NB-IoT is an international (3GPP) standard and developed in such a way that it can be used by any mobile operator worldwide. Within a few years an NB-IoT network will be active in most countries, so you are assured of a scalable application of your IoT solution.
And because our network can be quickly upgraded by software updates, new releases of 3GPP for NB-IoT can also be rolled out quickly.
NB-IoT uses licensed frequencies. Because we are the only party allowed to use these frequencies, there is no interference from other networks. The licence for this spectrum will last at least until 2033. For you, it means an extremely high availability of our IoT network.
In Europe, NB-IoT uses the 800MHz and the 900MHz band. In the Netherlands T-Mobile uses the 900MHz (band 8). The nice thing is that a lot of devices and antennas are suitable for the 900Mhz band, because this frequency range has been used for GSM since 1980.
Dedicated core network
Our NB-IoT network is set up as a dedicated network separate from our 2G, 3G and 4G network. The NB-IoT network is optimized for devices that send small data messages every once in a while and need to receive data once in a while. In addition, these devices are not accessible to the network for most of the time because they are asleep. This requires a completely different setup of the network than, for example, 4G where a relatively large amount of data is streamed to the device/mobile phone and where these devices are always accessible. So even if it is very busy on the 4G network (e.g. at an event), this has absolutely no effect on the operation and performance of our NB-IoT network.
Our network is monitored 24×7 in order to be able to intervene quickly in the event of any problems and thus guarantee a very high availability of the network.
The latency when sending and receiving messages is generally less than 10 seconds. The latency is highly dependent on the coverage and load of the network. With very good coverage, the latency is often no more than a few seconds, but with a device that is underground and therefore has less coverage, the latency can sometimes exceed 10 seconds. The latencies for sending and receiving the data are the same, provided the device is not in deep sleep for receiving the message.
Low packet loss
The messages sent from the device arrive on the network in almost all cases. Coverage is also important here. In tests we performed ourselves with good coverage where 30 devices on the same antenna sent a message of 250 bytes every second, the packet loss was on average below 1%. Should this occur, then your device will send the packet again. This is taken care of by our network and technology.
