LTE a major element for the next Billion

The latest 4G Americas data puts the total number of 3GPP mobile subscriptions at 5.2 Billion, accounting for 90% of all mobile phone users.

LTE represents only 3.8 million of those subscriptions, or less than 1%, but these are still early days for the technology and great things are expected - as highlighted in the“Evolution to LTE” report from the Global mobile Suppliers Association, where LTE is described as “the fastest developing mobile system technology ever”, based on solid statistics on product announcements and on 248 operator commitments.

GCF certification for dual-mode LTE and UMTS devices

The Global Certification Forum is now able to provide assurance that dual-mode LTE / UMTS devices can hand-off sessions between the two radio-access technology families.

A recent GCF press release gave details of the first dual-mode device to achieve certification, supporting 2100 MHz LTE and other 3G radio - HSPA and WCDMA - in the 800 & 2100 MHz bands.

The Forum now expect a growing number of devices for further band combinations, adding to a heavy work load that has seen the approval of more than 470 different 3GPP mobile phones, wireless modems and connected devices in the past 12 months.

3GPP Specs in LTE Voice Call Tests

The MultiService Forum, working closely with the GSMA has demonstrated successful VoLTE calls and MMTel services across different networks, using equipment from 19 participating equipment manufacturers.

To promote the success of the event, they have also published a white paper - “MSF VoLTE Interoperability” - which concludes that “…VoLTE is a viable solution for providing voice services over LTE access technology, and can be deployed with roaming and interconnect functionality to provide equivalent service as CS-based voice services today.”

The 3GPP interfaces (Technical Specifications) used during testing were fully listed in Section 3 of the MSF Testing Scenarios created for the event.

Sitting pretty with HSPA and LTE

High-Speed Packet Access (HSPA) systems are now common place across Latin America and a recent white paper points to growing evidence that operators are looking to get full benefit from this technology as it evolves to HSPA+.

Although the future is LTE, the region is a good example of how 3G networks can take the customer all the way to the cusp of that new era. Progress made since 3GPP Release 7 has allowed HSPA+ to benefit from the techniques used in the elaboration of LTE to ensure that both support smart phones, tablets and PCs as user needs grow.

RBS energy savings

The Environmental Engineering (EE) committee of ETSI has published its latest Technical Specification , to help operators improve the energy efficiency of their networks.

According to this weeks' ETSI Press release: "...TS 102 706, developed by ETSI 'EE' Technical Committee, standardizes the measurement method for energy efficiency for multiple mobile network technologies, such as GSM/EDGE, W-CDMA/HSPA, LTE and WiMAX networks."
