7.3 Testing Throughput
The M10 family of products offers true 10 Mbps RF transmission.
However, the real measure of network performance is the average
throughput. This requires not only high-data-rate modem transmission, but
also efficient utilization of frame buffers and coordination of RF and wired-
interface traffic. The M10’s throughput is greater than or equal to 6.8 Mbps
with the re-transmission and 7.9 Mbps without the re-transmission under
the definition and specified measurement described below.
7.3.1 DEFINITION OF THROUGHPUT
The throughput of the M10 is defined as the average transmitted bits per
second from one M10 to another (as described in the following test
procedure).
7.3.2 SETUP FOR MEASURING THE THROUGHPUT
Figure 7.3.2 shows recommended setup for measuring the throughput. We
recommend characteristics for each device as follows:
• LAN analyzer-1: HP’s J2S22B or equivalent.
• LAN analyzer-2: HP’s J2S22B or equivalent or a PC with a
installed NIC and Novell’s “LANalyzer”.
• Hub: HP’s J2610A or equivalent. This works as a converter of
the interface from which the LAN analyzer has to the AUI. If the
LAN analyzer has an AUI port, then this hub is not required.
• Attenuator: HP’s 8494A (0 - 11dB; 1dB step) and 8496A (0 -
110dB; 10dB step) or equivalent. Two attenuators are connected
to provide wide variable range and precise adjustment.
