Why Vodafone NB-IoT?

LTE grade security

LTE grade security comes as standard. Ensure data and network resiliency with NB-IoT on your cellular devices.

Widely supported

NB-IoT is widely supported within the industry, from chipset manufacturers to service providers.

Two-way communication

Bi-directional communication allows you to send and receive data via NB-IoT.

164dB propagation

NB-IoT provides the deepest and furthest reach of any LPWA network.

Low power consumption

NB-IoT’s low power attribute makes it perfect for connecting smart devices where battery-life is important.

Stay connected in hard-to-reach locations.

Low frequency, high penetration

NB-IoT is a low power wide area network (LPWAN) technology that offers low frequency connectivity for long-range communication with better penetration capabilities than 2G. Narrowband IoT is designed to keep your devices connected in hard-to-reach places such as underground locations and deep urban infrastructure, meaning it is very effective for solutions such as vehicle and asset tracking in underground car parks.

A modern solution for modern businesses.

LPWAN technology

LPWA networks communicate wirelessly over long distances whilst maintaining low power consumption. Due to its wide signal coverage and maximised energy-efficiency, LPWAN is shaping the future of IoT connectivity. In fact, the number of devices connected via LPWAN is increasing at a rate of 109% each year.

  • LPWAN devices have an incredible battery lifetime, in fact they can run on batteries for 10 years+ without a single charge

  • Receive long-range connectivity, even in underground locations such as car parks and basements
  • LPWAN is low-bandwidth – most applications only require a few bytes per day

Leading LPWAN connectivity.

How does NB-IoT stack up against the competition?

NB-IoT technology utilises the licensed spectrum for device connectivity, meaning it comes with the security features used by MNOs. Competitors of NB-IoT, Sigfox and LoRaWAN, use the unlicensed spectrum where interference and security vulnerabilities are much more likely to occur, limiting the quality of service. NB-IoT gives you peace of mind when it comes to network and data security.

Developing fast.

NB-IoT is backed by leading names in IoT

There are over 140 mobile network operators (MNOs) in 70+ countries investing in NB-IoT connectivity. 90 of those operators have launched NB-IoT networks in 50+ countries, and this is expected to increase as demand for NB-IoT continues to grow across the world. At InfiSIM, we’re supporting the development of NB-IoT and are supporting any business looking to deploy this LPWAN connectivity option.


NB-IoT stands for Narrowband Internet of Things.

An NB-IoT device is any kind of IoT device that utilises narrowband technology to connect to the internet.

NB-IoT is a wireless 3GPP technology that uses low frequency to deliver connectivity to your NB-IoT enabled devices. It is an alternative to traditional 2G, 3g, 4G and 5G technologies.

Yes. In order to deploy narrowband IoT connectivity, your hardware must have a SIM slot or have an NB-IoT SIM built into the device.

NB-IoT connectivity has been recorded to cover up to nearly 15km. And due to it’s highly penetrative connectivity properties, similar distances can be expected in built up areas.
