U.S. Carrier Ethernet Revenue Growing 37%

The U.S. retail carrier Ethernet services market has currently entered the growth phase of the product lifecycle, recording an impressive growth rate of 37 percent, according to researchers at Frost & Sullivan.
Market revenues for 2009 exceeded $1.5 billion. Ethernet as a transport service is gaining traction for a number of reasons, including scalability and value, both for long-haul and access applications, Frost & Sullivan says.
But Ethernet still is not widely available in the U.S. markets and service providers are struggling with significant price compression in the long-haul markets. Customers still have some concerns about service level agreeements for Ethernet virtual private line (EVPL) services.
As the market migrates from traditional private lines to Ethernet, customers expect the same kind of service performance as available on T1/T3 and SONET circuits. For this reason, Ethernet private line, which is enabled over SONET, is more popular than EVPL.
Service providers are increasingly focusing on offering SONET type of protection on switched Ethernet services. However, the concerns are largely attributed to the customers comfort level with moving to a shared platform as compared to dedicated circuits.
Going forward, 10 Mbps and 100 Mbps ports will constitute a major portion of the long-haul E-LAN ports sold.
Customers are opting for higher port speeds for head office to data center connectivity and lower speeds to connect the branch offices.
“Combining layer-two Ethernet-based VPN with layer-three MPLS VPN is a key trend in the market,” Frost & Sullivan says.

4G Adoption Might Take a While

4G Adoption Might Take a While
If an analysis conducted by NERA Economic Consulting of 3G adoption has any relevance for 4G, it might well take longer than most now believe for 4G services to be adopted.  The reason is the industry’s experience with 3G. The networks will be built; that isn’t the problem. The issue is that consumer adoption might be slower than most seem to forecast.
Vice President Christian Dippon notes that only two countries–Japan and South Korea–currently have more 3G than 2G subscribers. Furthermore, leading nations such as the United States, the United Kingdom and Germany have 3G penetration rates of less than 30 percent, about seven to 10 years after the services first were made available.
Dippon speculates that mobile subscribers do not view 3G services as being sufficiently different from 2G services. Right now, that might be the case for many potential 4G customers as well.
Faster is better, no doubt. But users are going to weigh the additional speed boost with the additional cost. And many likely will conclude that 3G is good enough.
See more at http://www.nera.com/67_6802.htm.
The average 3G penetration rate in the European Union 15 countries for year-end 2009 was 25.7 percent, far short of the predicted 60 plus percentage range or the stated 30 to 80 percent rates some experts originally had foreseen.
Similarly, contrary to the forecasts, the leading countries were Spain with a 43 percent 3G penetration rate followed by Sweden with a 40 percent penetration rate. The United Kingdom and Italy had 3G penetration rates of 32 and 30 percent, respectively, which was less than half of the predicted rate, Dippon says.
The apparent slow diffusion of 3G technology is not limited to the EU 15 nations. Rather, it seems to be a worldwide phenomenon. The December 2009 U.S. 3G penetration rate was 26.1 percent, which is less than one-third of the number forecasted for the U.S. by various analysts for 2010.
4G is not going to sell itself, and so far the only message users seem to be getting is that 4G is faster. That it is. But whether the user experience is commensurately better, given the higher cost, is not yet clear.
That doesn’t mean 4G networks will come on line any slower. But revenue remains the issue.

LTE Has Backhaul Implications

CenturyTel, Cox Communications, Verizon Wireless, Rogers Wireless and MetroPCS are the North American firms introducing fourth-generation wireless service in 2010, and each of those carriers will have to provision backhaul bandwidth ranging from 50 Mbps to 200 Mbps from each tower site, a shift to all-Internet Protocol traffic and will in some cases require denser transmission networks,  says Erik Boch, registered professional engineer.
Those issues have clear implications. It will not be practical to keep using T1 lines as the backhaul method, in part because so much more bandwidth is required, in part because of the type of traffic and in part because there simply will be many more transmitting sites, at least for licensees operating in Gigahertz frequencies rather than sub-Gigahertz bands.
Verizon Wireless will have an advantage: it is using 700-MHz frequencies that will propagate so well that a denser network than what the carrier has built for 3G services will not be required.
But some Long Term Evolution networks In order to combat the reduction in coverage performance, the cells have to be moved closer together into a “micro-cellular” networking structure. Additionally, particularly in the downtown urban-canyon environment, the base stations have to be moved off the roof-tops and brought down toward the street level in order to achieve useable coverage at this level.
