Through this initiative “Unwire Pune”, Pune Municipal Corporation (P. M. C) proposes to deliver a solution to the citizens, businesses and academic institutions to enable to seamlessly connect to the internet in a relatively easy manner.As much as providing basic facilities such as drinking water supply, sewerage, power, roads etc, P.M.C would like to provide basic IT infrastructure such as stable internet connectivity to its citizens and also offer compelling business and cost models to attract and sustain major ISP businesses in Pune.
Objectives
-
To deploy a backbone wireless communication network infrastructure to the entire 400 sqkms of Pune city that can be leveraged to provide wireless networking needs of any citizen, University, or business with minimum additional investments.
-
To deploy a wireless communication network infrastructure to citizens in about 400 sqkms of select areas of greater Pune that will enable ubiquitous connectivity to the Internet.
To deploy a wireless communication network infrastructure to citizens within 100 sqkms of the metropolitan area of Pune that will enable ubiquitous connectivity to the Internet with speeds up to 128kbps per user.
-
To complete the project within 12 calendar months.
-
The primary technical objective of this project is to ensure a successful deployment of a wireless network infrastructure in Pune city that will enable ubiquitous connectivity to all the stakeholders such as citizens, businesses, and education institutions. This wireless network infrastructure will be designed and deployed using combination of WiFi and WiMAX depending upon the feasibility, product roadmaps that suit the deployment for the given time frames of implementation.
The network architecture deployed should be scaleable, cost effective and interoperable with variety of handheld mobile devices like Laptops, wireless handset, PDA and other small form factors that support standards based interfaces and software stack for mobile networks.
The WiFi tier should be fully Wi-Fi certified (the Stakeholders prefer the IEEE standard known as 802.11g). It will offer outdoor wireless coverage anywhere within the defined Coverage Areas, and should additionally provide reasonable indoor support. The Wi-Fi Tier will provide fixed, nomadic, portable, and ideally mobile service in the defined Coverage Areas.
Standards-Based: The Wi-Fi Tier will be fully Wi-Fi certified preferably based on the IEEE 802.11g standard. It will consist of sufficient standard IEEE 802.11g outdoor equipment to service outdoor users anywhere within the defined Coverage Areas. Additionally, all Wi-Fi radios deployed will be fully standards compatible and set to accept connections from IEEE 802.11b-only clients.
Backhaul: The outdoor Wi-Fi equipment will ideally be backhauled to the nearest PoP using WiMAX-based CPEs and/or wired connections, whichever is more cost effective.
Bandwidth: The IEEE 802.11g radios will accept full speed 54 Mbps wireless associations from nearby clients unless IEEE 802.11b connections to the same radio are occurring. Additionally, all Wi-Fi radios deployed must be fully standards compatible and set to accept connections from IEEE 802.11b-only clients.
Highly Available: The System will be highly available for all classes of users, supporting at least 99% uptime for the Wi-Fi Tier of the System.
Equipment: For the Wi-Fi Tier, PMC prefer the Wi-Fi standard known as 802.11g, which operates in the 2.4GHz frequency band. The WiMAX Tier will provide point-to-point and/or point-to-multipoint service to fixed locations of the city. It is expected, though not mandatory, that the WiMAX Tier will serve as backhaul for the Wi-Fi Tier, and it is preferred that it is based on industry standards such as 802.16-2005 WiMAX The System must have a robust backhaul layer that interconnects all the subscribers and nodes in the Wi-Fi Tier and back to the Point of Presence (PoP). This backhaul layer should exhibit the following characteristics:
Standards-based:It
is expected, though not mandatory, that the backhaul layer will be based on IEEE 802.16-2005 WiMAX and serve as backhaul for the Wi-Fi Tier. To achieve the desired WiMAX line-of-sight coverage, tower space to place base stations may be required in many instances. Ideally, the backhaul layer will include IEEE 802.16-2005 WiMAX as this standards-based approach will provide for highly competitive multi-sourced equipment purchases as the standard rolls out and gains in popularity.
Aggregation to PoP: Connectivity from base stations to the PoP can be achieved through wired or wireless solutions, as long as it is carefully architected to remove single points of failure.
PMC has organised a workshop for stack-holders to know their expectations from this project. For further details mail to ambarish.galinde@punecorporation.org
