CSL Outpost

Multi-path connectivity for critical or remote sites

Outpost is a fully managed service that bonds up to four mobile connections, plus satellite and fixed-line where needed, into one resilient link. You get more bandwidth than a single connection, and if one network fails, your site stays online.

Why does connectivity keep dropping at a remote or temporary site?

Multi‑path Connectivity

Bonded connections give more bandwidth and no single point of failure.

Fully Managed Service

Monitored and supported end-to-end by CSL, backed by 30 years in Critical Connectivity.

Built for Tough Sites

Rapid to deploy and designed for remote, temporary and high-risk locations.

Why satellite alone is not resilient, and what to use instead.

Satellite is a good way to reach places other networks don’t, but any single connection can be disrupted by weather, congestion or a fault.

Outpost doesn’t depend on one path. It runs several independent mobile connections, adds satellite or fixed-line where a site needs it, and switches automatically if any link weakens. You get satellite’s reach without making it your only lifeline.

Where network redundancy is used

Waiting for fibre installations

Get online from day one. When fibre arrives, Outpost becomes your backup.

Construction sites

Site offices, CCTV and access systems connected from the first day, not next month.

CCTV and access control

A dedicated, resilient connection so cameras keep recording and doors keep working.

Temporary sites and events

Business-grade connectivity without long contracts. Deploy fast, move on when done.

Rural locations

Dependable connectivity where fixed-line is slow or unavailable.

Business continuity

An independent backup path that takes over automatically if your primary line fails.

Outpost FAQs

If you can’t find what you need, our team is happy to talk through your requirements.

CSL Outpost is a fully managed connectivity service for sites that don’t have fast or reliable broadband. It combines multiple 4G, 5G, satellite and fixed-line connections into a single resilient service, so your site stays online even if one network fails.

Outpost units are built for rapid deployment, so sites can have business-grade connectivity from day one. Lead times depend on the location and order size, but our commitment is to get your site connected as soon as possible.

Each unit has four independent cellular modems, each with its own SIM. Traffic is routed dynamically across the available paths. If one connection drops, the others take over automatically, with no manual intervention and the site keeping the same IP address.

Outpost can use any available mobile networks, satellite and fixed-line connections, with up to four mobile connections managed as one link. Using multiple networks means you’re not reliant on any single provider’s coverage or availability. In terms of mobile technology, 4G is standard and 5G is optional.

Yes. Outpost is designed for locations where fixed-line broadband is unavailable or unreliable. Combining several mobile networks, with satellite as an option, gives it the best chance of strong connectivity where other services struggle. A site survey or coverage check can confirm performance before deployment.

Yes. Outpost can run alongside your fixed line as an independent backup path and take over automatically if the primary connection fails. Many customers keep Outpost in place as resilience once their fibre is installed.

Yes. Outpost uses private networking, encrypted traffic and isolated data paths, which makes it suitable for security systems and other critical applications that can’t tolerate outages.

Outpost is designed for temporary and pop-up sites as well as permanent ones, so short-term projects can get business-grade connectivity without being tied into a long fixed-line contract. Speak to our team today to understand how we can support your specific requirements.

Yes. Outpost works for a single site or a multi-site estate, with consistent hardware and central management by CSL. Its industrial-grade units are built for harsh, remote and mission-critical environments.

No. The same IP address is used throughout, even when the backup paths are used. This ensures that firewall rules and monitoring don’t break when a connection drops.

Yes. Each Outpost unit has 16GB of memory and 512GB of solid-state storage, so it can do more than provide connectivity. It can run applications such as firewalls, file servers or machine-vision software directly on site. That means less extra hardware to install, and the data can be processed where it’s created.

Outpost is built so that one fault can’t take everything down. It can combine connections from several mobile networks, as well as satellite and fixed line, so your site doesn’t depend on a single provider or a single piece of infrastructure. If one network has an outage, traffic carries on over the paths that are still working.

Everything you need to keep the site connected. CSL handles installation and configuration, and our network operations centre monitors the service 24/7. If a unit develops a fault, we replace the hardware. You get one point of contact for the whole service, with no need to manage networks or equipment yourself.

Satellite is a great way to reach remote sites, but on its own it’s still a single connection. Weather, a blocked view of the sky, congestion or a terminal fault can take it down, and then your site has no fallback. Outpost removes that risk. It combines up to four mobile connections on different networks with satellite where it’s needed, so if one path weakens, traffic switches to the others automatically. You keep one IP address, so your firewalls and monitoring don’t break, and CSL monitors the whole service 24/7. You get satellite’s reach with something behind it.

Yes. Each of the four SIMs can operate on a different mobile network, so a fault or loss of coverage on one network does not affect the others. That network diversity helps keep your site connected if a mobile network experiences problems.

Bonding and resilience work together. Outpost combines the available connections into one managed link. If one connection fails, its traffic is redistributed across the remaining connections, so the loss typically reduces available bandwidth rather than interrupting the link.

They provide additional connectivity paths where mobile coverage alone is not sufficient or greater path diversity is required. Satellite and fixed-line connections can be incorporated into the bonded link and managed as part of the same service.

Yes. Outpost is designed for higher-bandwidth applications such as CCTV, video analytics, operational monitoring and large file transfers. CSL will recommend an appropriate mix of connections and data allowances based on the requirements of your site.
