LTE-B, LTE-C, ... , LTE-X
Please make sure to read the comment from Kevin Flynn of 3GPP at the end
When I saw this picture above, I started wondering what LTE-B, etc. and started digging a bit deep. Came across this Ericsson presentation (embedded below) that shows the breakdown.
To just be sure that this is not Ericsson specific term, I also found a presentation by NTT Docomo (embedded below)
So I guess using LTE-B, LTE-C, etc. is better than saying 4.1G, 4.2G, etc. as we did in case of 3G/HSPA.
The presentations from Ericsson and NTT Docomo embedded below, available to download from Slideshare.

High level view on how SMS works in LTE
The following is from E\\\ whitepaper available here:
In 2010, 6.9 trillion text messages were sent globally and this figure is expected to break the eight trillion mark in 2011. This represents USD 127 billion in revenue for operators. LTE provides the same basic SMS features, such as concatenated SMS, delivery notification and configuration. However, the SMS delivery mechanism is somewhat different. A VoLTE device can send and receive text messages encapsulated within a SIP message. To receive a text message, the encapsulation process is invoked by an IP short-message-gateway in the IMS domain, and the gateway converts traditional Signaling System Number 7 (SS7) Mobile Application Part (MAP) signaling to IP/SIP.
To ensure that text messages are routed via the gateway, the home location register (HLR) of the recipient needs an additional function to return a routable gateway address back to the SMS-C on receipt of an SMS-routing request.
When a VoLTE device sends a text message, it should perform the encapsulation. The gateway extracts the text message inside a SIP MESSAGE signal before passing it on to the SMS-C.
However, if the VoLTE device is configured to not invoke SMS over IP networks, text messages can be sent and received over LTE without the need for any SIP encapsulation. A received text message will reach the mobile switching center server (MSC-S) of the mobile softswitch system in the same way as it does today. The MSC-S will page the device via the SGs interface with the Mobile Management Entity (MME) of the EPC system. Once a paging response is received, the MSC-S will pass the SMS on to the MME, which in turn tunnels it onto the device. Due to the support for SMS delivery and IP connectivity provided by LTE/EPC, MMS works seamlessly.
For more technically minded people, there is a whitepaper that covers SMS in detail available here.

Ericsson Video: Using LTE to broadcast Danish elections
Danes elected a new parliament September 15. As four teams from TV 2 moved between party headquarters, Parliament House and celebration sites, they used standard off-the-shelf LTE terminals to upload interviews to the tv-station, which in turn broadcast the content live to viewers on their channel.
The solution is provided by operator TDC, on the network supplied and managed by Ericsson.

HD Voice - Next step in the evolution of voice communication
Nearly 2 years back I blogged about Orange launching HD Voice via the use of AMR-WB (wideband) codecs. HD voice is already fully developed and standardized technology and has so far been deployed on 32 networks in almost as many countries.
For more information also see:
People who have experienced HD voice say it feels like they are talking to a person in the same room. Operators derive 70 percent of their revenue from voice and voice-related services, and studies show that subscribers appreciate the personal nature of voice communication, saying it offers a familiar and emotional connection to another person.
HD voice is also a reaction to the competition faced by the operators from OTT players like Skype.
Below is an embed from the recent whitepaper by Ericsson:

Benefit of 1.4GHz for Mobile Downlink
Significant benefits could flow from use of 1.4 GHz band for a supplemental mobile downlink for enhanced multi-media and broadband services, according to a study by Plum Consulting conducted for Ericsson and Qualcomm.
The band is currently allocated for use by digital audio broadcasting (DAB) services in most European countries -- part of the band is allocated to terrestrial networks and part is allocated to satellite networks. None of these services have developed in the band. Rather in all countries in Europe the satellite part of the band is unused and this is also the case in the terrestrial component in most countries.
There could be up to eight times as much data being downloaded than is being uploaded in mobile networks. This imbalance is expected to grow, as rich mobile content is increasingly made available and as consumer demand continues to soar. The study found that the use of the 1.4 GHz band as a supplemental downlink band for mobile applications is shown to drastically ease capacity, to enable considerably higher user data rates, to substantially enhance the user experience and to provide significant economic benefits.
The value of releasing the 1.4 GHz band depends on whether other substitute spectrum may become available in the next 5 to 10 years. Starting from today, all countries in Europe have planned or are planning to release the 800 MHz and 2.6 GHz bands in the next two years. There is equipment available for use in both bands and services are already deployed in some countries.
Which other bands might be released over the next 10-15 years? Table 3-2 gives a number of candidate bands, ordered by the likely timing for release, including the 1.4 GHz band for completeness. In each case, we summarise the current status of the band, initiatives that suggest it might be a candidate for future release and our views on the possible timing of deployment based on the difficulty of clearing the band and the harmonisation/standardisation initiatives that would need to be undertaken before equipment would be mass produced for the band.

Advanced Telephony Services for LTE
With LTE World Summit just round the corner, I was going through the last year's presentations and realised that we didn't talk of this one before.
The concept for the advanced telephony services has been around since the early days of IMS and this was one of the ways IMS was sold. Unfortunately IMS didn't take off as planned and only now with the standardisation of VoLTE, there is a possibility of the advanced services becoming a reality.
The following presentation summarises some of these advanced telephony services concepts.

More than 50 Billion Connected Devices
I blogged about the 50 Billion connected devices as predicted by Ericsson last year. With the promised 'Internet of things' and 'connected world' we may see 50 billion devices not too far in the near future. Here is a recent whitepaper from Ericsson on this topic.

Making small purchases simpler with Ericsson IPX
Yesterday a colleague made me aware of this Ericsson's IPX SMS based payment system that looks like a competitor to the NFC technology and doesn't involve any additional chip/hardware. Here is a video:
From Ericsson's website:
Ericsson Internet Payment Exchange (IPX) is a leading mobile aggregator, providing delivery and billing services, via SMS, MMS, web and online mobile billing, to more than 2 billion mobile subscribers across 26 countries. Ericsson IPX also brokers location information in selected countries and Ericsson IPX Messaging provides reach to 96% of all mobile subscribers worldwide with SMS. Ericsson IPX customers are companies who offer digital content, mobile voting & directory information and enterprises offering mobile marketing, communities and banking.
Now, we all love SMS and we have to admit that its the simplest of technology and even the most primitive phone nowadays support it but there could be scenarios when this can be a bit of a problem:
1. SMS can sometimes be delayed if a particular cell is overloaded, etc. So how long do we have to stand in front of the machine?
2. If say for 2-3 mins we do not receive an indication that the machine has a cash, do we send another SMS to cancel the transaction?
3. If we have a problem, do we have a support number to call to? How much will that cost?
4. If there is a queue of people and someone else wants to purchase something as well, does the next person has to wait till the person before has received the item?
5. If two people have sent an SMS, how do they know whose cash is in the machine now? Do we start putting a Pin as well ?
I agree, this technology could be really useful if you have run out of cash (even if you have NFC chip) and you need to purchase something small.
The other obvious advantage is that you can target advertisement at regular users who are at a particular place at a particular time to make them buy something. Also you can get statistics like what time people tend to purchase, what do they purchase, where, etc.
Anyway, hard for me to see this take off big time.
