Quality

Integrity, honesty and reliability

are fundamental to our business

Core Values

Quality, measured by consistent client success, satisfaction, trust

Service, focused on client-centric, flexible, adaptive delivery methods, and comprehensive diligence

Excellence, demonstrated by professionalism, competence, attention to detail, and precise execution

Innovation, learning how to be creative in pragmatic applications of good theory



Design Philosophy


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


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


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


Design Approach


Adaptive, client-centric method ensures requirements and constraints are weighed properly in design decisions

Adaptive to client’s process Client requirements, experience, and delivery

Results that are focused on the client’s mission

Organized execution Proactive diligence Timely results Optimal Value

Provide timely reports and support to client Daily status, progress, or risk reports, as required

Design Process Abstract

Design Drivers


Design Method continued

In creating a simple, elegant architecture, client requirements and venue constraints drive the number and configuration of zones, sectors, nodes, and antenna..

Key neutral host design drivers:

Coverage- Link-Budgets(worst performing) and Number of:

WSP/carriers, frequency bands, technologies, zones, sectors and antenna

Capacity- performance metrics include:

MIMO/SISO, scalability, venue aesthetics, MDF/IDF closets, HE power, KPIs, etc.

Design CharacterizationSite Survey: Characterize venue layout (with photos)

Thoroughly identifying and noting, on venue map, practical constraints and

impacts on system design and implementation

MDF, IDF, Amp Headroom, antenna PoA,

Necessary for accurate installers’ notes

RF Situation: Benchmark (BM) testing data to characterize the external macro signals in

and around the venue Necessary for efficient and accurate design models

DAS to macro Dominance, and KPI Predictions/Model fine-tuning
