times out of PSM.
LTE Cat-M1
Key Takeaways
8. Got Questions? Ask at forum.link-labs.com
• How is this different?
• Cat- NB1
• 200 kHz
• Max 144 kbps uplink
• Half Duplex
• Chipsets could be slightly less than LTE-M1
Technology Snapshot NB-IOT
9. Got Questions? Ask at forum.link-labs.com
• If LTE-M is “LTE-Light,” then NB-IOT is LPWA on steroids.
• Appropriate for sending “sensor messages” but not data streams.
• Deployments in 2018. US may lag significantly.
• Modules <$15?, Service costs?
• Market perception about advantages over LTE Cat-M1 (Power, cost,
coverage) do not hold.
