The advancements in cellular
services that have been witnessed
in recent years have had a dramatic
effect on the decision-making processes
of many field organizations within
the utilities industry. Current emergency
voice systems, primarily based on land
mobile radio (LMR), are reaching or have
exceeded their traditionally long life
cycle. The cost of replacement or upgrade
is enormous, considering the scale of the
systems and the cost of replacing mobile
and dispatch units in the field. Even the
greatest advancements in LMR, from
trunking to digital IP voice and data systems,
are no match for the advancements
witnessed in cellular. From critical voice
to the emergence of mobile data, large
enterprises, such as utilities, are finding
themselves in need of more than LMR
– yet they are culturally attached to it.

Some of the key questions coming out
of the utilities industry today are, “Where
does cellular fit within my long-term strategy?” and “What do I do about the
near term requirements for emergency
voice services?”

The Growing Criticality of Cellular

Utilities are finding that they have
a growing dependence on cellular
services.

  • The widespread use of cellular for noncritical
    applications has subtly become
    critical as people and process become
    more integrated;
  • Anytime, anywhere access to key
    resources and decision makers is
    already critical;
  • Service technician “call ahead” supports
    customer satisfaction objectives
    and workforce efficiencies;
  • The use of mobile data dispatch will
    dramatically increase the criticality
    of cellular; and
  • The increase in real-time data value,
    from scheduling changes to emergency
    response, is raising the bar on data
    communication criticality.

The Workforce Mobility Effect – A Catalyst for Change

The nature of field communications
is clearly changing with mobile data.
The adoption of mobile computing,
changing from clipboard to computer,
is enabling more efficient execution
and accounting of workforce activities,
resulting in real business improvements.
A key to realizing these improvements
is the real or near-real-time data communications
between the dispatch and
field crew applications. For this discussion,
the term “near-real-time” describes
data synchronization between field and
dispatch within a one- or two-hour window.
These applications can (but don’t
have to) communicate real-time changes
in priority, crew location information, and
routing and mapping. These “everyday”
processes are even more critical when
widespread service disruption occurs.
The vast majority of utilities that have
moved toward workforce mobility have
done so by relying heavily on cellular
carrier networks.

As the workforce moves toward a communications
model that includes data
as a key aspect, utilities are also facing
increasing communications costs and a
new dependence on cellular providers.

Radio System Challenges and Drivers

As the dependence on cellular increases,
the traditional radio systems are seeing
fewer and fewer users during normal
operating hours. Some key issues confronting large-scale field force operations
with respect to field communications are:

  • LMR upgrade or replacement costs are
    simply out of reach for systems that can
    span 10 to 20,000 square miles;
  • Spectrum availability and suitability limits
    the ability to harmonize the network
    using a common platform;
  • Land mobile radio OEMs have consolidated
    or left the business leaving
    typically a choice between one or two
    vendors; and
  • The user base is shrinking as utilities
    outsource construction and other field
    services.

LMR upgrade and replacement activity is
tempered by the realization that even the
best LMR today will provide much slower
data speeds than what is currently available
throughout much of their service territories
from cellular providers. Additionally
it will require a minimum capacity for
emergency response that will be significantly
underutilized during normal operations.
Furthermore the ecosystem that
supports field operations will extend well
beyond the enterprise and into the partner
community. Providing mobile radio and/or
mobile data equipment to that community
becomes an even greater challenge.

The shift from voice to data services is
also driving down capacity requirements,
but not scale, resulting in significantly less
voice traffic. Many utilities have already
shifted noncritical voice communications
to carriers and have adopted carrier-provided
mobile data services.

Tactical vs. Strategic Response

Utilities are being forced to confront
a very basic question in regard to
field communications: “Will my response
to an aging infrastructure be tactical
and focus on current like kind, or will the
investment align with a broader strategy
that includes everything from electronic
meter reading to asset monitoring and
intelligent grid initiatives?”

