SmartPlex Multi-Protocol Dual-Band Combiner 31 March 2010

The SmartPlex® models 782 10900 (BTS) / 782 10901 (ANT) are a compact series of intelligent multi-protocol dual-band combiners. The SmartPlex® combines the frequency ranges 380 – 960 MHz and 1710 – 2690 MHz while providing a very low insertion loss and allowing high input power. They can be powered either via a CCU or a BTS.

Infrastructure sharing is a necessity for many wireless carriers. Operators faced with feedline sharing must contend with the issue of varying communication protocols between antenna line devices (TMA’s, RET actuators, etc.) and base station equipment, often from multiple manufacturers.
Kathrein’s new SmartPlex® product family of combiners offer a cost effective solution for enabling simultaneous multi-protocol communication transparency for CWA / AISG1.1 / AISG 2.0 / 3GPP and other vendor specific protocols while allowing RF feeder cable sharing.

Operators implementing dual-band combiners no longer need to select from models with DC-bypass variants, which would have to be considered when using conventional combiners, because the SmartPlex® offers dynamic DC-bypass functionality. SmartPlex® also intuitively provides the correct DC supply voltage at each mast-head device while managing multiple BTS DC power supplies.

Altobridge Cutting the cost of Transmission - For Everyone  14 August 2008

“Despite significant advances to drive down capital costs for Mobile Network Operators (MNOs), several key challenges still remain before the digital divide is truly bridged, with transmission costs standing out as the No.1 barrier.”

Although more subscribers in more areas can now be connected and are reaping the
benefits that mobile communications brings, the above quote from Mike Fitzgerald, CEO
of leading wireless application solution provider, Altobridge, highlights the fact that high transmission costs have hindered the delivery of communications to a huge number of people around the world for too long.

Fitzgerald continued, “The lower our industry can get transmission costs, the more
subscribers we can connect, and the more remote communities and people we can bridge and bring into the connected world. Transmission capacity is becoming a rare and expensive commodity and as we introduce new generations of technology, more and more capacity is being demanded.”

For his part, Mike Fitzgerald has headed the pioneering R&D efforts of Altobridge,
which have truly cut the cost of communications, to, from and between mobile
subscribers. The company has invested significant resources over the past five years
resulting in several major technology breakthroughs, which, in Fitzgerald’s own words,
“have had a measurable impact on mobile operators’ bottom lines”.

Two of these breakthroughs, the company’s Local Connectivity solution and its Split
Communications Architecture, are poised to have major impact on networks, globally.

“We have developed what we term our Local Connectivity solution,” said Fitzgerald,
“through which it is possible to keep local traffic local, therefore removing the cost of
traffic being backhauled, back and forth across the network. We achieve this without
impacting the standard signaling protocols of the core network and, with up to 70% of
traffic being local in emerging markets, this breakthrough is hugely important.”

CeBIT Australia 2008, 20 - 22nd May                                        23 April 2008

Kathrein demonstrated their latest range of antennas and associated equipment.

Some examples of the actual products on display included the new WiMax antennas, fully integrated RET antennas, simulated UMTS 900 site incorporating dual band 900 macro antenna system, triplexed DTMA for UMTS 2100 with 900/1800 bypass, mast with 80010492 (new tripleband) and 80010439 (new high gain), mast with 80010486 (new dualband) and 80010504 (new multiband) and new tripleband combiner.

Kathrein 900 MHz antenna                                                  6 February 2008

Kathrein has developed an XX-Pol (DUAL 900) antenna with an extended frequency

range of 824 to 960 MHz.  The new antennas feature a small-dimensional design.

Instead of requiring 520 mm for two 900 MHz antennas side by side, the solution can be fitted into a singleradome, using a width of only 360 mm. All the antennas are fitted with an RET interface and can be controlled and monitored via the Kathrein RET system(CCU/ASM). 

Kathrein is also offering a DTMA 900 with a gain value of 12-32 dB, which is also compatible with AISG 2.0. This means the DTMA can also be fully monitored via the

Kathrein RET system.
