4G Solution Overview 092721.pdf

OVERVIEW

Parallel Wireless’s fully virtualized, software-based unified 2G/3G/4G/5G architecture allows operators to easily deploy,
managing, scale, and future-proof their new 4G/LTE networks or cost-effectively migrate their existing networks from 2G/3G
to 4G while providing the lowest TCO by making the networks selfconfiguring, self-optimizing, and 5G-ready. Parallel
Wireless’s solution is ideally suited for:

• Greenfield 4G Deployment: SPs looking to provide new 4G service in rural or urban areas.
• Densification: SPs looking to densify their 4G networks to support increasing user count.

THE CHALLENGE

Global MNOs are facing flat or declining ARPU due to increased data consumption that strains their networks. They
need new solutions to support different use cases: to expand, densify or build new 4G networks. New greenfield
deployments require high speed rollout for coverage at the lowest possible initial cost, while fixed wireless requires
targeted high capacity in specific areas. Any densification deployments require a cost-effective strategy for configuration and for on-going optimization. It is very difficult to meet these often-conflicting requirements with traditional 4G
architecture where each topology, use case, and service type means additional cost from legacy vendors.

THE SOLUTION

Parallel Wireless’s solution is comprised of two main components to provide LTE based functionality. The Open RAN RRH
hardware from a variety of ecosystem partners. A COTS vBBU can provide shared capacity or enable Carrier Aggregation
(CA) at a much lower cost.

Open RAN Controller software suite consolidates all necessary functionalities to build, expand or densify the 4G RAN (i.e.
X2-gateway, small cell gateway, security gateway and SON) to build new or expand/densify current 4G networks.

The software acts as an aggregator toward the core network (EPC), while orchestrating the RAN. Parallel Wireless Open
RAN software suite will help reduce network complexity while improving performance and efficiency. It also provides an
easy path towards overall 5G network migration. When operators expand or densify their networks with Parallel Wireless’s
solution, the abstraction layer will reduce signaling towards the core, which means there is no need for additional capacity
from an existing EPC vendor thereby reducing the CAPEX. In addition, the signaling from all the RANs in the densification
layer will be absorbed by the Open-RAN software abstraction layer. Parallel Wireless’s Automation and Orchestration
software module provides SON functionality to enable self-configuration and self-optimization during deployments,
resulting in quick and easy rollouts. Interference mitigation by OPEN RAN SOFTWARE simplifies network expansions to make
them easy to scale. OPEN RAN SOFTWARE is software-upgradable, removing the cost and complexity of transitioning
the networks to 5G.

BENEFITS TO SERVICE PROVIDERS

CLOUD-NATIVE ARCHITECTURE:

• Open RAN software abstracts Core and RAN and brings 5G-like benefits to 4G (with low latency and network slicing).
• Data traffic local breakout through utilization of CUPS can deliver low latency into 4G networks today.

EASY TO DEPLOY, MANAGE, AND SCALE:

• The software platform automates network optimization to reduce deployment cost. Self-configuration makes radios
  plug-and-play.
• Self-optimization reduces the need for drive testing and results in cost reduction.
• Radio is software-defined to upgrade user count and technologies, so sites can be software upgradable to
  higher capacity with COTS BBU or 5G when needed.
• Orchestration enables optimal network performance, which results in superior end-user QoE with seamless
  mobility, preventing subscriber churn.

SUMMARY

LOWEST TCO:

• OPEN RAN based solution.
• Automation reduces the need to travel on-site or use professional services.
• Hands-free optimization of PW SON saves on ongoing maintenance.

FUTURE-PROOF AND EASY MIGRATION TO 5G:

• Software platform enables 5G-native architecture which is upgradable to any 3GPP release in the future.
• The software enables any 5G migration option.
• Virtualization of gateways (like Security gateway, Small Cells gateway, Wi-Fi gateways, etc.) as VNFs
  allows flexibility to introduce new components and services within the network.

Parallel Wireless’s 4G cloud-native solution uses software to create a low-cost, low-footprint, low-power, cellular
solution for new or existing 4G networks. It removes deployment and economic constraints by being easy to install
and requires minimum ongoing maintenance which reduces OPEX. Being software-based, the Parallel Wireless 4G
solution is easy to expand and provides a 5G native architecture to future-proof the networks.
