SAN Objectives
•SAN objective is development and validation of LTE/LTE-
Advanced based mobile Ad-Hoc/Mesh network.

T
he main
g
oal is to offer alternative
p
ath of radio communication
gp
in addition to the existing communication networks.
•This solution is designated for areas without or with poor radio
coverage conditions (which may be caused by disaster or hostile
military actions) by deployed communication networks.
•SAN will enhance of the LTE/LTE-Advanced solutions by
incorporating a rich set of relaying/meshing capabilities

capabilities,
2.RS is an LTE node equipped with Relay/Mesh capabilities, and can be fixed or

3.UE is an LTE User Equipment without ad-hoc Relay/Mesh capabilities
Each node can operate as a UE or eNB in the regular LTE networks, or
simultaneously in the SAN and regular LTE networks.

normal operation through LTE network,
•Any node is endowed with Relaying or meshing capabilities and is
capable to route or switch through the traffic of other nodes when
direct point to point communication is not possible.
