Thought this wouldn't be something we'll see until LTE-Advanced started rolling out...

Korean carrier SK Telecom is hoping to push the limits of LTE speed by combining multiple frequencies in one network. At the beginning of July, it launched the first commercial Multi Carrier (MC) network, which combines frequencies from the 800MHz and 1.8GHz bands and distributes traffic between them as necessary, keeping service stable even during high use times. Currently, service is only available in Seoul's Gangnam district; the rest of the city and areas in six other metropolitan centers should see it by the end of the year, with more expansions to follow. A pilot program has been running since May.

We first heard about this project in January; although SK Telecom didn't give network speeds in its latest announcement, it previously said users would see 60Mbps download speeds this year and 100Mbps by 2013. Phones that can support the system, meanwhile, are apparently coming soon. The Pantech Vega Racer 2 and Samsung Galaxy S III are getting a firmware update that will make them compatible later this month, and "most" smartphones released in the second half of 2012 should have support built in.

Is this the future of 5G?

 

No. SK Telecom is simply running in parallel an LTE 850/1800 network, much like Sprint will be running in parallel an LTE 800/1900 network.

I can't believe Broadcom is already talking about 5G WiFi.

That's just marketers creaming themselves. There was no 4G or 3G WiFi. It's just hype.

I hate to imagine what might happen if thelasthallow finds out about this 5G Wi-Fi.

There aren't even benchmarks set for 5G...

 

The hype machine is rolling full bore.

 

I thought 5g was set for 1gbs

I thought that 800MHz was just for propagation and deep indoor service where 1900MHz isn't available.

Traffic distribution over different frequencies is a part of NV?

Yes, Sprint will use 800MHz for capacity too. However, LTE 1900 will be a higher usage carrier. 800 will just be for shedding users when 1900 is nearing capacity, and of course for users outside of 1900 range (like in basements, bunkers and edge of service areas).

I assumed that this whole "World's First" was that this would load balance(pilot) devices between 800 & 1800 has needed. I understand that(Sprint) has capacity on 800MHz, but I thought that their intention is that your device would generally just be using what ever signal is usable(but higher; 2500>1900>800).

Because Clearwire and Sprint's deal for LTE is usage based, the order will most likely be 1900 > 800 > 2600.

 

They will not allow the 800 carrier get to 100% usage, so users will likely get shunted over to 2600 before the carrier starts getting full. LTE network management allows a lot more controls than CDMA and EcIo ratios.

I see. As for Clearwire, their LTE would only be available in "Hot Zones", where more likely than not, Sprint will run into capacity issues(outside of small cells), so this should really be a money maker for Clear.

Once NV is done and Sprint is profitable, clearwire needs to be absorbed so that 2600mhz can be the priority in the densely populated, urban areas where these hot spots will exist.

      Network Vision/LTE - New York City Market

      By Paynefanbro · Posted

      As far as I know it's ubiquitous. Ultimately the network decides if you should use VoNR vs VoLTE but pretty much anytime my phone is in standalone mode and I place a call, it goes over NR.   Yup, it was terrible. After a while, I just connected to the WiFi, and that worked fine at about 90Mbps. I get the feeling that rather than doing a "real" upgrade where they install new antennas, upgrade backhaul, etc., T-Mobile instead installed new radios onto the existing and already overloaded DAS and called it a day, which isn't enough. Compared to Yankee Stadium, where they actually went and deployed new antennas/radios for their n41 upgrade, and you're able to get upwards of 200Mbps at sold-out games, Arthur Ashe really is a joke. What's worse is that the folks in their NOC likely know this already, but no effort is being made to change that. I'm not asking for T-Mobile to deploy mmWave everywhere like Verizon but there is a real use case for it at stadiums.

      Does anyone know how well implemented is VoNR in the 5 boroughs. Does anyone use it? I have an iPhone 15 Pro. Does anyone know if T-Mobile is still working on upgrading their network? It seems like the service has gone down. My phone struggles in parts of the Belt Pkwy, and data is slow.

      I come to the US Open men’s semifinals and finals every year, and I’ve never been able to use my T-Mobile phone successfully. Usually AT&T is the top performer—good to hear Verizon has upped their game.

      One sector down, two more to go — — — — —  I was at Arthur Ashe Stadium for the U.S. Open today and the good news is that there is an n25/41 DAS setup throughout USTA Billie Jean King National Tennis Center. From the "boardwalk" to the outdoor concession area, to inside the stadium; you connect to standalone n41 and n25 everywhere via oDAS and iDAS. The bad news is that in the actual stadium it's beyond useless. While I saw strong coverage as indicated by signal bars and I was able to make calls and send texts, there was no data throughput at all. Running a speed test failed 9 out of 10 times. The only time I got a speed test to work was by switching to LTE funnily enough or by using NSA 5G where the test would initiate via LTE and then n41 would kick in giving me ~20Mbps. T-Mobile has so much traffic on their 5G network that now n41 gets bogged down before LTE. That was a first for me! In the stadium in the same area Verizon got 1.2Gbps on mmWave and LTE kept timing out when trying to test it. My Boost line on AT&T got upwards of 150Mbps on C-band and I know they have mmWave deployed as I saw their Nokia mmWave antennas deployed but I was unable to test it. In the outdoor concession area T-Mobile performed well getting over 150Mbps on n41. AT&T in these areas saw over 250Mbps on C-band and I didn't get the opportunity to test Verizon there. It just seems like 140MHz n41 is not enough capacity for the amount of people inside the stadium. Hopefully T-Mobile is considering deploying n258 to all of these stadiums since they now own that mmWave nationwide. It'd make a world of difference in terms of capacity at these venues.
