Case Study: How one of the World’s Largest Package Delivery Companies is using iBwave to Manage Thousands of Wi-Fi sites

As one of the largest package delivery and logistics companies in the world, one of our newest iBwave customers came to us wondering how our software could improve their existing process for deploying and managing their many Wi-Fi networks across thousands of their facilities around the world.

Here is the story. 

From the start, it became clear that the biggest challenge this company was facing was the sheer number of sites they had to manage around the globe. With tens of thousands of facilities, all ranging in size, type and location, logistical and process challenges were proving to be costly.

The key challenges they had were:

  1. How to manage their thousands of Wi-Fi networks across many different locations in a more efficient and cost-effective way – in particular how to easily share all data & documentation in a central location
  2. How to collect cellular network data and Wi-Fi network data at the same time to eliminate the dependence on third party companies
  3. How to improve the quality of the network designs to reduce troubleshooting post-install
  4. How to reduce the time it takes to produce the required costing report

To solve these issues, this customer is using the iBwave Design Suite — a powerful combination of iBwave MObile Planner (our mobile app for surveying), iBwave Design (our powerful network design software), and iBwave Unity, our SaaS-based enhanced cloud solution that synchronizes all information and then allows you to monitor, manage and access all of your sites and documentation from one place.

To give you a quick high-level overview of how they all work together, here is a visual of how they interact with one another through the lifecycle of a Wi-Fi network design project from survey to design, deployment and maintenance.

Let’s go through each of the key challenges to see specifically how they were resolved. 

Maintaining All of Their Wi-Fi Networks Across Thousands of Sites

Managing multiple sites is a big challenge for many large Enterprise companies and this customer was no exception. With tens of thousands of facilities located across the United States, the biggest challenge was how to manage the design documentation in a single location to simplify the maintenance and troubleshooting of the network for the ‘Corporate Technical Support Group’ technicians located at the facilities across the globe. 

With their previous set of tools,  survey and design documentation and reports were not centralized in a place where the technicians at the different facilities could access them when troubleshooting or validating a network’s performance. There was also the issue of having to ship a device with dongle licensing out to the facilities whenever a troubleshooting issue arose—often a time consuming and expensive cost.

The Solution

To solve these issues, the powerful combination of iBwave Mobile Planner, and iBwave Unity were implemented.

iBwave Unity is our advanced cloud-based site and project management software that gave this customer a single repository to keep all of their documentation — designs, survey data, site documentation — centralized and synchronized. For the technicians on-site this means they can now easily access previous design and survey data, to have a baseline and test against. 

The problem of having to ship a technician a testing tool each time was solved with our mobile app, iBwave Mobile Planner. With no dongle licensing to worry about, various sites can now keep their own mobile app (usable on any Android mobile device) and use it to survey and test each of the facilities when there was an issue.

The Result

By using the integrated solution of iBwave Unity to centralize site survey information collected by iBwave Mobile Planner, technicians on-site can now easily access previous design documentation and baseline survey measurements for any troubleshooting efforts. 

While no exact number can be given because every site and every troubleshooting effort varies, it’s been seen by our customer that this solution saves them an estimated 50 hours for the average site/troubleshooting effort.

Streamlining the Site Survey Process & Enabling a Converged Approach

Convergence—a word we are hearing more and more from our large Enterprise customers when it comes to managing their network and for this particular customer, an important requirement for doing site surveys.

 Why so important?

While the size of their many facilities varies, the largest and most active facilities (storage and shipping warehouses), can often span more than two million square feet and many of their apps rely on the cellular network to perform. For that reason, it was important for this customer to understand not only their Wi-Fi coverage, but also their cellular coverage and the impact of it on the Wi-Fi network.

Prior to iBwave, to collect the data for the cellular network it was a complicated and costly process, with some key challenges:

  • Outsourcing—since they did not have their own tools to survey cellular data, they had to outsource the job to a third party company often leading to very long delays, and weeks long survey process. 
  • Multiple Site Walks—without the ability to collect the cellular data at the same time as the Wi-Fi data, multiple site walks had to be done to get a complete picture of the networks.
  • Centralized Documentation—without a central place to store and share all site survey data and documentation, surveys would often have to be repeated.

 The Solution

These challenges were resolved with the use of our cloud-based site management software iBwave Unity, and our mobile app, iBwave Mobile Planner, to perform the surveys.

