LAS VEGAS--Rival U.S. operators are concerned about the "peak wars" that Sprint might initiate using its vast spectrum holdings, said Mike Murphy, Nokia Networks' head of technology, North America.
Most mobile operators are planning or actually deploying indoor and outdoor small cells to densify their LTE networks, but the pending widespread deployment of small cells is creating an urgent and unprecedented IT security threat, according to Martin Nuss, CTO at Vitesse Semiconductor.
LAS VEGAS--Michael Peeters, wireless CTO at Alcatel-Lucent, is getting frustrated with the industry's approach to 5G, which he contends is getting everything but the kitchen sink dumped into it.
UK-based mobile operators rejected calls by the government to create a national roaming agreement in an effort to improve poor signal coverage in rural areas, although operators say they are working with the government by looking at various options to help address the problem of mobile black spots, or "not" spots.
Due to their portability and the availability of mobile core solutions that provide communications capabilities when there is no access to traditional infrastructure, small cells are increasingly being seen as a key enabler for bringing LTE to military and public-safety verticals, says SNS Research.
Cable operators have dallied in wireless numerous times over the years, but nothing has really stuck. Their Pivot and SpectrumCo initiatives came and went, and it seemed the MSOs might never carve out a significant role in wireless communications. But their wireless prospects changed for the better as soon as they started dabbling in unlicensed, rather than licensed, spectrum and nomadic, rather than highly mobile, services.
Genband is making an aggressive play in mobile via the introduction of its Simply Mobile framework that combines cloud, over-the-top (OTT) and HetNet functionality with a developer platform.
The Small Cell Forum's ongoing research agenda targets a host of possible deployment scenarios, including the use of movable small cells as well as dedicated and standalone small cell-based networks. Further, a "tremendously exciting" initiative within the forum aims to apply the concept of virtualization to small cells, said Alan Law, the group's newly elected chairman.
Its backers no longer call it LTE Unlicensed (LTE-U), though that is an apt description. Regardless, the technology now referred to as Licensed-Assisted Access (LAA) has won kudos for its performance in the 5 GHz band, with tests conducted by Huawei and NTT DoCoMo showing the approach delivers better performance in both coverage and capacity compared with current widely deployed Wi-Fi equipment based on the 802.11n standard.
One of the more interesting filings in the FCC's ongoing 3.5 GHz proceeding is a letter submitted by China Mobile, the world's largest wireless operator, which pushes the TD-LTE agenda.
