Design Philosophy
Proprietary & Confidential
A problem well defined is half solved Each venue brings a unique set of requirements and constraints
Venue constraints, sensible link budgets, and OEM selection will influence system architecture, deployment, performance, scalability, and value/time
Together with constraints, requirements drive designs Optimal designs have a rational coherent “design narrative” based on
requirements and constraints. This logical story explains the design decisions.
Adaptive approach allows flexibility in methods to, Handle any stakeholders’ design scenario
Delivery of quality, efficient design outcomes quickly
Proactive experts identify and bridge gaps. Expert design professionals have extensive iDAS/Small Cell SDLC and
performance management experiences
This helps in designing realistic, practical, efficient models to specification.

Optimal Designs
Proprietary & Confidential
Perhaps the ideal is an idea, however we define optimal designs as practical, accurate architectural models that meet performance and scalability needs efficiently.
Requirements, venue constraints on architecture, and RF environment drive designs, but an expert: Skillfully crafts a design narrative to justify design options
Grasps how OEM selection drives and constrains design
Considers link budgets with headroom, maximized fiber to coax ratio, proper testing, and antenna
Recognizes how antenna types and Point of Attachment make a significant impact on performance

A Compelling Story
Proprietary & Confidential
Design Philosophy
- Every (IB) network design has a story; the better the story, the better the outcomes.
The Design Narrative: Expertly lays out the system’s drivers and constraints, then logically
aligns design decisions to establish an architectural model based on client requirements that is realistic, scalable, and efficient.
Provides a walk through of design options considered, justifies design choices made and rationalizes the abandoned alternatives with coherent pragmatic logic.
Clarifies how to overcome practical limitations to achieve requirements with a compelling value proposition
Impact: Fewer design errors, more confident design reviews, accelerated times to market, and smooth efficient construction, commissioning, and optimization phases
