Massive beamforming in 5G radio access

Antenna beamforming hero

How can you get all users in high rise buildings >200 Mbps throughput wherever they are, and reduce network energy consumption at the same time? Through advanced antennas, flexible, user-specific beamforming and a new mobility algorithm.

The key is to use spectrum at high carrier frequencies, and to deploy advanced antennas to combat the challenging propagation conditions at these frequencies. We’d like to share with you the facts of our solution, which we demonstrated at the Mobile World Congress recently.

Evolved Capillary Networks

Capillary hero

Short-range radio technologies can be used to connect groups of small devices to the Internet, via capillary gateways and cellular networks. But then, how do we manage the devices in these large scale sensor networks? And what’s the best way to process the data generated by these networks, so we can make use of it for real world actuation?
At the recent Mobile World Congress, we used a model railway with embedded sensors to demonstrate how we address two important aspects of IoT and sensor networks. Continue reading

Licensed Assisted Access: Practical Coexistence Solutions

Channel scanning and selection to operate a wireless network in frequencies with low received interference is always the first and most effective step for spectrum sharing and interference mitigation. Smart channel selection is thus sufficient in most scenarios (e.g., isolated and sparse deployments). In this second blog post on LAA, we discuss co-channel operation measures when different systems need to operate on the same frequencies. Continue reading
