Interference to your 3G and 4G services?

Comments Off on Interference to your 3G and 4G services?


newBetter Data with our New Bandstop Filter

With more and more of our clients having problems with LTE and 3G interference from different RF sources, this new filter helps prevent any interference from the frequency band 1983.1 – 1990 MHz.

Interference Prevention with Customisation

We can customise any Passband and Stopband for your case with 30 to 50 dB rejection suiting your needs. Normally 30dB rejection is adequate in most cases, meaning that the interference is supressed to at least 20 times lower in power. This will improve voice and data significantly, bring more traffic, more revenue and happier customers in the network with improved LOYALTY!

Invisible LTE Antenna for ALL frequencies

December 29th, 2011
Comments Off on Invisible LTE Antenna for ALL frequencies

Our Invisible Antenna  has recently been upgraded to cover all 4G/LTE frequencies, making it a truly global choice for all LTE systems.

Invisible LTE Antenna (datasheet)

Why is it Invisible ?

Our invisible antenna is one of our best selling items. This is mounted from above the false ceiling and only the ‘smoke detector’ shape is seen by the users. Making the antenna invisible

How does it help Data service for 3G / 4G?

This actually allows you to have the dipole below the ceiling for maximum Data performance, while it is so low profile that does not make users think that there is an antenna. Since the dipole is below ceiling, it will not be blocked by builder materials. These materials are often made of metal which reduces available radio signal strength and caused reflection and difraction. By using the Invisible Antenna, the maximum Signal to Noise Ratio and Signal Strength are acieved to allow best  Voice Quality and Data Throughput.

Why is the Invisible Antenna best for 3G / 4G?

We have now upgraded this Invisible Antenna to support 700 MHz to 6000 MHz, covering the 4G / LTE frequencies. By using this antenna, the building is future proof. If an upgrade is required you are ensured that the antenna can continue be used to support the next technology.

New Generation Smart Elevator Solutions SES

August 11th, 2009
Comments Off on New Generation Smart Elevator Solutions SES

New SES

We are changing with the world. Having introduced our Smart Elevator Solution SES we proudly introduce our new generation product.

IMG_9344Integrated Antenna

We have integrated it with an internal built-in service antenna. This gives extra space savings inside Lift Cars and make it easy to install.

Install Inside Lift Cars – Easy Maintainenance

Our first generation SES was to be installed on top of lift cars. The stylish casing of the new SES allows you to install it  inside. This makes it much easier for maintenance as access is now easily possible without interrupting lift services.

This new generation SES marks the innovation effort we continuously made.

Multiband

We still maintain single band and multi band options for normal bands Tetra / CDMA / GSM / DCS / PCS / WCDMA.

Auto Setup / Diagnostics

Upon power up, the unit runs self diagnostics for apporpriate donor signal and the fully auto ALC will adjust output power to a level optimum for performance.

Please contact us for details.
