ECV Wireless Benchmark Test 1
From LTWPwiki
Transfer speed test trials were run with a pair of Buffalo routers implementing a wireless distribution system (WDS). The image at right (click for blow-up) indicates the location of:
- main and secondary WDS routers (red points)
- benchmark test locations with notebook computer (numbered purple points)
- connection paths for wireless signals (red: WDS, purple: to endpoint)
[edit] Results
A 10 MB file was transfered from the host (simulated Internet) to the roving notebook in each test. Refer to aerial photo with location notations. Transfer speeds indicated were as follows:
- inside community room approx 20 feet from secondary router: 1.1 MB/s
- field north of community room: 1.2 MB/s
- farther north, around corder of building: 1 MB/s
- western corner of northernmost village building: .33 MB/s
- parking lot of northern building cluster, secondary LOS obscured by two buildings: no service
- near entrance to north cluester: .81 MB/s (off primary)
[edit] Summary
If we consider .1 MB/s (which is about 800Mb/s) as an acceptable service level, one can imagine attaining this coverage village-wide by positioning enough routers about ECV. The most aggressive plan I imagine based on this (Buffalo) device would use 3 primaries positioned at the perimeter of the main building on 3 channels with no frequency overlap, each working with two secondaries for a total of 9 boxes.
But we need to overcome the problem of signal loss caused by indoor positioning. This needs some more experimentation.
