VoLTE Radio Resource and Quality of Service Class Identifier Voice over Long Term Evolution, Voice over LTE or with abbreviated version VoLTE. Typically the mobile operators are using CSFallback feature for voice calls in new deployed LTE networks which is READ MORE
Here we will imagine the UE only in 3G network. When a 3G UE is powered on, firstly it starts to scan UMTS spectrum and tries to find strongest cell based on radio condition. This step is called as READ MORE
On above image, we can see overview of LTE Protocol Stack. Each part of the stack has its own responsibility. Details for these parts will be described in related pages, now let’s to understand the concept of the protocol stack READ MORE
Radio Frequency or with abbreviated version “RF” is any of the electromagnetic wave frequencies. Approximate range of radio frequency is between 3 KHz and 300 GHz which is used in radio communication. In this section we will talk about following READ MORE
Wireless communication systems should have a rapid solution to inform the people about natural disasters such as earthquake, tsunami or landslide. Currently one of the best notification solutions is ETWS for mobile users who are receiving pop-up messages on READ MORE
