Last year ARM went on a bit of a buying spree thanks to the financial help of its holding company, SoftBank. One of the companies that it scooped up was that of Simulity Labs for around 12 million pounds. The company was developing IoT security products based on eSIM technology and a robust OS that provides provisioning on a cellular network.
Many believe that the nearly ubiquitous cellular networks that surround us are the key to truly successful IoT products. There are massive cellular deployments around the world. It is a well regulated spectrum. Security through SIM cards is a well known and understood process. It is not impossible to break this security, but it is questionable if it is worth the time and effort to do so.
ARM has gone ahead and provided the means to productize and push this technology with the aim of providing a vast, secure IoT infrastructure that would be relatively easy to rollout with current cellular networks. There are multiple parts to this technology, but ARM is hoping to offer an all-in-one solution that would provide an inexpensive platform for OEMs and Mobile Network Operators (MNOs) to roll out products on.

Qualcomm has officially unveiled the development of a new 5G modem with the Snapdragon X50, which targets OEMs and early 5G development. The X50 supports milimeter wave (mmWave) technology initially, and rather than replace existing LTE solutions the X50 is designed to work alongside LTE modems integrated into Snapdragon SoCs, for a seamless handoff between 5G and 4G networks.
"The Snapdragon X50 5G modem will initially support operation in millimeter wave (mmWave) spectrum in the 28GHz band. It will employ Multiple-Input Multiple-Output (MIMO) antenna technology with adaptive beamforming and beam tracking techniques, which facilitates robust and sustained mobile broadband communications in non-line-of-sight (NLOS) environments. With 800 MHz bandwidth support, the Snapdragon X50 5G modem is designed to support peak download speeds of up to 5 gigabits per second.
Designed to be used for multi-mode 4G/5G mobile broadband, as well as fixed wireless broadband devices, the Snapdragon X50 5G modem can be paired with a Qualcomm® Snapdragon™ processor with an integrated Gigabit LTE modem and interwork cohesively via dual-connectivity. Gigabit LTE will become an essential pillar for the 5G mobile experience, as it can provide a wide coverage layer for nascent 5G networks."
Ratification of an official “5G” standard has not taken place, but Qualcomm hopes to position itself at the forefront of its development. The mmWave technology (which is explained in this video) is only one part of the puzzle:
"Work has begun on defining, standardizing and designing the new OFDM-based 5G New Radio (NR) as part of the global 3GPP standard. 5G NR is being designed to support a wide variation of device-types, services and deployments. It is also being designed to get the most out of every bit of spectrum across a wide array of available spectrum bands and regulatory paradigms."
(More information is available on Qualcomm's 5G Technologies page.)
The Snapdragon X50 modem is set to begin sampling to OEMs in the second half of 2017, with the first half of 2018 projected for the first commercial products featuring the new modem.
