Company profile
researched Aug 2026SureCall, Inc. develops, manufactures and sells cellular signal boosters and in-building coverage systems that amplify 3G, 4G LTE and 5G signals from all major North American carriers. Its catalog spans three segments: residential boosters for homes, cabins and small offices (Flare 3.0, Fusion Professional, Fusion4Home, Fusion5s 2.0); vehicle boosters for cars, trucks, RVs and over-the-road applications (Fusion2Go 3.0, Fusion2Go MAX, Fusion2Go XR, Fusion2Go Ultra, FusionTrek, N-Range); and commercial/enterprise systems including the Force8, Force5 2.0, 5X MAX and Fusion5X 2.0 boosters, the SignalMax hybrid-fiber DAS and the SpeedLink 5G C-band booster. The company also sells accessories such as indoor and outdoor antennas, splitters, mounting hardware, an RF signal meter and a SignalFinder 5G C-Band handheld site-survey meter.
On the enterprise side, SureCall provides building surveys, RF design, distributed antenna system deployment and installation support for facilities ranging from small spaces up to 500,000 sq ft, targeting offices, hospitals, hotels, warehouses, manufacturing plants, schools and university campuses, government buildings, retail and large venues. Enterprise systems include features such as automatic gain control, remote cloud monitoring and multi-carrier support including C-band frequencies. Products are FCC certified and, per the company, covered by a three-year warranty with U.S.-based customer service.
Founder Hongtao (Hong) Zhan is president and CEO. The company states it filed its first patent in 2001 and has been issued more than 12 patents with 9 pending, including work on wideband (five-band) boosters and Extended Range Technology (ERT), which relocates the amplifier to the roof to eliminate a cable run, and 2XP Technology with uplink power doubling.
Founding story
Hongtao Zhan, the son of two professors in Northwestern China, studied at China's top engineering school before earning a master's degree and PhD at UCLA. He joined Cirrus Logic in Silicon Valley in 1997, left in 1999 for a startup that was sold within a year, and used the proceeds to found SureCall in 2001 as the dot-com bubble deflated. His initial concept was a larger system in which a signal booster was only one component; finding the broader idea hard to implement and sell, he brought the signal-boosting piece to market as the company's first product, a single-band booster that plugged directly into a cell phone.
Business model
SureCall manufactures its own signal booster hardware and sells it to consumers and businesses, complemented by design and installation services for enterprise deployments. It runs channel programs including a Certified Installer Program with free two-level training and design support for integrators, and a retail/reseller partner program with training, certification, dedicated support and installation support.
Revenue comes from sales of signal booster hardware, antennas, meters and accessories at published list prices (roughly $50 to $1,000 for consumer and small-business products), quote-based enterprise systems such as SignalMax Fiber DAS and SpeedLink 5G C-Band, and reseller/retail channel sales including through Amazon.
Traction
SureCall says its boosters are used by hundreds of thousands of home, vehicle and business owners across North America and lists NASA, the U.S. Forest Service, Duke University and Chrysler among users. Enterprise references include a 450,000 sq ft distribution center, a regional medical center, a 500-room resort hotel, a state university campus and a multi-floor government office building, plus venue deployments at Super Bowl LIX, the NCAA Final Four in Phoenix and the Fremont Street Experience in Las Vegas. The company reports more than 6,000,000 sq ft of coverage systems installed across North America in the current year.
Latest developments
Recent product introductions include the SignalMax Fiber DAS hybrid-fiber cellular booster system for buildings from 50,000 to 500,000 sq ft, the SpeedLink 5G C-Band booster delivering data speeds up to 1 Gbps for venues and outdoor spaces, the SignalFinder 5G C-Band handheld signal meter and a C-band MIMO outdoor panel antenna. The company has publicized 5G C-band deployments at large venues including the Fremont Street Experience.

Market position
SureCall positions itself as a performance and technology leader in the cellular signal booster industry, competing on band coverage, output power and price. Recognition cited by the company includes appearances on the Inc. 5000 list of fastest-growing private companies (2016-2020), CES Innovation Awards (2017, 2020), San Francisco Business Times Fast 100 in the Bay Area (2017, 2018), a CE Pro Best Product Award (2019) and a WFX New Product Award (2019). The founder has said the company recorded year-over-year growth every year since founding and that its products are often twice as powerful as competitors' while priced lower.
The company emphasizes in-house RF engineering and patented technologies (wideband multi-band boosters, ERT, 2XP uplink power doubling), use of metal enclosures and higher-grade control board components rather than plastic, all-carrier support, a three-year warranty, U.S.-based customer support and its status as a privately held, founder-owned business that answers to customers rather than outside investors.
Technology
SureCall builds bi-directional cellular amplifiers supporting 1G through 5G bands and all major U.S. carriers (AT&T, T-Mobile, Verizon). Proprietary technologies cited by the company include the wideband five-band booster design, Extended Range Technology (ERT), which improves signal-to-noise ratio and doubles performance by mounting the booster on the roof and removing a cable run (about +3 dB), and 2XP Technology with uplink power doubling. Enterprise products add hybrid-fiber DAS architecture, C-band (3700-3980 MHz / 3500-4000 MHz) support, automatic gain control and remote cloud monitoring, with a Sentry software download and SureCall Cloud service for system management. The founder states the company introduced the first wideband 4G booster, the Force 5, in 2011, and the current Force 8 supports up to eight bands.
Go-to-market

Enterprise sales are consultative, beginning with a free building survey and RF design before deployment.
Consumers seeking better coverage in homes, cabins, apartments and small offices; drivers and RV/trucking users; and commercial and enterprise buyers in healthcare, education, hospitality, corporate offices, warehousing and manufacturing, retail, financial services, property management, public safety, government and large venues. The company also serves integrators, installers and retail resellers as channel partners.
Geography
Headquartered in San Jose, California, with U.S.-based customer support and nationwide engineering support teams; products are sold and systems installed across North America, and the company describes customers worldwide.
History
Founded in 2001 in San Jose, California, SureCall filed its first patent that year and progressed from single-band to dual-band (2G), 3G and 4G products. Zhan introduced the Force 5, described as the first wideband 4G booster, in 2011, and the company later added Extended Range Technology, first shipped in the Fusion2Go MAX. It has since expanded into 5G and C-band products and enterprise hybrid-fiber DAS systems, and has retired earlier models such as FlexPro, Fusion7, Fusion2Go 2.0 and N-Range in favor of successors. The company has remained privately held and bootstrapped by its founder.
