Strix Systems Competitive Review of Firetide

1. Strix Systems Competitive Review of Firetide

2. Firetide Overview • Weakness • Firetide’s Linear mode can’t do mesh. • Their two radio backhaul is only for serial architectures only – e.g. along railways. • Having only two radios limits architecture design as they have no equivalent OWS 2400-30. • Firetide Bonded Mode turns their backhaul into a 1st generation single radio • Equivalent to our Turbo mode • HotPort 6000 is a backhaul solution only • HotPoint 4000 is an access solution only • General Description • HotPort 6000 series • 6201 single radio (2.4/4.9/5.8) - $2495+antennas • 6202 dual radio, single frequency band (2.4 or 4.9 or 5.8, can not mix frequency bands) - $2995+antennas • HotPoint 4000 series • 4600 outdoor unit single 2.4 GHz radio - $995+(2)antennas for diversity • 4500 indoor unit single 2.4 GHz radio - $695 (2) 5dBi antennas included • Strengths • Simple installation • Auto-discovery generates little traffic (vendor claim) • HotPort 6000 can bond two channels to achieve claimed 70 Mbps • But this will mean that only one radio for backhaul. Thus, throughput will be less than Strix after one hop and just get worse with more hops. Decrease by “1/N”. • 70 Mbps is theoretical – equivalent to saying Strix can do 35 Mbps, which theoretically we can, but not in the real world!!

3. Firetide overview (continued) • Additional weaknesses • Back-to-back HotPort 6000 and HotPoint 4000 is required to equal an OWS 2400-20 functionality. • Because each device is special purpose backhaul (6000) or access (4000). They must be connected via Ethernet cable. • High priced antennas ($495/omni antenna, $995/sector antenna) • Firetide radio receiver sensitivity is less than Strix’s • No Modularity • Fixed units only.

6. 3rd Generation Mesh for Strix – linear network for Firetide No latency imposed by busy radios • Strix’s 3rd Generation Mesh enables “full duplex” performance • Dedicated radio for client access • Dedicated radios for backhaul enabling full-duplex performance • e.g. one for dedicated “receive” and one for “transmit” • Near-zero throughput loss per hop with minimal latency • Self-discovering/Self-configuring/Self-tuning/Self-healing. • Firetide’s two-radio backhaul enables linear backhaul. However, in the picture below any node with more than two blue lines is not easily achieved by Firetide. • Firetide only advertises a linear design – for example along a railway system.

10. Independent Test By Iometrix Labs Strix and Firetide

11. Independent Performance Test Iometrix’ Industry-first Wireless Mesh Test Revokes Widely Accepted Law “It’s not every day that a test produces data that reverses a widely accepted belief: Effective throughput on wireless mesh networks is supposed to taper off to little more than 7 Mbps when traffic is backhauled over four or more nodes. In Iometrix’ first-ever series of independent IEEE 802.11 mesh tests, Strix Systems showed that their outdoor hardened OWS 2400 nodes spiked with multiple radios raise that bar fivefold to a steady 35 Mbps.” “Invitations to participate in this pioneering test were broadly distributed to vendors. But no more than half a dozen companies responded, amongst which Tropos who declined to submit their single radio solution citing reservations about our methodology, and SkyPilot who said they were unable to free up resources for this project. Only BelAir, Firetide and Strix Systems announced their intent to participate, but in the end, only the latter two stepped up to the plate. BelAir, in an about-face over a month into the preparatory phase of testing, withdrew its participation citing resource constraints.”
