LTE UE category allows network to operate with terminals with different data capabilities as well as allows market to differentiate between low end devices with lower data capabilities against high-end devices with higher data rates. This differentiations determines price or UEs in many cases. In LTE not all UEs support all categories and also terminals from an earlier release does (more ..)
This tutorial describes LTE Handover types and procedures. LTE changed the way traditional mobile network were working. Leaving circuit switched technology far behind LTE became the first All-IP mobile network. Ĺike other mobile networks LTE also have big challenges when it comes to mobility areas like handover and reselection. Handover in particular is more complicated in LTE as LTE has (more ..)
Which LTE band is used in most deployments? What is the LTE band used by most operators? There are many LTE networks deployed till now but 1800 MHz is the most popular band among operators. In fact over 37% of LTE networks are based on 1800 Mhz band. 113 LTE networks are deployed till now in 51 countries and the (more ..)
Latest GSA report states that LTE TDD is not following the same global deployment trend as LTE FDD. According to the latest status 113 LTE operators have launched commercial services in 51 countries and most of the deployments used LTE FDD (Paired Spectrum). Out of 113 only 11 LTE deployments are done in unpaired spectrum (LTE TDD). Significant spectrum resources (more ..)
LTE was developed for packet based services. But a majority part of today’s traffic comes from CS based services like Voice and SMS. So 3GPP agreed to provide an intermediate solution for CS (Circuit Swtich) based services till IP based services like VoLTE completely developed and deployed. Using CSFB (CS Fallback) UE can move to GERAN, UTRAN or CDMA2000 systems (more ..)
Voice Over LTE is the next generation voice and video communication over LTE network. The mobile communication standard Long-Term Evolution (LTE) is optimized for data transfer and designed as a packet switched all-IP system only; it does not include any circuit switched domain currently used for regular voice and SMS services. Demand for mobile broadband services is proven in the (more ..)
There are many way to waste UE battery power but there are some ways to save this rare and useful resource. Fast Dormancy is one of these. Fast dormancy was introduced in 3GPP release 8 of the specifications after that it was a huge hit among all the smart phone manufacturers. The basic principle behind Fast Dormancy is quite simple (more ..)
