Nokia deploys deploy a liquid-cooled base station

Nokia, Elisa and Efore have commercially deployed a liquid-cooled base station system in an apartment building in Helsinki, Finland. Heat emitted by the base station is redirected into the building.

The liquid-cooled base station was made at Nokia's Oulu facility in Finland and the liquid-cooled power system was developed by power supplier Efore, with Elisa deploying the base station in Helsinki.

By eliminating the need for air conditioning and fans, Nokia Bell Labs said liquid cooling for a base station can deliver a reduction of up 80.percent in CO2 emissions and up to 30 percent in energy operating expenses.

Pekka Sundström, head of the Elisa customer team at Nokia, said: "Nokia and Nokia Bell Labs have conducted extensive research and testing to explore the possibilities of using a liquid-cooled base station in an operator's network. This first commercial deployment will enable us to understand the real-world benefits for customers such as Elisa as they transition toward 5G, and how the system can be implemented on a wider scale to help reduce the environmental impact of information and communications technology. We continue to explore ways of introducing efficiencies and reducing emissions across our portfolio, and this project marks a significant step in that journey."

NTT DOCOMO Base Stations Avoid On-Peak Electricity Consumption

NTT DOCOMO is testing a base station with dual power-source control technology that uses more than 95% reduced-impact (solar and off-peak) electricity.

The idea is to avoid the use of on-peak electricity as much as possible. The proto type base station leverages lithium-ion batteries to store excess solar electricity generated during the daytime and off-peak electricity generated during the nighttime. Stored electricity is used as the primary source between dusk—once solar-electricity generation becomes unavailable—and 11pm, when off-peak electricity becomes available.

ZTE Tests Massive MIMO Pre-5G Base Station

ZTE announced pre-commercial field testing of a next gen base station leveraging Massive MIMO (multiple input multiple output) that sets new records in single-carrier transmission capacity and spectral efficiency.

ZTE said its proprietary, pre-5G, multi-user/multi-stream spatial multiplexing technology has demonstrated peak data throughput that is more than three times that of traditional base stations, and average data throughput that exceeds conventional systems by at least five times. Testing is done with conventional 4G handsets.

Based on ZTE’s self-developed baseband processor chipset, the Massive MIMO base station uses a frontal area similar to existing 8-antennas. Integrating antennas, base station units and RFs in one module, ZTE’s Massive MIMO base station uses only one-third of the installation space of traditional systems, lowering operating costs and total cost ownership of operators.

“Being a pre-5G technology, ZTE’s Massive MIMO solution is delivering exponential advances to 4G networks without modifying existing air interfaces, making it possible for carriers to provide a 5G-like user experience on existing 4G handsets in an accelerated timeframe,” said Dr. Xiang Jiying, Chief Scientist of ZTE. “ZTE successfully overcame the challenge of doing multi-user and multi-stream spatial multiplexing in a scattered-signal environment, clearing the main hurdle in the development of Massive MIMO technology.”

NSN Enhances its Single RAN

Nokia Solutions and Networks announced six enhancements for its Single RAN (radio access network) Advanced portfolio:

  • Single RAN releases will support GSM, WCDMA and LTE deployments. The New Single RAN Advanced will align availability of three separate software releases, making it easy to build, operate and maintain NSN Single RAN Advanced networks.
  • Flexi Multiradio 10 Base Station 6 x 60W radio frequency module enables a compact three-sector site with LTE MIMO 2x2 using just one radio frequency (RF) hardware unit instead of two 3-pipe modules. It provides 360W total RF output power, the highest in market, for better end user experience. With this, operators can now deploy 1800 MHz LTE/GSM refarming and RF sharing using half the number of modules.
  • Expansion sub-module for increasing RF connectivity of the Flexi Multiradio 10 Base Station. This new sub-module supports three times more RF ports compared to earlier models, enabling operators to meet their refarming and RF sharing needs with less hardware.
  • Smart Dual Beam (SDB) application software for Liquid Radio GSM Software Suite brings an intelligent new way to build three-sector GSM sites. This enables operators to either benefit from 50% more GSM capacity in their existing spectrum and base station sites, or provide 20% more spectrum for HSPA/LTE deployments.
  • Common Base Station Operations, Administration and Maintenance entity, supported by NSN’s NetAct 8, for sites with GSM, WCDMA and LTE base stations. It replaces three separate entities with one, making it simpler to build, operate and maintain base station sites.
  • Improved common IP backhaul solution with a new single transport function to support single site deployments. On the transport layer, GSM, WCDMA and LTE base station sites can now appear as one IP host, which improves flexibility in IP addressing, QoS and IP security, and simplifies the IP transport backhaul implementation and maintenance process.

“Radio access networks are becoming increasingly complex with LTE services provided alongside GSM and WCDMA services, and new frequency bands, as well as IP-based transport for LTE being added to existing backhaul network,” said Kimmo Virkki, vice president, Single RAN Business Product Management at NSN. “Running three different networks simultaneously often means rising costs, and compromised performance given the increased risk of error. NSN’s Single RAN Advanced cuts through this complexity by running GSM, HSPA and LTE technologies on shared multi-purpose hardware. Our latest features simplify base station sites and their operations, slashing costs and freeing up 55% of the spectrum for HSPA/LTE refarming.”
