EXPERIENCED RF ENGINEERING
OF WIRELESS INTO BUILDINGS
BY KRISTEN BECKMAN
ireless network deployments are following an
evolutionary path that started with macro external networks and are now focusing increasingly
on small cell and indoor networks, which are a
natural extension of cellular systems.
"All small cells are to the carrier are just a denser network,"
said Mark Chapman, head of corporate strategic development
at RF engineering firm MobileNet Services Inc. "Carriers
have been densifying their network for a long time.
"Originally cellular started out as a few cells on very big
hills covering large areas," said Chapman. "Initially coverage
was the key driving factor. As capacity demand increased,
those cells got smaller in height and more spread out. We've
been splitting cells and making them cover smaller areas ever
since. To some degree, 'small cells' as currently defined are just
a logical extension of that network architecture."

In-building small cells and DAS systems represent a special
case but still share many of the attributes of macro networks
and require equally careful planning and design. As such, RF
engineering firms with deep experience in the macro wireless
environment are a natural fit to help building owners bring
Rick Grant founded MobileNet Services Inc. in 2002 primarily to perform competitive benchmarking as a preferred
vendor working through carriers and original equipment
manufacturers. The company eventually evolved into network
optimization services for carriers that were deploying UMTS
and then LTE sites across the country, and now is also focusing on small cells and in-building systems as part of an
industrywide shift that Grant says has been underway for the
past two years.
"We'd already been involved in big stadiums and large DAS