The Tactical Response

The tactical response leads down a narrow
path. For example:

  • Fewer and fewer vendors offer land
    mobile radio equipment;
  • Spectrum availability limits common
    system architectures;
  • Transition from analog to digital
    requires a new network design, coverage
    analysis, site requirements and a
    likelihood of additional sites; and
  • Minimum capacity requirements for
    emergency response will result in significant
    underutilization during normal
    operations as more field workers use
    cellular as their primary means of communicating.

The fact is that utilities must have communications
during critical moments
throughout the day. Safety is critical. A
renewed investment into reliable communications
is inevitable; your crew’s life may
depend on it. But in many cases, real analysis
needs to be done before you invest;
you need to know what you are getting
and not getting; and you often need a
new strategic approach to maximizing the
value of the investment.

The Strategic Response

Utilities that have a strategic response
take a structured view of current systems,
assets and capabilities as well as current
and future field requirements.

Some of the key strategic challenges
are:

  • How do we create the most business
    value for the least cost?
  • How do we leverage as few solutions
    as possible to enable business requirements?
  • Does a single solution provide the best
    solution?
  • Does the solution provide for future
    communication requirements?

The Optimal Comparative Communications
Architecture Methodology (OCCAM),
a methodology created by IBM, provides
a structured approach to building design
templates and business case templates
for studying the optimal communications
architecture for a given environment
and business need. This architecture is
based on matching the most appropriate
communication technology with a given
geographic area and business need. The
OCCAM approach is broken down into the
following phases:

  • Phase 1: Technology Identification
    – During the technology identification
    phase, the study will focus on identifying
    relevant communications technologies,
    understanding each technology’s
    strengths and weaknesses, and documenting
    the high-level costs associated
    with each technology.
  • Phase 2: Environment Stratification
    – During the environment stratification
    phase, the study will focus on identifying
    the attributes that make up a unique
    environment. These environments
    should be general enough to be replicated
    in multiple geographic locations
    through the utility service territory but
    specific enough so as to best meet the
    financial and business needs for a
    given area.
  • Phase 3: Design & Business Case
    Template Development – During the
    design & business case template development
    phase, the study will leverage
    the information gathered during the
    previous phases to develop architectural
    design templates and business
    case templates for each of the unique
    environments identified within the
    utility’s service territory.

Conclusion

In applying the OCCAM principles to several
utilities that are in need of investing
in aging field radio systems, a case can
be made for shifting to a cellular-servicebased
model. In order for utilities to realize
the benefits of this model, investment
and cooperation will be vital.

Collaboration between cellular carriers
and utilities have the potential to drive
significant improvement in carrier networks
and create unlikely investments in
carrier infrastructures from enterprises
that can spend less to invest in hardening
cellular sites and establishing priority,
coverage and availability requirements,
than investing in a wholesale replacement
of their existing LMR environment. In addition,
as carriers advance, whether through
licensed WIMAX or future 4G technologies,
collaboration will allow both carrier
and utility to better understand the needs
and capabilities of each other. In this
increasingly globally integrated world, the
integration of interests between cellular
service providers and large-scale mobile
workforces has the potential to benefit
much more than just the carriers and
the workforces. Improvements in backup
power facilities, in cooperative priority
restoration services, and coverage
enhancements that reach every power
meter, would translate into greater coverage
and availability for us all.

Regardless of the final outcome, utilities
must have a plan for the future that meets
the field requirements of today
and tomorrow.

Utilities Should:

  • Develop a comprehensive communication
    road map defined by business
    goals;
  • Develop detailed communications
    requirements for achieving business
    goals;
  • Collaborate with those that have intersecting
    interests; and
  • Develop a clear path to closing the gap
    between current state and future state.

Utilities Should Not:

  • Always wait for something better;
  • Ignore obsolescence and an aging infrastructure;
  • Develop technology road maps that fail
    to map to business goals; and
  • Fail to collaborate within their business
    ecosystem.

In IBM’s quest to drive innovation that
matters, we often encounter the effects of
culture and tradition. Moving beyond that
is the most difficult step a utility will make.
It is also potentially the most beneficial.
