CAR-SA is a company with more than 17 years of experience offering solutions in IT and Telecommunications. They have a presence in 54 cities strategically located across the country to offer their services wherever the client may require them. With an innovative client-first approach, CAR-SA’s vision is to provide infrastructure management service of the highest standard. Aligned with this vision, and aware of the trend towards mobility in devices that make use of Wi-Fi technology, they are committed to offering quality service in this vital market segment.

INTRODUCTION

Knowing that software plays a crucial role in the successful deployment of a Wi-Fi network, CAR-SA searched far and wide to find the best tools to support their goal of excellence in wireless design. The previous software they were using simply wasn’t cutting it. Then CAR-SA discovered iBwave.

iBwave helped CAR-SA achieve their objective of designing high-performance Wi-Fi networks for their customers, and thanks to the software, their team of Wi-Fi engineers can carry out site surveys, design, maintenance, and troubleshooting, all in a single project with key information centralized in the cloud.

But it wasn’t always this way. Before adopting iBwave, CAR-SA had some challenges with their existing workflow of network design for warehouses, convenience stores, gas stations and offices. Spread out sites like these present unique challenges when designing networks, and their existing software did not have the features to solve these issues.

THE CHALLENGES

SHARING SITE SURVEY INFORMATION
With sites spread out across the country, engineers had to be dispatched from head offices to complete site surveys, and results had to be manually sent before design production could begin. In the past, CAR-SA’s survey results were sent via email attachments in many different formats, which made it tricky to compile data in an organized manner. Additionally, their engineers had varying levels of experience and skill, often leading to survey results that were inconsistent in detail and quality.

To further complicate things, the lack of a mobile solution meant engineers had to use bulky laptops (of varying performance) to complete surveys. Some audits required up to 5 kilometers of walking, which made carrying expensive, heavy pieces of equipment risky and inefficient.

DESIGN OPTIMIZATION & PREDICTION ACCURACY
Issues with previous software caused incorrect wall attenuation values, inaccurate interpolation, and had no consideration for reflection and diffraction, which can have a huge impact on prediction accuracy in a complex environment like a warehouse. As a result, customers often ended up buying and installing more access points than required because the design was not properly optimized.

These issues also led to corrupt results, and some warehouses required up to four surveys before their network design was perfected. Customers were left understandably frustrated.

REPORTING
With previous software, only 2D report visualizations were available. Limited options made it difficult to provide an accurate visualization of the network’s design and performance to customers. The lack of consistency in documentation and report generation also made it a challenge for CAR-SA to provide essential information to their clients in a format of their convenience. With reports being sent via email in a variety of different file types, projects quickly became disorganized.

THE SOLUTION

THE RESULTS

STREAMLINED SITE SURVEYS
Once CAR-SA partnered with iBwave, sharing key information within the team was simplified. With engineers all using iBwave Wi-Fi® Mobile to survey, site information can be instantly shared with project stakeholders across the country through the iBwave cloud.

Cloud connectivity enables engineers to capture pictures of warehouse interiors and annotate to design specialists at head offices. This simplifies the process for network troubleshooting and reduces the number of site surveys required per venue. It also allows them the ability to capture accurate date measurements, and even complete preliminary designs with heatmaps. iBwave’s shared licensing across devices meant that the software could now be used as needed, regardless of warehouse location.

Bulky laptops for site surveys became ancient history, too. Engineers now use iBwave Wi-Fi® Mobile to perform surveys, drastically reducing the time, cost, and hassle of sharing results.

ACCURATE PREDICTION RESULTS & OPTIMIZED DESIGNS
“With features like 3D modelling and prediction accuracy, iBwave does things a little differently than other wireless network software vendors.”

iBwave’s 3D modelling, ability to consider reflection and diffraction, and advanced prediction algorithms provides CAR-SA with unprecedented accuracy. Customers no longer buy unnecessary equipment or access points, and the number of site surveys required to complete projects has dropped.

The bottom line? CAR-SA provides excellence to their clients by providing them with accurate high-quality Wi-Fi network designs that work correctly from the time they’re activated.

REPORTING
iBwave Wi-Fi® offers CAR-SA a host of report generation features that prove invaluable to streamlining the design process. The Access Point report function provides CAR-SA’s customers with a convenient at-a-glance breakdown of AP placement information. The report displays AP locations against the building floor plan, and also indicates which channel and band each access point operates on.

3D visualization of the network’s heatmaps are also invaluable for CAR-SA. Since key decision makers are not always technically inclined, iBwave reports provide them with stunning 3D visualizations of how a design will be installed and perform, leaving them confident in CAR-SA’s ability to complete the project.

In the past, CAR-SA were unable to provide reports with this level of detail and simplicity. And regardless of the report type, iBwave Wi-Fi® allows CAR-SA to export in the file format of the client’s choosing. This helps keep projects organized and customers satisfied.
