GSM 900 Refarming (UMTS 900):- Key topic after 3G spectrum Auction

Spectrum refarming is one of the most significant regulatory but those with 900MHz assets see refarming as a threat to their competitive advantage as well as to the quality of their networks. Although operators may feel threatened by the prospect of losing their existing spectrum assets, the opportunity to expand coverage and reduce costs outweighs any hesitation they may have about service deterioration or loss of market share from reduced spectrum holdings.

Generally speaking, refarming may be seen as process constituting any basic change in conditions of frequency usage in a given part of radio spectrum. Such basic changes might be:

• Change of technical conditions for frequency assignments
• Change of application (particular radio communication system using the band)
• Change of allocation to a different radio communication service.

Before we move further, it would be useful to understand the generic spectrum usage plan. The diagram below shows the how the different frequency bands are being used for different purposes.

Key Benefits of UMTS 900

1. Coverage – Ovum’s analysis indicates that UMTS900 provides between 44% (in urban areas) and 119% (rural areas) increased coverage per Node-B compared with UMTS2100. This is primarily due to the propagation characteristics of the lower frequency band. All 3G applications can be provided and used cost efficiently over much larger area as the coverage radius in 900 MHz is almost double than that of 2100 MHz spectrum
2. Cost Effective –Radio wave propagation loss is less in 900 MHz, so fewer base stations are required leading to cost savings of around 50–70% compared with networks deployed in 2100MHz core-band 3G spectrum. These coverage and cost-saving benefits mean that operators can bring 3G services to less-densely populated areas that were previously uneconomical to cover
3. Better Quality of Service (QoS) - Since fewer base stations are required for UMTS 900 roll-out than UMTS 2100, the customer experience is better due to fewer hand-overs. Lower frequency band have a higher in-building penetration. Over 70% of phone calls are now made indoors and UMTS 900 can help improve the Quality of Service (QoS)

Regulatory status of spectrum refarming worldwide

As mentioned earlier, the European Union has already ratified the GSM directive on spectrum refarming and it is obligatory on part of its 27 member countries to change their laws in line with this directive. However, in most of the countries, it is up to the individual Governments to allow UMTS 900. It is necessary in some countries to re-arrange the band allocations by agreement with network operators in order to enable GSM & UMTS900 in 900 MHz spectrum.

Operators who have launched commercial 900 MHz 3G services

13 operators have UMTS 900 networks across the world till date but the reasons for the roll-out on 900 MHz vary from operator to operator.

Optus Australia launched UMTS 900 to increase its coverage. With a combination of 900 and 2100 MHz, it managed to increase its coverage to 96% of population. AIS in Thailand launched UMTS 900 as the 3G spectrum (2100 MHz) auction was getting delayed. Elisa launched UMTS 900 to save costs.

UMTS 900 Device Market

As per GSA HSPA devices survey conducted in October, 2009, 190 UMTS-900 HSPA devices have been launched in market by 34 suppliers (this includes 39 USB dongles). Most of the HSPA handsets now have 900 MHz support as well.

Will the operators completely switch off 2G in favour of UMTS900

The operator business is getting complex with many operators having to manage 2G, 3G and LTE networks. It is expected that with the stabilization of LTE by 2016/17, the operators would switch off their 2G networks (so far Japan is the only country to switch off 2G networks). However, due to the migration to UMTS 900, it is possible that the operators switch off the 2G networks much before the expected timelines. This would help the operators save on opex for running multiple networks and would also make the operations less complex requiring fewer people. The 2G network can be sold off to new operators coming up in emerging countries. However, there are a few challenges that would hold the operators back from switching off 2G networks:

• Migration from 2G to 3G handsets: Though the spectrum band would remain the same at 900 MHz, the 2G users would need to replace their handsets to be able to use the 3G network. The carrier would need to provide handset subsidy to encourage the users to replace their handsets but then the benefits have to be substantially higher than the costs involved
• Inroaming Revenues: With the voice tariffs dipping, the roaming revenues are a significant portion of the revenues. In case an operator decides to switch off the 2G networks, the users from other 2G networks will not be able to log on to the operator’s network. This loss of revenues may not be sufficiently covered by any opex savings or ARPU upside
• 1800 MHz: Many 2G networks are on 1800 MHz. UMTS 1800 is still not a viable option given the low ecosystem support. Apart from this, many operators may be holding both 900 and 1800 MHz spectrum and optimizing between the two. In this situation, the operator may not want to switch off 2G network

Evolution to HSPA+

Evolution path for UMTS/WCDMA Network.

High Speed Packet Access Plus

HSPA+: High Speed Packet Access Plus

HSPA+ (High Speed Packet Access Plus) is also known as HSPA Evolution and Evolved HSPA. HSPA+ was standardized in 3GPP Release 7 and Release 8. HSPA+ will apply some of the techniques developed for Long Term Evolution (LTE) and allow operators to extend the life of their HSPA networks. 3G Americas initiated proposals at 3GPP to lead the development of the HSPA+ standards which now have received wide scale commitments from operators.

HSPA+ will bring improved support and performance for real-time conversational and interactive services such as Push-to-Talk over Cellular (PoC), picture and video sharing, and Video and Voice over Internet Protocol (VoIP) through the introduction of features like Multiple-Input Multiple-Output (MIMO) antennas, Continuous Packet Connectivity (CPC) and Higher Order Modulations.

