Nokia is without a doubt a big company and one of the largest mobile phone manufacturers in the world and now it has signed up sony ericsson, NEC and Alacatel-Lucent to its plans for a 4G wireless system. These companies have all formed a licensing framework for their emerging mobile standard which is called LTE (Long Term Evolution)
Simply put, LTE describes the evolution of mobile technology that will deliver users the benefits of faster data speeds and new services by creating a new radio access technology that’s optimized for IP-based traffic and offers operators a simple upgrade path from 3G networks. Alongside LTE is work on the evolutionary development of the core architecture of mobile networks, called system architecture evolution (SAE). Together, they will offer operators networks with significant performance enhancements over 3G, with a target of two to four times the spectral efficiency of 3G/HSPA networks. This means LTE networks will be able to squeeze more bits of data into the same amount of spectrum as 3G and HSPA networks, translating into increased data speeds and/or increased capacity. Nokia and its partners believe LTE is the logical evolution of 3G systems and are selling it as a solution for mobile phones, as well as laptops and even fixed broadband connections, replacing wi-fi.
