 The
Torrent 7200 WTS
The Torrent 7200 WTS (WiMAX Test System) is designed to
comprehensively test 802.16e base stations, and builds on the
foundation established by the Torrent 7100
which was the world's first system for testing ASN gateways and
CSNs. It provides an entire WiMAX ecosystem which surrounds the base
station and can then be used to perform functional testing, load,
capacity, and performance testing. Although an entire WiMAX
ecosystem is provided, components can be swapped out for commercial
counterparts if desired; for example although we supply an ASN
gateway, you could use your own, but then still user our CSN.
The Torrent 7200 is based on scalable-OFDMA and is available in two
general varients; one which actually tests the airlink and one which
bypasses it entirely for cases in which MAC rather than MAC/PHY
testing is of interest.

As shown above, the Torrent 7220 actually consists of a suite of
products that work together in a unified manner to provide a
realistic, high performance, lineraly-scalable WiMAX test solution.
The central controller for the system is the Linux based CS-7200.
This server automatically configures, starts, and directs the
traffic servers in the system to run tests as directed by the user
through the UI-7200 GUI.
The MTS-7200 traffic server authentically simulates up to 500,000
mobiles and a single Linux machine. The ASN-7200 fully functional
ASN Gateway which supports R6, R3, and R4, while the CSN-7200
emulates the CSN (HA/AAA). Finally, the NTS-7200 provides a
comvenient aggregation of network servers (MMS, PoC, WAP, HTTP, FTP,
SMTP, etc.).
The key distinguishing aspect of the 7220 varient which will be
generally available this month (October 2007) is that it bypasses
the PHY and communicates with the base station directly by sending
MAC messages over Ethernet. For an online demo of the 7220, or
protocol interface details please contact sales or technical
support.
The Torrent 7230 communicates directly with the base station (or
base stations) using live air or via a baseband interface, thus the
key difference is the PHY which has the following specifications.
