What does LTE Advanced Pro Promise us?

LTE Pro will be an "intermediate" standard before the wireless industry continues with "Release 15" in 2020 and beyond, also known as 5G technology. LTE Advanced Pro is essential Rel 13/14. Below is what LTE Advanced Pro will deliver.

Carrier Aggregation
Delivering fiber-like speeds by using Carrier Aggregation (introduced with "LTE Advanced" networks in 2013) to aggregate more carriers, and to use simultaneous connections to different cell types for higher spectral efficiency

LAA
In short, Licensed Assisted Access (LAA) is the 3GPP's effort to standardize LTE use inside of 5GHz WiFi spectrum. It was introduced in 2015 and allows mobile users to simultaneously use both licensed and unlicensed spectrum bands at the same time. 

Full Dimension MIMO
This technology uses elevation beamforming by using a 2D antenna signal array in order to exploit 3D beamforming. Later down the road in 3GPP Releases 14 and beyond, we can expect support for higher-order "Massive MIMO."

LTE IoT
Includes enhanced power-save modes (extended DRX sleep cycles) for small devices. More importantly, this also means beyond 10 years of battery life for certain small device use cases.

"Vehicle-to-Everything" Communications, or V2X
Integrating LTE into the connected cars of the future. The goal is to connect cars at higher-than-gigabit LTE Advanced Pro speeds to one another, and to also connect them with nearby pedestrians and IoT-connected objects in the world around them.

Converged digital TV
This means television broadcasts over LTE to multiple devices, simultaneously – basically, an always-on LTE Advanced Pro TV broadcast stream to 4K home televisions, tablets and smartphones for the whole family

LTE Direct
LTE-Advanced Pro's capability for proximity sensing – without the use of GPS – autonomously. This includes using upgraded cell towers for knowing when friends are nearby and for discovering retail services and events, all without triggering WiFi or GPS modules on your device.

LTE Emergency Safety System
It will deliver both terrestrial emergency information as well as automotive road hazard information. Using phones for push-to-talk systems on walkie-talkies.

What is Skylake and how does it compare with Broadwell or Haswell?

Haswell, Broadwell and Skylake are are codenames for the respective 4th, 5th and 6th Generation iterations of Intel's processor microarchitechture. Broadwell is perceived as a version upgrade from Haswell however Sklyake is a major microarchitecture re-design. Apple has introduced the latest lineup of Laptops that now use Intel Core M processors based on Skylake. Core i5/i7 are faster than Core M. Core M lies in between the ATOM and the Core i5/i7 series but on a Skylake Architecture however. Intel has the Core i5/i7 versions on both Skylake and Broadwell.

What is three in a box model?

IT Companies in India are now having one of the three senior executives designated as a 'client partner' and there will also be a 'delivery partner' based in India to ensure that work commitments are adhered to. In addition they will have a consulting partner as well.   "The key objective of the consulting partner programme is to help provide greater strategic value to the client organisation by proactively solving clients' business issues, demonstrating domain or functional knowledge and innovation, delivering higher-value strategic and transformational projects," R Chandrasekaran, group chief executive for technology and operations at Cognizant, wrote in an email.   The full article is at http://articles.economictimes.indiatimes.com/2012-09-21/news/34002564_1_infosys-clients-information-technology-bellwether
