Urban Mobility:Municipal Wireless Networks as an Enabling
Technology
Prof. Antonio CaponePolitecnico di MilanoAdvanced Network Technologies Laboratory
MuniWireless NetworksA new emerging application area of wireless networksTremendous interest worldwidePublic utility services as distinguishing featureLocal governments and authorities as new actors for building up infrastructures and providing services
Big cities Medium-small cities Solution to digital divide
MuniWireless ServicesDeployment of a city-wide pervasive wireless network for offering a large set
of services to public agencies, local police, fire dept, citizens, shops, local companies, and visitors.
The wireless network as a key enabler for a large set of value-added public-utility services for the
community.

Which technology for MuniWireless?
WiFi is today the only available solution able to cope with the request of open platform for public utility service development
The development of services and applications on mobile wireless networks is complex due to:
The constraints posed by mobile service operators that need to completely control service provisioning according to their classical business modelFrequency licences that prevent local government to make investments directly into the communication infrastructures
Like the history of Internet teaches us, in order to develop a large number of popular services we need:
Open platformsComplete freedom of developing of applications for third parties (wrt manufacturers and service providers)
WiFi MESH
The problem: WiFI for large scale public networks has to cope with the problem of the broadband wired infrastructure
Ethernet
Solution: Replacing wired infrastructure with wireless links
Internet
Wireless Mesh Networks
Mesh routers (MRs) manage routing automatically based on ad hoc network technologiesDevices are flexible and self-configuringAll or a subset of MRs act as access points (Wi-Fi hot spot)Some devices are the gateways to the InternetBackhauling: WiFI, Hiperlan, WiMax, BPLC ... (maybe LTE MESH in the future)

Experimental Projects in the Academic Labs
MIT RoofnetFirst experimental projectLow cost HWSoftware open-source
Other projectsGeorgiaTech BWN-MeshRice UniversityRutgers Winlab ORBITSUNY Stonybrook HyacinthMobiMESH PoliMI
Several academic projects have contributed to the commercial exploitation of the technology
MobiMESH ProjectStarted by ANTLab, Politecnico di Milano in 2004Initial goal:
Create an experimental platform for testing innovative solutions for routing, mobility management, network configuration and management
Soon coupled with the goal of:Designing advanced mesh networking solutions and products for the market
Today MobiMESH is a spin-off company of Politecnico di Milano
