In order to increase the capacity of the electricity network at a low cost and to facilitate the transition to a low carbon economy, DA will offer significant savings, and will enable generation and demand to connect to the network faster. Utility DA upgrades are a necessity in supporting the proliferation of distributed renewables and electric vehicles. New capacitor banks, voltage regulators, load tap changers, as well as the retrofit of older units with monitoring and control modules to allow for feeder, substation, or system-wide coordination will be crucial for the next generation grid.
Like the Interstate Highway system in the 1950s, building out a national LTE infrastructure in the U.S. is a major undertaking. The largest challenges in building out an LTE network consider of planning, staging, and deploying the technology at maximum speed and with minimal costs. Mobile operators are in a tight race to build out LTE networks in the U.S. as quickly and cost-effectively as possible, and backhaul is a key component of the job.
A new iGR study shows that demand for microwave backhaul is forecast to grow at a Compound Annual Growth Rate (CAGR) of 68% from 2011 to 2016, but that the issues associated with the technology could significantly slow down deployment.
On Thursday, SK Telecom announced a deal with Ericsson to extend its LTE network. According to SK Telecom, demand for LTE services in South Korea has increased rapidly since the commercial launch of the technology in the country in July 2011. As of today, SK Telecom provides 2.4 million of its 26 million subscribers with LTE technology.
India's Telecom Commission is seeking clarity from the sector regulator on some of its 2G airwaves auction proposals including the base price, which mobile carriers want to be cut by 80%.
R. Chandrashekhar, the top bureaucrat in the country's telecoms ministry, said the Telecom Commission did not have a view yet if the proposed near 10-fold rise in auction starting price from what carriers had paid in a 2008 sale was "too high."
Accuris Networks, a provider of mobile technology interworking, and Acme Packet, a provider of session delivery network services, on Monday announced a partnership to launch a Wi-Fi Mobile Interworking service, which gives mobile operators a way to extend network coverage and network capacity to Wi-Fi, provide carrier-grade security and offer value-added services even when users offload to Wi-Fi networks.
The top three U.S. telecom carriers, Verizon Communications, AT&T Inc and Sprint Nextel Inc, recently released financial results for the first quarter of 2012. All three carriers reported higher-than-expected financial results for 1Q2012.
In the past, satellite was dismissed as a wireless backhaul technology, mainly for cost reasons; but as pricing for wireless data increases and carriers shift away from unlimited plans, there is now a compelling, and profitable argument for Ka Band’s use in LTE network backhaul. Ka Band plays well with LTE’s all-packet architecture.
The first places to receive LTE coverage in Germany were not large cities like Berlin or Munich, but towns of 5,000 inhabitants or less. Now that rural areas have been covered, German providers will now start to update urban areas with LTE coverage this year.
On Tuesday, AT&T Inc reported a higher-than-expected quarterly profit as iPhone sales declined, reducing the amount of cash it had to pay Apple Inc and boosting its margins.
