Local Area Network (LAN) utilizes Power over Ethernet plus “PoE+” from the Ethernet switch to power the Radio Nodes. Mobile operators can build a dedicated Ethernet LAN for Radio Nodes, or share the existing enterprise LAN using Virtual LAN (VLAN) technology.
By usage of standard enterprise Ethernet and a Radio Node installation process that is similar to enterprise Wi-Fi, the very large pool of Wi-Fi trained installation companies can now install cellular technology. The cost of physical installation is significantly reduced as compared to telecommunications technologies that require specialized labor and expensive coax cables. The optimal installations share the existing enterprise transport infrastructure to enable faster installation and reduce capital construction costs for materials.
In the building’s main Telecom closet, the E-RAN’s services node installs in a standard 19” equipment rack and only requires one Rack Unit (1.75”) of vertical space. The services node uses two 110VAC outlets for its redundant power supplies and only generate 512 BTU’s of heat per hour. All the headend power and space demands of earlier generations of indoor cellular equipment are removed with E-RAN.
Backhaul is also eased by E-RAN as it only needs a quality IP path to the mobile core. This can be in the form of Internet (provided the last mile has enough headroom for mobile traffic), MPLS, Metro Ethernet, or other private IP. Tough customer situations can use internet as a permanent solution or as a bridge solution to satisfy needs until a private IP connection is delivered.
