    Anatomy of a Sprint Triband Hexadecaport (16 port) Antenna Setup

    Thanks. Informative video in the link.

    Anatomy of a Sprint Triband Hexadecaport (16 port) Antenna Setup

    Is this setup a prelude to massive MIMO in that they would add multiple antennas/RRUs to get to the 64T64R or will there be hexecontatetraport (64 port ) setup at some point?

    Recent (12/2017) Japan roaming experience

    Calls are $ .20/min (free on wifi), texts are free and as far as I know there isn't a limitation on data. It's somewhat confusing given the $5/Month Japan roaming option. It would appear that the roaming option would net you free voice calls and not sure what else.

    Recent (12/2017) Japan roaming experience

    I would have purchased the high speed data as my company would have reimbursed me for the charge. I do think that with AT&T and VZW doing the $10/day to use home rate plan undercuts the value of the $5/day or $25/week offerings from Sprint (and I think T-Mo). As it was, I used about 850Mb of data (mainly for the speed tests) while I was there. The other nice service was Wi-fi calling. I was on a boatload of conference calls back to the U.S. and as of today I had one minute ($.20) of international calling. That was probably more valuable than the high speed data in my case.

    Thanks for the reminder. I forgot about the fact that the connection is a quasi VPN back to Sprint and therefore pings suffer.

    I'll try that.

    I have the speedtest screen shots but am not able to upload due to size. To save you the agony of knowing the speeds: Test 1: Tokyo 6:16am: Ping 347ms; DL 18.2Mbps UL 18.31Mbps Test 2: 8:54am Haneda Airport: Ping 358ms; DL: 48.05Mbps; UL: 24.01Mbps Test 3: 5:48AM Tokyo: Ping: 328; DL29.35; UL19.32
  9. I just returned from a business trip to Japan and have some interesting things to report regarding Sprint international roaming on SoftBank. I'm a BYOD customer (aka 1 year free) and therefore my expectations were that I would receive throttled (2G speed data) with the option to purchase 'high speed' data on a daily or weekly basis as needed. On landing and turning on my phone, I received the usual SMS messages welcoming me to Japan and noting rates for calls and texts. However, I also received a message "High-speed data included at no additional cost on this trip!" Hmm... exciting. My trip kept me in downtown Tokyo with a diversion to Yokohama for lunch one day. I definitely did not venture outside urban areas and therefore my experience is not representative as a testimony for the network throughout Japan. In both cities I can attest the network is very dense and I don't recall having a low signal situation anywhere. I was able to use the service just as I use Sprint in the U.S. On my iPhone 6, the hotspot worked great and the speeds were excellent. Towards the end of my trip, I did some speedtests (photos attached) at my hotel and at Haneda airport, connecting to Band 1 and 3. I never did see an instance where I connected to band 41 (but then again I don't have the benefit of SCP and wasn't running around with the field test mode going all the time). I was surprised at the ping times and played around with the servers on speedtest to try and see if there were any changes (nothing) and as you can see whether it was band 1 or 3, downtown Tokyo or the airport, pings were consistently in the ~300ms range (by way of reference the hotel wifi was ~4ms (assume fiber)). Overall it was impressive and considering the usual cost of roaming, the experience was excellent.

    The Magic Box 6 months later

    Is the doubling of the ping time coincidence or a consequence of using the Magic Box?

    iPhone 8, 8+, X announced

    Thanks. That might be it. I noticed this morning that PhoneScoop lists the FCC ID's as BCG-E3161A and BCG-E3175A. Clicking the hyperlink to the FCC's website returns a not found error. I was able to find a couple of variants of the iPhone 8, including Model NumberA1897 (no CDMA) and (BCG-E3160) Model Number A1864 (CDMA) /A1899 (same test report).

    iPhone 8, 8+, X announced

    I'm struggling to find the filings on the FCC's OET website for the iPhone X. I've attempted to search under Grantee Code (BCG) and what I think is the Product Code A1865. I've also scanned through every filing with a Final Action Date of today, looking for listings with lower / upper frequency ranges that correspond to B41. It appears that they've changed the naming convention of the suffix of the FCC IDs which makes it more challenging: Some are BCG-(Apple Model Number); Some are BCG-ExxxxA. Can anyone please lead me to the filing for the iPhone X? Thank you

    HPUE in iPhone 7s/7s Plus/8?

