Cambridge Broadband Networks’ Lance Hiley tells Keith Dyer in this video that point-to-multipoint backhaul is ideally suited to LTE architectures and traffic demands, and can solve backhaul challenges assoicated with the dense deployment of cells in urban environments.
Latency Advantages for 40/100GB Networks
June 8th, 2011
Mid-2010 saw the introduction of the new 40/100GB networking standard, an obvious capacity increase, but the lower latency also is a key advantage, much as Long Term Evolution has better latency performance than third generation mobile air interfaces.
Compared to gigabit or 10 Gbps networks, network latency is less than two milliseconds, even over long network hops of 100 miles or more, says Craig Denton, CEO of Next Connex.
In turn, these speeds mean that latency in the network connection between head offices and data centers can be minimized compared with other factors in application or data processing.
High network speeds also better accommodate the frequent, temporary bursts generated by data intensive applications. If the data rate of these bursts exceeds the capacity of a network link, data will be forced to queue, introducing unwanted delays and even risking crashes, Denton argues.
LTE Activations Surprise Some Observers
June 6th, 2011
In the first quarter of 2011, Verizon Wireless activated half a million Long Term Evolution-enabled devices, while Japan’s NTT DoCoMo scored 25,000 LTE subscriptions, according to ABI Research.
“We believe LTE adoption will take off more rapidly than expected, with more operators announcing network launches and existing players widening network coverage,” says ABI Research analyst Fei Feng Seet. Though North America is expected to be the hot spot for LTE activations, in most other markets faster versions of 3G are expected to drive growth.
In Asia, 3G networks are starting to gain momentum. With Indian spectrum auctions concluded last year, ABI Research puts the number of 3G subscribers in that country at more than 100 million, including both WCDMA and CDMA2000; while China’s overall 3G subscriptions approach 62 million.
However, many Asian operators are still working on expanding their 3G footprints, as consumers demand nationwide coverage. Total 3G subscriptions in Asia are set to cross 1.2 billion by 2016.
