FAQ

Are Stelladoradus repeaters fully compliant with EU regulations?

Yes.  Our broadband repeaters are the only legal repeaters available in the EU.

Our repeaters have enhanced features that makes them pass all the required European Radio Equipment Directives, (RED). Technically, you still need permission from your mobile operator to use  repeaters, but from a legal and regulatory standpoint, these new repeaters are permitted for sale and installation.

What is the difference between Pro-Monitoring and Self-Monitoring?

Pro-Monitoring:

With Pro monitoring Stella manages your repeater system. Stella will keep the firmware up to date ensuring you benefit from the latest features and performance enhancements. Stella monitors the alerts, and make sure that the system performs optimally over the year. If there are any issues with the system, Stella will try to solve these remotely before the client is even aware of them. However, in the case manual intervention is required, Stella will contact a certified installer who will intervene.

It costs 180€ per year per device(RRP).

Self-Monitoring:

With Self monitoring, the installer is responsible for the management of the system. The alert system is not available for self monitoring, nor is remote firmware updates. However, the installer can still keep an eye on the system remotely use the portal to solve any issues remotely.

It costs 120€ per year per device(RRP).

Is there an extended warranty?

For Pro monitoring customers, we extend our standard 3 year warranty by 2 years. So as long the monitoring contract is maintained each year, Stella will extend it to 5 years.

After 5 years, you can return your product and Stella will offer a 20% reduction on the price of the latest up to date equivalent product.

What is Passive DAS?

Passive DAS means: Passive Distributed Antenna System.

This essentially means that the primary means by which the mobile signal is propagated around the building is through passive elements such as RF cable, splitters and passive antennas, which use no energy at all.

This is by far the simplest, most Eco-friendly and cost effective way to achieve mobile coverage within a building.

Will Stella repeaters work for 5G?

Yes, the latest products from Stella that amplify the 700MHz band (B28) support 5G.  The iR6 is one such product. Furthermore, the future looks bright for owners of Stella repeaters. 5G is now starting to appear at 2100MHz also. This means that if you already have a repeater that amplifies 2100MHz, then soon, you will likely also benefit from 5G.

5G performs even better when it has access to more frequencies. Therefore, to get the best 5G service and best speeds, we recommend repeaters that amplify multiple bands(700Mhz and 2100MHz at a minimum)

 

What is HDR? The new feature in the iRepeater?

HDR stands for High Dynamic Range. This feature is only available in our latest V9 iRepeater (and V5 iLineamp). This new feature means you no longer need to use external attenuators in those high signal power locations. All attenuation can now be done in software. The same applies for the iLineamps, no need to be concerned with attenuators anymore.

What are taps? What are splitters?

Splitter:

A Splitter can be used to introduce a second antenna into the system. However, it adds 3.5dBs of attenuation to the signal. The effect of this 3.5dB loss is to effectively reduce the allowed length of cable to these antennas. Stella specifies that the length of SD400 cable from the repeater to the internal antenna should be no more than 35m. However, if a 2 way splitter is introduced, we recommend to reduce this length to 20m. If a 3 way splitter is used, the length is reduced to 15m.

A splitter (2-way) adds the same loss, 3.5dB to both sides of the split.

Tapper

A tapper (tap), is similar to a splitter in that it allows you to create a split in the cable to introduce a second antenna. however, the loss is not equal to both sides. Instead, one side experiences a loss of 6dB, whereas the other (tap) side experiences a loss of 1.3dB. This can be useful when installing several antennas along the same cable. The taps can equalize the signal power to all the antennas, ensuring that the last antenna on the line still has enough power to be effective.

What is the advantage of a multi-band repeater over a single band repeater?

The more frequency bands a repeater has, the more expensive it is. This is clearly a disadvantage. However, here are all the advantages:

Carrier aggregation:

The more bands you have, the more carrier aggregation (CA) can take place.  CA is when the operator combines 2 or more frequency bands to provide the user with much higher bandwidth and data speeds. One of the core technologies of 5G is CA.

Redundancy:

The more bands you have, the more robust your system will be. Even if one band is compromised,(which can happen alot) your phone can still use the other bands.

Future Proofed:

The more bands you have, the more likely  your system will  function well in the future. The radio frequency landscape changes all the time. Think of the transitions from 2G to 5G. Limiting yourself to just one frequency means you are less likely to benefit from new improvements the operators make to their networks as time goes by.

Covering “Natural Signal”

It is very important that the “natural signal” in your building is “covered” by the repeater. Mobile phones always try to connect to the highest mobile signal that is available. Lets take an example of a house that has installed a single band 900MHz repeater. If 1800MHz is available in this house, even it it is very weak, the phone will bypass the repeater completely, and connect over the weak 1800Mhz signal. By installing a multi-band repeater you can reduce the chance of this happening. ideally we would just install a 6 band repeater and not have to think about this. However, the cost is prohibitive for domestic installation, so a dual or tri-band is a good compromise.

What is MIMO?

MIMO refers to Multiple Input Multiple Output.

