For most people, Nokia company is associated with the manufacturer of mobile phones, which missed the revolution initiated by smartphones with a touch screen and now returned to the market of Android devices. However, in fact, this Finnish company is one of the main players on the market of telecommunications equipment manufacturers and specializes in the construction of cellular networks. In addition to traditional solutions, Nokia also invests in MulteFire technology, which allows the construction of private LTE networks using the unlicensed 5 GHz band, which is also used by Wi-Fi networks.

Modern LTE-Advanced base stations offer a data download speed of 1 Gbps, and soon this value will increase to 1.2 Gbps. Unfortunately, operators can not take full advantage of the potential of currently available technology. There are already smartphones available on the market that can aggregate 5 bands and in ideal conditions get the desired data transmission speed. The problem is that this is possible only when 20 MHz channels are aggregated. However, there is not a single operator around the world that would have reservations for 20 MHz frequency blocks in each band. The second problem is also the fact that the currently used frequencies are heavily loaded. Mobile carriers can increase the network capacity by adding additional base stations, but this activity requires a lot of time and investments. Therefore, the operators are interested in adapting the unlicensed 5 GHz band for LTE networks.

Nokia announced the world’s first MulteFire module

The device will be available for sale in the second quarter of this year and is compliant with the MulteFire Alliance Release 1.0. The offered data transmission speed is 300 Mbps. The biggest advantage of the new solution is the simplicity of installing small base stations. MulteFire combines the simplicity of Wi-Fi with LTE performance. The demonstration prepared by Nokia employees shows that MulteFire not only offers a higher transmission speed than Wi-Fi networks, but also has a better coverage. At the same time, we are not dealing here with any tricks related to increasing the power of the transmitted signal. The Nokia device works with 1 W power, which is the maximum level allowed in the unlicensed 5 GHz band.

The MulteFire Association was founded by Nokia and Qualcomm. Currently, it includes such companies as: SoftBank, Cisco, Huawei, Ericsson, Intel, or American Tower. In August last year, Samsung joined this group as well.