Some of the key features of HSPA+ include the following:

• HSPA+ is a simple upgrade to today’s HSPA networks, protecting an operator’s investment in the network. HSPA+ enhancements are backward-compatible with UMTS Release 99/Release 5/Release 6
• HSPA+ provides a strategic performance roadmap advantage for incumbent GSM-HSPA operators providing OFDMA-equivalent performance in 5X5 MHz spectrum allocations with only incremental investment. HSPA+ could match, and possibly exceed, the potential performance capabilities of IEEE 802.16e-2005 (mobile WiMAX) in the same amount of spectrum, and could match LTE performance when using 5 MHz of spectrum.
• HSPA+ will significantly increase HSPA capacity as well as reduce latency below 50 milliseconds (ms)
• The first phase of HSPA+ with 64 QAM has already been deployed commercially and is providing peak theoretical downlink throughput rates of 21 Mbps
• HSPA+ with 64 QAM and advanced antenna techniques such as 2X2 MIMO can deliver 42 Mbps theoretical capability and 11.5 Mbps on the uplink and could be ready for deployment in 2010
• Smooth interworking will be provided between HSPA+ and LTE that facilitates operation of both technologies. As such, operators may choose to leverage the System Architecture Evolution/Evolved Packet Core (SAE/EPC) planned for LTE.
• HSPA+ supports voice and data services on the same carrier and across all of the available radio spectrum and offers these services simultaneously to users

HSPA+ is an affordable and incremental upgrade to existing HSPA networks. It provides a tremendous advantage to HSPA operators, which is not an option for CDMA operators who are already unable to compete with the higher data throughput performance of HSPA and have no future evolution commercially viable for enhancement to their EV-DO networks today. Because it offers impressive performance at an incremental cost, some HSPA operators plan to use HSPA+ as a companion to LTE.

Telstra in Australia, Starhub in Singapore, CSL in Hong Kong and Mobilkom Austria in Central and Eastern Europe were the first operators to launch commercial HSPA+ networks in early 2009, initially providing peak theoretical download speeds of 21 Mbps. Several operators such as Telstra plan to upgrade their networks to 42 Mbps in the short term.

High Speed Packet Access

HSPA: High Speed Packet Access

HSPA - High Speed Packet Access is the most widely deployed mobile broadband technology in the world today and will build upon the 3.8 billion connections with the GSM family of technologies. HSPA is the terminology used when both HSDPA (3GPP Release 5) and HSUPA (3GPP Release 6) technologies are deployed on a network. HSPA Evolved (HSPA+ in 3GPP Release 7 and beyond) is also part of the HSPA technology and extends an operator’s investment in the network before the next step to 3GPP Long Term Evolution (LTE, or 3GPP Release 8 and beyond). HSPA builds on third generation (3G) UMTS/WCDMA and is strongly positioned as the leading mobile data technology for the foreseeable future.

According to independent analyst firm Informa Telecoms & Media, more than 94 percent of UMTS/WCDMA operators launched HSPA by the end of 2008. At the time, Informa reported there were 82.8 million HSPA customers worldwide and that number is expected to top 800 million by 2013.

Globally, there are more than 265 commercial networks with HSDPA of which 77 have been upgraded to HSPA; in Latin America, there are 47 HSDPA networks in 23 countries (May 2009). All UMTS and HSDPA networks are expected to be upgraded to HSPA.

Many HSPA networks, approximately 70% as of 1Q 2009, offer 3.6 Mbps peak downlink rates with the bulk of the remainder offering 7.2 Mbps. However, continued progress by vendors and leading innovative operators, allows for HSPA networks capable of peak bit-rates of 14.4 Mbps. The first networks using 64 QAM modulation and offering 21 Mbps are also in operation. The use of higher order modulation schemes (from 16 QAM up to 64 QAM), along with MIMO technology, takes HSPA into ‘HSPA+’ or evolved HSPA such as developed in 3GPP Release 7.

Propelling the strong growth is a strong selection of devices supporting HSPA. The GSMA reported that more than 1,343 HSPA devices were on the market from 135 suppliers as of 1Q 2009.

Whereas HSDPA optimizes downlink performance, HSUPA uses the Enhanced Dedicated Channel (E-DCH) for a set of improvements that optimizes uplink performance. Networks and devices supporting HSUPA became available in 2007 and the combined improvements in the uplink and downlink are called HSPA. These improvements include higher throughputs, reduced latency and increased spectral efficiency. HSUPA (HSPA) is standardized in Release 6 and results in an approximated 85 percent increase in overall cell throughput on the uplink and more than 50 percent gain in user throughput. HSUPA also reduces packet delays, a significant benefit resulting in significantly improved application performance on HSPA networks.

Typical HSPA downlink user achievable rates are 1 to 4 Mbps and typical user achievable HSPA uplink speeds are 500 kbps to 2 Mbps as of 1Q 2009. Theoretical peak speeds are significantly higher at 14 Mbps on the downlink and 5.8 Mbps on the uplink in a 5 MHz channel.

Beyond throughput enhancements, HSPA also significantly reduces latency. In optimized networks, latency will fall below 50 milliseconds (ms), relative to current HSDPA networks at 70 ms. And with a later HSPA introduction of 2 ms Transmission Time Interval (TTI), latency will be as low as 30 ms.

HSPA gives carriers an efficient mobile broadband technology that can evolve to HSPA+ to meet the advanced wireless needs of customers. To leverage operator investments in HSPA and enhance the quality of service across networks, standards body 3GPP finalized Release 7 and Release 8, which specify a series of enhancements to create HSPA+. Also, 3GPP is examining further specifications in Release 9. HSPA+ employs many of the techniques utilized for LTE.
