Comcast’s Xfinity Communities says it has signed up more than one million users in multifamily housing properties like condos and apartments in 37 states, in just over a year since its initial launch.

Xfinity Communities sells and markets Xfinity X1, home security and automation and phone services. Xfinity Communities’ ACN is powered by fiber technology, which allows building owners and property managers to offer the Internet and WiFi speedsto their residents via fiber-to-the-building (FTTB) or fiber-to-the-unit (FTTU) solutions that can scale to gigabit speeds with customized packages or a DOCSIS-based deployment.

Many Xfinity Communities and their residents have a dedicated Community Account Representative (CAR) for technical support or sales questions. These support personnel act as a concierge service for property management by helping to coordinate installations, troubleshoot disruptions, process service changes and assist with moving and property transfers.

The quick growth is due to growing demand for high-speed technology services from both prospective residents and building owners across the country.

“The reality today is that residents take into consideration whether properties have access to the latest Internet, WiFi, TV, home automation and voice technologies when deciding where to live. As a result, many leading apartment owners and property managers have looked to us to provide the cutting-edge services they need to keep their residents happy and stay ahead of the competition,” said Michael Slovin, vice president, Xfinity Communities, in a statement. “We’ve made tremendous strides since we first launched in 2014, and as we continue to grow this business, our top priorities are to provide an even better network, better entertainment options and better customer experience so we form long-lasting relationships with the property managers, building owners and residents we serve.”
