Graphisoft Park - Nonstop Wireless Access in the common areas of the exclusive office park

Graphisoft Park
Graphisoft Park is located directly next to the Danube, the beautiful river of the capital – in 18 acres
of green area. The designers and constructors of the office park were especially attentive to preserve
the nature and the green areas. Besides several smaller and middle sized companies, also Microsoft’s
and the European software giant, SAP’s international development’s base is leased here.
Biotechnological research laboratories can be founded in the Park as well; its first laboratory was built
for a Hungarian company named Comgenex, later acquired by the American AMRI. In 2007 there was
built a world-class research laboratory for the French pharmaceutical company, Servier. In Graphisoft
Park currently operates 60 companies with more than 2000 employees.

 

Challenge
The challenge was to provide fast and reliable Internet access for the workers and visitors of
Graphisoft Park all the time at as many places as possible for free of charge. All the buildings were
selected for deployment, where conferences, discussions can take place and where people can just
sit down for a while to relax and surf on the Internet. We planned the network system with focusing
on these areas. In the Park there are optical fibers among several buildings and we could also benefit
from these. Finally there were placed 8 ports PoE switches in the building B, C, K and N. The switches
are connected through a MSG3712F Metro Gigabit Ethernet Switch. Bearing in mind the survey
made by Equicom Ltd. we placed the NWA-3160 Wireless Dual Band Access Points. The APs operate in
control mode, so the management - which is in a separated VLAN - is mainteined with one single
IP-address.


We aimed to further enhance the utilization of the Park's grassy parts; we covered the area of the
little lake in the middle, the bar and the restaurant as well. So we chose a dual band outdoor device
for the top of the M building, from where the whole area mentioned above can be strewed. The
restaurant is located in one of the most frequented parts of the Graphisoft Park; we pursued to
ensure the Internet access here too. We established the connection on two floors, and place an AP on
the lower floor where the conference rooms are. The center of the system is in building C, as located
the hotspot gateway and the firewall ensuring the content filter is located here, as well as the
SNMP-based ENC server supervising the whole system operation. This device immediately generates
an alarm if any problem occurs in the network and continuously creates setting back-ups.
