Axell Wireless announced enhancements to its portfolio of public safety coverage systems at the Critical Communications World show in Paris last week (21-24 May 2013).
Spectrum Analyser facility
The new Spectrum Analyser facility is designed to lower the costs of set up and operation associated with TETRA network deployments, while its LTE range of solutions advances the mobile data capabilities of public safety networks.
The new fully integrated Spectrum Analyser solution provides operators with an accurate view of all available parameters - including, bandwidth, frequency range, and power – allowing for remotely controlled network optimisation through a simple user interface, as well as a significant reduction in troubleshooting and maintenance time and costs.
Ian Brown, CEO, Axell Wireless (pictured) explained to Wireless: ‘What this allows you to do is by connecting to a web interface, you can remotely scan the spectrum of a base station and see if there are any interference issues. Previously, you would have had to go out to the site and measure it there, so this saves a lot of time and money.
‘With the continued enhancements to our digital TETRA repeater range we are working to drive down operator’s roll-out and operational costs while improving the planning and management of their networks.’
LTE-ready for next generation public safety networks
Axell Wireless has already pioneered the use of LTE technology with cellular operators through the provision of multi-band digital repeaters and Fibre Distributed Antenna Systems (FibreDAS) to deliver mixed 2G, 3G and LTE services.
Brown said: ‘We have been supplying mobile phone operators with LTE technology for several years now, so it is not that difficult for us to tweak it for public safety. No one is using LTE for public safety in Europe yet, but it means we now have the equipment ready when they do, I can see public safety organisations using TETRA for voice and LTE for data in the future.’
Axell’s LTE equipment has been successfully deployed in challenging coverage environments all over the world including stadia, tunnels, shopping malls and large commercial buildings. LTE technology also offers massive bandwidth capability for public safety operators to stream live data and share high-resolution images in the most demanding of physical environments.
Axell’s coverage products have the capability to combine the highly secure and resilient TETRA infrastructure with a high-capacity data pipe based on LTE, whilst providing segmentation from the commercial operator’s network.
Brown said: ‘Our LTE-ready solutions further enhance public safety communications with high-speed data capability. Axell DAS and coverage systems can support cellular and public safety frequencies simultaneously allowing, for example, both voice using TETRA and mobile data transmissions using dedicated LTE bands on the same DAS.
‘Axell’s technology provides users and operators of public safety networks with an increasing range of flexible solutions for handling secure voice and data services.’
Axell Wireless’ digital products are based on SDR technology and make use of patented digital filtering techniques. These techniques allow operators to make instant changes to the functionality of their coverage systems via remote links within existing hardware, providing flexibility, lower-cost deployment and maintenance.
Axell Wireless CEO Ian Brown on the acquisition by Cobham
Axell CEO Ian Brown explains that following the acquisition of the company by Cobham it will be ‘business as usual’ at Axell with the same management team continuing to run the company. The company will continue to trade as Axell and become a separate division within Cobham.
Brown says some 70% of Cobham’s £3bn turnover business is in the defense sector, but it is looking to expand the commercial side of the business. ‘Axell is really the only substantial independent, so if you want to get into the DAS space we are the one to go for.
‘Cobham has a very strong balance sheet, which they will use to penetrate the commercial world and they will help us grow faster. With their defence and security credentials they can open doors for us and we can open doors for them in the commercial world,’ says Brown.
Brown sees some technical synergies between the two companies. For example, Cobham has very advanced interference cancellation technology and it also has a wide range of antennas, which he says will be of interest to Axell customers.
‘Our equipment needs antennas for the DAS system, something we don’t sell today – we make recommendations to customers instead. But Cobham does have antennas, so I can see us offering that portfolio to our customers,’ says Brown.
