Wireless Technology

Internexus has spent the last 6 years researching and developing and most recently building a new national core, distribution and access network.

Now, Internexus are in the enviable position of being able to implement a brand new network based on the latest available technologies. Explained in the simplest of terms, this means that Internexus does not suffer with having to maintain and upgrade a legacy network as other network providers do, meaning that they can offer the latest services and broadband speeds to end users.

Core network

Internexus operate their core network using national dark fibre that is lit up with DWDM technology. This allows Internexus to multiplex protected optical wavelengths around the UK and provide Terabits of capacity to the network. In addition, Internexus has the capabilities of being seamlessly upgraded as and when demand requires, within a very minimal timeframe and with no down time.

Radio device technology

Within the distribution network, Internexus use resilient ring topologies that are constructed using radio devices based on E and V Band milliwave technologies that Internexus specially developed with a strategic partner. These devices are now capable of delivering 6Gb over a single radio and can provide SLAs based on 99.999% uptime.

Following this success, Internexus are continuing to work with their strategic partners and have now funded the design of a radio that can provide 12Gb based on the latest radio modulations and standards. Internexus will be moving forward shortly with the construction of these devices.

The last mile

At the access level / the last mile, Internexus use the latest 802.11 wireless standards to deliver a full service to the end users on a point to multipoint basis. Internexus has learnt that trying to flood a residential area with wireless seldom works as other providers have proved. As such, a more advantageous approach is to deliver a point-to-point signal to the end user using a radio receiver located at the end user's premises. Again, Internexus has worked with their strategic partner to develop enhanced carrier class wireless transmitters that can deliver up to several hundred megabits per second to large collections of end users.

Why radio?

Radio technologies have been given bad press, but when implemented correctly with the appropriate resilience and network capacities, radio is the best option within the distribution and access networks, and Internexus see this being the standard to work to moving forward.

Based on the strict network planning and topologies that Internexus have implemented within their distribution and access network, issues such as weather do not have a knock-on effect to the end users’ service. Internexus have developed these planning strategies based on over 6 years’ experience in the field and with this knowledge and experience Internexus are now operating services that adhere to the strict SLAs. These include the 99.999% uptimes that enterprise level business customers require to operate.

A proven example of this technology being used at this level is the New York stock exchange. They moved away from fibre technology to radio technology as the latency times between sites using radio are less than fibre based technologies.

Converged technologies

Internexus employ carrier class layer 2 - 7 equipment within the network. This can provide enhanced services such as DPI and content filtering to keep end users safe.

Internexus are also a voice carrier and are fully interconnected into the UK PSTN using TDM interconnects and host geographic number ranges for every city and town in the UK. Internexus uses a co-developed internal soft switch platform that provides a complete set of class 5 services to end users.

The Internexus network has been developed with converged technologies in mind and it can therefore support voice, data and IPTV services and will allow for further technologies to be on-boarded as more and more move to using IP as their communication method.

Using the aforementioned employment of the latest technologies and based on Internexus’ own developments as well as the expertise of their strategic partners, Internexus are able to provide a true alternative access network to that of the legacy network providers.

Internexus have built the network with wholesaling in mind and want to open it up so that end users can benefit from competition whilst still enjoying the benefits of what the technology can bring.
