DEPLOYMENT STRATEGIES

Parallel Wireless, Inc. Proprietary

GAINS WITH CLOUD-NATIVE APPLICATIONS

DEPLOYMENT CHECKLIST

With Parallel Wireless OpenRAN, deploying or expanding networks is much simpler

!
!

Site

Acquisition

High cost to build new
towers

Equipment

Higher cost, longer
deployment times with
legacy RAN

Installation

Special installers on site

Requires site visits which
increases OPEX

Maintenance

Lowest TCO

Does not require expensive
towers, OpenRAN can be installed
ANYWHERE

Interoperable OpenRAN approach
enables vendor diversity and cost
reduction

Self-configuration and selfoptimization with OpenRAN
Controller and Business Intelligence
(SON) module

Increases the cost to the
end-user, takes longer to deploy

Backhaul

Demands on transport

Automated for lower OPEX

Flexible and future proof backhaul
including satellite and microwave
removes the expense and
complexity of fiber backhaul

Enable coverage fast and
cost-effectively!

UPGRADE/DOWNGRADE OPEN RAN WITH CLOUD NATIVE

Canary release is a technique to
reduce the risk of introducing a new
software version in production by
slowly rolling out the change to a
small subset of users before rolling it
out to the entire infrastructure and
making it available to everybody.
