Some time in the past 24 hours the signal to my neighborhood has dramatically improved! Turns out that Sprint finally changed the azimuth pattern on the cell site closest to where i live. Back in 2004 when the site was built it had a very well optimized coverage pattern. About 2 months after the site went live they decided to change the azimuth pattern (reason still unknown) to something that didn't make sense to me. As a result I lost coverage at home and so did most of the neighborhood. I filed numerous complaints about it to no avail. Well I was recently put in touch with a new Sprint engineer who had taken the place of a previous one. I wrote an e-mail describing the situation as well as a bad handoff issue that was happening in the area. Within one week he wrote back to me saying they had fixed the handoff issue. Turns out that they did! He also told me they had requested a site modification as well. So 2-3 months later they followed through with their promise and optimized the coverage pattern back to the way it originally was in 2004. With my Airave turned off I now get lower EC-IO readings as well as eliminated PN offset shuffling compared to what it normally was up until yesterday. Of course I really don't need this anymore because I have an Airave but I'm sure other customers in the area will be happy. Took 4 years but better late than never.
