900 MHz is ideally suited for the size towns and
cities we have in the upper Midwest, but many agencies want to
better understand why 900 MHz is a better public safety solution
than cellular. Here are some things to consider:
You can own,
operate and manage your 900 MHz network and not be at the
mercy of a third party, non-public safety entity when problems
occur.
The cellular network is used
by the general public, including residents of your town,
travelers on highways and interstates, and visitors at
conventions and sporting events, and they are now being
routinely used by the younger generations to download large
video and music files. These uses are increasing
congestion on the commercial networks.
There is less security on
cellular networks. Maintaining VPNs and session
persistence has been a problem
Your local cellular provider
probably has to trunk to another regional center to make
your system work, thus increasing your vulnerability.
What are the points of
failure of the commercial service network? Will your
carrier provide you with detailed network diagrams
identifying their points of vulnerability?
When the commercial cellular
network goes down or has interruptions, you don't have the
ability to restore and reconfigure it. The rule of
thumb is that the bigger the network, the less resilient it
is under stress.
You have the ability to
contractually guarantee service response time with your
private 900 network. Will cellular carriers provide
service response time guarantees in writing?
With private systems you're
able to reduce or eliminate your dependency on external
fiber/connections. Major incidents outside your
jurisdiction won't interrupt your network.
Many cellular companies are
having extreme financial difficulty. Some acquisitions
have been failures, product lines and technologies have been
dropped and build-out/improvement schedules delayed while
the industry is trying to settle. The longevity of
solutions are doubtful.
Costs - Cellular solutions
are less capital intensive, but on-going operating costs
rise proportionally with each added user. Conversely,
additional users/departments can be added to private systems
with minimal impact on operating costs.
