The first mile, which is also known as the local loop, the subscriber access network or the last mile, is the main link between the public network and an end user. DSL and cable modems operate at only 5 to 10% capacity of a typical LAN setup, resulting in bottlenecks in network application. Such bottlenecks occur even on the more expensive E1/T1 lines with speeds of up to 1.5 Mbps.
This problem can be resolved with the use of EFM or Ethernet in the First Mile solutions that allows businesses to move to an all IP network infrastructure using more affordable means. The following gives a brief overview of what Ethernet in the First Mile is and how it can be beneficial for your business.
What is Ethernet in the First Mile?
Ethernet in the First Mile is the nickname for the latest amendment to the Ethernet standard, technically called IEE 802.3ah-2004 that can deliver up to 10 Mbps high-speed internet connection for your business. This service provides more affordable high-bandwidth connections similar in capacity with more expensive leased lines, except that it makes use of bundled copper wires instead of costly fiber optics.
EFM is not a replacement of existing Ethernet networks, but it allows Ethernet protocols to run over single pairs of telephone wire or single-mode fiber strands – media types that are previously unsupported. If any of the bundled copper pairs breaks down, the EFM service will not fail completely but will readjust to a lower speed.
Who Should Use EFM?
EFM is well-suited for subscriber access networks, wherein subscribers are connected directly to the service provider. These include businesses that have existing leased lines or enterprises planning to deploy high capacity business internet access or virtual private networks. EFMs will occupy space in a similar manner as leased lines, allowing for additional services such as VoIP, video-on-demand, and TV-over-IP.
The Benefits of EFM
EFM offers cost-effective solutions for businesses, giving them high-bandwidth data transfer capacity without the need for installing expensive end-to-end leased fiber optic lines. In summary, EFM provides the following benefits:
• High Speed Internet/VPN connectivity for businesses
• Lower costs compared to traditional leased lines (up to 65% savings)
• Use of multiple copper pair bundles provides better resilience and higher levels of reliability
• Provides more cost-effective solutions for VoIP, VPN and Video with higher upstream and downstream connection speeds
What to look for in EFM Services
In the United Kingdom, 60% of businesses are already located in an EFM-enabled area. When looking a particular EFM service, choose providers that can offer speeds of up to 40 Mbits per second or higher, as theoretically EFM speeds can reach up to 100 Mbits per second.
Aside from that, look for services that guarantee symmetrical Internet access as well as VPN connectivity. EFM services also offer high 99.9% availability and resolves usual connectivity issues such as jitter, latency and packet losses.
Market Outlook for EFM Services
Ethernet in the First Mile is now made available to over 80% of businesses in the United Kingdom. The lower cost offerings make these services affordable to businesses who have previously never considered dedicated lines for their networks. These services will have increase coverage towards the end of 2011, providing more businesses better opportunities for business Internet access and virtual private network capabilities.
