Salamat 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.
Microwave is a type of transport sir. Cellphones use microwaves. or better uses the em spectrum between radio and hard microwave
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

sa 2018 technology, anu na pros and cons ng fiber vs satellite?

sa tingin ko pampagulo lang yung sat option. These bunch of clowns "Unless the discovered or have the state of the art technology" are trying to market something that they dont have a thorough understanding. Kasi may nabasa or may nagsabi, atak na ng atak. If there option is good, they why the heck are other more richer and developed countries not using it as a primary?

Sa data pag VSAT gagamitin, dali lang talaga ang pag deploy. pwede nga na 1 week 100% coverage na pero sino ang kukuha pag malaman gaano ka mahal at high latency yung net?

heres a good perspective on sat internet specially at home

In the past years, yung DPWH gumagamit ng SATCOM thru PLDT leased line kaso yun nga sobrang taas ng latency minsan RTO pa. Naobserved ko yan nung nagtest ako sa isang DPWH site somewhere in Visayas region. Buti na lang pinalitan na rin kasi gamit ang PTP antenna direct sa isang malapit na Smart Cellsite. Problema rin ay yung fiber optic rollout na umaabot ng taon bago maimplement dahil sa red tape at ROW. Kaya yung SATCOM talaga ay pang remote area lang talaga ang applications. Gungg0ng kasi yung ibang IT at sales people, pagmamalaki yung SATCOM para gamitin sa isang area na possible naman lagyan ng FOC at Microwave para makatipid daw pero in the long run sakit ng ulo ang dulot sa end user.

kung remote , immediate , tipiran , i rather do long range wifi using yagi or parabolic. abot pa ng 40 km at di pa ako magbabayad ng sat access

just build a national broadband system
As mentioned previously, the government has a GovNet established in MM and MC using fiber already. Currently being expanded coupled with additional regional GovNet centers.

Thank you for your posts/ replies.

All the while i thought VPN uses purely fiber. Puwede pala VPN using satellite.

sat kasi no need huge ground infra. Example satellite phone saka yung cignal catv

That explains why Singson is saying 100% agad so hindi na sila gagamit ng cable(fiber). But how good will the service quality be for phone users. Maybe, they are thinking, Pinoys are more into text messaging than voice so okay lang kung may delay.

Again, its the end user that suffers.

Sooner or later the query has to reach a ground based router and the response has to be transmitted from this router to the satellite. This can be achieved much faster with terrestrial cables like fiber instead of satellites. As jjdns said, this adds extra latency, not just the extra distance it has to travel but also probably change in time due to gravitational differences, and I actually donÂ’t know how big the buffers on these satellites are. There are definitely more routers on this planet than satellites
Also adding DNS queries just further complicates it. Nah, just build a national broadband system and put up some telecom towers in remote municipalities so people can utilize wireless routers instead. Speed might not be top not notch but itÂ’s probably infinitely better than what they currently have as itÂ’s probably just a couple of kb/s to zero
So that venture by the government with Facebook was the step in the right direction.

On another note, i notice whenever i query about Philippines using google.com (NOT google.com.ph), among the first five search results are links to articles by Rappler. ABS-CBN and Inquirer also appears but not all the time. But Rappler, consistent. Try nyo. ABS, philstar and inquirer, i will understand but Rappler is always there all the time. Yung ibang links, SCMP, Straits Times, Wall Street journal, NY times, Wash Post, etc then Rappler. Lakas ni Maria ha. Down naman ang engagement sa site nya. I hope i am just paranoid. Please correct me if you do not have the same experience.

Why would I believe singson. He aint got the experience or background.
Singson is like the typical pinoy businessman.
Seal the deal, Tackle with the problems later

^ Anything na medium of communication pede ang VPN basta IP-based yung gagamitin na media
Exclusive IP. As a person with limited technical background, I have this crazy notion that for a line to be secure, dapat naka kable kasi if transmitted by air, pwede ma intercept. Yes funny but i really thought it was. 😂

Anyway, thank you for sharing.
