LTE and WiFi to co-exist.

Telecom - You need to decide whether you’d prefer to have a super-sharp screen or killer battery life. The Lenovo Yoga 920 lasts hours longer than the HP, and performs better in benchmarks and games with the same CPU (although if this is thanks to the Meltdown vulnerability, the playing field is effectively levelled). lasvegas, well we have collected a lot of data from the field directly and from many other blogs so very complete his discussion here about Telecom, on this blog we also have to provide the latest automotive information from all the brands associated with the automobile. ok please continue reading:

August 12 2015: Wireless hunger for high speed services has surged rapidly due to the increase in multimedia content esp. video on the go and use of devices (other than mobile) that demand internet connectivity. True 4G cells even seems to be inadequate for the hotspot area in future. Small cells and Wifi offloading are some of the ways to cater the increasing indoor mobile data in those hotspot areas. Due to the limitation in speed of Wifi and finite spectrum in the cells in those areas, throughput is always limited to an extent. The discussion for the assignment of unlicensed spectrum to the later version of LTE is fierce and currently the talk of the hour in the wireless industry and research, which is termed as LTE-U (Unlicensed) or LAA LTE (License Assisted Access). It is also a part of the 3GPP Rel. 13 (under standard setting process) that is expected in 2016.

As large amount of bandwidth is available in 5 GHz ISM band, 3GPP and several other wireless stakeholders believes that LTE in unlicensed spectrum can meet the future data demands whereas there are some opponents (including WiFi alliance, Comcast, NCTA) who have serious reservation over the co-existence of LAA and WiFi in the same 5 GHz spectrum due to the interference. Listen Before Talk (LBT) mechanism or Clean channel selection algorithm has been devised to assign clean channels to LTE (due to other nearby LTE-U node and WiFi) but the opponents argue of not clearing out proper details about the sharing approaches and the collaboration with IEEE would have been more effective for proper standardization (Globally). 

Implementation scenario could be like the LA carrier aggregation of the Primary cell, established using licensed spectrum and co-located secondary cell using Unlicensed spectrum, with two options available for secondary cells: data either in downlink or both uplink and downlink.

Some even term LAA LTE as 4.5G LTE, which is the road to http://lasvegasin.blogspot.com /2014/04/5g-talk.html" style="background-color: white;">5G (see my old blog on this) for the enormous data demands not only from the mobiles but also from the censors, wearable and much more things which need internet to be connected (IoT). It is known that FCC will opt for technology neutral approach for those unlicensed band to make efficient use of valuable frequency spectrum for increasing consumer demand. As different countries/region have separate regulatory requirement for ISM band, more work need to spare for the formulation of unified, global Standard and proper coordination also be sought to answer the genuine concern raised by WiFi community. After some field trials, LAA is also going to be being applied commercially right away for selected regions in previous LTE versions with the software upgrade and the compatible radio units.

Nokia to acquire Alcatel Lucent

Telecom - You need to decide whether you’d prefer to have a super-sharp screen or killer battery life.

April 15, 2015: Nokia, the Finnish telecom OEM vendor is known to have finalized the buy out of France based another telecom OEM conglomerate Alcatel-Lucent at USD 16.6 billion. Both vendors have been struggling to have greater share in the world with rife competition from European Ericsson and Asian Huawei. Nokia, after buyout of all shares of the conglomerate NSN (Nokia Siemens Network) and sell out of their Mobile handset business to Microsoft, has been focused more on the technology development (specially 5G), telecom infra deals and growing Here Mapping service. 

The acquisition will make Nokia second in the global market share, some percentage lower than Ericsson and ahead of  Huawei. There were ups and downs of the share price of both company, once the news of talks rumor surfaced. Some analysts even claimed that the acquisition is to benefit Alcatel more than that of Nokia and some even argue that the merger of two weak players wont make a strong player. The deal (yet to be completed) is also seen by many as a daunting task since huge job cuts that is most likely after acquisition, might raise eyebrows of French Government/Politicians who are much conscious for job protection.

It is also found that Nokia is eyeing on the lucrative US market for internet routing and wireless industry that have high profitable margins. Nokia, the pioneer telecom vendor for GSM, and once a giant for handset has come down significantly over the years, due to challenges from cheap Chinese OEM in telecom and Samsung, Apple for Smartphone business. Let's see how will this acquisition culminate in coming days but one thing I am dead sure that my all time fav Nokia will certainly bounce back. Though I have not worked with any Nokia telecom equipment till now, I have big fancy love for the Nokia phones esp. Nokia 5800 Music Express (which is still with me unbroken and usable).