It refers to a technology that allows the cellular signal to double or quadruple its bandwidth by utilizing multiple parallel data steams at the same time. It achieves this by using a different polarization for each steam of data. A separate antenna is needed for each stream,  and the angle of each antenna must of offset from each other to align with its particular polarization. Even within just one frequency band, we can have up to 4 parallel steams of MIMO data. This is a big bandwidth enhancement. The learn more read this article.[link]

What are the best signal analyzers (best tools) for repeater installations?

  1. TTI PSA analyzer. This is the best tool for repeater installations and will allow for very professional installations.
  2. CAT – Cable Analyzer Tool -Test all cables to ensure no faults. Analyze how mobile signal propagates in the building.
  3. Samsung Galaxy phones (one for each operator), with the app, Network Cell Info Lite. These can be older model, lower cost phones. See the signal power, the frequency band, and the service. use phones to test call quality from each operator.
  4. iRepeater – use an iRepeater to record the outdoor signal strength, on the roof of the building. This information can be used in the FloorPlanner tool to help design the system more accurately.

What is the difference between a signal booster and a repeater?

While the terms “booster” and “repeater” are sometimes used interchangeably, there are important technical differences between the two.

A booster is a device that simply amplifies a signal it receives and re-transmits it. There is typically no filtering or interference control in the device. Such devices are usually sourced at low cost through on-line markets. Boosters do not meet the required European Standards and as such cannot carry the CE mark (Even though many do so fraudulently)

A repeater also re-transmits signals it receives, however such devices include filtering and interference control which provide better coexistence with other spectrum users. Such devices meet the applicable standards and carry the CE mark.

Stelladoradus only manufactures  repeaters.

Is Tax removed if I am a business?

There are 2 cases with regards to VAT and business.

1) If you are a business (hold a valid EU business VAT number), and reside in the same country as your chosen reseller, VAT will be added. However, you can write this VAT off your accounts at the end of year.

2) If you are a business (hold a valid EU business VAT number), and you reside in another EU country to that of the reseller you are buying from. Tax will be removed automatically.

Example: You live in Belgium but are buying from a French reseller.

In this case, VAT will be deducted from your order.

 

Are all repeaters the same?

No. The two defining specs of a repeater is its frequency and power. Here at Stella Doradus we have designed and built the complete range of mobile repeaters. Every frequency and power option is available.

What frequency repeater do I need?

For homes, we recommend at least a dual band repeater, (LG, GD or GW). Choose from the Stellahome family.

For businesses, we recommend a 3 , 5 or 6 band repeater. Choose from the StellaOffice family or an i-Repeater.

Please contact us to find out exactly which repeater option is best for you.

Why do I lose mobile phone signal indoors?

The farther away from the base station, the weaker the signal. Furthermore, hills, trees, walls, metal foil insulation and triple glazed windows in your building all attenuate mobile signal to differing degrees.

Do mobile repeater kits, or boosters really work?

Repeater kits are the cheapest and most effective way to get mobile signal into your house/ office.

Here at Stella Doradus,  we manufacture our own repeaters. Guaranteed to boost mobile signal into your house and perform to the highest standard.

What makes StellaDoradus different from the competition?

We are the only manufacturer of mobile repeaters based here in Europe and we’ve been in business for more than 25 years. All the other repeaters on the market are shipped in from China or Taiwan, with no quality control and circuit protection for noise control.

All our repeaters all have sophisticated network protection technology that has proven itself to be very reliable over many years. This is recognised by regulators who allow us to sell in their countries.

 

 

 

 

How many devices can use the repeater at the same time.

There really is no limit to how many devices can use the repeater at the same time. The repeater just amplifies and re-transmits the outdoor signals is “hears”. So, from the point of view of your phone, it does not know it is communicating through a repeater. The base station to which your phone is communicating with makes all the intelligent decisions such as allowing your phone onto the network etc. So, the question

”How many people can use the repeater at the same time?” should really be

“How many people can use the base station at the same time”.

The answer is many hundreds.

How do I know, before I buy, that a mobile phone repeater will work for me?

In order for the repeater to work well, it must be able to receive a good signal. It can then amplify the signal and re-transmit it indoors. The best way to check if there is enough signal available is to use the signal strength indicator on your phone. Go outside and hold the phone in the location you would like to install the outdoor antenna(usually the roof). Check how many signal bars you have. You should really see a minimum of 3 bars to be certain the repeater will work well for you.

The outdoor antenna that comes with the repeater kit is a much more powerful antenna then the one in your phone. If, outside, you have at least 3 signal bars on your phone , then the outdoor antenna will receive an excellent signal. The repeater will amplify this and re-transmit a clean strong signal indoors.

If you can’t find a location where your phone sees 3-5 bars, but instead sees only 1 bar, the repeater will still work. However, in this case, you must use a more powerful external parabolic antenna and a lower loss cable(LMR400). We can customize this for you. Just email us.

If you can’t see even 1 bar, it is probably best not to buy a repeater.