With the ability to collect both cellular and Wi-Fi data measurements at the same time using the mobile app, the dependence on a third party to survey the network was eliminated, as was the challenge of having to do multiple site walks to get all data.  And with the integration of the mobile app  to the iBwave Unity cloud solution, all survey data collected is now be stored in a central cloud repository, eliminating any risk of lost data that needs to be recollected. 

The Results

While not able to put an exact number on it, the time and cost savings are significant now that there is no need to outsource the collection of the cellular data and all data that is needed for a complete design is documented in the cloud where it’s easily accessed by the design team. A survey that may have taken weeks before to gather all data can now be done in days.

“The ability to gather both cellular and Wi-Fi network data ourselves at the same time, in one tool without the help of a third party, is invaluable to us in terms of time, cost and documentation.” – Senior WLAN Design & Support Engineer

Finally, let’s look at the last challenge resolved by using iBwave software—design optimization and quality.

Improving Wi-Fi Network Design Quality & Optimizing Costs

When it comes to any type of wireless network design, if the design is not done well from the start, then it can lead to two things: 1) costly troubleshooting and re-design later, and 2) a design that is not optimized and therefore more expensive than it needs to be.

These two issues are the main reasons our iBwave software is so focused on enabling design optimization and network performance prediction accuracy. We pride ourselves on making sure our customers have the best wireless network design software to deliver the highest quality of designs to their end-users in the most cost-effective way possible. For this customer, the quality of the designs they were getting from their previous design software, and the level of troubleshooting they had to dedicate their resources post-installation, was proving to be a costly challenge. As was the over-designing of the networks – why add more access points if coverage and capacity can be maximized for less?

The Solution

Both of these challenges are ultimately resolved by the powerful features and prediction capabilities in iBwave Design. With features like 3D modeling, inclined surface modeling, propagation through floors, and prediction calibration, the quality and accuracy of the designs will improve significantly.  And accurate prediction results leads to high-quality optimized designs and ultimately less troubleshooting post-install. 

 Simplifying Reporting

Reports and documentation are part of almost any wireless network design project and it is no different for this large Enterprise customer. Especially accurate costing reports.

Prior to iBwave the process to produce these types of reports was manual, tedious and time consuming, often taking almost an hour to put one together, and often at the risk of human error as there was no way to automatically generate them.

The Solution

With iBwave, the time previously spent on manually creating reports is eliminated and costing reports are generated in a matter of seconds with one click. Additionally, costing reports can now be generated at both the individual project basis, or across several different projects, using iBwave Unity. For example, if they want to track costs across particular building types (warehouses, depots, etc) or for a certain region, that is now simple to do in either a report or dashboard. Here are some costing report examples.

Here’s are a couple examples of generating a Bill of Materials, and a Cost Details Report ?

Conclusion

By using the powerful solution of iBwave Unity + iBwave Mobile Planner and iBwave Design, this large Enterprise customer is now able to manage the thousands of sites across the world from a single location – resulting in higher-quality Wi-Fi networks and less time and money spent troubleshooting them.

Wi-Fi Design Strategies in a Converged World Webinar: Your Questions Answered.

We had an amazing webinar on “Wi-Fi Design Strategies in a Converged World”. Our guest speaker Ronald van Kleunen, CEO of Globeron did a great job discussing why it’s important to understand the impact of convergence while designing high‑performing Wi‑Fi networks and how different wireless technologies can work together.

As promised Ronald, along with iBwave’s Vladan Jevremovic and Ali Jemmali took some time to answer most of the questions that were asked by our enthusiastic audience. This is the first in a series of blog posts where we will share these answer with you. So read on and feel free to comment and share your feedback.

And in case you missed this webinar or simply need a refresher, here is a link to the recording: Wi-Fi Design Strategies Webinar.

This week’s topic: Wi-Fi Design

1- How do you verify the design after implementation?

[Ronald]

RF Coverage validation can be done in iBwave Wi-Fi with the Site Survey tool (there is a Passive and an Active Survey option).

