Nokia Siemens Launches Low-energy Base Stations


Most of the energy in a typical telecommunication network is consumed by the wireless network's base station site. In response to this, Nokia Siemens Networks says that it is announcing offerings that dramatically improve the energy efficiency of its wireless networks, particularly the base stations and base station sites.
"The Energy Efficiency solution makes good green business sense," said Ari Lehtoranta, head of the Radio Access business unit at Nokia Siemens Networks. "By bringing state-of-the art products and software together with our Services portfolio for operators, we can reduce adverse environmental impact while also generating considerable cost savings for our operator customers."
The four main elements of the solution are:
Minimizing the number of base station sites;
Minimizing the need for air conditioning to cool the sites;
Using the latest base station technology;
Deploying software features that optimize the use of radio access for wireless communications.
Nokia Siemens Networks says that the energy consumption of a base station site can be reduced by up to 70 percent with its Energy Efficiency solution.
Nokia Siemens Networks says that it has achieved energy consumption levels of 800W and 500W respectively for typical GSM and WCDMA base stations. Going forward, the company has set even more ambitious targets: to further reduce the energy consumption of its GSM and WCDMA base stations to the 650W and 300W respectively by 2010.
Building a network with a minimum number of base station sites increases energy efficiency, and intelligent network planning is critical for identifying optimum site locations. The Nokia Siemens Networks Energy Efficiency solution uses software features to increase coverage, thus minimizing the number of required base station sites. The solutions also take advantage of Nokia Siemens Networks planning products to create new types of sites in previously non-viable locations. The Nokia Siemens Networks Flexi Base station, for example, makes it possible for operators to locate complete base stations in places and positions where conventional base stations cannot be located due to limitations on size and weight.
Traditional base station sites are located indoors, where the typical temperature of 25 Celsius is maintained with high energy-consuming air conditioning. By increasing the ambient temperature to up to 40 Celsius, energy consumption can be reduced by up to 30 percent in existing base station equipment.
Nokia Siemens Networks utilizes a wide range of software features to improve base station energy efficiency by balancing consumption according to load. For example, because nighttime base-station traffic is much lower than during peak daytime hours, part of the base station can be shut down or its capacity can be set on power save mode at night. This is handled seamlessly by Nokia Siemens Networks' intelligent network management solution, the NetAct Service Quality Manager. By leveraging the latest innovations in its software solutions, Nokia Siemens Network is helping operators reduce costs by lowering the energy consumption of base stations during off-peak hours -- without any impact on service levels for users of the network

Nokia Siemens May Lose Indian Gsm Contract to Ericsson

Local reports are suggesting that Ericsson could win the entire GSM network tender from India's BSNL as Nokia Siemens Networks (NSN) has not yet formally agreed to the terms from the company. The company had planned to split the 22.75 million GSM lines contract 60:40 between Ericsson and NSN. Ericsson's current allocation is worth around US$1.3 billion while NSN's is worth around US$954 million.
Nokia Siemens did originally tender at a higher cost than Ericsson, hence the smaller share of the tender - but is required to match Ericsson's price if it wants to take up the contract.
An unnamed BSNL executive told The Economic Times that if NSN failed to pick up the purchase orders within the next couple of days, another option would be to float a fresh tender.
When asked if BSNL would award the entire contract to Ericsson, BSNL chairman and managing director Kuldeep Goyal told the newspaper "I hope they (NSN) come around. However, if they do not agree, then we will have to explore other options".
BSNL's tender has been mired in controversy ever since it was sent for RFP last year. Initially the tender was for a massive 45 million lines, but the government blocked this and it was shrunk to just under 23 million lines. Then arguments with Motorola who claimed to have bid lower than Ericsson for the tender, but was disqualified from competing on technical grounds.
Under the terms of the final award, Ericsson bid the lowest figure - reported to be about US$91 per line. Nokia - prior to the infrastructure merger with Siemens had bid around US$177, with a significantly higher figure reported from Siemens. The merged company may be having difficulty in pulling down its costs to the level offered by Ericsson.

70 Percent of Daily Engineering Work is Wasted




A survey carried out on behalf of the network optimisation services provider, Actix has reported that mobile operators are wasting 70 per cent of engineering time every day because they don't have access to the right network management information, according to its recent survey of network engineers. The survey results highlight that engineers are wasting nearly three quarters of their day trying to access network status information, which is complicated and time consuming.
Many of the engineers surveyed said they had to access multiple, disparate systems, which lack automation, visibility, prioritization and integration between tools.
In major mobile networks it is typical for engineers to spend most of their day trying to manually piece together a complete picture of the network by accessing numerous screens of information. Without prioritization or automation, engineers are simply working through a long list of faults, some of which could be automated or de-prioritized to free up engineering resource to focus on critical, service-affecting faults.
Actix says that over 5,000 engineers from more than 200 operators globally use its software every day to improve their wireless operations.
