    How? I haven't found a way to force the desktop version on mobile. Selecting "request desktop site" in Chrome just reloads the mobile version. Sent from my Nexus 6

    In the SF market we've found 1 new B25 site that's presumably full build since it has 3 sectors (via SCP only, haven't found the exact physical location yet but have it narrowed down to a few blocks). We've also found a cluster of B41 small cells in an area where Clearwire had deployed WiMax small cells. Again, these have only been seen in SCP, no one has physically located them yet. They each only have 1 sector. Sent from my Nexus 6

    Ahh. That's a shame. I was looking forward to a capacity boost from another carrier on Clear sites. Sent from my Nexus 6

    Even once wimax is shut down? I thought the Huawei equipment could support multiple B41 carriers once they stop broadcasting WiMax? Sent from my Nexus 6

    Yeah B25 and B26 speeds here have improved lately. They've been tweaking the load balancing, especially within the last week. I've noticed I rarely idle on B26 anymore, and actually hang onto a weak (-112) B41 signal much more frequently. Frustratingly, the weak B41 is pretty much unusable (0.2 Mbit and times out a lot), but when it eventually kicks over to B25, or when I get a better B41 signal, it's great. 30 down on B41 is really good, I rarely see above 20 anymore even with 2 carriers on the site.

    In San Francisco (Samsung market) we have a mix of 03, 04, 05 and 09, 0A, 0B for the second B41 carrier. EARFCN is 40254. We won't have any Clear second carrier until after the WiMax shutdown, so those GCI endings are still TBD. Sent from my Nexus 6

    Anyone have any idea why these cables are so expensive compared to even the premium monoprice micro USB cables? Sent from my Nexus 6

    That part of the BART DAS hasn't been upgraded yet unfortunately. The part south of the Glen Park station has been upgraded for a while though (B25 only). I'm not sure what the hold up is. Sent from my Nexus 6

    It works on Fi, so it must support Sprint. Sent from my Nexus 6

    Just drove past that site the other day and there aren't B41 antennas yet. I also figured I'd share some things from the Premier thread which I believe are OK to post here (mods please let me know otherwise): The first is that there appears to be a new site in Noe Valley, but we haven't been able to narrow down the location of site yet. The strongest signals from it are labeled "B" on this map of signals that don't match up to known sites. My guess is it's somewhere near Douglass Playground. If anyone is in that area and wants to try to track it down, I would happily accept Signal Check Pro logs and add them to the map. Or even better if you can find the site and get pictures. The second is that mc_gusto found that SF publishes a map of all wireless sites within the city. https://www.google.com/fusiontables/DataSource?docid=1jgD0NwaO_dLNhIkjaANj_2fzV9WFwLDGgb8uM57x#map:id=3 It hasn't been updated since April, so it doesn't help yet to identify the site mentioned above. But it's still a very useful resource and can be used to compare Sprint site locations with other carriers, amongst other things.

    I'm not certain it actually is. I can't find anything that confirms it, so I may be mistaken. My understanding though was that eCSFB and IMS were coupled together (maybe IMS sends the initial message to switch to CDMA?). The closest I could find was the last page of this thread http://www.s4gru.com/index.php?/topic/5001-Breaking-Band:-Tri-band-LTE-/-eCSFB-issues-thread Sent from my Nexus 6

    They actually do have IMS, it's used for SMS over LTE, and I believe it also plays a role in eCSFB. Sent from my Nexus 6

    I'm guessing it would be similar to what Clearwire's plans were for WiMAX http://www.senzafiliconsulting.com/LinkClick.aspx?fileticket=poRsDqBRr0I%3D&tabid=104&mid=466&forcedownload=true Sent from my Nexus 6

    I think it's more likely a local IMS server went down. I wonder if voice and text would have worked if in 3G only mode. Sent from my Nexus 6

