Comprehensive VoLTE – Voice Over LTE description with details on end-to-end architecture, call handling, roaming and handover to UMTS and GSM. LTE as its core is an all IP network in which data connectivity is given more importance than traditional voice and SMS services. But similar to its predecessors LTE eventually require a way to support CS and messaging services (more ..)
Intel latest LTE slim modem offering has some key improvements over its predecessors. Intel® XMM™ 7160 will be multi-mode means it will support more than one bands to offer LTE roaming. Here are the some of the key specifications of Intel’s latest mobile modem offering: 4-band EDGE 5-band HSPA+ Multi-band LTE 42 Mbps DC-HSPA 100 Mbps LTE EDGE MSC33 CPC (more ..)
The total number of mobile subscriptions in the world is expected to reach five billion soon and the number is ever increasing. This has given a good opportunity to venture capitalists and business people to invest in the mobile business sector. With the number of network operators increasing in most of the countries, investors want to gain as much market (more ..)
Self Organizing Network helps in reducing the system overload in an automated way. This new video from Ericsson describes what is SON and how Self Organizing Network will help not only LTE but also in older technologies like 3G and 2G. Automation creates value within the network and self organizing networks are increasingly important not only to lower costs of (more ..)
Mobile phones had a long history. The last three decades of mobile phones is quite amazing. Check out this infographic.
Voice over LTE – VoLTE is the technology to provide voice and video services over LTE all PS network. As LTE is a complete PS network VoLTE need to use IMS in EPS core to handle voice and video related services. Apart from IMS, VoLTE enabled UE (User Equipment) use MME (Mobility Management Entity) to authenticate a UE prior to (more ..)
Heterogeneous networks (HetNets), consisting of Macro NodeBs (macros) and low power Pico NodeBs (picos), can increase system capacity by offloading some users to the picos. However, this offloading may be limited due to intercell interference from macros to picos that reduces their coverage. HSPA Multi-carrier HetNets allow the use of range expansion techniques to achieve more offloading, such as power (more ..)
