The 3rd Generation Partnership Project (3GPP) defined a SON specification to allow base stations to discover each other when inserted into a network and to adjust their radio frequency (RF) signal strength to avoid overlap and interference.
[5][6] AirHop was founded to extend this technology beyond initial network start-up to also provide ongoing interference management and spectrum reuse.
[3] This gives carriers the ability to both initialize the network and ongoing RAN intelligence to adjust signal levels as small cells come online and overlap with each other.
[1][4][11] AirHop showcased the first of its 3GPP Long Term Evolution (LTE) solutions by running an HD video transmission demonstration on Texas Instruments’ TCI1648x DSP at CTIA – The Wireless Association in March 2009.
[7] AirHop and Argela demonstrated eSON on a commercial 3G femtocell at Mobile World Congress in February 2011[16] and its first 4G/LTE customer was announced in May with the introduction of Wazco's Metrostorm metrocell.