    I believe Clearwire was doing this (or planned to do it) for Wimax, but it could have been restricted to their small cells. Sent from my Nexus 6
  17. ingenium
    So they have 2 antennas and are still running at least one in dual mode? Or are you referring to if they decide to add a second antenna to all sites for this? I would assume all high capacity sites have one antenna that's just LTE (and 4x2 MIMO) and another that's just CDMA? Sent from my Nexus 6

    I get that it is technically 3G according to the standards body, but OP was just being pedantic. EV-DO is "3G speed" and everyone here knows what is meant when someone says 3G vs 1x, especially in the context of roaming. Like it or not, 2G, 3G, and 4G have come to be associated with a certain level of speed and capacity, using each as a practical rather than technical definition. In the minds of most reasonable people, when they hear 2G they think 1x, EDGE, or GPRS; 3G they think EVDO, UMTS, or HSPA; 4G they think LTE. Especially in the context of roaming, the practical definition is implied, everyone knows what is meant by it. It annoys me to no end in fact that after the initial software release for the Nexus 6 they changed 1x to show as 3G next to the signal bars instead of actually showing 1x, because for all *practical* purposes 1x is not 3G (or what most would consider 3G speed). Anyway.... anyone have any luck figuring out how to manually write a PRL to the Nexus 6 yet?

    Please don't start this again. No one in their right mind would actually consider 1x to be 3G, despite what it technically may be. It has a max theoretical speed of 144 kbit, slightly faster than dialup. EDGE is considered 2G and is the same speed or faster. Sent from my Nexus 6

    That site is still B25/B26 last I checked (about a month ago). There are a few B41 sites in Berkeley, but most have limited range. For example, the one near Berkeley Bowl East doesn't even reach past the intersection of Ashby and Adeline (ie, 5 blocks). And it's mounted pretty high up, above the surrounding structures. So 0.3 miles sounds about right.

    Subtract (technically add) about 15-20 dbm to get the equivalent CDMA signal strength. So that's like a -92 or -87 CDMA signal, which is very usable. Sent from my Nexus 6

    What about sites that have 2 B25 carriers and a B26 carrier. Did they need a second antenna? Sent from my Nexus 6

    I managed to get ahold of a Clear WiMax USB stick. My quick testing with one site seems to indicate that the BSID is offset from the LTE GCI by 0x18800 (ignoring the last 2 digits). Side note, they apparently have thinned down to 10 Mhz carriers, with the sector I just connected to having a center frequency of 2673500 (equivalent to the second half of the TDD LTE carrier with EARFCN 41374). If they're still using different frequencies per sector, then they're using the last 30Mhz of Sprint's spectrum holdings. I'll be in that area in 2 weeks, I'll drive around and see if I pick up anything on my phone or on Clear. I'm curious how the WiMax BSID and center frequency will change between sectors and if groups of them indeed appear as a single site (ie, the same first 6 digits).

    Awesome find! So they're "pico cells" with fiber backhaul. That's why in some areas they're on every pole down the street (much more than the typical 3 sectors). Several are probably being lumped together as a "site". I hope Sprint can do B41 small cells the same way. It seems like it could be a quick rollout if so. Edit: Found one with what I think is an RRU https://goo.gl/maps/YlKJJ. It looks like it's "shoebox sized" like mentioned in the PDF. There's a panel on every pole down the street for several blocks.
  25. ingenium
    It's possible they're not, I don't have a WiMax device to test with. They're at every location that's a green dot on the map. I'm not sure where else they could put the panels at these locations since there aren't any other structures. I assumed they didn't convert them to LTE because they were different from the other Clear sites somehow and couldn't support it. Actually, looking around other areas that have green dots, some have panels on almost every pole. Could it be a DAS style setup? What's weird is that Clear deployed so densely in these mostly residential parts of SF, but sparsely in areas like downtown. I suppose it was built out as part of their home broadband plans? The density of the sites in these areas also leads me to suspect that they aren't normal builds.
