Seems Satellite Internet has very limited bandwidth(eg each Ku-Band transponder = 506Mbps bandwidth capacity), compared to fixed Land Fiber Internet(eg each Fiber line = XG-PON or 10G-PON or 10Gbps bandwidth capacity) Eg a row of link-houses share the 10Gbps Fiber bandwidth, hence got TM Unifi Home Fiber Internet 300Mbps plan and unlimited data)
The newest 2014-launched Maxis-owned Binariang Measat 3b, which has a working lifespan of only 15 years, uses the modern Ku-Band. It's 506Mbps bandwidth capacity in each of its 48 transponders has to be shared by all the subscribers of the Satellite ISP, eg Maxis ConnectMe and TM VSAT and by subscribers of Astro Satellite TV.
....... Since Measat is owned by Maxis, it could offer ConnectMe@Home plans at 25Mbps while TM VSAT could only offer it's business subscribers 2Mbps.
So, if more subscribers, worse is the network congestion, ie much worse than 4G network congestion in city/urban areas. .......

''''''' Modern consumer grade satellite Internet service is typically provided to individual users through geostationary satellites that can offer relatively high data speeds,[2] with newer satellites using Ku band to achieve downstream data speeds up to 506 Mbit/s. ...
Bandwidth
Consumer satellite Internet customers range from individual home users with one PC to large remote business sites with several hundred PCs.
Home users tend to use shared satellite capacity to reduce the cost, while still allowing high peak bit rates when congestion is absent. There are usually restrictive time-based bandwidth allowances so that each user gets their fair share, according to their payment. When a user exceeds their allowance, the company may slow down their access, deprioritise their traffic or charge for the excess bandwidth used. For consumer satellite Internet, the allowance can typically range from 200 MB per day to 25 GB per month. A shared download carrier may have a bit rate of 1 to 40 Mbit/s and be shared by up to 100 to 4,000 end users.

Measat 3b's has 48 Ku-Band transponders with each having a bandwidth capacity of 506Mbps maximum. For each Ku-Band transponder, If >20 Maxis ConnectMe@Home subscribers(= 25Mbps plans) in Malaysia get actively online at the same time = network congestion on that transponder. Imagine if got 100 such subscribers = traffic jam = each may get only 5Mbps.
Note that Maxis Astro Satellite TV service also uses some of Measat 3b's Ku-Band transponders.
Looks like Satellite Internet is a very expensive option for the government to help rural folks in Sabah and Sarawak.Maybe, the government should go for 4G cell towers 20 miles apart and subsidized 4G parabolic grids and cell signal boosters via its GLC, Celcom.

Sararwak approves RM50mil VSAT project to improve Internet coverage - Tuesday, 22 Sep 2020
"The speed (broadband) of this VSAT technology is 30 megabits per second (mbps) including the use of WiFi, so this will make it easier for rural farmers to sell their agricultural products and to connect with buyers," he said when officiating at the groundbreaking ceremony of the new Sarawak State Farmers' Organisation (PPNS) building, here on Tuesday (Sept 22).
The Sarawak government will be deploying subsidized TM Vsat or Satellite Internet for her rural folks. Looks like Vsat has been upgraded to the Ku-band = same like Maxis' ConnectMe Satellite Internet.
