Cellular LPWA – Terminology Primer
A Terminology Headache?
• LTE-M, LTE-MTC: ”Long Term Evolution” / “Machine-Type Communications”
Continuous stream of improvements to the cellular technology to address massive IoT
Examples: Low Access Priority (for M2M devices), Power Saving Mode, Extended DRX, Extended Coverage…
• Cat-3, Cat-1, Cat-0, Cat-M, Cat-M1, Cat-M2: The LTE Device “Category”
Indication of a device’s maximum speed (and thus complexity, and thus cost)
Examples: Cat-3 = 100Mbps (DL); Cat-1 = 10Mbps(DL); Cat-0 = 1Mbps(DL); Cat-M(1) = 375kbps (UL)
• EC-GSM, EC-EGPRS, EC-GSM-IoT, NB-LTE, NB-M2M, NB-OFDMA, NB-CIoT, C-UNB
The various 2G and 4G-LTE technologies evaluated by 3GPP
The name of the resulting long-term 4G consensus is “NB-IoT”; for 2G it will be EC-GSM-IoT

Cellular LPWA – The key take-away
The important thing to remember
Chips may well combine two or several technologies
They will be sold in 2017 on today’s 2G and 4G networks with the needed
Ultra Low Power Deep Coverage Low Complexity

13. Proprietary and Confidential 13
Focus on PSM – Power Saving Mode

Power Saving Mode (useful for outgoing data)
Lets the modem “hibernate” between data transmissions while
remembering its network state (no need to re-register)
Power consumption in hibernation: 4 μA
Gain on battery lifetime: x2 (compared to shutting modem off)
Ex: Tx 670 bytes / Rx 350 bytes on 2500mAh AA battery
1 transmission every 1 hour
1 transmission every 6 hours
1 transmission every 24 hours
=> 1 year battery life
=> 5 years battery life
=> 19 years battery life
With Power Saving Mode
Without Power Saving Mode (coming from “OFF”)

Focus on EDRX – Extended Discontinuous Reception
Extended Discontinuous Reception (useful for incoming data)
Lets the modem listen more infrequently for incoming data
Maximum “listen interval” so far: every 2,57 seconds
Now the listen interval can be up to 52 minutes
1 listening every 1 minute
1 listening every 5 minutes
1 listening every 15 minutes
=> battery life x23
=> battery life x116
=> battery life x350

Frequently asked questions
• What is it that we have in the demo at Mobile World Congress 2016?
It is an LTE-M, Category 1 module, the world’s first with the following 3GPP release 13 features:
“Power Saving Mode” and “Extended Discontinuous Reception” (both power optimization features)
• Is it a Cat-M (Category-M) or Cat-M1 module?
No. Cat-M(1) chipsets don’t event exist yet. It is an LTE-M (or LTE-MTC) module, Category Cat-1.
The Category (M1) is an indication of the module complexity, cost and speed.
“LTE-M” refers to a set of LTE features (like PSM or eDRX) optimizing LTE for the Internet of Things.
• Is this module available for sale?
Not yet, as we want to make it even better. But we will run trials this year with selected partners.
Commercial availability of LTE-M modules from Sierra is scheduled for early 2017.
• So you have LTE-M modules, ok. What about NB-IoT modules?
NB-IoT is another 4G technology for IoT, with other optimization choices.
The standard is being finalized right now, and eventually Sierra will of course offer NB-IoT modules.
What you may hear about others demoing NB-IoT at MWC2016 is a non-standard version of NB-IoT.
• What are the advantages of LTE-M modules compared to regular LTE modules?
Ultra Low Power, Deep Coverage and Reduced Complexity
