Google WiFi Continues to Be One of the Most Successful Wireless Broadband Networks in the World as It Celebrates Its Third Anniversary

Tropos-based Network has Adapted to Support Thousands of New iPhone Users and
Record-Breaking Traffic
SUNNYVALE, Calif.--(Business Wire)--
The Google wireless broadband network built with Tropos routers, in Mountain
View, California marks its third anniversary in August of this year and
continues to experience unprecedented usage. The steady growth trend was
outpaced in a recent 30-day period as the number of users jumped from 16,000 to
19,000, according to Google`s statistics. On a daily basis, the network now
transports close to 600 gigabytes of user data -- double the volume from just
two years ago. "We continue to experience extremely high demand - both in terms
of users and bandwidth," said Karl Garcia at Google, who leads the Google WiFi
project. "We`ve seen the iPhone and other Wi-Fi enabled handheld devices as
significant drivers of the high demand we see. Currently nearly a quarter of all
devices that connect to our network are handhelds, compared to almost none when
we launched the network," said Garcia.

"The launch of the iPhone significantly drove up network use; we`ve identified
4,000 unique iPhones on the network in just the last 30 days. We`ve seen the
iPhone and other Wi-Fi enabled handheld devices as significant drivers of the
high demand we see. Currently nearly a quarter of all devices that connect to
our network are handhelds, compared to almost none when we launched the
network," said Garcia. The growing trend for smartphone access of Wi-Fi networks
is similarly being experienced by AT&T who recently reported to AppleInsider
that 49 percent of users who connect to their Wi-Fi network are using a
smartphone.

The coverage area of Google WiFi is approximately 12 square miles and
incorporates business and residential areas. The high performance broadband
network is accessible to the community and visitors free of charge; all they
need is a Wi-Fi enabled device and a Google account. "The Google WiFi network is
a valuable community resource and helps increase economic development by making
it easy for residents and visitors to stay connected anywhere around town," said
Margaret Abe-Koba, mayor of Mountain View. "We are very pleased that Google
continues to support our community with this robust service."

The Google WiFi network has managed to keep pace with the doubling in bandwidth
demand without major hardware upgrades. Instead, most of the increases in
capacity have been due to innovations in the Tropos software and new, patented
algorithms to coordinate and manage radio spectrum resources. These include
PowerCurve, which adjusts the power and bit rate of each packet; Airtime
Congestion Control, which senses congestion and allocates resources fairly; and
Smart Channel, which maximizes spectral reuse and avoids interference. These
three patent-pending technologies enable far more efficient use of radio
resources than before, typically quadrupling the data capacity for the same
swath of spectrum. Tropos continues to be a wireless broadband market leader
with its proven technology and ongoing innovations which make customers`
networks faster, smarter, and more reliable.

"The volume of data and number of users on the Google WiFi network in Mountain
View is unmatched compared to other similar networks anywhere in the world,"
said Tom Ayers, president and CEO of Tropos Networks. "We continue to work
closely with Google to extend Tropos' technology leadership and continue to
solve the unique and challenging issues that outdoor wireless broadband
presents."
