Dear all,

In the BoF draft agenda, we’ve included several presentations from the baseline technology providers. The goal of these presentations is to bring more light on their constraints, particularities, commonalities and differences. The presenters will have no more than 10 minutes for the talks, which should not be marketing talks. 

Together with Suresh and Pascal, we’ve identified a list of several points we’d like to see in these presentations. If you see some other points you’d like to see addressed, please speak up. We will be working with the presenters to make sure that we have a balanced overview of all baseline techs.

As a reminder, we have the confirmation of the following speakers for the BoF:
- Technology slot 1: 3GPP LPWA (NB-IoT / EC-GSM-IoT / Cat-M1) - (possibly Antti Ratilainen, speaker to be confirmed)
- Technology slot 2: IEEE LPWA (Wi-SUN, IEEE 802.15.4g) - Bob Heile (confirmed)
- Technology slot 3: LoRa - (possibly Alper Yegin, speaker to be confirmed)
- Technology slot 4: SIGFOX - Juan Carlos Zuniga (confirmed)

Best,
Alexander

0) NETWORK DEPLOYMENT + TARGET APPS
- Current deployment map
- Predicted coverage, number of devices
- Example application + hw configuration
  - Device classes 
  - Low-end app (minimal MCU/RAM/radio config/data profile) + High-end app (expected CPU/RAM/radio config/data profile)
