I have chosen this model because it is compatible with any provider and it is really universal. This all-in-one quad-band unit perfectly improves voice calls and both types of mobile Internet – 3G and LTE as it works at four main frequencies - 900MHz and 1800MHz for GSM, 2100MHz for 3G Internet, and 2600MHz for LTE connection. It goes without saying that people using different mobile operators visit my supermarket and surely they all want to enjoy a good quality of mobile communication. It is a miracle that due to Nikrans NS-2000EDWL every customer is delighted with the level of cell phone signal in the supermarket. The indoor coverage of the amplifier is about 2000 m2, which is more than enough for my place. The device itself is very lightweight and compact with high isolation and low energy consumption.
I got the full kit with all the necessary accessories, so there was no need to buy anything extra. I just unpacked it and installed. The installation process, by the way, was very simple and understandable as it was described in the attached detailed manual. Now I am sure that my customers will have no dropped calls and disconnections while shopping, the audibility will always be good as well as the internet connection and its speed. If you are searching for an all-in-one amplifier, I can tell you that Nikrans NS-2000EDWL is the best solution.
