Last week ExteNet Systems announced that it has deployed a Part 96-ready fixed wireless LTE-based network for Peak Internet, which provides broadband internet services to residential, small business, enterprise and government customers in Colorado Springs and Pike’s Peak.
ExteNet deployed a software-based distributed evolved packet core (EPC) with Nokia’s Citizens Broadband Radio Service (CBRS)-ready LTE radios on the premises of Peak Internet to enable the service over the licensed 3.65 GHz band with a future, software-only upgrade path to the 3.5 GHz CBRS band. The deployment includes a will support future mobile roaming services for Tier 1 providers.
It is not ExteNet’s first foray into fixed wireless. Last September, it announced a similar deployment with a Cal.net, which provides broadband Internet services to rural communities in the Sierra Nevada foothills ranging from the northeast to the southeast of Sacramento.
In the past WISPs had to depend on WiMAX, Wi-Fi and some other proprietary wireless technologies, operating in the Part 90 spectrum. But things are changing for these mostly small, rural operators as LTE becomes more pervasive and affordable.
Five or six years ago, ExteNet, which is known for distributed antenna systems and distributed network systems, began mapping out what would be the next area of growth beyond the booms in wireless coverage and capacity. The next phase would be functionality, they decided.
“We needed typical core functionality to be distributed closer to the edge of the network,” said Tormod Larsen, ExteNet chief technology officer. “It couldn’t be based on expensive proprietary hardware, so we found a partner to develop a flexible software-based solution that resides on standard hardware platforms. We went to the rural markets with this scalable, software-driven effective packet core to enable WISPs and other operators to develop their LTE networks.” Additionally, a radio access network (RAN) vendor neutral approach was chosen, allowing the customer to choose its preferred RAN vendor.
ExteNet is making LTE more affordable by offering it on an infrastructure-as-a-service basis, distributing intelligence and control to the internet at the edge of the network and not in a carrier’s centralized core. ExteNet typically partners with the operator and offers them an economical avenue to purchase the EPC and the RAN equipment as an infrastructure as a service (IaaS) solution.
“The management platforms for Ericsson and Nokia can be expensive,” Larsen said. “ExteNet invests in the technology and requires long-term agreements from its customers. We spread the cost over multiple customers.”
ExteNet Systems Partners with Illinois Valley Cellular to Enable 4G LTE Connectivity
ExteNet’s game plan goes well beyond wireless internet service providers to bring enhanced broadband wireless connectivity to rural cellular carriers and building owners. Last October, the ExteNet announced a partnership with Illinois Valley Cellular (IVC) to enable 4G LTE broadband connectivity for north central Illinois.
ExteNet’s localized packet core served as a replacement to IVC’s hosted core approach, which greatly reduced backhaul costs and reduced latency by up to 75 percent. Additionally, it will eventually support mobile roaming services for Tier 1 providers while being 5G ready.
“Our combined EPC with our small cell and distributed network technology will help rural carriers compete with the tier-one carriers from a cost perspective,” Larsen said.
In the future, Larsen thinks the IaaS business model the virtual EPC will allow ExteNet to market CBRS private LTE systems to building owners in-building wireless systems or municipalities for IoT applications.