  • Passive means the Wi-Fi adapter is not connected to a network and visualizes RF coverage areas of different SSIDs (Service Set Identifiers) called an “RF Heatmap”
  • Active means, the adapter is connected to an AP (“BSSID – Basic Service Set IDentifier”, like a Single AP) or to an SSID (which can exist out of multiple APs covering an RF network)

To validate RF Capacity is a bit more difficult, there are some “Wi-Fi client simulators” creating multiple clients to connect to the AP (to test the capacity of the clients associating, throughput tests, etc.). Alternatively, real clients can be used, but this is very costly.

2- What are the expected trends of Wi-Fi design in the context of future 5G?

[Ronald]

Currently 5G is a hot topic for both outdoor and indoor “small cells” architectures for cellular and mobile devices, but one of the difficulties in many countries is the availability of the 5G Spectrum (700 MHz) and the auction model’s governments will implement for operators to bid-on. As an example, Singapore is one of the first countries that gave spectrum to do trials for 5G. Note that Spectrum management does not mandate the technology used in the assigned spectrum.

Both technologies will co-exist for several reasons:

  • Price (Wi-Fi / unlicensed spectrum = cheap vs 5G / licensed is expensive)
  • Adoption/Developers, more developers with Wi-Fi enabled equipment vs 5G (think about IoT over Wi-Fi, versus IoT over 5G)
  • Public wireless networks might be preferred by 5G, because of better roaming / coverage (e.g. over a country) vs Wi-Fi being limited in RF coverage and roaming options
  • Enterprises probably will stick to Wi-Fi for their own production network and operations, because of confidentiality of data to remain within the facility and not going via the DataCenters of the Telco providers

3- I want to know the weak, strong areas of the AP ‘s coverage

[Ronald]

Vladan of iBwave did an excellent presentation how to use iBwave Wi-Fi from an RF Design perspective (Ref: overcoming the capacity challenge available via this webinar link) , but also the survey tool will help to find the weak areas.

4- Capacity Planning & Channel/frequency Planning

[Ronald]

Yes this is covered for Wi-Fi and can be automated in the iBwave Wi-Fi tool for areas/zones, number of active devices and applications (e.g. e-mail and data requirements,voice requirements, etc.) it is very detailed.

Vladan of iBwave did an excellent presentation how to use iBwave Wi-Fi from an RF Design perspective (Ref: overcoming the capacity challenge available via this webinar link) , but also the survey tool will help to find the weak areas.

5- How do I design for capacity instead of coverage of Wi-Fi? How do 2×2:2, 3×3:3 or 4×4:4 APs differ in designing for capacity?

[Ronald]

Capacity – see Vladan’s webinar as he covered the RF capacity planning ((Ref: overcoming the capacity challenge available via this webinar link)

[Vladan / Ali]

2×2:2, 3×3:3 and 4×4:4 are different focusing on the spatial streams and Tx and Rx radios for max. DATARATES only  (thus not throughput as many factors impact the throughput). Streams to be used depends on the client as well what their capabilities are. To design, these APs need to be in the iBwave Wi-Fi tool which takes into account the Antenna RF propagation.

6- How accurate/ feasible is it to design networks without being physically present in the site?

[Ronald]

The RF planning tools can plan till a certain extent (including wall attenuation levels, etc.), but what cannot be planned in advance are:

  • Neighboring buildings with Wi-Fi and non-Wi-Fi devices operating in the same spectrum
  • Other devices in the building (e.g. Microwave ovens in 2.4GHz)
  • Other equipment in the building (e.g. metal cabinets, racks in a warehouse, storing different products at shelves in a supermarket)
  • People walking around the facility.

7- How does RF mapping gets affected by different flavors of Wi-Fi (802.11n, ac , ah etc…).

[Ronald]

In the RF mapping / planning tool, the way the technology works (like number of spatial streams, bandwidth 20 MHz, 40 MHz, 80 MHz, Transmit Output power settings of the AP, etc., protocol used) are all kind of variables impacting the RF propagation and RF Heatmap visualization (but there are more factors affecting it, like number of APs on the same channel, building materials like concrete walls, etc.).

8- How to remove Co-Channel Interference and how to measure it?

[Ronald]

Proper channel planning is important, but eventually multiple APs will be on the same channel (Co-Channel interference). SNR (Signal to Noise Ratio) is one of the factors for client devices to decide to which AP to connect to, but there are more factors (4x conditions: Physical Carrier Sense, Virtual Carrier Sense, IFS completed and Random Back-off Timer / Slots completed).

