According to Wikipedia, Dehring had Cassanova had some input in this new company. Seems odd though since those two were already focused on DISL (Ready TV)

There was a recent unsourced edit to the page (which added this) but I didn't bother to undo it since information the company is still slim.....

A most interesting discussion, However I personally am awaiting the day when 3GPP Release 13/14 is ratified and we start to see commercial rollouts in these categories. came across this article in March 2016 issue of IEEE communications magazine where they highlighted some of the items under consideration
"After the introduction of the 4G LTE-Advanced standard in 3GPP Rel-10, LTE-Advanced has continued to evolve through several releases and has become a global commercial success. The research community is now increasingly looking beyond 4G and into future 5G technologies, both in standardization bodies such as 3GPP and in research projects such as the EU FP7 METIS. ITU-R has recently finalized work on the “Vision” for 5G systems, which includes support for explosive growth of data traffic, support for massive numbers of machine type communication (MTC) devices, and support for mission critical and ultra-reliable and low latency communications [3].
While today's commercial 4G LTE-Advanced networks are mostly deployed in legacy cellular bands from 600 MHz to 3.5 GHz, recent technology advancements will allow 5G to utilize spectrum opportunities below 100 GHz, including existing cellular bands, new bands below 6 GHz, and new bands above 6 GHz, including the so-called mmWave bands. There are coordinated efforts across the world to identify these new spectrum opportunities. There were decisions for new spectrum below 6 GHz at the World Radio-communication Conference (WRC)-2015, and further decisions for new spectrum above 6 GHz are expected at WRC-2019."
Two of the most exciting enhancements in my mind are FDMIMO (Full Dimension MIMO) and enhancements to Carrier Aggregation:
FDMIMO
"FD-MIMO is one of the key candidate technologies considered for the evolution toward beyond 4th generation (B4G) and 5th generation (5G) cellular systems. The key idea behind FD-MIMO is to utilize a large number of antennas placed in a two-dimensional (2-D) antenna array panel to form narrow beams in both the horizontal and vertical directions. Such beam forming allows the enhanced NodeBs (eNB: 3GPP terminology for base station) to simultaneously transmit to multiple user equipment (UE: 3GPP terminology for mobile station) to realize high order multi-user spatial multiplexing.
3GPP has conducted several studies since December 2012 in an effort to provide specification support for FD-MIMO. The first step was a study item [4] for developing a new channel model for future evaluation of antenna technologies based on 2-D antenna array panels. The channel model provides the stochastic characteristics of a three-dimensional (3-D) wireless channel. Based on the new channel model, a follow-up study item [5] on FD-MIMO was initiated in September 2014 to evaluate the performance benefits of standard enhancements targeting the 2-D antenna array operation with up to 64 antenna ports over a standard-transparent approach such as vertical sectorization utilizing antenna elements in the vertical direction.
FD-MIMO has two important differentiating factors compared to MIMO technologies from previous LTE releases. First, the number of antennas can be increased beyond eight, e.g. to 64. As a result, FD-MIMO significantly improves beam forming and spatial user multiplexing capability. Second, specification support for FD-MIMO is targeted for antennas placed on a 2-D planar array. Using the 2D planar placement is also helpful in reducing the form factor of the antennas for practical applications".
Carrier Aggregation Enhancements
"As a natural approach for increasing the peak rate and improving the utilization efficiency of distributed frequency resources, carrier aggregation of up to five component carriers with common FDD or TDD duplexing was specified in Rel-10 to support a maximum combined bandwidth of 100 MHz. The combination of carrier aggregation and MIMO provides 3 Gb/s and 1.5 Gb/s peak rate on the downlink and the uplink, respectively. In Rel-12, carrier aggregation was extended to support aggregation of FDD carriers and TDD carriers, but the constraint of aggregating at most five carriers remained. This constraint limits commercial deployments, particularly considering the availability of the 5 GHz unlicensed band that can provide tens of 20 MHz carriers. Additionally, 3GPP is currently studying UE RF requirements for the introduction of CA with four downlink carriers, and it is expected that commercial needs would soon exceed the Rel-12 limitation of five downlink carriers.
Motivated by the above considerations, a new work item was approved for Rel-13 with the objective to specify CA operation for up to 32 carriers (or cells), which can support a peak rate of 25 Gb/s. The main specification impacts are on uplink control signaling and on the reduction of control channel decoding operations that a UE needs to perform. According to the Rel-12 design principle, the number of control channel decoding operations required for a UE increases almost linearly with the number of scheduling cells the UE can support. Rel-13 CA limits this increase by the eNB, essentially configuring the number of blind decoding operations a UE performs per carrier subject to a respective capability reported by the UE. The amount of uplink control information is increased to support HARQ-ACK information or channel state information for a large number of downlink carriers. Further, a UE can be configured to transmit the uplink control information on a secondary cell (SCell) in addition to the PCell to reduce the control signaling overhead of the PCell".
The article then goes into machine to machine communication discussing how LTE chips will be built into cars, appliances, home electronics, cameras, traffic lights etc.
"As a wide array of different sensing and positioning technologies (e.g. mmWave radar, video, and high-precision GNSS) become standard automotive features, one key V2X service is the timely and reliable delivery of critical messages to improve safety and traffic congestion. However, the exchange of these messages can be challenging due to a large variation in message sizes, strict end-to-end latency requirements, a potential range of several hundred meters, and support of high Doppler spread when, for example, two vehicles are directly approaching each other while each one is traveling at a speed of 140km/h (equivalent Doppler speed of 280 km/h).
LTE V2X is 3GPP's response to increasing market interest as well as increasing expectations that regulatory bodies worldwide consider technology requirements and potential mandates in the next few years for vehicle communication networks. For example, Korea, Japan, the EU, and the US have allocated frequency spectrum in the 5.8-5.9 GHz range for dedicated short range communications (DSRC) to support intelligent transportation systems (ITS). In China, CCSA has also conducted studies of the feasibility of providing vehicle safety services over LTE, and it is expected that the National Regulatory Authority in China will allocate dedicated frequency spectrum for V2X. It is envisioned that LTE V2X could be deployed on licensed or shared spectrum, and it supports operation outside of the infrastructure network coverage with technologies such as enhanced D2D communications".
Its sure is an exciting time to be alive to witness this transformation

Could be related to the "Bring the beat" campaign they've been doing since early this year.....

Alot of 5G's development reminds me of what the Cable & Broadband industry is doing with HFC. Heck, both DOCSIS 3.1 & LTE use similar modulation schemes as well and share OFDM (the air interface in LTE uses OFDMA & DOCSIS 3.1 uses OFDM). They're pretty much moving into the same direction. It's such an exciting time! To experience the move from basic CS data (i.e. GPRS) to mobile data speed exceeding most wired connections today.

whats that about, i'm overseas and havent heard about it

All Digicel markets sometime in February or March simultaneously changed their banners on Facebook & Twitter overnight to "Bring the Beat" banners featuring Shelly Ann and Usain....

Hah, cryptic much. Well, only 2 more days left

Possibly, they may be launching 4G LTE. My sources tell me they are a chinese company with a Jamaican management with some US$100 million in funding form the diaspora
