In the quest for substantial increases to the capacity and throughput of mobile networks, unlicensed radio spectrum is expected to have an important role in 5G systems from 2020. However, work is already underway in 3GPP to allow 4G LTE-Advanced networks to take advantage of unlicensed spectrum much sooner. The Licensed Assisted Access (LAA) feature will… Read more
Following a low-profile launch by Three in December 2013, all four of the UK mobile network operators now offer 4G LTE services to at least some of their subscribers. While early impressions of LTE data services are favourable, I have heard mixed reviews about the quality of voice calls for LTE subscribers in the UK,… 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
At this month’s International Consumer Electronics Show (CES 2013) in Las Vegas, Verizon Wireless announced plans to launch a video broadcast service based on eMBMS, the LTE variant of the 3GPP Multimedia Broadcast Multicast Service (MBMS). Amid reports that a number of network operators are considering eMBMS, Verizon took the opportunity of CES to demonstrate… Read more
In his wireless blog, Mark Heath of Unwired Insight discusses the latest LTE speeds reported by mobile network operators. Am I the only one that gets frustrated by all the hype surrounding LTE speeds and LTE performance? Many in the industry are seeing LTE as the means of avoiding the looming 3G capacity crisis, as… Read more
While some industry observers pointed to the underutilisation of 3G networks following their launch as a sign that 3G networks were not needed, there have been many developments that have kick-started the take-up and usage of 3G services, which include the: launch of mobile broadband services (using USB modems and datacards), at affordable prices launch… Read more
HSPA+ (also known as HSPA Evolution) adopts an even higher-order modulation than HSPA (64QAM compared with 16QAM) to boost peak rates further. Performance is further enhanced through the adoption of Multiple Input Multiple Output (MIMO) antenna technology. With MIMO, more than one transmit antenna is used at the base station and more than one receive… Read more
