I am excited to know that 3GPP has started to roll out the plans for freezing the content for Release-12 by end of 2014, even before the Telecom giants completed their implementation of Release 9 and 10.
Takehiro Nakamura, RAN Chairman has conducted a two day workshop which saw many participants who were the members of major telecom service providers from across the Globe, which focused on prioritizing the below areas.
1. Energy saving
2. Cost efficiency
3. Support for diverse application and traffic types
4. Backhaul enhancements
The first 3 terms are self explanatory and my interest here is to help you understand the Backhaul Enhancements.
Backhaul is the use of wireless communications systems to get data to/from an end user from/to a node. This also refer to the transmission of network data over an alternative route when the normal route is unavailable or congested. Example: The most common method of wireless backhaul involves microwave systems although satellites can also be used.
Here i think the challenge would be in choosing an appropriate backhaul solution that would fit the techno-economically. Lets wait to hear those details sooner.
