NSN Sees 5X GSM Performance Boost for SmartPhone Packets

Nokia Siemens Networks announced a new Smart Resource Adaptation software feature that enables GSM networks up to five times more smart device users with higher data throughput and less congestion. The software technique allocates packet resources based on actual use of smart device applications.


Nokia Siemens Networks said the performance boost is made possible due to the current mismatch between packet sizes traversing GSM networks. According to the company, GSM networks have been optimized for data applications that create large packet sizes and require high throughput.


However, about half of the total data volume handled by these networks today is generated by smart applications that actually produce small packets.


"If these applications are not effectively accommodated, they will end up blocking available data traffic channels, resulting in severe network congestion and slower data speeds for users," said Prashant Agnihotri, head of GSM/EDGE product management, Nokia Siemens Networks.


The new Smart Resource Adaptation software feature allocates radio timeslots on the network for applications according to actual use. This frees data traffic channels for applications that require high throughput.


NSN calculates that by managing packet radio resources more efficiently, the software can deliver up to five times higher GSM radio network efficiency for applications that generate small packets.


The Smart Resource Adaptation feature will be available in the second quarter of 2011.

  • In August 2010, Nokia Siemens Networks announced a unique Dynamic Frequency and Channel Allocation (DFCA) feature that that it claims will double GSM network capacity within existing spectrum. DFCA leverages a combination of software capabilities to increase the traffic carrying capacity of existing sites, while improving network quality. This, in turn, minimizes the immediate investment in additional sites, reducing the total cost of ownership. An added benefit is a huge increase in energy efficiency per subscriber.


  • In January 2009, Nokia Siemens Networks announced the successful implementation of Orthogonal Sub Channel (OSC) technology to carry four calls in one GSM radio timeslot. This effectively doubles the voice capacity of the GSM radio network. The OSC demonstration was conducted as a drive test using four handsets sharing only one radio timeslot and without compromising the call quality. The demonstration, which was held on January 21, used existing commercially available GSM handsets. Nokia Siemens Networks said the OSC demonstration was the first of its kind The company is actively contributing to the standardization of OSC and is planning to have the technology commercially available in 2010.
