Nomadix Service Engine (NSE)

The NSE software consists of an extensive patent and patent-pending portfolio of intellectual property covering more than 15 unique areas of functionality needed to successfully deploy public access networks.

By placing an NSE-enabled device in the HotSpot or HotZone, the provider can deploy a cost effective service - from a CAPEX / OPEX perspective while keeping the edge of the network secure and maximizing multiple revenue streams through a variety billing, wholesale and roaming capabilities.

The NSE provides the following key benefits:

For Service Providers:
Deploy a unified service offering across any size and type of HotSpot or HotZone
Maximize multiple revenue streams from service creation, applications, roaming or by wholesaling WiFi service to other providers
Get maximum flexibility out of your deployments by supporting the widest range of authentication, billing and roaming options
For HotSpot Owners:
Take advantage of a variety of deployment options from basic self installation to purchasing wholesale WiFi service from a retail provider
Enhance your customer retention by offering Internet access at your venue
Augment your branding and venue-specific services or offer access to localized content
Accept the widest variety of roaming users at the location with limited infrastructure investment
For End Users:
Get access to the internet from a fast growing network of HotSpot locations
Get a problem-free connection to the service with Zero Configuration changes
Gain access to local content and applications as part of an advanced service offering
Pay for services using a variety of mechanisms including credit card, scratch card or by signing up for a subscription-based service

  The NSE addresses the key issues of customer acquisition, provisioning, security and revenue generation faced by providers and venue owners when deploying WiFi public access. The NSE also knocks down the barriers encountered by end users accessing these networks by providing a secure, hassle-free, Zero Configuration experience when using the service.

Nomadix offers a full range of Access Gateways running the NSE software. All of our Access Gateways come with the NSE Core software package. Optional NSE Modules and User Count upgrades are also available.

Competitive Advantage

Most competitive offerings on the market today are either server-based or rely on a hard drive to provide their functionality. A major competitive advantage for Nomadix lies in the fact that we developed our software solution within a real-time operating system — VxWorks making it an efficient and reliable packet processor. Also, our Access Gateways are dedicated network appliances that provide superior scalability and reliability over competitive solutions that are server based or run on Operating Systems susceptible to virus attacks. Our patented systems provide unparalleled means to monetize public access and our solutions have proven high reliability and low failure rates. Reliability can be increased even more with our fail-over capabilities.

Providing a seamless experience for the end user while enabling the backend billing and authentication models needed by the provider, the NSE delivers key functionality in the following areas:

Customer Acquisition

Nomadix’ patented Dynamic Address TranslationTM (DAT) technology provides transparent broadband network connectivity as users travel between different locations—without requiring any changes to their computer’s settings or special client-side software—ensuring that everyone gets easy access to the network. A Nomadix-enabled network allows providers to acquire new customers in a cost effective method.

Service Provisioning

Once connected to the public access network, the NSE’s patented Home Page Redirection feature intercepts the user’s browser settings and directs them to a web site to securely sign up for service or log in if they have a pre-existing account. Nomadix offers redirection opportunities both pre and post authentication as well as at session termination for maximum branding flexibility for both the provider and the HotSpot owner.

Multimode Authentication and Access Control

In addition to supporting the secure browser-based Universal Access Method, the NSE simultaneously supports Port-based Authentication using IEEE 802.1x and proprietary authentication mechanisms used by Smart Clients from companies such as Boingo Wireless and iPass. Nomadix products enable multiple authentication models providing maximum flexibility to the end user and to the provider by supporting any type of client entering their network and any type of business relationship on the back end. Nomadix’ products can block access to the Internet or allow access to a pre determined “Walled Garden” area of the web until the user has been authenticated.

Billing Plan Enablement

The NSE supports a wide variety of billing models enabling the deployment of profitable public access networks. Our solutions allow providers or venue owners to create billing plans using credit cards, scratch cards or that enable monthly subscriptions—then bill by a host of different parameters including time, volume, or bandwidth. Users can also be billed directly to their room bill through a Property Management Interface (PMS) in a hotel setting.

Advanced Security

VPN tunneling (PPTP, IPSec) remains the recommended method for transmitting data across a wireless network for mobile workers wishing to connect back to their corporate resources. The NSE features Nomadix’ patented iNATTM functionality that creates an intelligent mapping of IP Addresses and their associated VPN tunnels allowing multiple tunnels to be established to the same VPN server creating a seamless connection for all the users at the public access location. The NSE also provides tracking logs to support Lawful Intercept initiatives.

Policy-based Traffic Shaping

An NSE-enabled network allows bandwidth usage to be limited on a per device (MAC Address/User) basis. This ensures equitable distribution of bandwidth in heavily congested public access networks. The bandwidth for each device can be defined asymmetrically for both upstream and downstream data transmissions and billing plans can be associated with bandwidth levels. Users can also dynamically switch between bandwidth plans giving the network operator opportunity to sell higher bandwidth at a premium.

Global Roaming

Public access locations and networks powered by the NSE enable roaming users to access wireless broadband networks globally while maintaining a single billing account worldwide. The NSE complies with the Wireless ISP Roaming (WISPr) Best Common Practices Document by supporting both the UAM method and the required RADIUS attributes to allow roaming settlement to occur between providers.

The NSE allows the "network" to make an intelligent decision on how a user is authenticated and billed for the access by directing them to the entity they have a pre-existing relationship with. This is done through advanced NAI routing capabilities available as an Optional Module. This allows multiple providers to service one location, enabling the development of the wholesale public access model.


A key issue in the cost-effective mass-deployment of Wi-Fi HotSpot networks is an automated process to configure edge devices during initial installation as well as to centrally manage critical configuration parameters from the Network Operations Center. Such an automated process can lower site installation costs by removing the need to employ highly-trained personnel to perform the setup of the equipment.

The NSE provides a unique RADIUS-driven Auto-Configuration functionality that utilizes the existing infrastructure of a provider to deliver an effortless and rapid methodology to configure devices for fast network roll-out. Once configured, this methodology can also be effectively used to centrally manage configuration profiles for all NSE devices in the public access network.

Application Interface

The NSE provides a flexible XML interface which allows a partner to develop third party applications, which build upon the base of the Nomadix gateway technology in order to provide even greater value to the end customer. Through this bi-directional interface a number of companies have developed useful and highly targeted value-added applications in a number of industry verticals.


Nomadix delivers its NSE on a complete family of stand alone, turnkey Access Gateways through a two tier channel allowing providers to deliver the same service offering across a wide variety of venue sizes and types. Nomadix sells the AG 5600 for deployment in large public access locations such as airports, convention centers and large hotels. The AG 5600 Metro Gateway is optimized for deployment in Metropolitan HotZones and larger venues such as Fairgrounds. The AG 3100 can be used when deploying public Internet access service in mid-sized locations, while the AG 2300 provides full features for small venues, including corporate visitor based networks.
