3. Mobile Networks in Enterprise
› Bring your own device
– Security: private devices
connected via Internet
› Workforce
– Mobility: access company’s
information from anywhere via
Internet
› Partners/Suppliers
– Share: partners accessing
company’s information via Internet

Indoor solutions
do not meet future
demand
Today’s solutions are
built mainly for
coverage and voice
Lack of
deployment
flexibility
Not cost efficient to
cover majority of
building sizes
Limited scalability
Costly to add
capacity, frequency
and new technology
e.g. LTE, MIMO

Medium to Large Buildings
Subtending nearby RBS
DU and IRU centrally co-located
with star configuration to Radio
Dots
DU baseband resources shared
with nearby rooftop RBS or wall
mount mRBS
Common configuration for single
tenant enterprise buildings
Enables advanced LTE
coordination between outdoor
and indoor coverage
Large to Very Large Buildings
DU centrally located in the
building
IRU distributed to floor or building
segment level

Campus or Large Venues
Multiple installations cover multiple
buildings or a large venue (university,
enterprise campus, stadium)
Centralized DU baseband can be
shared among facilities, supporting
expansions over time
