These days people can't live without their cell phones. That's why Nextivity is making cell signals more readily available, even in difficult spaces like LEED certified buildings, warehouses and reinforced basements, with its Cel-Fi PRO EXA

Nextivity says the Cel-Fi EXA includes an external antenna connector for its PRO Smart Signal Booster, helping customers remain connected to the outside world. 

"Cel-Fi PRO has been well accepted in the worldwide market, but there are certain circumstances that require an external boost. Cel-Fi PRO EXA provies the means to strengthen the off-air donor signal so tha tusers can get the most out of their Cel-Fi PRO systems," says Werner Sievers, CEO, Nextivity. "It demonstrates Nextivity's unwavering, long-term commitment ot expanding our product line and addressing additonal markets."

Nextivity says the product is able to take the signal from nearby cell-phone towers to improve the signal quality of 3G/4G/LTE in spaces as large as 15,000-square feet. 

Nextivity points out that when the Cel-Fi PRO EXA is combined with its Cel-Fi WAVE application, professional integrators can accurately aim the external donor antenna to maximize incoming signal strength to achieve as much as 100dB of gain on their clients' cell-phone signals. 

The San Diego-based company adds the cost-effective Cel-Fi PRO EXA solution produces greater signal strength reception capabilities than older-generation BDA/repeater products to provide value in challenging building environments.
