Lots of indoor and outdoor 5G routers are coming into the market with high bandwidths and configurability. The two most common 5G bands are mmWave band and sub-6GHz band. For the mmWave frequency band, the signal is weaker, range is reduced and penetration through walls and windows is poor. Therefore, for reliable communications in this band, high-power outdoor units are required that have 5G capability.
NEC Corporation announced the iPASOLINK IAP3 series High-Power Outdoor Units (ODU) and an Outdoor Branching (BR) Combiner (OBC2) for 5G networks. The new series of ODUs deliver up to 5dB of transmission power improvement in the higher modulations. This means that the device is capable of handling high capacity data links.
It supports 6 to 23 GHz bands and channel widths up to 112 MHz with adaptive modulation (AMR) support up to 4096 QAM. The adaptive modulation is important for high reliability. High -frequency mmWave frequency band is more prone towards atmospheric attenuation. These interferences decrease the modulation rate and therefore, adaptive modulation is necessary in such cases.
The IAP3 series includes Automatic transmitter power control (ATPC) for increased efficiency. Plus, it ensures that all standard radio configurations are supported, including Cross Polarization Interference Cancellation (XPIC) and Space Diversity operation.
The series, moreover, includes a N-on-1 hybrid coupler. Hybrid couplers are directional couplers used in communication systems to divert or converge power. The N-on-1 hybrid coupler in this case, increases capacity, availability and flexibility allowing operators to use either multiple channels in a single band or combine channels in different frequency bands. NEC offers N-on-1 hybrid coupler in a compact, lightweight package to reduce the tower loading.
NEC’s compact outdoor branching combiner OBC2 (essentially a radio channel combiner) allows configurations of up to 16 radio channels and features configurations supporting capacities up to 10 Gbps. It also provides support for operation at higher modulations up to 4096 QAM. In addition, it delivers superior RF performance, minimizing transmission power losses through reductions to insertion loss and signal distortion in the branching circuit.
