Wireless Blog posts referring to the Mobile World Congress (MWC).
With all the focus on LTE, LTE-Advanced and now 5G, it is easy to forget that High Speed Packet Access (HSPA/HSPA+), based on 3G WCDMA, is still the dominant mobile broadband technology worldwide. In February 2014, the Global mobile Suppliers Association (GSA) reported that all WCDMA operators had launched HSPA, with 547 networks providing access to… Read more
One of the major features of LTE-Advanced is Carrier Aggregation, which allows mobile network operators to combine a number of separate LTE carriers. This enables them to increase the peak user data rates and overall capacity of their networks and to exploit fragmented spectrum allocations. I introduced the fundamentals of Carrier Aggregation in a previous… Read more
In the first few months of 2013 there have been signs that LTE Carrier Aggregation (CA) is coming to fruition, with a series of announcements of demonstrations, trials and launch plans by network operators and equipment manufacturers. Here are some examples: Ericsson, Qualcomm Technologies and Sierra Wireless provided the first public demonstration of LTE Carrier Aggregation at Mobile… Read more
The ability of HSPA, HSPA+ and LTE to deliver high spectrum efficiency is dependent upon them being able to reach the instantaneous peak data rates from each technology. To achieve high overall average throughputs from a base station, the base station must be able to achieve the maximum data rate possible in excellent radio conditions.… Read more
