By anticipating future growth and planning for wireless communications that grow with the organization, businesses can save money and ensure hassle-free upgrading that keeps pace with expansion.
In 2009, Harris Communications installed wireless communications equipment for Riot Games, the creative company that produces League of Legends online gaming, to ensure clear cell phone reception inside their office buildings. The California-based video game developer has seen rapid growth, doubling its game community in the last four months. Thanks to our advance planning, their wireless communications are growing with them.
League of Legends has 32.5 million players registered, with 11.5 million monthly players. Their competitive League play offers a Season Two total prize pool of $5,000,000. Tournament play is broadcast as eSports over the web.
An increased investment in Riot Games this year by Tencent Holdings, its international publishing partner, has fueled their growth. Now expanding the product with Tencent, Riot Games currently has over 150 job openings, from artists and designers to analysts and engineers. The new staff needs cellular connectivity.
The growth plan we designed for Riot Games in 2009 included a custom wireless communications growth plan, starting with a wireless site survey to determine both current state needs and future needs should the organization expand into additional portions of the office building. We then installed scalable equipment capable of handling current and future loads, and ensured that the network of antennas could be efficiently expanded throughout the building as needed.
To replicate cell signals through an office or other commercial space, an installation requires at least one exterior antenna, one BDA (bi-directional antenna), and multiple smaller antennas to send and receive the cellular signal throughout the space. The BDA is the most expensive component, and cabling to connect the components is another large expenditure.
By choosing robust equipment and planning an efficient cabling blueprint, Harris Communications saved Riot Games the trouble and expense of replacing equipment each time they expand. Resale value for BDAs and other expensive components diminishes enormously after purchase, making replacement a very expensive option. Plus, a poorly planned cabling blueprint can lead to unnecessary and expensive re-routing projects with each expansion. So although the initial purchase price was slightly higher than it might have been, we saved Riot Games significant cost and trouble over the long term.
This past Monday, we headed out to California to assist Riot Games in their next expansion, and ensure that their new staff base receives the same high quality clear cell signal throughout the office building. All we had to do is run wires and add antennas, with no major equipment upgrades necessary.
In short, expanding on a system already purchased provides cost-effective and hassle-free upgrading, if the initial system is designed for scalability. Like Riot Games, Harris Communications knows how to equip champions for success.

When the Curtis Institute of Music in Philadelphia recently asked us to make their cell phones work inside the building, we knew it would be a special challenge. The walls between studios are padded with five layers of sound deadening material, which provides a great environment for music studies but a challenging one for cell phone signals.
Without a wireless site survey of the building, we could have installed multiple powerful amplifiers throughout the building and hopefully created a solution that would have adequately met their needs. However, by physically inspecting the premises and applying data from an RF spectrum analyzer and a signal generator, we were able to save the organization thousands of dollars and design a solution that we were confident would provide a crystal clear signal throughout the building—even in a sound-proof room.
The wireless site survey provides detailed information that enables Harris Communications to determine exactly how much signal amplification is necessary and where. This means we can purchase exactly the right bi-directional amplifier (BDA), exactly the right amounts of cable, and exactly the right number and type of bi-directional antennas for your office building or other commercial property. By avoiding the necessity of over-purchasing equipment to compensate for lack of knowledge, the wireless site survey saves the customer significant cost.
Additionally, by physically inspecting and determining strong and weak points within the building, Harris Communications can design a plan for installing antennas and cabling in a strategic manner to ensure better reception throughout the building, with no dead spots.
Without a wireless site survey, it is possible to obtain a strong signal within the building, but not only will the system be more expensive, it can backfire in terms of performance. An over-amplified signal may look like full bars on your cell phone, but the phone may not be able to power itself up high enough to get back to the antenna. And, without a properly designed antenna deployment plan, you may still end up with dead spots.
In some cases, a system that is too powerful can create noise back to the tower and shrink the coverage demographics. This will quickly get the attention of carriers, and they can demand that your system be turned off, and/or levy significant financial penalties.
To avoid these problems, every Harris Communications wireless site survey begins with a physical walk-through of the site. From the top of the building, we look for the location of incoming cell signals, from cell phone towers to repeaters mounted atop nearby buildings. We note how many and which carriers are available from each source, and the strength of the signal. This information is used to determine optimal number, location, and direction of your building’s main antennas, as well as the size of the BDA necessary.
Within the building, we inspect each office space, hallway, and common area using an RF spectrum analyzer to determine exact levels of signal and interference. Combined with knowledge of materials and location of physical barriers, this analysis enables us to select the right type and number of antennas.
Careful measurements and noting of unique conditions, including inspection of crawl spaces in the ceilings, utility areas, and other location-specific data, allow us to design an exact plan for installation of cables and wiring. With the cost of copper consistently going up, knowing the exact measurement of cable in advance saves money and simplifies budgeting.
Thanks to Harris Communications, the Curtis Institute of Music now receives clear cellular signals within offices, studios, hallways, stairwells, and common areas. However, it’s not just music schools that benefit. Office spaces, hospitals, factories, universities, and government buildings all can save money and get clearer cell phone reception with a wireless site survey.

How Cellular Reception Works
Cell phone reception is the strength of the connection the cell phone has to its network. There are a variety of factors that impact cellular signal, such as proximity to a tower. Most mobile devices use a set of bars of varying heights to display the strength of the signal where the device is located.
A signal booster an interchangeable term for cellular repeater, cell phone repeater, or wireless cellular signal booster, a type of bi-directional amplifier (BDA) as commonly named in the wireless telecommunications industry.
I simply had to post this picture……
We have had a crew out on multiple locations on the East Coast in the past few weeks. I prefer to see completed installations in person but in some cases I rely on pictures from my lead technicians. This one is a beauty; note the equipment rack and the amplifiers mounted on the wall in the background. This is a really clean job and we have another happy client. Thanks team!
