The traditional approach of using filters to enable co-located radios to operate is inefficient as it is wasteful of spectrum due to large guard-band spacing required as well as inflexible thus limiting the use of LPDI waveforms. Based on research done at Stanford University, Kumu Networks' has pioneered the use of wireless self-interference cancellation techniques to create zero-guard band, software programmable filters that eliminate the need for fixed filters. The technology has been commercially deployed in US Tier1 LTE Mobile Operator networks. Recent technology advances has allowed Kumu to miniaturize the technology down an integrated circuit (RF chip) form factor making it possible for adoption in mobile, portable and airborne environments in addition to ground based, fixed infrastructure equipment.
