Diversity of
Underlying
Requirements
Diversity of the User Community
 SciWiNet resells cellular data services from Sprint. We are an Mobile Virtual
Network Operator (MVNO). We expect to also operate with T-Mobile in 4Q 2014.
 Usage model: a single bucket of data can be shared over any number of devices,
individual researchers can be given administrative access to their set of devices.
 The idea is to provide services and technology that can be used by the academic
research community
 Once fully operational
 User’s can bring their own devices (like Google’s Nexus 5)
 User’s sign up and register devices at the SciWiNet web site

 The goal of SciWiNet is to build wireless infrastructure that supports current and
emerging wireless requirements of the academic research community.
 Synergistic with GENI WiMAX….
 Extends the coverage for GENI researchers….
 Broadens the community…potential benefits of scale
GENI WiMAX/SciWiNet Demo
1. At Clemson, we have a GENI
WiMAX handset that has
access to SciWiNet
2. A student at Clemson will
move out of WiMAX coverage
and into Sprint’s network
3. The device is periodically
sending location, signal
strength and ping RTT data to
a server (a GENI VM)
4. We will show two live
visualizations: location/access
network, ping RTT time
series.
5. You can point your browser to
see the live map (http: point

Demo Wrap Up
• Objective for this portion of the demo- illustrate how
GENI/WiMAX experiments can be extended with coverage from
a commercial network
• GENI and SciWiNet :
• GENI/WiMAX handsets that are registered on SciWiNet can
work on:
• Sprint’s WiMAX and 3G network
• A yellow node or PCEngine box can use GENI WiMAX
dongles, SciWiNet LTE dongles, and WiFi
• As GENI Wireless evolves towards LTE, integration with
SciWiNet over Sprint’s LTE (and T-Mobile) will happen
• Our next demo will further show the exciting ‘connections’ that
are possible between GENI/Wireless and SciWiNet.
