Evolution from GSM to LTE-Advanced and Voice over LTE (VoLTE)

From GSM to Voice over LTE (VoLTE)

Voice-over-LTE is a big deal for mobile operators worldwide today moving subscribers from their traditional 2G networks to their new 4G networks. Operators want to to get off of GSM and CDMA and on to LTE to increase their capacity tenfold or more for their networks.

Voice and messaging services for Long-Term Evolution (LTE) is happening.  Using IP Multimedia Subsystem (IMS) developed by 3GPP, end-to-end voice and SMS messaging along with Roaming and Interconnection is a reality now.

VoLTE is built upon underlying 3GPP principles including LTE and IMS. VoLTE has similar characteristics like Vonage. It is more than just Voice over IP (VoIP). The IP networks are mostly managed with MPLS or other layer 2/3 techniques.

Rather than connecting an legacy circuit switched call, VoLTE calls are transmitted over LTE EPC and IMS networks using SIP as the signaling protocol.

VoLTE can use "HD Voice" or Rich Communication Services (RCS) will merge picture and video messaging.

RCS (Rich Communication Services) will deliver high quality voice and SMS by providing them with instant messaging or chat, live video and file sharing across any mobile device, on any network.  

LTE Training - Long Term Evolution (LTE) Training

Long Term Evolution (LTE) Learning

One interesting facet of the convergence of mobile broadband and IP world is this new emerging LTE , Long Term Evolution, technology that will take the place of traditional mobile networks globally in the near future. TONEX actually started its LTE Training in 2004 , which really has surprised many people. It’s better to learn LTE, VoLTE, LTE RF Engineering and LTE-Advanced now and become an expert in this field so you can have a leg up on the rest of the engineers when it’s time to get a job.

We also offer a LTE RF Planning and Engineering course where it teaches you LTE propagation modeling, planing and RF Optimization. It might seem complicated to you but these courses look pretty good.  The bottom line is that knowing LTE as a project manager, or being a LTE systems engineer can make for a very lucrative career choice.
