Do any of these newer satellites use laser as uplink? From: Eric Kuhnke Sent: Tuesday, February 23, 2016 12:25 PM To: [email protected] Subject: Re: [AFMUG] Viasat-3 going up
An o3b terminal is an identical pair or motorized, tracking 1.8, 2.4 or 3.0 meter sized dishes. Make-before-break connection. There are some good videos online illustrating how it works.

Multiply that by 4 (CPE -> Sat -> Gateway -> Sat -> CPE) and add a couple ms for frame processing, and you’re at 110ms latency to the provider.

Very interesting stuff.

For locations anywhere below 45 degrees latitude o3b provides end to end trunking at a lot less latency, and lower prices then geostationary systems. Viasat and other owners of geostationary capacity have been required to drop the monthly recurring prices for wholesale transponder capacity. The big difference being that an o3b terminal is too expensive by far for an end user, it would be typically used by a medium to large sized Wireless ISP using point-to-multipoint technology for the individual customers. For example a WISP on a pacific island nation state that has no submarine fiber access.
