldn’t a model-neutral, field experienced recommendation come in handy?