Adjacent Channel interference (overlapping channels is worse) as the APs cannot hear each other and therefor Co-Channel interface is a bit better as the Wi-Fi frame can be interpreted by the other devices on the channel. Furthermore, take into account Client Induced Interference as these are also radio transmitters and can affect the communication of other APs / devices on the same channel.

To measure Co-Channel interference:

  • Spectrum Analyzers
  • Reconnaissance tools
  • Protocol Analyzers
  • Integrated Site survey tools

9- During the recorded demo, you went from your predictive plan straight to installation, then conducted a verification survey afterwards. Would you not do a pre-deployment survey as well to collect surrounding passive data and confirm your predictive AP locations are correct within a live environment? (in case live propagation differs to your prediction).

[Ronald]

Correct (the demo was a bit focusing on key aspects), but you are right, that need to be added to video. The RF planning is done, but you always need to go on-site to understand the environment as it is always different than expected. Also, measurements need to be done to check the wall types and attenuation levels, leakage of neighboring buildings Wi-Fi networks, furniture in the office (like metal cabinets), other equipment operating in the same frequencies (like microwave ovens).

10- What are the main criteria to design a Wi-Fi network, is there a specific standard or a table showing different Service Levels?

[Ronald]

No there is not, as covered in the presentation there are several organizations involved in standardization and in progress for Wi-Fi networks by the WLAN Association (WLA)

In general, the approach works for any wireless network

  • Get the requirements (end-users, # devices, roaming, costs, etc.) “Red book”
  • Design the network “Blue book”
  • Install “White book”
  • Validate “Green book”
  • And in addition, there should be also one covering
  • Operate and Monitor

It is hard to give Service Availability Levels for wireless networks.

Here are some videos:

  • WSMS (Wireless Service Management System)
  • Need for Wireless Service & Security Standardization

11- Key parameter for design and planning requirement, Site Survey requirement, Planning guideline.

[Ronald]

Focusing on the Wi-Fi industry that is something that does not exist. There are books (like the Sybex version of the Certified Wireless Design Professional, but these are checklists of “what need to be done” and not “how it needs to be done”. The Wireless LAN Association (WLA) is in an initial progress looking into this (the 4x books, Requirement phase, Design phase, Implementation Phase and Validation Phase). Some vendors have a kind of wizard built-in and like iBwave parameters have been set already for different type of applications (like e-mail, voice, video traffic) and it can be customized as it depends also on the vertical market segment.

12- How should I consider APs that are on adjacent floors to provide Wi-Fi coverage and capacity? Or do I not consider those and design each floor independently?

[Ronald]

Correct. You typically design per floor level to have good RF coverage and Capacity for clients for different areas. If you have open spaces (like Atriums, you need to take that into account, maybe AP Transmit Radio Powers need to be reduced to avoid RF leakage through those Atriums, which means that suddenly clients see too many APs)

In the design tool (between the floors) you also need to see the attenuation levels (e.g. a very thick concrete floor or not), but if the APs can hear each other in 3D, then you also need to look at the Channel allocation that they do not interfere on the same channels (e.g. APs “stacked” on Channel 1).

13- I would like to know more about in-building design, Wi-Fi Design and DAS Design

Winter Conference: https://www.bicsi.org/winter/2017/attendee.aspx?id=8734

14- How is Wi-Fi monitored i.e. capacity limits, interference, etc. just like other technologies?

[Ronald] 
There are several product vendors that have Wi-Fi Management systems where they get the information from the Wireless infrastructure components (like APs, Controllers, etc.). Some do only dedicated Wi-Fi Performance Management utilizing a centralized server and so called “Sensors” being deployed to monitor the Wi-Fi traffic and similar systems exist to monitor the Wi-Fi Security (Wireless Intrusion Detection / Prevention Systems) using Sensors. The advanced systems can do a combination and utilizing dual-band or tri-band APs were 1 or 2 radios provide Wi-Fi services (2.4 GHz and 5 GHz) and another radio provides Senso services

15- Is there anything on Wi-Fi SON (distributed or mesh) ?

