Microwave is a type of transport sir. Cellphones use microwaves. or better uses the em spectrum between radio and hard microwaveSalamat at sinabi nyo yan.
The past decade kasi, our company had a client that implemented a system in Manila with several remote locations including Visayas and Mindanao. They did not use VPN (virtual private network). Multinational pa man din. They used "microwave" instead. Making use of "satellite" technology daw. Ayun, problema sa connectivity. Nightmare sa implementation. It was resolved eventually but after some months. I was not sure lang if this "microwave" is similar to satellite that Singson is saying as i am not involved on the technical side.
sir yung VPN is just an encryption thing. You can use vpn using sat connection.
You can use fiber and deploy vpn. Problema kasi sa satellite ay yung latency(assuming stable yung signal espescially cloudy or inclement weather or solar flares). Since radio travels around 300K kps the distance betweek ground and satellite vice versa plus young processing ng ground networks. so most likely may delay na around 2-4 sec. Saka may max limit yung data mga sat connections.
Mas reliable pa yung RadioLan keysa mga sats
