Intelligent Transportation Systems - City of Oakland

6.7.2 Medium-Term Communications Plan (5 to 10 years)
In the medium term, a ring topology backbone should be developed around the Oakland
CBD connecting all major downtown facilities such as the EOC, TMC and PAB. This
C2C backbone, which may build on the existing downtown fiber loop, will create a highspeed
connection to all City agencies and also creates an opportunity for field
communication hubs to connect to remote locations that reach the hubs through TWP
and other low-bandwidth mediums. The backbone will be developed based on the
recommendations of the detailed Communications Study performed in the near-term
phase.
The T-1 leased line between the MSY field hub and the Oakland TMC should be
discontinued and replaced by a permanent City-owned connection. The new connection
will utilize the existing microwave link between 8201 Edgewater and the PAB downtown.
This link will need to be upgraded to a higher bandwidth microwave link and a new fiber
connection will need to be established between the MSY and the 8201 Edgewater
building. From the PAB building, the existing fiber connection to the TMC could be
utilized. However, since the Transportation Services Division will only be allocated two
fibers from this connection, the City will need to either invest in one of the
communications backbone technologies discussed in Section 6.4.1 or install a larger
fiber cable in the existing conduit to complete the TMC to MSY connection.
In addition, a C2C link should be established between the Oakland TMC and the Port of
Oakland to enable sharing of data and video images. This could be accomplished by
extended the fiber along Hegenberger to the Port of Oakland TMC located at the
Oakland Airport.
Other medium-term projects should include an extension of conduits along the major
corridors and installation of fiber instead of TWP whenever possible.
Public/Private partnerships should be utilized to build additional infrastructure on the
citywide network. An example of this type of partnership is the agreement currently
being discussed between the City of Oakland and Comcast.
Medium-term projects should also include wireless interconnect to remote locations of
traffic signal controller cabinets. This wireless connection could utilize SSR or a leased
wireless service.
A schematic diagram of the medium-term proposed communications network is depicted
in Figure 6.3.
