Review: Point-to-Point Systems: Page 9 of 15

Both the Tsunami.GX 90 and the Tsunami.GX 200 did well in our performance tests. Throughput for the GX 90 ranged from 85 Mbps to 88 Mbps, whereas the GX 200 ranged from 169 Mbps to 175 Mbps, depending on the attenuation level and modulation scheme used. Both products provided sub-millisecond latency (0.8 ms for the GX 90 and .058 ms for the GX 200) in our tests. Proxim told us is sees sub-millisecond latency in real-world deployments as well.

Organizations that want true full-duplex performance--for extensive voice applications, for instance--and have devices on hand to provide QoS, will find the Tsunami.GX-series radios good performers. However, they're also the highest priced entries, at $19,998 per pair for the GX 90 and $29,998 for the GX 200.

Proxim Tsunami MP.11

The Tsunami MP.11 is, technically, a point-to-multipoint system, however Proxim shipped it to us to demonstrate the functionality of its entry-level QuickBridge.11, which includes only integrated antennas.

Besides one issue where the radios were unable to transmit traffic sent on VLAN ID 1, the MP.11 is a respectable entry-level fixed wireless system. Throughput averaged 23 Mbps, and latency was higher than other products we tested, with values ranging from 13 ms to 14 ms. We were pleased that QoS options are plentiful, with 802.1P, DSCP and ToS supported in the radio and performing as expected in our QoS testing.
