What are the different technologies?2G, 3G, 4G, and 5G are different generations of cellular network technologies, each offering varying levels of speed, capacity, and capabilities. Here's a brief overview of each:
What's happening with 2G and 3G. Are they being shut down?In New Zealand all of the cellular networks have announced plans to shut down their 3G networks to free up resources for the newer technologies. There's a summary below for each network with their plans for 3G. One NZ is the only network in New Zealand currently offering 2G services.
Spark Spark have announced that they'll be closing down the 3G network towards the end of 2025. See details here Spark 3G shutdown. One NZ One NZ have announced that they'll start to shutdown their 3G network from September 2024. See details here One NZ 3G shutdown. 2Degrees 2Degrees have also announced they will be shutting down their 3G network towards the end of 2025. See 2Degrees 3G shutdown. Join us at the upcoming Fire NZ conference and exhibition in Auckland, taking place from October 3rd to 5th. We're excited to announce that we'll be hosting a stand, showcasing our latest industry services. We invite you to stop by and have a conversation with us. We can't wait to meet you at the event!
Battery backupTo maintain uninterrupted monitoring of a buildings fire alarm system even during mains power outages, our systems are equipped with backup power sources. We utilise two distinct types of backup power sources:
Lead Acid BatteriesGeneral Information When buying a lead-acid battery, there are several important factors to consider to ensure you choose the right battery for your needs. Lead-acid batteries are used in a variety of applications including vehicles, uninterruptible power supplies (UPS), solar energy storage systems, and more. Here are some key considerations:
Selecting a replacement When it comes time to replace a lead acid battery do think carefully when selecting a replacement. Whilst it can be tempting to opt for the cheaper option, as a general rule they won't last as long or perform as well. Purchasing a more expensive option from a reputable brand will often save time and money in the long run. Super CapacitorsGeneral Information
A super capacitor, also known as an ultra capacitor or electric double-layer capacitor (EDLC), is an energy storage device that stores and releases electrical energy through the electrostatic separation of positive and negative charges. Unlike traditional capacitors that use a dielectric material to store charge, super capacitors store energy in an electric double-layer formed at the interface between a high-surface-area electrode and an electrolyte. Some of the key characteristics of super capacitors are:
Selecting a replacement If you believe that a super capacitor connected to one of our systems needs to be replaced, please contact us and we'll guide you through the process. |
