LTE Carrier Aggregation--Meeting the Challenges of the 'Need for Speed' and Capacity

By: Peter Bernstein, TMC Senior Editor

In business as well as our personal lives there are finite resources that gate our activities. The big one that covers both is time which we cannot create more of and hopefully optimize for obvious reasons.  In mobile communications the issue is getting the most out of not just the finite but scarce radio frequency (RF) spectrum allocated for service provider networks. 

Realities are that in most parts of the world mobile service providers have access to different frequency bands as a result of things like auctions and mergers. Thus, they have a need to mesh their various spectrum assets (i.e., bands and associated carriers) in general. They also must optimize them to meet the insatiable appetite of customers for bandwidth-hungry services such as real-time and streamed video where Quality of Experience (QoE). Indeed, QoE and its extensibility to cover anywhere a customer is located is now foundational for attracting and keeping customers.
