Company’s Manhattan Wi-Fi Network Becomes Premier Next Generation Hotspot

MIDDLETOWN, R.I., June 13, 2013 – Towerstream Corporation (NASDAQ: TWER), a leading 4G and Small Cell Rooftop Tower company, today announced that its Manhattan Wi-Fi network is one of the first networks to be named as a certified Next Generation Hotspot (NGH) by the WBA’s Interoperability Compliance Program (ICP).

“The WBA’s ICP is a crucial step towards end users having seamless integration between 3G/LTE networks and reliable high capacity Wi-Fi networks. Towerstream engineering has been working closely with the WBA team and we couldn’t be more pleased with the results,” said Arthur Giftakis, VP of Engineering and Operations at Towerstream.

The ICP outlines a set of Wi-Fi guidelines for mobile operators to standardize the way devices connect to and roam onto Wi-Fi networks. These guidelines include: security, data offload, device authentication, network implementation, charging models and billing mechanisms.

“With the WBA’s Next Generation Hotspot, Wi-Fi networks will become seamlessly integrated into the mobile lifestyle and greatly enhance the user experience,” said Jeff Thompson, CEO of Towerstream. “This tremendous step to integrate Wi-Fi into heterogeneous networks and mobile networks offers carriers a new opportunity and possible new revenue streams. We continue to applaud the WBA for their tremendous leadership in setting the path forward to a better connected world.”

Shrikant Shenwai, CEO of the WBA, said: “It is great to see how the operator community has embraced the ICP, recognizing its value in improving the way in which it works together to deliver a more consistent roaming experience. Towerstream is one of the first to complete the initial network assessments and we are delighted that they have achieved compliancy. This neatly illustrates the growing momentum within the Wi-Fi roaming ecosystem, paving the way for the continued implementation of Next Generation Hotspot (NGH).”

About Hetnets Tower Corporation
In early 2013, we formed a wholly owned subsidiary, Hetnets Tower Corporation (“Hetnets”). Since 2010, the Company has been exploring opportunities to leverage our fixed wireless network in urban markets to provide other wireless technology solutions and services. Over the past few years, a significant increase in mobile data generated by smartphones, tablets, and other devices has placed tremendous demand on the networks of the carriers. The Company believes that the wireless communications industry is experiencing a fundamental shift from its current, macro-cellular architecture to hyper-densified Small Cell architecture where existing cell sites will be supplemented by many smaller base stations operating near street level. The Company also believes that Wi-Fi will be an integral component of Small Cell architecture.

We have effectively transferred certain assets to Hetnets which is the operating entity for our shared wireless infrastructure segment. Hetnets plans to generate the majority of its revenue from (i) rental of space on street level rooftops for the installation of customer owned Small Cells which includes Wi-Fi antennae, DAS, and Metro and Pico cells, (ii) rental of a channel on Hetnets’ Wi-Fi network for the offloading of mobile data, (iii) rental of cabinets, switch ports, interconnection services, including backhaul or transport, and (iv) rental of power and power backup.
