When it comes to the availability and quality of wireless voice and data communication services, the high coverage requirements apply just as much inside buildings as they do outside. With millions of app-based internet, data and voice services running on smart phones, tablets and notebooks, subscribers are increasingly expecting an unlimited, seamless connectivity across 2G, 3G or 4G networks – making mobile connectivity within public buildings such as shopping malls, stadiums, railway stations, airports, convention and exhibition centers and hospitals a must.

The shielding effect of a building’s front and structure can have a detrimental impact on radio signals and is often the reason behind insufficient service quality – in such cases additional technical measures are indispensable.

The SENCITY Rondo antenna, the latest addition to HUBER+SUHNER’s IBC/DAS portfolio, responds exactly to the highest standards of the crucial PIM (Passive Intermodulation) characteristics for DAS (Distributed Antenna Systems) and IBC (in-building coverage) systems, and is meeting the ever-increasing market demands for indoor coverage of mobile voice and data traffic required to cover an ever wider range of applications and services. Also included in the SENCITY range is the SENCITY Cube MIMO antenna designed for directional radiation and ideal for small areas such as corridors or rooms.

One antenna for almost all LTE frequencies

Due to the massive and increasing demand in data traffic, future-proof multiband and multi-operator network technology will be deployed. This will support a wide range of communications technologies, including GSM (Global System for Mobile Communications), W-CDMA (Wideband Code Division Multiple Access), UMTS (Universal Mobile Telecommunications Systems) or LTE (Long Term Evolution).

The SENCITY Rondo, with its omnidirectional pattern and high gain characteristics, guarantees coverage across large areas. This, coupled with its multiband 698-3800 MHz range, means the SENCITY Rondo covers almost all LTE frequency bands and beyond.

The wide coverage properties of the SENCITY Rondo mean that it is not necessary to install separate antennas for individual applications, which can be very costly and space-intensive. This facilitates the integration of DAS in existing buildings at a reasonable cost for materials and installation and with the added benefit of aesthetic and unobtrusive design.

Discreet enough for any architectural design

The SENCITY Rondo combines an electrically efficient MIMO antenna with an attractive design suitable for many different architectural forms. Its design is neutral, so that architects can concentrate on styling the building with traditional and modern design elements, leaving the antennas in the background and almost unnoticeable.

Beside the classic below-tile mounting possibility, the SENCITY Rondo has four further mounting options for a range of situations and architectural styles including below hard ceiling, above the ceiling, through ceiling tile and completely recessed through ceiling tile. All five mounting options use the same bracket. The range of options offers the customer the flexibility to make the communication system as discreet as he likes, with the last option making the antenna ultra-thin and only protruding from the ceiling for 1mm.

The 2×2 MIMO and 4×4 MIMO are fitted in the same housing, making it possible to re-use the mounting brackets or the mounting socket in the building for the next generation upgrade. This will continue to be the case when the LTE 600 version is launched.

The same concept, this time with a rectangular shape, has been applied to SENCITY Cube MIMO which is the corresponding antenna for directional radiation, ideal to cover corridors or rooms where the energy is needed in certain areas. The focus on the electrical performance has resulted in a very stable PIM design, an optimal directional diagram and high gain.

For added convenience, the cable can be passed through the wall behind the antenna or it can be hidden in the Plenum space, so that it is almost invisible.

The two antennas are equipped with standard N connectors on the pig tails. In addition 4.3-10 and 4.1-9.5 connectors are also available. SIS antennas can also be supplied in the same shape, to match installations where MIMO or SISO are needed in the same building.

One solution – many options for the future

With the implementation of dedicated solutions, such as HUBER+SUHNER’s extensive portfolio of IBC and DAS indoor antennas, the internal coverage required can be achieved in every situation – with the opportunity for additional voice and data channels capacity to be created as required. In the case of DAS, the appropriate use of active and passive system components results in guaranteed seamless availability of the services across floors and individual rooms.

The use of such broadband system components offers good investment protection to the customer and guarantees sustainable flexibility for future expansion. More information hubersuhner.com
