Samsung 5G development "several hundred times faster" than LTE

LTE may only be wiping its feet on the proverbial doormat, and yet Samsung has already announced a significant breakthrough in the development of 5G mobile communications. The company says this will pave the way for next-generation mobile networks offering transmission speeds in the tens of gigabits per second – hundreds of times faster than LTE.

Samsung Electronics has developed an adaptive array transceiver capable of transmitting data at a rate of 1.056 Gbit/s at a range of up to 2 km (1.2 miles) in the tricky millimeter waveband. The millimeter band, or extremely high frequency band, is not normally associated with long-distance communications due to signal attenuation in the atmosphere and in rainfall.

At 28 GHz, Samsung's technology is operating just outside of the band normally considered the millimeter band, which ranges from 30 to 300 GHz. At these frequencies, electromagnetic radiation has wavelength of between 1 and 10 mm, hence the name. The millimeter band has long been recognized as offering the potential bandwidth to revolutionize telecommunications, with the broader range of frequencies available that would allow such high bandwidths at the commercial scale. The same principle applies here.

Samsung says that its 64-antennae transceiver, which transmitted data at 1.056 Gbit/s, "can be a viable solution for overcoming the radio propagation loss at millimeter-wave bands," and would allow the transmission of 3D films and games, ultra HD video and, intriguingly, "remote medical services."

The company predicts that 5G technologies may not be very far away, citing the European Commission's investment to commercialize them by 2020.

GSA confirms 347 LTE user devices, with smartphones and tablets leading growth

April 4, 2012: An update to the ‘Status of the LTE Ecosystem’ report published this week by the GSA (Global mobile Suppliers Association) confirms that 63 manufacturers have announced 347 LTE-enabled user devices.
Around 250 new LTE user devices have been announced over the past year.
Alan Hadden, President of the GSA, said: “The main growth trend in 2012 so far is the launch of LTE-capable smartphones and tablets. We report that the number of smartphones has increased by one third since January 2012. The number of LTE-capable tablets increased 72% in the same period.“
According to the GSA report, there are 64 LTE smartphones and 31 tablets, including frequency and carrier variants.
Research for the report considered user devices for FDD and TDD modes, form factors, operating frequencies, and the fallback technologies which are supported when customers move outside the LTE coverage areas (i.e. ability to access HSPA, HSPA+, DC-HSPA+, EV-DO, or TD-SCDMA systems).
347 LTE devices breakdown by form factor:

• 41 Modules
• 31 Tablets
• 13 Notebooks
• 2 PC Cards
• 1 Femtocell
• 64 Smartphones
• 131 Routers
• 64 Dongles

Note that certain products are carrier or country specific and are not available in all markets.
217 LTE devices also operate on either HSPA, HSPA+ or 42 Mbps DC-HSPA+ networks. Within this figure, 91 LTE devices support 42 Mbps HSPA+ technology.
108 LTE devices support EV-DO networks.
The report also considered the availability of devices by frequency band and support of the likely required combinations. The report findings are summarized below for the main LTE bands:

• 700 MHz (US Digital Dividend, various bands) 170 devices
• 800 MHz (EU Digital Dividend, Band 20) 72 devices
• 1800 MHz (Band 3) 75 devices
• 2600 MHz (Band 7) 94 devices
• 800/1800/2600 MHz 57 devices
• AWS (Band 4) 72 devices

The majority of LTE user devices today support the 700 MHz band where LTE networks and services are developing fastest, especially in North America. As LTE network rollouts accelerate in other regions, particularly in Europe where operators are primarily using 2600 MHz, 1800 MHz and 800 MHz digital dividend spectrum, in many cases using all three bands, manufacturers are responding with products for these markets. For example, the number of user devices capable of operating in 2600 MHz spectrum (band 7) has increased by 44% since January 2012. The choice of LTE1800 (band 3) devices is rapidly expanding as more operators focus on the opportunities from deploying LTE systems in 1800 MHz spectrum. There are now 75 LTE1800 user devices, which is 50% higher than GSA reported in January 2012. [continues after image]

The range of LTE TDD devices is also expanding as operators in all regions are preparing for a wave of commercial launches of TDD systems. 53 LTE TDD capable devices are included in the 347 total figure.

