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”.

With some much talk (and hype) surrounding NFC and Mobile payments, it looks quite possible that m-payments will enter mainstream in the Western world in the forthcoming year. Though mobile payments have become norm in developing countries like Kenya, Senegal and India, its yet to catch on in UK and the USA.

Since last few months, NSN have been showing that they are serious about TD-LTE as well. Back in June they made an announcement that they have integrated TD-LTE in their networks so that it can support concurrent use of TD-SCDMA and TD-LTE. They opened a TD-LTE lab in China as well earlier this year.Nokia Siemens Networks has proven its leading role in advancing TD-LTE as it met the complete TD-LTE test specifications defined by China’s Ministry of Industry and Information Technology (MIIT). The successful completion of the trial in the 2.3GHz band at the MIIT lab in Beijing, China, marks an important milestone in the commercialization of TD-LTE. After the test, Nokia Siemens Networks also achieved the world’s first high-definition TD-LTE video call, including handover, with a Samsung TD-LTE device.
The high-definition video call demo showcased interoperability between Nokia Siemens Networks’ LTE infrastructure and Samsung’s TD-LTE USB dongle, and marks a definitive step toward ensuring early availability of a functioning TD-LTE ecosystem for commercial deployments.
“We’ve achieved excellent results from this test and are happy to partner with Nokia Siemens Networks in driving the TD-LTE ecosystem further,” said Mr. Tong Wang, president of Beijing Samsung Telecom R&D Center. “Commercial readiness of devices is a key indicator for the success of a new technology and the current test results show that we are now well prepared for TD-LTE.”
“Meeting TD-LTE test specifications defined by MIIT and achieving the first high-definition video call with handover, are key milestones in our list of achievements, added Paul Pan, head of Network Systems, Greater China Region, Nokia Siemens Networks. “We will continue to collaborate with partners to accelerate our progress toward a comprehensive deployment of TD-LTE.”
Nokia Siemens Networks is at the forefront of TD-LTE development and commercialization, actively working with telecom operators and device manufacturers. The company recently announced the first TD-LTE interoperability data call with a prototype TD-LTE USB dongle from Samsung and the first TD-LTE video call between Shanghai and Taipei.
A recent demonstration from ip.access and AlertMe.com showed how femtocells can be integrated into smart-home energy-management solutions. With femtocell integration, the AlertMe Energy service can automatically detect when the house is empty and power down lights, televisions, and other home appliances. The service also can switch the services back on when the resident returns home.
For the demo, ip.access combined the AlertMe Energy service with its own femtocell technology. The solution works by allowing electrical appliances to switch on and off automatically in response to the presence or absence of mobile phones in the home. This “presence” information, which is routinely gathered by the femtocell, is normally only used to route cell-phone traffic and set tariffs.
In the demonstration, however, the AlertMe integration enables the presence information to be used to set light and power preferences, which are activated automatically when a subscriber arrives at home. Preset electrical outlets also can switch off automatically to save energy a few minutes after the last person has left the house.
The demonstration shows how supplementary service codes on the phone can be personalized through the femtocell when the phone is at home. For example, the phone can be used to remotely switch appliances on and off.
“One automatic trigger could be to switch the kettle on as soon as you arrive home,” says Dr. Andy Tiller, Vice President Marketing at ip.access. “But there is more to this than just tea and convenience. Using a femtocell to personalize supplementary service codes is a new and unique idea. It enables the mobile phone to become a powerful controller for all kinds of applications in the home. And because it’s a network-enabled feature, it works with any handset. There are no applications to install.”
According to AlertMe.com Founder Pilgrim Beart, “The mobile phone is increasingly the remote-control for your life. Most people carry their handset everywhere they go, making it an ideal control device for the AlertMe Energy service.”
The demo also shows how the AlertMe Hub (the central device that receives instructions via the Internet and controls the electrical plugs in the home) can be integrated inside a femtocell access point. It will then rely on the femtocell for power and its Internet connection. In this way, a mobile operator could offer a smart-home energy-management solution as an integrated option to its femtocell subscribers.
This kind of technology is probably quite a few years away.
Via PC World:How does the GSM snooping work?
Chris Paget was able to patch together an IMSI (International Mobile Identity Subscriber) catcher device for about $1500. The IMSI catcher can be configured to impersonate a tower from a specific carrier. To GSM-based cell phones in the immediate area--the spoofed cell tower appears to be the strongest signal, so the devices connect to it, enabling the fake tower to intercept outbound calls from the cell phone.
What happens to the calls?
Calls are intercepted, but can be routed to the intended recipient so the attacker can listen in on, and/or record the conversation. To the real carrier, the cell phone appears to no longer be connected to the network, so inbound calls go directly to voicemail. Paget did clarify, though, that it's possible for an attacker to impersonate the intercepted device to the wireless network, enabling inbound calls to be intercepted as well.
But, aren't my calls encrypted?
Generally speaking, yes. However, the hacked IMSI catcher can simply turn the encryption off. According to Paget, the GSM standard specifies that users should be warned when encryption is disabled, but that is not the case for most cell phones. Paget explained "Even though the GSM spec requires it, this is a deliberate choice on the cell phone makers."
What wireless provider networks are affected?
Good news for Sprint and Verizon customers--those networks use CDMA technology rather than GSM, so cell phones on the Sprint or Verizon networks would not connect to a spoofed GSM tower. However, AT&T and T-Mobile--as well as most major carriers outside of the United States--rely on GSM.
Does 3G protect me from this hack?
This IMSI catcher hack will not work on 3G, but Paget explained that the 3G network could be knocked offline with a noise generator and an amplifier--equipment that Paget acquired for less than $1000. With the 3G network out of the way, most cell phones will revert to 2G to find a viable signal to connect to.
A researcher released software at the Black Hat conference on Thursday designed to let people test whether their calls on mobile phones can be eavesdropped on.
The public availability of the software - dubbed Airprobe -- means that anyone with the right hardware can snoop on other peoples' calls unless the target telecom provider has deployed a patch that was standardized about two years ago by the GSMA, the trade association representing GSM (Global System for Mobile Communications) providers, including AT&T and T-Mobile in the U.S.
Most telecom providers have not patched their systems, said cryptography expert Karsten Nohl.
"This talk will be a reminder to this industry to please implement these security measures because now customers can test whether they've patched the system or not," he told CNET in an interview shortly before his presentation. "Now you can listen in on a strangers' phone calls with very little effort."
An earlier incarnation of Airprobe was incomplete so Nohl and others worked to make it usable, he said.
Airprobe offers the ability to record and decode GSM calls. When combined with a set of cryptographic tools called Kraken, which were released last week, "even encrypted calls and text messages can be decoded," he said.
To test phones for interception capability you need: the Airprobe software and a computer; a programmable radio for the computer, which costs about $1,000; access to cryptographic rainbow tables that provide the codes for cracking GSM crypto (another Nohl project); and the Kraken tool for cracking the A5/1 crypto used in GSM, Nohl said.
More information about the tool and the privacy issues is on the Security Research Labs Web site.
