Edholm's law
The name "Edholm's law" was coined by his colleague, John H. Yoakum, who presented it at a 2004 Internet telephony press conference.[1] Slower communications channels like cellphones and radio modems were predicted to eclipse the capacity of early Ethernet, due to developments in the standards known as UMTS and MIMO, which boosted bandwidth by maximizing antenna usage.[2] In 2009, Renuka P. Jindal observed the bandwidths of online communication networks rising from bits per second to terabits per second, doubling every 18 months, as predicted by Edholm's law.The wide adoption of RF CMOS (radio frequency CMOS), power MOSFET and LDMOS (lateral diffused MOS) devices led to the development and proliferation of digital wireless networks by the 1990s, with further advances in MOSFET technology leading to rapidly increasing bandwidth since the 2000s.[12] In recent years, another enabling factor in the growth of wireless communication networks has been interference alignment, which was discovered by Syed Ali Jafar at the University of California, Irvine.
