4G / 5G
Peplink routers and external MIMO antennas for stable throughput at the dock and offshore.
VHF, AIS, 4G/5G, Wi-Fi

Expertise
Communication
Onboard communications are safety (VHF, AIS) as much as operations (4G/5G, Wi-Fi, marina). SEMA installs and repairs these layers as one system: antennas, routers, Guest/Crew separation, and coverage without dead zones.

Questions
Can guest Wi-Fi be separated from the crew network?
Yes. It is recommended: bandwidth, security and peace of mind for vessel operations.
Do you also install external antennas?
Yes. Placement, waterproofing and RF cabling matter as much as the router itself.
