LTE rykker ind på 1800 MHz frekvensbåndet

Renesas Mobile vil i samarbejde med Nokia Siemens Networks demonstrere  'end-to-end' LTE-løsning, der opererer i 1800 MHz området (in english).

Renesas Mobile Corp., a supplier of advanced cellular semiconductor solutions and platforms, has announced an end-to-end Long Term Evolution (LTE) demonstration, using the 1800 Megahertz (MHz) spectrum, together with Nokia Siemens Networks at Mobile World Congress 2011 from February 14-17, 2011.

The demonstration features commercial base station equipment from Nokia Siemens Networks and Renesas Mobile’s test platform using a highly integrated LTE triple-mode modem. The companies’ collaboration on LTE at 1800MHz (LTE1800) fully conforms to 3GPP (Third Generation Partnership Project) radio performance requirements, and illustrates that LTE1800 will soon be made commercially available.
       
Much of the initial focus in LTE development has been in the use of newly allocated frequency bands and has overlooked the importance of reusing existing spectrum. The 1800MHz band, which is widely used today for GSM, is becoming a key band for LTE deployments.

It is particularly well suited to be used for high capacity and high throughput broadband wireless networks, as many operators have significant bandwidth on the band, allowing 20MHz configurations.
       
Renesas Mobile and Nokia Siemens Networks have been among the first to prove the technical feasibility of LTE technology at 1800MHz in an end-to-end configuration covering network and user equipment.

- The LTE 1800MHz frequency band combines good coverage with large bandwidth, says  Thorsten Robrecht, head of Network Systems product management, Nokia Siemens Networks.

- It will be extremely important for LTE adoption, especially in countries where additional spectrum for LTE will not be available. We are now demonstrating LTE1800 with Renesas Mobile to show what a cost-effective route to commercial LTE it is. This continues our close co-operation to ensure a smooth market introduction. 
       
- A deep, long-term relationship with leading infrastructure vendors such as Nokia Siemens Networks is very important to ensure that our roadmaps and technology deployment plans are aligned, says  Heikki Tenhunen, Senior Vice President, Renesas Mobile Corporation.

- We have been working closely with Nokia Siemens Networks for many years to bring technology - including LTE1800 - to market that benefits consumers and operators.
