Your supervisor wants to replace the office's fiber-optic connection with a less-expensive satellite Internet service. The office depends on the link for VoIP phone calls, email, and cloud-based file storage. After researching costs you discover that a satellite plan is indeed cheaper. Why would you advise against making the change?
Switching to satellite would require rewiring the entire LAN, which would erase any cost savings.
The high latency of a satellite connection would degrade VoIP call quality.
You don't-saving money with no performance change is a great idea.
Satellite links cannot be encrypted, creating a compliance and security problem.
Geostationary satellite links introduce very high latency (often 500 ms or more) because every packet must travel about 35,000 km to space and back. That delay causes noticeable echo and talk-over on VoIP calls and degrades other real-time applications such as video conferencing. Satellite service is also susceptible to weather outages (rain-fade). The indoor satellite modem usually presents a standard RJ-45 Ethernet hand-off, so rewiring the local network is unnecessary, and normal IP-based encryption (HTTPS, VPN, etc.) works over satellite just like any other medium.
