Pre-4G wireless standards
According to a Visant Strategies study there will be multiple competitors in this space:[15]
* WiMAX - 7.5 million units by 2010 (May include fixed and mobile)
* Flash-OFDM - 13 million subscribers in 2010 (only Mobile)
* 3GPP Long Term Evolution of UMTS in 3GPP - valued at US$2 billion in 2010 (~30% of the world population)
* UMB in 3GPP2
* IEEE 802.20
Fixed WiMax and Mobile WiMax are different systems, as of July 2007, all the deployed WiMax is "Fixed Wireless" and is thus not yet 4G (IMT-advanced) although it can be seen as one of the 4G standards being considered.
