The Indian Telecom sector is set to receive a strong boost at 40 billion dollars being invested into its infrastructure. This is necessary do to the quantity of new mobile phone users each year. India connects almost 2 million new cell phone users yearly. With that kind of increase the 40 billion dollars makes sense.
India has strong growth in its technology sector and do to the rapid growth of its emerging economy, India not only has money to invest, but the necessity to do it.
The wireless technology WiMax would be an alternative to Internet access via DSL. The technique works, now need a few more bureaucratic hurdles are cleared away.
Everywhere online: Wimax could fulfill this dream
The area around Skelleftea in northern Sweden is sparsely populated. Small villages and individual farms are lost in the barren countryside 200 kilometers south of the Arctic Circle. There is not much here, but still a damn fast internet connection.
Here, where the wiring of the great community over 7000 square kilometers would devour tons of money, which currently stand performing antennas for broadband data transmission in the sky: No Hill, no high-rise far and wide – ideal conditions for the new wireless technology WiMAX (Worldwide Interoperability for Microwave Access) , a kind of super-hot tub. Since last September, the Swedish provider Mobile City operates together with the chip giant Intel, the test facility.
30 budget initially participated in the test and have been with 8 megabits (Mbps) transfer rate (10-fold favorably DSL speed) Internet connection, they just need an external antenna.
“A free broadband with WiMax in the region around one seventh of that what you would spend on a cable,” says Goran Eriksson, CEO of Mobile City. Currently, only 23 percent of Swedes Internet via cable. The rest are potential Wimax customers.
Although the proverbial last mile in Germany is not quite as long as in northern Sweden, but even in this so WiMAX could be a success. The theoretically possible Wimax range of 50 kilometers at speeds of 70 Mbps, however, are the ideal case, and only accessible with a line of sight. For this, a directional antenna is required and a fixed location of the recipient.
For mobile devices it looks quite different: “Even Wimax is governed by the laws of physics,” says Wolfgang Wood, head of the “Wireless network access” at Alcatel. The peak levels of a stationary line of sight can be reached by mobile devices do not, because melting at “non-Lineof-sight connections,” the great distances swiftly along: “In buildings and in closely built-up cities typically ranges lie closer to 600 meters.” Spot the Metro, which is supplied with a central antenna, all laptops of a city with an Internet connection, give it even with Wimax.
WiMAX was originally planned as a standard microwave line of sight. But then the WiMAX Forum with 170 participants, including companies such as AT & T has taken Intel, Nokia and Siemens, is the provision of portable devices in the eye. Because multiple reflections, the lack of directivity of the antennas and walls attenuate the signal, are necessary for mobile applications, however, more robust modulation technique. The correspondingly revised Wimax specifications are still in the standardization phase.
In the stationary technique has long been furnished proof of their suitability. “We already sell on Wimax technology-based facilities overseas,” said Alcatel-expert wood. In Chile and Brazil supplied Wimax entire regions, in France, the Vendée department is equipped with the wireless coverage in Hong Kong, almost one million users surfing via WiMAX. All installations are however still “pre-WiMax”, without any international certificate and mutually incompatible.
That should still change the course of this year. The common standard is ready, only some details are still pending. Although this is resolved, is the conquest of the mass market really nothing to prevent. Particularly, the chip giant Intel is one of the most ardent supporters, and has put forward an ambitious schedule: According to the permanently installed outdoor antenna (IEEE 802.16a) later this year, smaller stationary indoor antennas allow reception of Wimax (IEEE 802.16 Rev d) from about 2007 could be mobile WiMAX devices such as laptops, PDAs or cell phones come on the market (IEEE 802.16 e). A specially developed chip for WiMax – “Rosedale” Specified – Intel has already introduced last year.
This seems to be all hardware on the way, and in Germany is not even clear who may even spark via Wimax. “So far we have awarded ten licenses for Wimax trial,” Mohl says Bernhard, who is responsible for the regulatory authority (RegTP) for the allocation process of Wimax spectrum.
Even the type of licensing is still open to debate is the so-called general assignment. Then each provider would like today to WLAN without special authorization to operate a WiMAX-link. “That would go only with a compulsory registration, because the frequencies are scarce,” said Mohl. “In a region can only handle a few Wimax stations are operated.” Alternatively, the individual allotment out of the question, shall, in the RegTP approval for certain regions.
“We are thinking also about a Licensinglight that simplifies the assignment. It would be interested in the case of spectrum scarcity by competing claims among themselves,” says Mann RegTP Mohl. What kind of award or whether and what conditions constitute Wimax approval will be connected, is currently still open. Currently has more than 50 comments Moehl of the consultation process on the desktop.
Requirements exist in Germany. Many areas in the countryside are not provided by Telekom for cost reasons with DSL. Even regions that have been fitted in the 90′s with fiber optic technology, practically the whole of the East, do not get a DSL broadband coverage, because DSL is a copper technology.
In these areas, Michael Friedewald looks at the Fraunhofer Institute for Systems and Innovation Research in Karlsruhe, the first locations for the new technology: “For areas without DSL coverage crowd Wimax networks in an almost,” says the researcher. As the author of the study, “Two-ratio high bit-rate wireless networks in future telecommunications markets,” he has investigated the potential of available and future wireless technologies. His conclusion: For the foreseeable future is WiMax, none of the existing networks, either wireless or UMTS, replace or make redundant, but complementary to the existing infrastructure and close the gaps – especially at the DSL map -.
The telecoms company Arcor has completed its laboratory tests with WiMax now and will soon launch the first field trial. Arcor also plans to no coverage in urban areas, but starting in the countryside: “It makes sense, the use of Wimax in communities with 500 to about 2000 inhabitants – this can also financially viable,” says spokesman Michael Arcor Peter. He expects next year with the first commercial offerings. “But we have no plans to build a WiMAX infrastructure in major cities, which would require significant investment.”
In early July, RegTP will publish the results of annotation and specify the type of allocation. “That, however, it must be implemented in instructions,” says Mohl. When the first Wimax stations can go online, it still depends on it, for which procedure chooses RegTP. “At a general assignment that goes faster, the individual allotment takes a little more time. But I expect that we awarded this year, the first Wimax spectrum to broadcasters.
