Orthogonal frequency division multiplexing (OFDM) solutions based on existing mobile access technologies (3GPP Long Term Evolution (LTE) and LTE advanced) cannot solve alone the interference problem due to their high adjacent channel power ratio (ACPR) [1, 2].
The results of these studies provide a ground truth basis for developing future Cloud services with QoE requirements, as well as for dimensioning the underlying network provisioning infrastructures, particularly with regard to mobile access technologies.
According to the User Manual submitted to the FCC, the Shadow II also supports Unlicensed Mobile Access (UMA) technology, allowing T-Mobile @Home users to switch seamlessly between T-Mobile's cellular network and their home WiFi.
Long term evolution advanced (LTE-A) has emerged as a promising mobile broadband access technology aiming to cope with the increasing traffic demand in wireless networks.
The companys technology is slow but clearly developing a reliable mobile Internet access technology is one of the biggest, and most important, hurdles facing the players in the broadband industry.
The next version of the WiMax standard, which has yet to be finalised, will support mobile access, provided the technology can be made small and energy-efficient enough to fit into laptops and handheld devices.
Advances in wireless networking, mobile broadband Internet access technology as well as the rapid development of ubiquitous computing means e-learning is no longer limited to certain settings.
Therefore, the mobility of the mobile network may result in access technology changes (vertical handovers).
Compared to the different wired access network technologies, mobile access networks are significantly less energy efficient [1].
One of the great things about the Cloud is that, for the price of an office lunch, a small business can have access to collaboration, mobile access and backup up technologies that previously only large corporations with IT departments could manage and afford.
