Re: [WISPA] 3650 Deployment

[Matt Jenkins]

Through heavy foliage (4 miles and 20 oak trees), when using 3.65 vs 900 Motorola equipment I got better downlink but worse uplink. This was because the CPE is only 2x1 MIMO (has only one TX radio). I believe the use of a true 2x2 MIMO 3.65 CPE will perform better than most 900 systems in some environments. What I would really like to see is a FHSS MIMO 900 system that uses the whole band. With sync and coordinated hopping patterns this could outperform any system out there for foliage penetration and interference avoidance. Things to note: Clean noise floor on 3.65 and most connections were -82db to -88db receive. Noise floor in 900 was -75db so most connections would not link due to noise. 900 was single horizontal polarity. 3.65 was MIMO. 900 is limited to 4 watts EIRP. 3.65 is can use up to 10 watts EIRP in a 10mhz channel.
