5 Best Cell Phone Signal Boosters for Warehouses

Reprinted with permission from the WilsonPRO blog.

If you’ve ever tried to make a call or access the internet with a smart device deep inside a warehouse, then you’ve likely been frustrated by weak or nonexistent cell signals. But your cellular service is not necessarily the problem. Cell signals falter as they travel through building materials, equipment and inventory, and they weaken as they extend to the distances and heights in such large spaces.

Whatever the type of building, location or use, unimpeded connectivity is a priority. Weak signals and dead zones kill productivity, impede safety and cause angst for employees, visitors and tenants. While Wi-Fi is the standard for connectivity, it can be inconsistent in many scenarios. Cell signal can be the best (and, at times, the only) option for connecting to the internet in large buildings.

How Do Cellular Amplifiers Improve Inside Signal?

Cellular signals are radio frequency signals that start out strong at the cell tower transmission site. As they travel across miles to reach your facility, obstructions such as trees, mountains and even open air can weaken the signals. Already weakened when they arrive at your building, the signals must also penetrate building materials, walls and other obstacles to provide cell reception. This is why it’s often easier to get a decent connection near the window but nearly impossible near the center of a warehouse.

Cellular signals operate with signal strengths between -50 dBm to -120 dBm. The closer you get to -50 dBm, the better the signal; the closer you get to -120 dBm, the poorer the reception. Building materials subtract dB from cell signal trying to enter a large building, especially a metal one.

Cellular amplifiers detect and pull strong outside cellular signal inside a building, increase the signal’s dB through a booster unit and spread the stronger signal to the inside antenna network. The inside antennas then spread the boosted signal throughout the facility. These boosters can pick up cell signals up to 30 times fainter than what a mobile device can detect, improving call quality and data reception inside buildings of all sizes.

Before You Buy

Before investing in a cellular amplification system, you’ll need to have a site survey performed. This survey should factor in building materials, the layout of spaces and racking, inventory levels and types of devices and applications to be used. Authorized WilsonPro representatives are professionals with expertise in facility implementation.

A site survey will also address any challenges to day-to-day cellular service you might face in a warehouse setting, including:

  • Antenna type and placement
  • The Internet of Things and movement of powered equipment
  • Interference from racking or stored materials
  • Firmware on access points

The cellular amplification kit you need largely depends on the size and location of your building as well as your specific connectivity needs. Signal Connect can consult with you by phone to help you discover how a cellular amplifier best fits your situation.
