The remaining sections o Into greater technical detail about LET and WOMAN wireless technologies. 1. 1 Statement of the Problem we analyze the deployed Releases of Long Term Evolution (LET) technology, their advantages and drawbacks.
Based on the existing Releases, from 5 to 10 [1, 2], we put a question on how to integrate the advanced LET technology and multiple-input- multiple-output (IMO) system for multi-user (MO) multiple access deployment, which we call the Advanced LET Release II/IMO network.We analyze this account multi-parametric stochastic approach that combines the statistical ascription of the terrain and the built-up overlay with description of the signal intensity spatial distribution, taking into account the channel multipart effects from various natural and artificial obstructions located in the urban scene. The Rican K- parameter is used for multiplicative noise description, as a ratio of the coherent and incoherent components of the signal intensity [3].Using the K-factor spatial distribution depending of the features of built-up terrain, an information data stream both for IMO correlated antennas (the good case) and uncorrelated IMO antennas (the worst case), as well as the capacity and spectral efficiency are predicted, depending on the "reaction" of different kinds of the terrestrial channel - rural, mixed residential, rural and urban.
Finally, we give practical recommendations of how using the proposed combined LET/IMO Network with a Multi-beam antenna system will increase the system's capacity.This will allow the designers of wireless networks to obtain maximum data rate, better channel spectral efficiency and less bit error rate, and as a result, much better service and transmission performances. 1. 2 Theoretical and Conceptual Framework Driving the evolution of wireless broadband technology is customers' increasing expectations for speed, bandwidth, and global access. Customers want more information, such as business and consumer applications, and entertainment available through their mobile devices, but with greater speeds.For wireless carriers to achieve greater speeds and pervasive connectedness, their networks need to start behaving more like landlines IP-based networks.
This line of thinking represents a fundamental shift in perspective?from mobile services to broadband connections?for customers and service providers alike. Enter the fourth generation (46) wireless network. Unlike earlier wireless standards, G technology is based on TCP/IP, the core protocol of the Internet. TCP/IP enables wireless networks to deliver higher-level services, such as video and multimedia, while supporting the devices and applications of the future.Verizon Wireless chose LET over Woman as the technological foundation for its G wireless broadband network.
The company believes that LET offers a number of significant technological and business advantages over Woman that make it a superior networking standard. Verizon Wireless customers want to be truly undeterred with advanced communication devices that provide a similar immersed experience as found in today's wired networks?whether it's downloading or uploading large files, video, gaming, downloading music, or social networking.They want to be able to communicate in new and innovative ways whenever and wherever they choose around the globe. For these reasons, Verizon Wireless believes LET is the best technology with the global scale needed to deliver such experiences. 1. 3 Assumption and Hypothesis In 2010 they build 20 commercial LET networks across 14 countries would need cause in many cases migration to G LET is happening considerably faster than the earlier migration from 26 to 36.
LET users consume almost 1. KGB of data for month on average almost twice the average amount consume d by non-LET users. 1. 4 Significances of the Study customers?for both today and tomorrow.
For Verizon Wireless, selecting the right technology is imperative. As a leader in the wireless industry, Verizon Wireless is committed to the potential technology advances offered by LET. Wireless is currently conducting laboratory and field tests using LET technology and Lana to launch its G mobile network in 2010.This deployment will help the company realize its goal of delivering improved wireless Internet connectivity and mobility to its customers.
For the mobile user, connectivity means an undeterred experience and true mobility. Users can work and communicate almost whenever and wherever they want. Lute's improved speeds will allow wireless carriers to offer a number of business-specific applications and services, such as video conferencing, direct connectivity, and mobile applications that bring the desktop experience to mobile devices.
