What are three modes of operation applicable to NB-IoT?
NB-IoT can be deployed in three ways: in stand-alone operation, guard-band operation, and in-band operation.
How many years will 4G be around?
4G will be around for years to come as we have seen with 3G. Mobile service operators still - albeit in very few areas - offer 3G services. So 5G will not mean the end of 4G.
How much does NB-IoT cost?
One rate - unlimited data for $30/year*
LTE-M / NB-IoT is optimized specifically for IoT applications.
Will older phones work with 5G?
If you own an older cellphone with 3G, be aware that in 2022, some of your electronics will stop working because of a 5G upgrade. If you own an older cellphone with 3G or a Kindle, be aware that in 2022 some of your electronics will stop working because of a 5G upgrade.

What is NB-IoT guard-band?
This system, based on Long Term Evolution (LTE) technology, can be deployed in three operation modes - in-band within LTE carrier, in the guard-band of LTE carrier, and stand-alone. Guard-band deployment allows the operator to support NB-IoT without requiring new spectrum and with minimal impact to LTE.
Is LoRaWAN free?
LoRaWAN® specification is an open standard, it is open to anyone, free of charge, and there are no license fees or other fees associated with its usage. There are open-source implementations of the LoRaWAN® stack, both on the device side, and the cloud side. In that sense, LoRaWAN® is free to use.
What is cat-M1?
Cat-M1, also known as LTE Cat-M, is a low-cost LPWAN technology developed by 3GPP as part of the 13th edition of LTE standard. It's a complementary technology to NB IOT, with faster upload and download speeds of 1Mbps and lower latency of 10 to 15ms.
Which LTE Cat is best?
Data rate requirements and power consumption are in most cases pre-determined by end application. LTE Cat 4 offers an uplink speed ten times faster and a downlink speed fifteen times faster than LTE Cat 1 measured in Mbps. In examining speed and power requirements Cat 4 devices are better aimed at higher data rates.
Which NB-IoT physical layer channel is carried in subframe 0 of every NB-IoT frame?
Narrowband Physical Broadcast Channel
