STAFF REPORT
On July 12, 1990, Marlarid Howard, Director of Communications
with the County of San Bernardino, met with City staff to
answer our questions on 800 MHz. After talkinq to Mr.
Howard, it has ~0118 very clear to me, that the City of San
Bernardino should implement its own 800 MHz system. Under
the County operated srstem, the City would have nO control
over decisions relat nq to system operation. The other
factOr is the cost of a City system versus a County system.
Attached is a cost breakdown prepared by Dick McGreevy.
Mr. Howard has explained that if the City'S decision is .to qo
on its own, it will in no way. have a detrimental effect on
our relationship with the County. B8cau.. all public
aqenc:ies within. the County of San Bernardino will be using
the same equipment, Motorola, and the same- frequencies, 800
MHz, there will be no impediments to reqional communication.
Implementation of our own system can be a siqnificant
advantaqe to reqional cooperation, as the City can provide
backup support in the event of failure on the par~ of the
County transmission capabilities. I stronqly believe we
should indicate to the County that we are movinq forward with
our own system.
As the implementation of the 800 MHz system is a siqnificant
policy issue in two areas: cost and control, I have
scheduled a luncheon workshop for Auqust 6, 1990 in the MIC.
Mr. Marland Howard will be present to answer questions.
Please read the attached report from the City's consultant,
OMNICOM.

Anaryala of 800 MHz Radio ',stem '"ue. for the
City of San BernardIno
The City of San Bernardino must make a decision of whether to Implement its own 800
MHztrunked radio system or join in the County 800 MHz radio system.
The major I8sues Involved In this analysis of this decision are:
. Costl and Control
. Channel Availability
. Compatibility
. Communications Backup
.
The current rate for access to the County Radio Backbone system Is $25 per radio
per month Jarever. This rate has been revised twice, having started at $105 per
radio per month, then $61.05 per month In late 1989, and Is now $25 per radio per
month.
By c:;omparison, the cost calculated for the City of San Bernardino system Single
,ite backbone system based upon Motorola cost information 18 $13.58 per radio
per month for .10 vears, or $8.79 per radio per month for 20 vears.
(Note: The backbone maintenance and management costs of $3.30 per radio per
month wiD continue forever.)
The County &Ceess fee has additional costs that have not yet been determined.
Among these 18 the system Administrative Services cost. which Is listed as "rates
to be determined" In the County" voice radio system rate schedule.

In acldltIon,lf the City requires more talk groups (Note: In a trunklng system, talk
groups ...1 Iyrlonymous with channels), each additional talk groLfp will cost an
8dcIltIon8I$10"per radio per month forever. The City of San Bernardino will have
very lUte control over talk group allocation. The Operations Committee will be
"Instrumental" In determining the number of talk groups and they will "recommend"
talk group assignments to County System Administration.
Therefor., the City of San Bernardino has one voice on a committee that is
",*rumenta/" In making a "recommendation" that mayor may not be approved.
The bottom line 18 that If the San Bernardlno Ponce Department and Fir.
Department each require two more talk grOUpe than they are allocated (which is
a plausible scenario), the access charge would Increase by $40 (4 talk groups X
$10) per radio per month ,orever. This would bring the County access fee up to
the $60 per radio per month area.
An additional unknown factor that affects the COunty system access rate Is the
planned review of the rat. structure after two y..... of operation, which will result
In a. . . "rate adjustment as appropriate".
e
The FCC allocate. 800 MHz channels based upon the number of radio units In a
systlm (one channel for every 100 units). This ratio has been somewhat
compr...ed In San Bernardino County because the fun channel allocation has not
yet been realized. However, the City has a longstanding verbal understanding with
the County that the City of San Bernardino wllllnltJally require 8 channels for Its
Independent communications system. this requlr.ment was originally presented
in the County of San Bernardino Preliminary Working Plan dated 1986. These
channels are currently available In the system since the County has offered to
Include the City', 830 radio units In the County system.

If the City Implements Its 800 MHz system, It will be able to opElf'ate on the same
talk gtoupl end on all of the tame frequencies as the County system. Further, this
separate, duplicate capability of the City lYSltmean be a 8lgnlfica~ advantage to
the RegIonal concept, should . catastrophio failure on the part of the County
backbOne ..rvInQ the East End ocx:ur.
.~
Nt lncIependent City 800 MHz racllo system would be completely eompatible with
the County 800 Mhz radio 'ystem.
The City proPos" to use the same equipment venc:lor (Motorola) and the same
~s protocol as the County system is using. The acc;..s and use of the data,
mutual aid and alr.to.ground channels win be c:ompIetely compatible with the
County eystem.
Because the City channels will be licensed and operated separately from the
County', operation, all compatibility Issue. are resolved by the procurement of
Identlcal radios from Motorola, the vendor selected by the County. And because
the radlo8 wID be identical, the integrity of the Reglonel communleatlons system is
maintained.
.
The CIty'. communications system can provide backup communications capability
to the County radio system and County Communleatlons Center In the East End
of the valley Just as the West End system can provide backup capability In the
West End of the vaney. This capability I. possible without any equipment
modifications because the equipment for an three systems (County, West End and
San Bernardino) Is from the same vendor (Motorola).

In addition, the City's Communications Center COUld operate as a County backup
with the 0Ip1blllty to control both systeme through the use of COntrol stations in
the event d lyItem failure..
.
The City', Communlcatlon8 Center 111180.8-1.1 center, which further Increases
Ita value as . backup Public Safety Communleationa Center for the County in the
East valley area. The City', Public Safety 8-1.1 center presently has a backup
agreement with the County Sherltf, CommunIcatJont Center whereby City and/or
County 8-1-1 Unl. can be switched to either Communlcatlona Center In the evenl
d . failure of the other Center.
Therefore, If the City joins the County system, the Issua are:
,. City hat little or no control over the County IYstem operation or costs. The
City', role would be advisory only.
2. The system comparative cost analysis Is currenUy Incomplete because
some County cost Items have not yet been determined and other cost
Items have a high probabHlty of Increasing. The bottom line Is that a City-
owned and operated system would be less costly, probably by a very large
margin.
If the County's acc... fee begins to approach the recent Ilgure of
approxJmattly $80 per radio per month, the City of San Bernardino could
totally fund their own backbone system for less than 2 year's access fees.

3. If the City jolna the County system, there will be no backup radio system or
bIckup Communication Center in the East valley. If the County system fails
during en earthquake, for example, the City of San Bernardino could
provide backup in the form of a radio system and a Communications
Center. Thiels also true In the West va/ley area where the West End JPA
communlc8tlon system and the County system back each other up.
4. The City has a longstanding understanding with the County for 8 channels.
With regard to channel availability, since the County has 8 channels In the
County system to assimilate the City of San Bernardino, then these
channels may logically be made available to the City for Its use In
Implementing their own system.

, just received a significant bit of information from Ben
Nunnally, the local area manager for Motorola, which I
believe the Common Council should know. Mr. Nunnally says
that Motorola's contract with the County does og1 auarantee
95 percent probability of coverage in buildings in the City
of San Bernardino. Mr. Nunnally said that Motorola would
guarantee that coverage in dense buildings in San Bernardino
if the transmitter site was Little Mountain' rather than the
County sites of Jurupa Hills and Sunset Hill.
