Join
Nodes initiate JOIN
blindly even GW is out
of range, which
causes interference to
other irrelevant GWs
and their nodes Nodes initiate JOIN

irrelevant GWs and
their nodes
1. NetID is broadcast
by GW.
2. Nodes only initial
the JOIN procedure
after catching NetID.
Roam
ing
NetID is only known
after JOIN, It is left for
users to define how to
use NetID to achieve
Roaming
Roaming is not sup-
ported NetID identified by
Nodes among clus-
tered GWs.
Multi
cast Multicast is not
defined
Multicast is not defined
Support
1. GW can do multicast
by assigning the packet
of a multicast network
address
2. Encrypt it using a
multicast key.

Aloha:
Sending packets by
node control may
cause collision
between packets Aloha:
Sending packets by
node control may cause
collision between pack-
ets TDMA:
GW send SPS through
beacon and the node’s
transmission time is
dependent on it.
QoS
LoRaWAN defines
confirmed data, which
allows either GW or
Nodes to retransmit
data if it is not Acked WISE-Link 1.0 defines
confirmed data, which
allows Nodes to
retransmit data if it is
not Acked
Guaranteed to send
data without collision
periodically by SPS
cycle.
Security
Key
lifetime
Once Nodes com-
pleted JOIN, the life-
time of session keys
are permanent
Nodes are requested to
do periodical JOIN,
thus session keys can
be refreshed on each
