## 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.
