At CSL we have over 25 years' experience in managing Critical Connectivity services for the retail, automotive, healthcare and critical national infrastructure sectors.
Over the course of the last few years we have become a more specialised Critical Connectivity company. Our alarm signalling DNA and experience dealing with emergency services has helped us to build best in class IoT solutions for some of the world's largest and most complex organisations.
As the UK's leading connectivity provider to the telecare, security and fire industries, we know that resilient connectivity means more than just uptime to the people who rely on it. It means understanding the impacts of change, and the alterations to environments that are needed as a result of that change. This trust, expertise and knowledge is accelerating our growth towards becoming Europe's leading Critical Connectivity provider.
Managed 4G roaming SIMs suitable for any application with the ability to access to all major networks.
CSL's Connectivity Management Platform (CMP) allows our customers to access data from their M2M estate, making managing their IoT solutions a more efficient experience.
IoT nirvana is getting your connected devices to do a job so that you don't need to, this isn't something that happens instantly though as both people and machines need to learn patterns and behaviours in order to a) make recommendations and b) learn what decisions to make.
Manage your SIM estate on app, mobile and desktop to ensure that the lifecycle of your solutions is available to control on the go.
Our device management portals and APIs allow you to integrate, access and control your connections.
We connect, control and secure the Internet of Things. The world of connectivity is ever changing. And we're constantly developing, evolving and transforming our services to bring our customers more powerful solutions.
We specialise in SIMs and SIM technology. The IoT industry is rife with terminology that is used interchangeably, and often incorrectly. If you're confused about eSIM, MFF2, WLCSL (which are all forms of embedded or integrated SIM cards) we can help. Many IoT devices still use removable 2FF, 3FF and 4FF formats which are the triple cut SIM that you'd typically find in your Smartphone (FF just means Form Factor, or shape/size).
IoT Routers, 4G Routers, LTE Routers... these are all essentially the same thing. There are many different options to suit the use case needed, so please get in touch to discuss your needs. Although all IoT Routers essentially do the same job (provide connectivity with an IoT SIM) they need to be configured correctly e.g. for indoor or outdoor use and/or weak signal.
VoiceLink converts PSTN calls to 4G VoLTE, ensuring analogue systems are future-proofed and can continue to make voice calls. The solution creates a bridge between the old and new technology, and allows existing devices to continue working after the PSTN Switch-Off.
VoiceLink is the ideal solution for lift alarms, found across retail, local councils, hospitals and business premises.
