SPINNER GmbH solutions for LTE

The  LTE (Long Term Evolution) project has developed a new high-performance interface for cellular mobile communications systems.

 This is the last step towards the 4th generation (4G) mobile phone focusing on increasing capacity and speed in networks. This technology has been directed towards the adoption of the All-IP from its initial conception.
The first public service available with LTE technology available for Telia-Sonera in Stockholm (Ericsson) and Oslo (Huawei) since December 2009. In August 2009 the European Commission announced an investment of 18 million euros for the joint development of LTE in 4G and called LTE Advanced.
The main benefits of LTE are its large throughput, low latency (<10ms), plug and play, FDD and TDD in the same platform with OFDM, enhanced end user experience and simplified architecture, which results in low operating cost. LTE also supports the transfer to sites with old technologies like GSM, cdmaOne, UMTS or CDMA2000.


Combination
In addition to its well-known connectors, Spinner offers a wide range of products applied to this new standard: combiners, filters and splitters. These components are suitable for installation indoors or mast.
Some important components are listed below:

1 .- Intra-band combiners: GSM900, DCS1800 and UMTS. (Figure 1)

2 .- Multi-band Combiners: DCS + UMTS + LTE (2496-2690MHz) + LTE GSM900, DCS + UMTS, GSM900 + DCS + UMTS, etc.. (Figure 2). 

3 .- Hybrid Couplers 3dB: allow diplexión (sum) of several economic carriers. Physically, consisting two lines near magnetic coupling. Are broadband 800-2700MHz and will allow the combination of 2 to 4 inputs. (Figure 3).

4 .- Power splitters: 3dB symmetrical and asymmetrical 4,7, 6,7, 8, 10, 13, 15, 20 and 30 dB and from 2 to 4 outputs. Are broadband 800-2700MHz and mix ideal for LTE + GSM / DCS or UMTS. (Figure 4).
 

5 .- Artificial Loads: necessary in all types of telecommunication facilities. Typically for these applications are used from 50 to 200W. (Figure 5)
 

6 .- Break and DC Bias Tee used in the tele-equipment supply, either DC injection or extraction. (Figures 6 and 7).

Ready to MNCS
Spinner GmbH for years been offering their proprietary system MNCS (Mobile Network Combining System MNCS ©) a modular solution for safe and efficient stacking modules combined.
MNCS allows several operators sharing a single antenna system with minimal attenuation and a very low level of PIM guaranteed.
These combine work with frequencies from 380 to 2700MHz, including all communications bands in common use including 3G and LTE.
All system components are inserted into a rack of 19 "sleek, compact form. (Figure 8). They are easy to monitor, expand and maintain. 7).
