A fascinating dialog is value remark. I feel that it is best to compose more on this matter, it may not be an unthinkable theme however generally people are insufficient to chat on such subjects. voyance gratuite en direct sans attente To the following. Salud.

I just clear
Well, I have check different website on the 3GP support while surfing the internet but your content is just informative.

Re: Seems like a pivot
Interesting how "We'll have a product this year but I don't think there will be anything to connect," at least not until 2017 they say. But, nonetheless something watch at IoT activity starts ramping up over the coming years.

Re: Seems like a pivot
Complexity and low energy usage do not go well together... most of the power consumption of LTE Mx still comes from complex synchronization with the network requiring sniff periods ... and energy.  The success of the design of LoRaWAN perhaps means that the members of the LoRa alliance have found the right complexity balance to fit requirements and constraints of LPWAN.

When extending ThingPark Wireless, Actility will provide full MVNE subsystem for LTE-Mx optimized for millions of parallel sessions with few packets/day each, and sharing OSS/BSS with existing LoRaWAN ThingPark wireless. That will allow telecom operators to easily extend their LPWA offering to LTE Mx. It may be surprising, but the main issue of cellular operators for LTE Mx roll-out is not in the RAN, but in the OSS/BSS. It is very hard to get attention and time of your internal IT when competing for resources against high ARPU projects like the next iPhone ! That's why we believe from organizational point of view, it is way simpler to consider LTE-Mx as an internal MVNO, which requires a fully autonomous MVNE susbsystem.

Regarding multicast firmware upgrade, this is supported at the application layer and how to do it is available to LoRa alliance members. it is based on adding redundancy to the multicast data (typically a firmware patch), then multicast it over the network using class C or class B. It does indeed require downlink capacity shared with the rest of the network, as any other technology. This downlink capacity may be throttled to use only a fraction of total capacity : i.e. upgrades do take time (a small patch may be done in a day, but others will require multiple days). LTE-M, for obvious reasons, does not have that type of limitation, so if immediate or unicast upgrade is a must over the WAN, LTE M is the way to go. We have also seen some use cases use bluetooth for upgrades.

Re: Seems like a pivot
It has been surprising the adoption that LoRaWAN has seen, given that it is a fairly unsophisticated prototcol compared to LTE-M1/2. I disagree with your statement that LoRaWAN is capable of streaming multicast firmware updates over the air, without effectively bringing down the network. Unless you're referring to Symphony Link, a different protocol for LoRa, which I don't think Actility supports.

What is Acitlity's value add to LTE-M1, since the carrier is providing connectivity that is essentially "the internet." Is it just device management?

Re: Seems like a pivot
Actually we view LTE-M1&M2 (aka nb-IoT) , and LoRaWAN, as complementary technologies for the LPWA market. ThingPark creates a similar user experience and APIs for both types of networks. See our webinar on positioning of the two technologies on www.actility.com --> LoRa® positioning vs 3GPP technologies

In short, for 20 frames/day, you still have a ~5 fold difference in energy consumption in favor of LoRaWAN, and also an order magnitude difference in peak current that becomes important for battery chemistries used for 15yr+ operation. We believe LoRa will become the "Wifi of IoT" in dense deployments and campus/regional, but also continue to be a first choice for all applications that require very long battery life and low cost. LTE-Mx will rule for applications that need voice (e.g. alarms with voice call option), rapid unicast firmware updates (LoRa can do streamed multicast updates), or large payloads. Ultimately the market needs both, but that does not mean you need separate OSS/BSS and APIs.

Seems like a pivot
Seems like Actility is being forced to pivot away from Lorawan. Not suprising given that 3GPP based technology will address the reliability and performance issues of LoRaWAN, in licensed spectrum, at a competitve price. 

Lora is a better technology for application specific / private networks. It does very well in that space.