    I could well be incorrect with my logic but given that the iPhone 6 and 6S (and I assume the 7 has and the 7S will continue this trend) both had Band 41 EIRP levels that were >26dBm (HPUE Power Class 2), is it really a relevant point as to whether the iPhone 7S has or doesn't have HPUE? It appears that the iPhone is already providing band 41 uplink performance that is superior to HPUE through positive antenna gain.
  14. Exciting news in all respects and thanks to Robert for bringing this to light, especially the project details (that are lacking in the FW story). My takeaway is that network expansion will be done to largely accomplish 2 things: comply with buildout requirements (as AJ has noted in past reports) and, as Robert's story reports, eliminate roaming costs in strategic areas. While I hope that they eliminate some 'bad actors' (i.e. Swiftel as Robert mentions and nTelos as others have commented on), I believe that capital constraints will economically restrict what they can to and Masa's commitments to work with CCA/RRRP program will politically limit what they can do. (as an aside, I'll be intently looking for statements from Sprint on how these efforts reconcile with the CCA/RRRP program and hope that they have a very synergistic message regarding their expansion and continued commitment to working with smaller carriers in rural areas.) The other interesting point that could be debated in this announcement is whether these actions signal any sentiment on the probability of the 600MHz auction. I feel that the buildout requirements and the inevitable delays in the auction are driving action more than anything but it could be seen as pessimism that the 600MHz auction will occur, that Sprint will participate, or that Sprint will have the economic means to garner a significant enough portion of spectrum to make a difference. The balance of the effort in my opinion really comes down to service reliability through densification: adding sites to make the LTE airlink and Sprint's band classes work with PCS/CDMA site spacing. While that's certainly important (especially for RootMetrics, et al, rankings), I'm more keen on Sprint achieving overall network size parity with the duopoly. Overall, its a continuation of the 'build it and they will come' strategy. Unfortunately, there are 4 companies building ballparks in cornfields right now. I just hope that Sprint's field is [insert your favorite MLB ballpark analogue here], not my neighborhood vacant lot where kids play stickball.

    T-Mobile LTE & Network Discussion

    Thanks for the replies to moderate my cynicism. I really have a hard time believing that T-Mobile will be able to meet their timelines if they follow a similar development path to what Sprint has done. We know the challenges in getting new backhaul in place (microwave is certainly one way to reduce this risk and as mentioned seems to be key). We know that permitting takes time. We know there are unforeseen supply chain events that affect hardware deliveries. There's weather and crew availability. It just seems that with all of those pacing items/contingencies causing potential schedule risk. The other challenge is likely that going from 260ish M POPs to 300M POPs will likely require far more than a linear/proportional number of cell sites. So I assume that they're going to have to find space on a bunch of new sites simply to expand the footprint. I guess my mind just drifts to 'slap up some panels to replace what's there' (don't change the number or general physical shape to facilitate an easy permitting process), keep the existing backhaul (so you don't have to worry about backhaul driving LTE availability), and market the crap out of your urban/exurban speeds. Voila, a Nation-wide LTE network. That said, I hope they do meet their POP target with a legitimate, sufficiently dense LTE network as I think that is key to creating a competitive alternative to the duopoly. Now if Sprint would take some of that 'Google balloon technology' and cover the Dakotas with a 3 or 4 balloons' worth of 25/26/41, we'd really have something interesting (I make no claims to the technical merits or feasibility of this idea). lol
