dailywireless.org » FCC Commissioner: Higher Power in Lower 5 GHz | LTE - Long Term Evolution | Scoop.it
DailyWireless.org covers current developments in broadband wireless, including WiMAX, LTE, WiFi and mobile aps. Online since 2002, with over 12,000 in-depth articles, we also cover social impact of 6 billion mobile users.
Eric Ponchel's insight:

As the LTE throughput seems to be lower in the US because of the mobile video growth (See Open signal results published at MWC '14), a new wireless alliance in the US is born in order to promote the unlicensed 5 Ghz spectrum as a way to "unload our Wifi connection" (WifiForward). A good channel to take a share of the 293 minutes of TV per person in the US.

Cisco Visual Networking Index: Global Mobile Data Traffic Forecast Update, 2013–2018

Cisco Visual Networking Index: Global Mobile Data Traffic Forecast Update, 2013–2018 | LTE - Long Term Evolution | Scoop.it
The Cisco Visual Networking Index (VNI) Global Mobile Data Traffic Forecast is part of an initiative to track and forecast the impact of visual networking on global networks.
Eric Ponchel's insight:

Many numbers to draw the profile of the future worldwide mobile consumption. One interesting input is in regards with the offload share (residential Wifi & public hotspots). Inded, while 4G will take half of the traffic over cellular, with only 15% of the connections, mobile offload will remain higher than cellular globally (4G/3G/2G), with 52% of the total mobile traffic. So, despite a strong growth, 4G does not cannibalize Wifi.

WBA: 22% of the mobile data capacity created in 2014 will come from Wi-Fi | LTE - Long Term Evolution | Scoop.it
We already dump a lot of mobile data traffic onto our home and office Wi-Fi networks, but in the next few years we’ll be tapping Wi-Fi in a lot more places thanks to new carrier networks.
Eric Ponchel's insight:

Beyond the title about the weight of public Wifi on wireless data, this study puts a light on the various alternatives at hands for the next capability improvements (new spectrum, LTE, small cells, CoMP,..). Obviously, the numbers will be subject to change depending on each learning curve for these technologies (See for instance my previous post about small cells). As opposed to the others, Wifi contribution seems notably stable around 20%.

Almost 600,000 base stations to be upgraded to LTE-A by 2018, says ABI Research

Almost 600,000 base stations to be upgraded to LTE-A by 2018, says ABI Research | LTE - Long Term Evolution | Scoop.it
Yota launched the first LTE-Advanced (LTE-A) network in Russia last October; however, with the first compatible handset, SK Telecom was the earliest to make the technology commercially available in June 2013.
Eric Ponchel's insight:

As per ABI predictions, there will be 600K eNodeB's supporting LTE-Advanced deployment in 2018. So what ? Is this good enough to absorb the explosion of wireless data in the coming years ?

 

Assuming that LTE-A can multiply by 4 the current LTE capacity, using a capacity model shared by NSN (see link below), it derives that 600K Base Stations would give a 4 billion users capacity - each consuming 5 GBytes monthly.... So, at first glance, this looks quite sufficient, right ?

SK Telecom develops LTE-A tri-band carrier aggregation technology » Telecoms.com | LTE - Long Term Evolution | Scoop.it
Eric Ponchel's insight:

This announcement reveals the level of flexibility required by LTE carriers to maximize their spectrum efficiency when facing peaks of broadband demand. Indeed, SKT recently acquired additional 1800 MHz spectrum but non-contiguous blocks (20+10 Mhz). This explains why a new Carrier Aggregation scheme with 3 Component Carriers (CC's) is needed to achieve this 40 MHz bandwidth (2 CC's in 1800 and 1 CC in 800 Mhz). This would be turned on when chipset & devices will be ready, hopefully end of 2014.

dailywireless.org » Apple TD-LTE Phones to China Mobile | LTE - Long Term Evolution | Scoop.it

"Apple and China Mobile will likely launch their TD-LTE phone on December 18 and may enjoy a significant boost in sales by offering iPhones that support TD-LTE. But low cost of 4G phones, according to Li Yue, China Mobile’s president, are expected to be priced below 1,000 yuan (US$162) and will appear in the second half of next year."

Eric Ponchel's insight:

As Apple and the various industry leaders are competing on TD-LTE to win market share with China Mobile, Qualcomm keeps dominating alone on the chipset market, with a forecast of 100 millions chips in 2016. Indeed, the other chipmakers struggle to deliver the main new LTE features for 2014, i.e carrier aggregation and LTE-TDD.

Eric Ponchel's insight:

Sharp analysis of what's going on for additional LTE features and their priority for operators. Small cells would come later - which is consistent with several earlier warnings saying that some key enablers are missing for the network densification (automated SON for HetNets, eICIC,.). Nevertheless, while the demand of network offload remains high, it looks to be just a question of timeline, 2016 as said in the article.

SK Telecom and Ericsson Realize Handover-Free Mobility

SK Telecom and Ericsson Realize Handover-Free Mobility | LTE - Long Term Evolution | Scoop.it
South Koreas SK Telecom says that it has successfully developed the worlds first technology that removes the need for inter-cell handover, the main cause of quality degradation in the small cell environment, in cooperation with Ericsson.
Eric Ponchel's insight:

As per the description of the handover free mechanism, it seems to mimic a "soft-handover" (as in WCDMA) by using the new transmission mode (TM9). This mode allows transmitting signals over 8 antenna ports (MIMO 8-layers) in a Multi-User configuration. This allows several base stations to send all together the same signal with 2 or 4 antennas (among the 8) to a mobile that receives a better signal. The other antennas of each base station can be used for other mobiles of their coverage.
