​From cell centric to user centric with beamforming

Massive MIMO with beam forming improves the end user experience by significantly increasing network capacity and coverage while also reducing interference. This is done by increasing the effectiveness of the transmission.  Sending out radio waves as highly focused beams delivers a stronger radio signal, with a higher data throughput for greater distances. This is also an ideal solution to increase capacity in congested areas -- especially when adding another frequency band isn’t really an option. The Massive MIMO antenna array with a large number of steerable ports enables beam forming,  which means that radio signals and information are sent directly to the device instead of broadcasting across the entire cell.  This has the added benefit of also reducing radio interference across the cell, resulting in a more enjoyable user experience.

Traditional Site

• Traditional sites project radio waves in a fixed predefined pattern – similar to a flood light

Massive MIMO Site

• Massive MIMO sites project radio in narrow beams directed to the users – similar to a spot light
• Multiple beams can be created which will dynamically adjust to user locations & usage
• The end result is an increase in signal and a reduction in interference from other users in the sector – improved throughput to each user in the sector
