Scalable Enterprise Small Cell System

As the use of smartphones and tablets skyrockets, an unprecedented amount of mobile broadband capacity is required inside buildings. The macro-cellular network is not designed to provide either reliable coverage or massive capacity indoors. SpiderCloud can, with its breakthrough Enterprise Radio Access Network (E-RAN) system.

SpiderCloud’s E-RAN system can deliver up to 200 sectors of UMTS or LTE capacity inside buildings as large as 1.5 million sq. ft., with 5 bars of coverage. It consists of two elements:

  • Radio Nodes: High capacity enterprise small cells, capable of providing up to two sectors of UMTS and LTE capacity
  • Services Node: A small cell controller that makes it easy to deploy, integrate and manage a dense network of Radio Nodes

Radio Nodes are connected to the Service Node over a standard Ethernet Local Area Network (LAN). Mobile operators can build a dedicated Ethernet LAN for Radio Nodes, or share the existing enterprise LAN using Virtual LAN (VLAN) technology.

The Services Node configures and optimizes a dense network of Radio Nodes using Self-Organizing Network (SON) technology, integrates with the mobile operator’s core network using standards-based interfaces, manages all handovers inside the building as well as handovers with the macro-cellular network, and ensures that the E-RAN system meet KPIs operators expect.

E-RAN can be used in enterprises of all sizes, from retail stores and branch offices to corporate headquarters and university campuses. For buildings larger than 100,000 ft2, the Services Node is typically deployed on premises. Smaller buildings can share a Services Node located in an operator’s data center.

SpiderCloud’s self-organizing network (SON) technology and its use of existing Ethernet infrastructure for connectivity and power, ensures that its system can be installed in a large building within days, rather than weeks or months, that legacy in-building solutions require.

E-RAN is the first small cell system that meets key performance indicators (KPIs) that demanding operators such as Verizon and Vodafone expect in large, high-density buildings. SpiderCloud’s support for UMTS soft handovers and LTE fast handovers between radio nodes ensures seamless in-building mobility and extremely low call drop rates. Commercially deployed E-RAN systems deliver a call setup success rate (UMTS), and E-RAB establishment success rate above 99.5% while keeping call drop rates below 0.5%.

E-RAN systems deliver a massive amount of indoor capacity. A dual-carrier LTE system with just 24 radio nodes can offer more than 2.5 Gbps of throughput, enough to stream 500 HD video streams. An E-RAN system with 100 radio nodes can do four times as much. As a result, commercially deployed E-RAN systems are not limited by capacity of the airlink, but by the amount of backhaul provisioned. An operator can add capacity to a commercially deployed E-RAN system by provisioning more backhaul. No truck rolls needed to add channel cards in baseband units, or buy capacity licenses.

E-RAN is designed for integration with Enterprise intranets, and for creating new cellular-aware services. The Services Node is capable of locally switching data from authorized mobile devices to an enterprise’s LAN. The Services Node can be purchased with an integrated Mobile Edge Computing (MEC) platform which can be used to create new applications using a wealth of local intelligence available at the Services Node, ranging from presence to location and analytics.
