Benefit of 1.4GHz for Mobile Downlink
There could be up to eight times as much data being downloaded than is being uploaded in mobile networks. This imbalance is expected to grow, as rich mobile content is increasingly made available and as consumer demand continues to soar. The study found that the use of the 1.4 GHz band as a supplemental downlink band for mobile applications is shown to drastically ease capacity, to enable considerably higher user data rates, to substantially enhance the user experience and to provide significant economic benefits.

100+ LTE Commitments, 22 commercial networks planned for 2010
The Global mobile Suppliers Association (GSA) has published an update to its Evolution to LTE report which confirms that 101 firm LTE network deployments are in progress or planned in 41 countries. The number of network commitments is 71% higher than GSA reported in a similar survey six months ago.
This figure includes three LTE systems which have launched commercial service – in Sweden, Norway, and Uzbekistan. GSA anticipates up to 22 LTE networks will be in commercial service by end 2010.
Another 31 operators are engaged in various LTE pilot trials and technology tests (these are referred to as pre-commitment trials). Taken together, it means that 132 operators are now investing in LTE in 56 countries.
The GSA Evolution to LTE report covers both LTE FDD and LTE TDD modes, and provides a summary of the market situation in each country, including operator activities and plans, spectrum requirements and developments, information on the growing eco-system including device and platforms availability, performance and interoperability trials results, key industry trends and forecasts.
LTE networks are now being deployed for commercial service or planned in Armenia, Australia, Austria, Bahrain, Brazil, Canada, Chile, China, Denmark, Estonia, Finland, France, Germany, Hong Kong, Hungary, India, Ireland, Italy, Japan, Jordan, Kazakhstan, Kuwait, Latvia, Libya, Netherlands, New Zealand, Norway, Portugal, Russia, Saudi Arabia, Singapore, South Africa, South Korea, Sweden, Switzerland, Taiwan, The Philippines, UAE, UK, USA, and Uzbekistan.
Governments around the world are preparing the way to ensure the availability of spectrum to support delivery of next generation mobile broadband services for the mass market, by allocating or preparing for the release of new spectrum such as 2.6 GHz, and in the digital dividend (700 MHz, 800 MHz) bands, or re-farming existing spectrum e.g. 900 MHz, 1800 MHz, etc. or facilitating a combination of new and re-farmed bands. The report notes that several trials licenses have been granted in many countries to allow operators to familiarize with the technology, capabilities and performance aspects. A number of tenders for spectrum licenses have been announced or confirmed in recent weeks for the granting of spectrum suitable for LTE deployments, including in Australia, Brazil, Chile, Poland, and the UK. Several auctions are scheduled for completion in the next few months.
LTE is the next generation mobile broadband technology of choice and the natural evolutionary step for GSM/WCDMA-HSPA operators and also for many leading CDMA operators around the world. A leading WiMAX operator has also recently announced the company has decided to shift to LTE.
While the majority of LTE deployments today are using the FDD mode, the report confirms significant operator interest in the TDD mode. LTE FDD and LTE TDD are complementary technologies and standardized by 3GPP. A number of key technology milestones have been demonstrated in recent weeks which confirm how the LTE TDD system is maturing towards commercialization. The recently concluded BWA spectrum auction in India has paved the way for early and large scale introduction of TDD LTE into the world’s fastest developing market.
Alan Hadden, President, GSA said: “Our latest Evolution to LTE report shows how the pace towards LTE has quickened, which is easy to see from the increasing numbers of operator trials and announcements, and positive actions by several regulatory bodies around the world”.
