Global cellular IoT connections hit 1 billion in 2018
• The global number of cellular IoT subscribers increased by 70%during 2018 to reach 1.2 billion.
• Until 2023, it is forecasted to grow at a CAGR of 49.4%to reach 9 billion IoT devices connected to cellular networks.
• Growth was driven by exceptional adoption in China, 63% of the global installed base.

CE level 0,1,2(level 2 correponds to 164dB MCL)
(a) CE Mode B, this is the simulation achieved using conservative receiver Noise Figures and 20 dBm Power Class UE (3GPP TR36.888)(b) CE Mode B, this is the simulation achieved using less conservative receiver Noise Figures and 23 dBm Power Class UE (3GPP TR45.820)(c) The common perception that NB-IoT offers 20 dB symmetrical link budget enhancement is not without a compromise. Max coupling loss (MCL) for in-band and guard-band modes is not symmetrical and much below the target 164dB.
3GPP target was to provide 15 dB of coverage gain for LTE-M with UE @ 23 dBm, compared to LTE Cat 1, and 20 dB for NBIoT.Coverage is increased by simply operating in 180kHz (NBIoT) or 1.08MHz (LTE-M) compared to 20MHz LTE carrier bandwidth, yielding 20dB and 11.5dB improvement respectively.

AT&T, KPN, Orange and Swisscom activate LTE-M roaming
• AT&T, Orange, Swisscom and KPN activated LTE-M roaming across their respective IoT networks, enabling connected devices to operate more efficiently across Europe and North America.
• Swisscom deployed the technology across Switzerland, while Orange’s LTE-M offering is available in France and Romania. KPN launched it in the Netherlands and AT&T operates its network across the US and Mexico.
• By the end of 2020, industry body GSMA believes LTE-M will fully cover Europe, and the companies said they expect to add more operators to the roaming agreement “in the coming months”.

AT&T and Vodafone NB-IoT Roaming across U.S. and Europe
• AT&T and Vodafone Business will open up access to their respective NB-IoT networks to make it easier for customers to create massive IoT deployments that work across the U.S. and parts of Europe.
• The inter-carrier roaming arrangement will include the country-wide NB-IoT network for AT&T in the U.S. and the Vodafone networks in Spain, Germany, Italy, UK and the Netherlands.
• It will be available to customers by the end of 2019.

Key takeways
• IoT continues to be a reliable source of growth over the next 5 years
• Hard to let 2G go in Europe, while 3G might disappear first
• North America and Asia-Pacific have already taken the move to 4G and 5G
• LTE Cat.1 is the lowest-tier, mature technology supporting Voice over LTE
• 3GPP standards are evolving in two directions: MBB and LPWA
• LTE-M and NB-IoT are an integral part of long-term 5G Massive IoT strategy