Cloud RAN

Distributed Node-B architecture called Cloud Radio Access Network (C-RAN) is the new paradigm in base stations architecture that aims to reduce the number of cell sites while increasing the base station deployment density bypassing some of the zoning and construction hurdles to brining up new sites on-air. Metro cities like NY, LA and SFO already have a high density of Cell towers. As LTE and more complex wireless technologies are being deployed – would it not make sense to re-use and harness the existing infrastructure?
The concept of the Cloud RAN comes with a new architecture that breaks down the base station into a Base Unit (BU) – a digital unit that implements the MAC PHY and AAS (Antenna Array System) functionality, and the Remote Radio Head (RRH) that obtains the digital (optical) signals, converts digital signals to analog, amplifies the power, and sends the actual transmission. By making the RRH an active unit capable of converting from analog to digital, operators can now place numerous BUs in a single geographical point while distributing the RRUs according to the RF plans. The RRH becomes an intelligent antenna array which not only submits RF signals but also handles the conversion between digital and modular data. New RRH can also support multiple cellular generation (2G, 3G and LTE) eliminating the need for multiple antennas.
The Cloud RAN lowers operating expenses and simplifies the deployment process. By centralizing all the active electronics of multiple cell sites, at one location (aka the “Base Station Server”), energy, real-estate and security costs are minimized. The RRH can be mounted outdoor or indoor – on poles, sides of buildings or anywhere a power and a broadband connection exist, making installation less costly and easier. The RRH is typically connected using fiber to the BU, creating cloud-like radio access network topology.  This topology saves costs both during the installation and later on technology upgrades for both software as well as hardware saving the operators millions of dollars in CAPEX/OPEX.

4G Brings New Opportunities

Next-generation LTE technology has been making its presence felt across the Asia Pacific region as mobile
operators progressively roll out commercial services.At present, LTE services are largely limited to
USB modems due to a lack of compatible mobile devices. However, we expect the situation to begin
changing in 2012, and the large-scale launch of 4G smartphones and tablet computers should herald a new
generation of mobile VAS.

Besides services such as video streaming and video conferencing, the machine-to-machine (M2M) market
could be one area that could receive more attention from Asian companies following the launch of LTE
services. M2M technologies refer to the ability of different devices to communicate and relay information.
They can be used in areas such as smart utility metering, ehealth, telematics and digital billboards, and
Western European mobile operators and M2M vendors have been actively developing the market to pursue
greater adoption.The Philippines' Globe Telecom launched its first M2M service - a GPS vehicle tracking system - in 2008 and expanded its portfolio further in August 2011 to encompass monitoring of fixed assets, surveillance and security, as well as tracking of various objects ranging from vending machines to tanks.

Self-Organising Network (SON)

The vision of self-organizing networks (SON), which is in line with the views of 3GPP (3rd Generation Partnership Project) and the NGMN (Next Generation Mobile Networks) group, is that future radio access networks needs to be easier to plan, configure, manage, optimize and heal compared to how it used to be.SON has been codified by the 3GPP Release 8 specifications in a series of standards including 36.902^\ as well as public white papers outlining use cases from the NGMN.

The first technology making use of SON features will be UMTS Long Term Evolution. The LTE specification inherently supports SON features like Automatic Neighbor Relation (ANR) detection, which is the 3GPP LTE Rel. 8 flagship feature.
Newly added base stations should be self-configured in line with a ‘plug-and-play’ paradigm, while all operational base stations will regularly self-optimize parameters and algorithmic behavior in response to observed network performance and radio conditions. Furthermore, self-healing mechanisms can be triggered to temporarily compensate for a detected equipment outage, while awaiting a more permanent solution.
