/* Major companies for low cost IP for MIMO */
This report presents a brief summary about Dolcera's capabilities in working with standards, with LTE-MIMOas an example.A detailed The taxonomy which covers most of the important aspects of LTE is presented. A sample Also presented are examples of mapping patents to standards going to the standard by using detail of graphical analysis and patent ranking is presented. LTE related Analysis of IPR declarations made to ETSI , and non-ETSI documents are also shown.  '''uncovered by Dolcera Landscape Procedure'''* Background study - Background study is done with web search depending on the area of client interest.* Finding key player/inventors - Web search is carried out to find the products and technologies of key playersalso provided.* Patents Search -** Key patents search.** Prepared search queries using keywords and classification and finalized these in Micropat/Thompson.* Patents Classification - Classify all patents by creating taxonomy.* Specific analysis as required by client like SWOT, SOA, PEST, Claim, and White Space analysis.* Reporting - ** All necessary data are presented in format of wiki or in form of power point slides. ** Dashboard - Graphical representation of Patents classification.
==Rationale==
* LTE is the most suited mobile technology as it provides higher data rates required for the future and is an advancement improvement over widely used the established GSM/EDGE/HSPAsystems* A number of corporate giants are looking towards LTE is promoted by major corporates as the technology enabling future communication* The following factors advantages are expected to be obtained with the realization of LTE
** Reduced cost per bit
** Increased service provisioning - more services at lower cost with better user experience
==Background description==
LTE (Long Term Evolution), is the latest standard in the mobile network technology that came into existence because of the growing needs of faster data rates. It is a 3rd Generation Partnership Project (3GPP), which realized this technology. LTE is an advancement to previously realized technologies such as GSM/EDGE and UMTS/HSxPA etc.Although LTE is often marketed as 4G, first-release LTE is actually a 3.9G technology since it does not fully comply with the IMT Advanced 4G requirements.
Update - LTE-Advanced has been granted 4G compliance given the significant improvement they provide over 3G technologies [http://www.itu.int/net/pressoffice/press_releases/2010/48.aspx]
[[Image:lte-evolve.jpg|centre|500px|thumb|[http://www.4gamericas.org/index.cfm?fuseaction=page&sectionid=249 '''LTE Evolution''' ]]]
 Voice traffic will be supported mainly as Voice over IP (VoIP) enabling better integration with other multimedia services.LTE is being designed to be a high data rate and low latency system. LTE is also aimed at minimizing cost and power consumption while ensuring backward-compatibility and a cost effective migration from UMTS systems.
[http://www.radio-electronics.com/info/cellulartelecomms/lte-long-term-evolution/3g-lte-basics.php LTE tutorial]
There are two types of LTE frame structure:
* '''Type 1:used for the LTE FDD mode systems'''
** The basic type 1 LTE frame has an overall length of 10 ms. This is then divided into a total of 20 individual slots. LTE sub frames then consist of two slots - in other words there are ten LTE sub frames within a frame.
[[Image:type1f.jpg|thumb|centre|600px|[http://www.radio-electronics.com/info/cellulartelecomms/lte-long-term-evolution/lte-frame-subframe-structure.php LTE frame structure]]]
* '''Type 2:used for the LTE TDD systems'''
** The frame structure for the type 2 frames used on LTE TDD is somewhat different. The 10 ms frame comprises two half frames, each 5 ms long. The LTE half-frames are further split into five sub frames, each 1ms long.
