Sailortalk is a connection agnostic Optimised Transport Layer (OTL) for high latency and low bandwidth scenarios like ships and remote locations. The OTL itself is designed to optimise, fragment and allow access to local data, such as mobile communications (3G & 4G) and sensor metrics from IoT devices.

Join the evolution

The SailorTalk range

The platform consists of two elements - the local node (LN) and the global node (GN). The former is a smart hardware and software package that connects the ship or location into the global node via satellite, radio or other means of communications. The global node is a cloud-based service that has a lot of computational power and great availability to handle the requests of thousands of local nodes.

Traditionally, low bandwidth scenarios like ships don't really have many other solutions that to try to expand their bandwidth as many applications or hardware solutions treat network connections and data more like streams instead of packets in the stream. Streams are very hard and resource intensive to optimise, while packets as much easier data-logistically.

The OTL is based on the premise of "optimised everything", what can be fragmented into packets will be, what can be cached will be et cetera. On top of the layer, Sailortalk provides a selection of applications or apps.

The product is available only as a service, for great monthly price.

We are currently working on our two first applications on top of the OTL:

Voice

The first app done on the Sailortalk OTL is actually a hardware solution and an old one at that: Mobile connectivity in remote locations through the OTL. By using 3G and 4G technology, we are able to use the amazing technology that is GSM - its codecs and most of all its design that was specifically crafted for low bandwidth, high latency and poor quality environments.

Through the OTL we can easily quadruple and more the concurrent voice users, allow lower costs per minute, increase voice quality and of course using less bandwidth than before.

It also allows the users to use their standard mobile phones and removes the need to install any software.

Data Layer

Technical environments like expeditions or ship sensors collect a lot of metrics and other data, usually stored locally and being sent through email. The Sailortalk Data Layer enables the efficient way to deliver this data out of the location - naturally optimised through the OTL.

The Data Layer is basically an application programming interface (API) that handles the authentication of the requester and connects the request to the system or application in the local environment, passing it along in the most optimised way.

The Data Layer is completely agnostic on what kind of data or software it's working with, making it a great solution for ship operators, universities, 3rd party companies and others to access their data and even enable push functionality to their systems, making the data use even more efficient.

The team

Markus Sandelin
CEO

Markus co-founded Pentonet with Darryn, bringing his long entrepreneurial experience to strenghten the core team. He has been doing online things for over 20 years and has a proven track record in running both companies and technological products and projects.

His background from design and technology and an MBA from the Stockholm School of Economics provide Pentonet with a solid foundation to build upon and his major marketing experience allows the technical team to focus on the most important thing - building the best product in the world.

Darryn Trowell
CTO

Darryn co-founded Pentonet building on more than a quarter of a century of experience of mobile infrastructure within the cellular industry. Since graduating as an engineer from the Royal Air Force Academy, Darryn has held senior operations, product and development roles in wireless communications with Ericsson, Nokia, Nortel, ip.access, Zynetix, Globecomm and Quortus.

His mixture of technical skills and experience of the full life cycle of operations, from development to procurement to project management to delivery, make Darryn ideal to lead the Pentonet operation going forward.
