The Problem
Why Office Buildings Have Bad Cell Signal
The glass that gives your office its view is the same glass blocking your cell signal. low-E coatings reflect cellular frequencies the same way they reflect heat, steel framing and concrete floor slabs block what little gets through, and every floor farther from the roof gets worse.
When a client calls and it rolls to voicemail because the conference room has no signal, they call the next firm on their list. Staff walk to windows for calls and stairwells for messages, and the Wi-Fi calling workaround drops every time someone moves between floors.
Nobody leased this office to lose clients over dropped calls, but building codes keep demanding tighter envelopes and more efficient glass, and every upgrade that lowers your energy bill raises the number of calls that never ring.
The Solution
Complete Office Coverage. One System. Every Carrier.
The cell phone booster captures cellular signal outside your building where coverage is strong, amplifies it to commercial strength, and broadcasts it directly where your team needs it. The outside antenna sits above the roofline where signal is unobstructed, then sends it into the building through shielded cable, bypassing the walls entirely.
- All-carrier coverage from a single system. Employees, clients, and visitors on any network.
- Custom-designed for your building. An RF engineer (not a salesperson) maps your space and designs for full coverage.
- No recurring costs. One-time installation. No monthly carrier fees. No service contracts.
- FCC certified and interference-free. Does not interfere with Wi-Fi, conference room AV, building automation, or security systems, which all operate on separate frequencies.
Real Results
Multi-Tenant Office Building. No Signal.
We Fixed Every Floor.
A corporate office building in northern New Jersey with four floors of tenant space serving global logistics and pharmaceutical companies. When we tested, AT&T couldn't establish an LTE connection anywhere on the ground level. Verizon and T-Mobile were nearly as weak on the lower floors. The building's existing cellular system only supported 3G, which meant every modern smartphone was effectively without service.
Our engineers designed a cell phone signal booster with rooftop antennas feeding shielded cable into 62 indoor antennas, with commercial amplifiers in each wing's IT closet. The three-week installation covered every floor from the plaza level to the upper offices.
After the system went live, AT&T signal went from zero connectivity to strong LTE across the entire building. Employees across multiple tenants told our team they were surprised by how well their phones worked for the first time.
What Other Customers Are Saying
Office managers, IT directors, and business owners who solved their signal problems with Wilson Signal Booster.
We are thrilled. I am the communications/IT Manager for a local government/county, we installed this in our fire station. I was admittedly skeptical but after install, we experienced a definitive and measured improvement across all carriers. I encourage buyers to do their research, call customer service, and discuss the project. We did that, and we're thrilled. I anticipate buying more in the near future!
Easy install, worked as advertised. This is my third Wilson product. Office in a metal building, when doors are closed we had hardly any signal. After installing, 4 bars LTE. Great product.
Couldn't make calls inside our building (it's like a Faraday cage with its metal siding), but now we can. Hardest part is mounting the outside antenna, but it's worth the challenge. Easiest part is plug and play.
HOW IT COMPARES
Cell Signal Booster vs. Distributed Antenna System (DAS)
Cell phone boosters and distributed antenna systems are two options to solve the signal problems in your office building. Here's how they compare:
| Cell Phone Signal Booster | Distributed Antenna System (DAS) | |
|---|---|---|
| Cost | $1 - $1.50/sq ft | $3 - $10/sq ft |
| Installation Time | 1 to 2 weeks | 12 to 18 months |
| Carrier Approval | FCC certified, no approval needed | 6+ months per carrier |
| Recurring Costs | $0/year | $25,000 - $100,000/year |
| Carrier Support | All carriers simultaneously | Each carrier requires separate agreement |
| Best For | Office buildings up to 250,000 sq ft | Stadiums, airports, 500,000+ sq ft venues |

Our engineers will tell you honestly if a signal booster will work or if you need a DAS solution.

Frequently Asked Questions
Will I get bombarded with sales calls?
Will I get bombarded with sales calls?
No. After you request your assessment, an RF engineer will call you once to discuss your building. That's it. No pressure, no follow-up campaigns. If we're not the right fit, we'll tell you. We'd rather earn your trust than waste your time.
What happens after I submit this form?
What happens after I submit this form?
A signal specialist (not a salesperson) reviews your building details and reaches out within one business day. You'll have a 15-minute discovery call, then receive a custom system design with coverage map and transparent pricing.
What does office cell phone booster installation cost?
What does office cell phone booster installation cost?
The typical rule of thumb is $1 to $1.50/ sq ft, though that may be higher for complicated installations or areas with very weak outdoor signal.
Will installation disrupt our office?
Will installation disrupt our office?
We schedule installations around your business hours and can complete most of the work over evenings or weekends. Most office systems install in 1 to 2 weeks. Our team coordinates with your facilities or office manager to avoid disruption during working hours, and every zone is tested before the team leaves.
What's the typical cost for an office building?
What's the typical cost for an office building?
Every building is different, so exact pricing depends on your building's size, number of floors, construction type, and existing signal conditions. As a general guide, commercial office installations typically run as little as $1 per square foot of coverage. A 5,000 sq ft single-floor office is a different investment than a 50,000 sq ft multi-floor building. Your free assessment includes a detailed, no-obligation quote specific to your space.
Is my office too small or too complex for this?
Is my office too small or too complex for this?
We design systems for everything from small professional suites to large multi-floor commercial buildings. Offices under 5,000 square feet may be candidates for a self-install booster kit that you can set up without professional help. Larger or multi-floor spaces typically need a custom-designed system. The free consultation determines what your building actually needs.
Will this cover all carriers and devices?
Will this cover all carriers and devices?
Yes. Every system covers all major carriers (AT&T, Verizon, T-Mobile, and others) simultaneously. Employees, clients, and visitors on any cellular network will have improved coverage. It works with all phones, tablets, hotspots, and any cellular-connected device.
Will this interfere with our Wi-Fi or phone system?
Will this interfere with our Wi-Fi or phone system?
No. Signal boosters operate on cellular frequency bands (617 to 2700 MHz), which are completely separate from Wi-Fi (2.4 and 5 GHz), Bluetooth, conference room AV systems, building automation, and security systems. They are FCC certified with automatic safeguards that prevent interference with any existing systems in your building.
What warranty and ongoing support do you provide?
What warranty and ongoing support do you provide?
All systems include a 2-3 year hardware warranty from the manufacturer and lifetime phone and email technical support from our team. Signal boosters are passive systems with no moving parts, designed to operate maintenance-free for years. Our team is available at 1-888-974-8237, Mon-Fri 9am-5pm ET.
Why won't my carrier just fix the signal in my building?
Why won't my carrier just fix the signal in my building?
Carriers build towers to cover geographic areas, not individual buildings. Indoor coverage is the building owner's responsibility. Carriers only invest in high-traffic venues like airports and stadiums where the ROI justifies it. For office buildings, a signal booster is the practical fix because it works with all carriers simultaneously, requires no carrier involvement or contracts, and installs in weeks instead of the 12 to 18 months a carrier DAS project takes.
