A new white paper, Beyond LTE: Enabling the Mobile Broadband Explosion, and its accompanying slide presentation (pdf), was created in collaboration with Rysavy Research and member companies at 4g Americas.
It’s a handy summary of mobile broadband networks, past, present and future. Mobile broadband is becoming one of the most successful and fastest-growing industries of all time.
According to Rysavy, computing itself is transitioning from a PC era to a mobile era. Many users will never interact with a PC.
The wireless industry is addressing exploding data demand through a combination of technologies.
Newer releases of LTE will feature more efficient technology, denser deployments, small cells, HetNets, self-configuration, self-optimization, use of unlicensed spectrum with Wi-Fi, and the LTE operation in unlicensed bands.
Initial LTE deployments have been faster than any wireless technology previously deployed.
LTE Release 12, with completion expected by the end of 2014, will feature improved small cells/HetNets, LTE multi-antenna/site technologies (including Active Antenna Systems), Dual Connectivity, enhancements for interworking with Wi-Fi, support for emergency and public safety, device-to-device communication (also referred to as proximity services), addition of Web Real Time Communication (WebRTC) and more flexible carrier aggregation.
Mobile broadband has become the leading edge in innovation and development for computing, networking, and application development.
The explosive success of mobile broadband mandates ongoing capacity increases. The industry has responded by using more efficient technologies, deploying more cell sites, off-loading onto Wi-Fi, and working with government on spectrum-sharing.
In the U.S., a number of initiatives could improve industry prospects—AWS-3, television incentive auctions for 600 MHz spectrum, the 3.5 GHz small-cell band, more unlicensed spectrum at 5GHz.
Rysavy concludes that obtaining more spectrum remains a critical priority and that LTE/LTE-Advanced will be the most widely chosen technology platform for the remainder of this decade.