[Ronald]

Self Organizing Networks (SON): https://www.qualcomm.com/news/releases/2016/01/05/qualcomm-launches-wi-fi-son-self-organizing-network-solutions-simplify-wi

I do not have experience with this “SON” technology and how it operates. It looks proprietary to certain vendors. Other vendors also have kind of “self-healing” type of technology, like Radio Resource Management (RRM), Adaptive Radio Management (ARM), Smart RF, Channel Fly, looking and optimizing the RF aspects, but the other key features mentioned in SON are also supported by most vendors:

SON – Key features include:

  • Self-configuring that enables plug-and-play deployment (most vendors support adaptive AP adoption to controllers/cloud and management)
  • Self-managing that offers autonomous performance optimization
  • Self-healing actively detects and resolves connectivity bottlenecks (as mentioned above)
  • Self-defending that secures the network from unauthorized access (integrated WIPS systems).

16- Do you have High Density WLAN examples?

Case Study: Designing a Small Cells Network of a Large Hotel 70 percent Faster

In this blog I’ll take a look at a recent project done by one of our customers to design a small cells network for a large business complex hotel located in Asia. By using iBwave, and in particular the collaboration capabilities our solutions provide, our customer was able to expedite the project time by 70% while meeting all the key performance indicators. 

Here we go. 


What was the venue?

  • 5 Star Business Hotel
  • 600,000 sq. ft
  • 14 floors
  • 437 rooms

How many users are we talking?

On average there are 1,500 to 4,000 users accessing the network with their mobile devices for an average 3 hours per day. 

What technologies were they designing for?

This project was a small cells project, using both the cellular and Wi-Fi technologies.

Wi-Fi 2.4 Ghz & 5 GHz

LTE 2.3 GHz

Great, what results were they achieved?

Key Performance Indicators were set as requirements before the project began for both cellular and Wi-Fi performance. 

  • 3 Mb/s per user
  • RSRP -98 dBm > 95% area
  • Wi-Fi -65/70 dBm > 95% area

How did they use iBwave during the project?

For this project the powerful combination of:

  • iBwave Mobile Planner (mobile app to gather site survey measurements, images, notes and do a preliminary design)
  • iBwave Design (power PC software to design both cellular and Wi-Fi networks)
  • iBwave Unity (cloud-based site and project management software accessible via the web)

were all used in different phases of the project, by different teams of people. The key to this project was how they utilized the cloud-connected iBwave Unity site management software in order to keep all of their site and project documentation synchronized and up-to-date throughout the project. 

How they used each project and when can be summarized by something like this:

Let me break this graphic down further. 

To start the project, field technicians completed a site survey using iBwave Mobile Planner (a Wi-Fi/Small Cells site survey and design app) , to document the site (measurements, images, notes) and do a preliminary design while there on-site at the hotel. Once the site survey information had been gathered, the field technicians saved that project to the cloud where it could be immediately opened and accessed by engineers back at the offices in the powerful PC based network planning and design software, iBwave Design. Once the file was open, the engineers had all the site survey information right there on the floor plan with all the images and notes captured by the field team. In this case the customer was using iBwave Unity, our enhanced version of the cloud which also acts as a site management tool instead of the basic cloud that comes with only 10GB and no site management functionality. Why iBwave Unity? Because this customer does so many projects a year, iBwave Unity gives them a way to gain insight and control over all the sites and projects they do – including dashboards, reporting, workflow management and compliance checking. 

Once the design was completed in iBwave Design, field technicians or engineers validated the network using iBwave Mobile Planner, to ensure network design requirements were met and no issues required further troubleshooting.

What were the design results?

390

SMALL CELL ACCESS POINTS

17KM

OF CABLING


What reports did they use?

There were 7 key reports generated throughout the project

  • Equipment List (Bill of Materials)
  • Output Maps
  • Cable Routing
  • Cost Details
  • Annotation
  • KPI Compliance
  • Capacity 

Here are some pictures!

So, how long did all of that take to do?

Using the combination of iBwave Mobile Planner, iBwave Design and the cloud-connected iBwave Unity, the project was completed in….

3 DAYS

1 SITE VISIT

That is 70% faster than it would usually take them to complete the same project (about 10 days, 3-4 site visits). 

Check out also our eBook about Wi-Fi Challenges and Best Practices in Hospitality written with the help of the industry expert Ronald van Kleunen. We’ve included a detachable customer requirements checklist in the book, take it with you to the field and keep it handy!
