SAT365 by Comms365: managed LEO satellite for FWA, resilience and IoT

For years, satellite connectivity carried a reputation for high latency, high cost and painful setup. Low Earth Orbit constellations have changed that picture. By flying satellites a few hundred kilometres up rather than in distant geostationary orbit, LEO cuts round-trip latency to figures that are usable for voice, video and interactive applications, while delivering bandwidth that rivals a decent fixed line.

SAT365 is Comms365‘s managed LEO satellite portfolio. The important word is managed. Buying a bare satellite terminal gives you a link and little else. SAT365 adds a service wrap, deployed and supported by Comms365’s UK based Network Operations Centre, that turns the raw satellite connection into a business grade WAN with fixed IP, routing, security and failover options around it. That is the difference between a consumer dish and a managed corporate service.

Why LEO satellite, and how it compares

The case for LEO rests on three things: speed that is fit for real business use, latency low enough for interactive traffic, and a lead time measured in days rather than the weeks or months a new leased line can take. That last point is often the deciding factor. A site that needs connectivity now cannot wait for a fibre build.

Fibre still wins on raw latency and, where it exists, on cost per megabit. The point of LEO is not to beat fibre everywhere. It is to deliver a business usable link wherever fibre is impractical, and to do it fast. That makes it a strong fit for two jobs in particular: fixed wireless access, and connectivity for IoT.

The comparison people forget to run is against cellular. Before you reach for satellite, check whether 5G fixed wireless access covers the site, because where there is a usable mast in range it is almost always cheaper, lower latency and simpler to support. LEO earns its place at the sites where that answer comes back no, or where the mast itself is the single point of failure you are trying to design out. Comms365 are unusually honest about this in their own material, which notes that neither fixed line nor cellular is the right answer in 99% of scenarios and that blended designs generally win.

Not just a connection: the managed service wrap

The real value in SAT365 sits around the link rather than in it. On its own, a LEO terminal typically hands you a best effort public internet connection behind carrier grade NAT, with a changing IP address and no priority controls. That is fine for casual browsing and unworkable for most business or IoT deployments. The Continuum Constellation service wrap addresses this directly.

Why these features matter

A fixed public IP is the feature that unlocks most business and IoT use. It allows inbound access, site to site VPNs, IP whitelisting and remote device management, none of which work reliably behind shared satellite NAT. QoS lets you protect voice and video traffic when a site is busy. SD-WAN integration means the satellite link can sit alongside fibre or cellular in a single managed overlay, with traffic steered by policy. 4G and 5G failover adds a second path so a passing obstruction or outage does not take the site offline, and proactive monitoring from the UK NOC means problems are seen before the site reports them.

The failure mode your monitoring will not catch

There is one behaviour worth understanding before you deploy any LEO service. Consumer and small business satellite tariffs typically include an allowance of priority data. Once that allowance is consumed, the connection does not fail. It is throttled, in some cases to around 1Mbps down and 0.5Mbps up, until more data is purchased.

That distinction matters enormously. An outage triggers your alerting. A throttle does not. The link is still up, still passing ICMP, still green on the dashboard, and completely useless for CCTV, voice or telemetry. Your first indication is a phone call from the site. This is precisely why the managed wrap includes data usage monitoring with threshold alerting across all sites from a single view, and it is the argument that sells the service to anyone who has been caught by it once.

SAT365 as fixed wireless access (FWA)

Fixed wireless access means delivering a fixed site’s primary connectivity over the air rather than through a cable. Most people meet FWA in its 4G and 5G form, where a router at the premises connects to a nearby mast. That works well where mobile coverage is strong, and not at all where it is weak or absent. This is exactly the gap LEO satellite fills.

Because a LEO terminal only needs a clear view of the sky, SAT365 can act as fixed wireless access almost anywhere, including sites with no usable fibre, no cable and poor mobile signal. For a rural office, a new build with no infrastructure, a temporary premises or a remote facility, it becomes a viable primary connection rather than a stopgap.

Where LEO FWA earns its place

The distinction that matters here is managed versus best effort. A raw satellite dish gives you connectivity. SAT365 gives you fixed wireless access you can put a business on, with an IP address that stays put, security you can design around, and a UK team watching the link.

SAT365 for IoT and M2M

IoT projects live and die on connectivity, and the hardest sites are almost always the remote ones. A pumping station, a substation, a reservoir, a remote weather or environmental sensor, a construction compound: these are the places that generate the most valuable data and have the least infrastructure. LEO satellite gives those sites a route back to the platform.

How LEO fits an IoT architecture

In most deployments the satellite terminal does not talk to sensors directly. It provides the backhaul. An edge gateway or industrial router aggregates the field devices over cellular, wired, LoRaWAN or serial links, and the satellite service carries that traffic to the core. With a fixed IP and a VPN on the SAT365 side, engineers can reach the gateway and its downstream devices securely, run remote management, and pull telemetry into a SCADA or IoT platform as if the site were on a fixed line.

The SIM management problem at remote sites

There is a wrinkle specific to the kind of site that needs satellite. If a location is remote enough that you are flying its data down from orbit, it is remote enough that you never want to send anyone there to change a SIM card.

This is where eUICC and eSIM come in, and where the specification matters more than the marketing. SGP.22, the consumer specification, assumes a person with a screen scanning a QR code. That assumption fails completely on an unmanned substation. SGP.32, the IoT specification, replaces it with an eSIM IoT Manager that pushes profile changes to unattended devices remotely, with a rollback mechanism if the new profile fails to attach.

Comms365 are one of the few UK providers to state that they support both SGP.22 and SGP.32, from QR code provisioning through to remotely pushed profiles. If your remote sites are going to outlive your current operator contract, and they usually do, that is worth asking about at design stage rather than discovering later.

IoT and M2M workloads that suit LEO backhaul

Two ways to deploy SAT365

Comms365 offer SAT365 in two shapes, so it can suit a single quick deployment or a full enterprise rollout.

How SAT365 fits the wider Comms365 portfolio

SAT365 is rarely bought in isolation, and it is not designed to be. It sits at one end of a connectivity portfolio that Comms365 have built out since 2008, and the value usually appears where two or three of those services are combined rather than where one is deployed alone.

Understanding what else is in the box tells you what a SAT365 design can look like.

The design that comes up most often in practice is a three-layer one: fibre where it exists, cellular on an unsteered multi-network SIM as the second path, and LEO satellite as the layer that works when the first two are absent or both compromised by the same local event. SD-WAN steers between them and the platform never notices.

Applications and use cases

SAT365 spans a wide range of sectors. In each case the value is the same: connectivity where terrestrial options fall short, wrapped in the management that makes it usable for business.
