Course 570: Long Term Evolution (LTE) Fundamentals

LTE (Long Term Evolution) delivers true mobile broadband for the masses with a superior user experience. TONEX training services covers the adoption of mobile multimedia and the delivery of a true mobile broadband experience through our leadership in 4G-enabled technologies (WiMAX, LTE (Long Term Evolution), UMB (Ultra Mobile Broadband), and IMS (IP Multimedia Subsystem).  LTE is the natural evolution of 3GPP GSM and WCDMA networks.

LTE provides improved performance, lower total cost of ownership and enables a new era of personalized services. TONEX “LTE” (3GPP Long Term Evolution) covers the technical details of the next-generation network beyond 3G.
