"Korea's SK Telecom launches multi-frequency network for more stable LTE"

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.

    • Just revisiting the RCS issue and discussing another point I find odd.  Yeah, my family and close friends and most coworkers still mostly use whats app in our chats due to the odd RCS issues.   Some have Apple phones, some Samsung.  But using Facebook Messenger or Whats App handily eliminates those issues.   But the other thing I find odd is how all the information out there states that to use the Smart View app to mirror your phone to your TV that your TV and your phone have to be on the same wifi network.  That is 100 percent untrue.  I've historically not had wifi at home and only use it in our common areas in our community or occasionally at work.  But primarily I just use my phone for everything and do not have wifi at home.  It's because I haven't needed it.  I've been using all my Samsung phones for the better part of a decade now as my entertainment center because it's simple, effective, portable and absolutely does not require a wifi connection for my TV in order to cast all the content from my phone.  I'm not sure why it is stated that it is required.  The two devices - as we all no doubt know - create a wifi direct connection between the two devices in order for smart view to work, however, no general wifi network is required at all.  Again, I've been enjoying the feature for close to a decade but I find it odd that they say that you need wifi at home to use it.  Samsung television sets, Roku TV sets, LG TV sets (I cast to all of them at work regularly, again, sans wifi) and TCL TVs are all compatible.  There are likely more but these are the ones that I regularly screen mirror to, again, without the two devices being on the same network (this is separate from the notion of creating a wifi direct connection between the 2 in order to enable the service). This is the sole reason I only buy Samsung phones.   I tried a Pixel device before the Pixel 8 (which was the first to allow display out via wired connection for streaming) but it simply did not offer the same feature.   I wonder why they say this.  It's interesting if nothing else.  
    • Yeah, I probably see it through a Washington/Oregon market lens. And maybe a little Nebraska too.  These are the only places I have monitored Tmo overlay of USC closely. Tmo has already added service on 80% of the same towers that were unique to USC just 5 years ago around here.  The 20% left are either too close to an existing Tmo site, or, probably already on Tmo's plans to collocation.  But there is one USC site on the beach where our family likes to go that I am dying for Tmo to add service.  There won't be a lot of new coverage added here. But I have not done really any review in other USC areas.  But I definitely think it's a good move. Robert
    • Found Ericsson C-band+DoD in Brooklyn. What tipped me off was when I mapped a new eNB in this area on Halloween but I didn't see any permits for a new site in the area and the sectors I mapped matched the existing site that was there. Drove by it today and sure enough it's an Ericsson C-band + DoD site, likely one of the first in the city.  This is eNB 110340, formerly eNB 115257. — — — — — Also a T-Mobile new build in Queens. The permit for this one was submitted last year as a replacement for another monopole that got demolished nearby. It must've only recently got installed because it was offline when I drove by it.
