The 4G LTE Cat-M1 band and the '5G' NB-IoT band being rolled out with mobile phone 5G bands are the bands the networks intend you to be using for machine-to-machine (M2M) products. They offer the basic level of service required for these products and in return the networks charge very little for using them. NB-IoT is not accessible using mobile phone SIM cards; you need SIM a dedicated IoT to access them. These SIMs won't be connected to the Public Switched Telephone Networks (PSTN) so dial-to-open with your cheap PAYG SIM is not an option on these modern networks. You...

If you have a traditional alarm dialler/communicator that sends SMS messages and makes calls from the actual unit using a mobile phone SIM, then you won't know if it stops working until it's too late. This is one of the reasons we created the cloud dialler... If it's our cloud server sending the messages and making the calls we tell you when your dialler goes offline. You fit an alarm dialler to alert you to critical events that are happening when you're not there. If your dialler is responsible for telling you what is happening, how will you know when this...

4G Keypad Intercom Development   'Have you got a keypad intercom yet?' Well yes we do! It only took 8 years. We designed the simple 1-button 4G intercom with a keypad expansion in mind. In fact we had a non-working mock up of the keypad unit around the same time we launched the 1-button version. In practice though it took quite a few changes to the basic design which we will examine here. Our chosen keypad features a die-cast metal enclosure designed to be mounted with screws through the front panel. Having screws appear on the front panel looks a bit...
