The document outlines MobiMESH technology, which includes a wireless multihop backbone network and access points that allow Wi-Fi clients to connect. The backbone uses a radio-aware routing protocol to avoid interference. Mobility management allows clients to seamlessly roam between access points. The network is configured and managed centrally using a management system.

3. MobiMESH Network Architecture
• Backbone:
wireless
multihop
infrastructure
• Access:
appears as a
WLAN to clients
• Wired
Backbone
integration

4. Access Network
• Any Wi-Fi (IEEE 802.11) client can access the network
• The Access Network is perceived by clients as a standard
Wi-Fi network
• The Access network can work in the 2.4 Ghz, 4.9 Ghz and
5 Ghz frequency band, at admin's choice

5. Access Network (2)
• All security protocols for access networks are supported:
– WEP
– WPA/WPA2 (PSK, EAP-TLS, EAP-TTLS, EAP-PEAP...)
– MAC ACL
– VPN
• RADIUS integration for Authentication, Authorization and
Accounting (AAA)
• Captive Portal support for Hot-Spots

6. MobiMESH Backbone
• MobiMESH Backbone constitutes the wireless distribution
system
• Multi-radio, Multi-hop network
• A real, layer 3 network
• Main tasks:
– Transport access traffic
– Signalling
– Mobility Management
• Radio-Aware Routing Protocol

7. MobiMESH Radio-Aware Routing Protocol
• Protocol Features:
– Multi-channel: interference aware
– Aware of the physical rate of the link
• The Idea: Avoid using the same frequency in and out the
same node
• More interfaces (and frequencies) on a node -> less
interference
• Most producers (Cisco, Tropos, …) still developing it!!

8. Single Radio Vs Multi Radio
• Single Interface: half duplex link, low throughput
• Multiple interfaces: contemporary transmission and
reception, high throughput

9. Real Mesh Vs Bridged Networks
REAL MESH BRIDGED NETWORKS
• Layer 3 • Layer 2
• Routing protocol: • Single IP network:
– Optimization – No routing, only
mechanisms broadcasting
– Failure recovery – Bandwidth loss
• More Scalable – Manual and slow failure
recovery (if any)
• Easy management

10. MobiMESH Backbone Security
• Router Authentication
– MobiMESH Routers are authenticated through digital
certificates
– No attacker node can enter the Backbone Network
• Traffic Encryption
– Both data traffic and signalling is encrypted
– Ciphering with time-changing key

11. MobiMESH Mobility Management
• Access terminals are tracked and their position is known to
the Backbone network
• Once a terminal changes access point, traffic is routed to
the new location
• Active connections are not lost!
– Max Handover time is
around 100ms
– Best performance on the
market!

12. MobiMESH Management System
• The MobiMESH Network is managed
through the MobiMESH Management
System (MMMS)
• Main tasks:
– Network configuration
– Configuration provisioning
– Network management
– Network monitoring

13. MMMS: Network Configuration
• Every parameter on the node can
be configured on the MMMS
• Every wireless interface can be
configured as a backbone or as
an access interface
• Every interface can work on both
2.4 GHz and 5GHz frequencies

14. MMMS: Configuration Provisioning
• The MobiMESH network is self configuring
• It automatically creates the desired configuration
• When a node is powered on:
– It tries to find the MobiMESH network
– It contacts the MMMS and it retrieves its configuration
– It applies the configuration
– It joins the network

15. MMMS: Network Management and Monitoring
• The Network can be managed and monitored through the
integrated map
• Some administration tools are provided:
– Backbone Link Status
– Connected Clients list
– SNMP Echo test
– SSH Console
– Watchdog
– Node Recovery Mode

16. MobiMESH Installation
• MobiMESH Installation is an easy
task
• When the node is placed on the
poles, the Positioning
Interface helps pointing
antennas

17. MobiMESH Installation (2)
• Once MobiMESH Routers are
installed and powered on, the
network comes up
automatically
• If any configuration mistake has
been made, the watchdog
rescues the node: no need of
on-site intervention
• Remote management
