TELECOM TESTING

What is LTE

LTE (Long Term Evolution) is the project name given to development of a high performance air interface for cellular mobile communication systems. It is the last step toward the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile telephone networks. While the former generation of mobile telecommunication networks are collectively known as 2G or 3G, LTE is marketed as 4G.

According to 3GPP, a set of advanced requirements was identified:

  • Reduced cost per bit
  • Increased service provisioning – more services at lower cost with better user experience
  • Flexibility of use of existing and new frequency bands
  • Simplified architecture, Open interfaces
  • Allow for reasonable terminal power consumption

Although there are major changes between LTE and its 3G predecessors, it is nevertheless looked upon as an evolution of the UMTS / 3GPP 3G standards. LTE uses a different form of radio interface (OFDMA / SC-FDMA instead of CDMA), but there are many similarities with the earlier forms of 3G architecture and opportunities for re-use of some elements of 3G network architecture. LTE can be seen as providing an evolution of functionality, increased speeds and general improved performance compared to 3G.


Artiza Networks is the leader in 3G, 4G, and pre-5G radio access network (RAN) and core network (CN) node testing. For over 20 years, Artiza has collaborated with the industry’s top vendors and operators in testing the RAN and core network nodes of the world’s most advanced cellular networks. We cooperated with a major vendor and operator in Japan to perform the first ever experimental trial of LTE technologies. Since then, our high-density load testers have dominated the Japanese market, and set the standards for our global partners.
