Network Sharing: Support of Multi-Operator Core Network by GERAN (MOCN-GERAN)

By agaur on December 22, 2012
Network Sharing - MOCN GERAN
With a number of spectrum reframing (e.g. 900 MHz spectrum re-farming) being done to free up band for LTE technology use, operators may have to reduce their GSM capacity and may share their GSM networks. As re-farming significantly reduces the set of frequencies allocated to GSM, 3GPP decided to look in to the RAN sharing method and along with supporting companies found that MOCN (Multiple-Operator Core Network) is optimal RAN Sharing method.

Local Call Local Switch System (LCLS) Overview

By agaur on December 7, 2012
Local Call Local Switch System Architecture
The transmission path is an important part of wireless networks. In wide rural areas or in remote areas, operators sometimes face the challenges to deploy networks due to the lack of or cost of fast and reliable backhaul transport network. Statistical data indicate that many calls in a mobile network in these areas are local calls. There is good probability that call between two terminals go via same BTS or in between co-located BTSs or with in same BSC.

Introduction to Cognitive Radio (CR)

Cognitive Radio
Communication devices today are becoming ever more sophisticated and diverse, delivering a plethora of new services and applications. The last hop to the end user, a person or device, is increasingly being delivered wirelessly. This sophistication brings with it complexity, making conventional approaches to organisation, implementation and regulation increasingly inadequate.

Seamless WLAN Offload with IP Mobility

By agaur on November 6, 2012
Evolved Packet System
Wireless service provides across the globe are aiming to lower the cost for providing data service while meeting the increased demand due to exponential growth in mobile data traffic thanks to popular smartphones.  Since few years, Wi-Fi  offload had been a preferred choice for operators to balance the IP traffic. However, WiFi offload is not often seamless to end user.

Cellular Heterogeneous Networks: Networks of Multiple Radio Access Technologies

Heterogeneous Networks
Cellular standards have evolved rapidly in last couple of decades and as of today multiple mobile access technologies exist in operator’s network.  Increased demand for low cost mobile broadband connectivity is driving the development of heterogeneous cellular networks.

Wireless Body Area Network (WBAN) - A Health Monitoring Technology

By kamal on October 16, 2012
Wireless Body Area Network
Wireless sensor technologies have seen as rapid growth in recent years. This rapid technological advances resulted in low cost, light weight, small size and intelligent wireless sensor nodes. These nodes can be strategically placed on the human boday and connected by means of wireless network. This arrangement of wirelessly connected sensor nodes on the human body is known as Wireless Body Area Network (IEEE 802.15.6).

LTE Voice Options: CSFB & VoLTE


CSFB and SMSoSGs

in TutorialCSFBIMSSMSoSGsLTE
The CS FallBack (CSFB)  in EPS enables the provisioning of voice and other CS-domain services (e.g. CS UDI video, LCS, USSD) by reuse of CS infrastructure when the UE is served by E-UTRAN. A CSFB enabled terminal, connected to E-UTRAN may use GERAN or UTRAN to connect to the CS-domain.

Validating voice over LTE end-to-end

in TutorialEricssonVoLTELTE
Ericsson - Unlike previous 3GPP wireless technologies, LTE has no circuit-switched bearer to support voice, so carrying voice over LTE requires a migration to a voice over IP (VoIP) solution – commonly under the umbrella of IMS. Until this migration occurs, LTE-capable handsets need to revert to 2G or 3G for voice calls: an approach that is not ideal in the long term.

4G LTE WiMAX Courses

4G technologies LTE & WiMAX are being deployed worldwide with LTE taking lead now. Many commercial LTE/WiMAX networks are already in-service worldwide and many planned to go live. 3GPP LTE (Long Term Evolution) Project was launched to improve the UMTS mobile phone standard to cope with future technology evolutions. Goals include improving spectral efficiency, lowering costs, improving services, making use of new spectrum and reframed spectrum opportunities, and better integration with other open standards. Based on IEEE 802.16 standard, WiMAX, the Worldwide Interoperability for Microwave Access provides wireless data over long distances in a variety of ways, from point-to-point links to full mobile cellular type access.

Individuals interested in understanding how 4G technologies being leveraged to enhance end-user experience in a wireless network and how 4G network would be deployed should attend these courses. Those who already have a working knowledge of 3G; or telecom professionals who currently serve in sales, systems engineering, architecture, design, test, support, or operations roles will find these courses to be especially beneficial.
