![]() However for the public you cannot install and operate a repeater unless it is a Cel-Fi unit purchased through an authorized reseler like ourselves, or a Cellutronics fixed install repeater on 2Degrees. For some of their large corporate customers they will design and have repeaters installed for them professionally. In NZ the owners of the cellular spectrum (2Degrees, Spark, and Vodafone) are the only people who can give approval and therefore license for a repeater. We talk about this in other sections, but the two units are the Cel-Fi unit, and the Cellutronics fixed active repeater system for 2Degrees (does UMTS and GSM). There are in fact two, and we are the only company that can sell two repeater types. ![]() It is not true that the Cel-Fi unit is the only legal repeater in NZ. While we are talking about false advertising. So please be weary of other companies that either don't know what they are talking about or have false advertising. The 2.4W is actually in reference to GSM which Spark don't use. The Bury kit does not offer any increase in power compared to any other Spark smartphone. This is false advertising and is incorrect. Furthermore, whilst we are talking about car booster kits, there is a company in NZ claiming to sell a Bury CPE1100 2.4W car kit on Spark. Despite some companies in NZ claiming car boosters to be legal, they are in fact illegal and cause many problems for Spark, Vodafone and 2Degrees. By the way this includes any active amplifiers that are used in booster car kits. + Are repeaters legal or illegal in NZ?Ĭellular repeaters (so active powered repeaters for cell phones/mobile phones) have to be licensed. Our products, as well as the information and data on this website, is our original work. All our products are guaranteed and developed by leading New Zealand RF engineers. One last thing, beware of the companies out there who make a living from copying our products, without ensuring their products have the same level of integrity as ours. If you are not sure, give us a call and we are more than happy to talk to you. So that should help you understand what a repeater is. And it does cause Spark, Vodafone and 2Degress a lot of hassle. Well unfortunately, they are wrong, this is an active amplifier (takes power) and is illegal. We often get people ringing us saying they don't have a repeater but have this cradle they have bought from one of our competitors that takes power and amplifies the signal (but the supplier assures us it is not a repeater). Okay so where were we? Right, so if you are not sure whether you are buying a repeater, check to see if it takes power (wires from it to a power source), and if it does it will have amplifiers in it. You won't hear it as we can't hear radio waves but your phone sure will, and so will all your neighbours' phones - Hence why you can be prosecuted! And guess what, your phone and your neighbours' phones won't work until the repeater stops oscillating (turned off or gain turned down). In other words, if the repeater hears itself (input to output), it will oscillate and squeal too. Sound familiar? This is what can happen with a repeater as well. Have you ever been at a school play or school band, community hall, or even a big concert and you have heard a loud squeal coming through the speakers? Everyone in the audience cringes until someone pulls the microphone away from the speakers or a techo turns the gain down on the microphone. There is another good analogy with a stereo amplifier you need to know about. If the repeater has too high of an input signal or too much gain (volume turned up), it will distort the radio waves to your phone (and other phones in the area!) with common symptoms including, but not limited to, missing words, dropped calls, low data speeds etc. This is the same logic for phones as well. As humans, our ears don't like distortion. Which is genuinely fine until you turn it up to the point where you hear distortion. ![]() A good analogy is with a stereo amplifier.Īs you know, as you increase the volume of your stereo the louder the sound gets. When this is done (amplification), distortion is introduced. If a box has power connected to it then it is likely it means it has transistors/Fets (amplifying devices) inside that take power (AC/DC) and convert this power to amplify radio waves. ![]() Genuinely speaking a repeater is a 'box' that has power connected to it. ![]()
