Wi-Fi

Wi-Fi has become the default and preferred technology for individuals to access networks wherever it is available, whether shopping, eating, and travelling or at work. Wi-Fi systems have evolved considerably in functionality and capabilities over the last few years and there are huge amounts of information available.   Wi-Fi is no longer just a must have connectivity service but a complete revenue driving platform and a must have business requirement.

Hughes Europe provides a comprehensive portfolio of Wi-Fi solutions, where it is just for business connectivity, to gather analytics for business and customer intelligence or as a revenue generator for your business. With cloud and on premises service we can provide Wi-Fi for every requirement.

To find out more about how Wi-Fi can generate revenue for you, reduce operational costs and provide a greater user experience come and talk to one of our technical consultants.

Over the last 20 years Wi-Fi standards have evolved and are continuing to evolve to cope with the enhanced requirements and expectations of users for higher data transfer rates, better security, enhanced Quality of Service (QoS), ease of manageability, and support for more streaming based services.

The IEEE 802.11n standard, which became available in 2008, has been very popular among a variety of Wi-Fi products including access points (APs), laptops, smart tablets and smartphones due to the increase in data transfer rates from 54 Mbps to nearly 600 Mbps. As users became use to these higher speeds their service experience and expectations changed.

There is the demand now for gigabit like speeds over a Wi-Fi network through the need for higher data speeds fuelled by new applications that allow users to view and share high volume files and streaming data, such as videos, high-definition graphics, social media and Augmented Reality. These new applications along with Bring Your Own Device (BYOD) and Bring Your Own Content (BYOC) have also increased the need for ensuing QoS for all applications. In addition with many companies moving away from fixed line connectivity internally to wireless networks the ability to have higher networking speeds and security is becoming of greater importance.

If you are looking to develop your Wi-Fi network and launch new business applications then the latest Wi-Fi technology 802.11ac with backward compatibility to the earlier 802.11 standards should be considered.  Deployed correctly it should pay for itself, create new revenue streams for you, provide an enhanced customer experience and a better working environment for employees.

To provide higher throughputs MU-MIMO is used in the latest Wi-Fi Access Points.

MIMO - “MIMO” stands for “Multiple-Input, Multiple-Output”, and refers to the way bandwidth is broken up by a Wi-Fi router and pushed to individual devices. Routers that use “SU-MIMO”, or “Single User, Multiple-Input, Multiple-Output” only allows one device to receive data at any given time. This means that there are likely to be delays for users if data streams are started at the same time. The more devices that connect to a Wi-Fi network the slower it moves, this is often experienced with mobile POS terminals where there are many customers connected or trying to connect to the same Wi-Fi network

MU-MIMO - Multi-user, multiple-input, multiple-output technology used in Wave 2 Access Points allows a Wi-Fi router to communicate with multiple devices simultaneously. This decreases the time each device has to wait for a signal and dramatically speeds up the network. With more transmit and receive radios better data transfer and user connectivity can be achieved

  • 2x2 MIMO devices with dual antennas and radios will be able to communicate via two streams of transmit and receive.

  • 3x3 MIMO device with 3 antennas and radios is capable of transmitting and receiving via three streams

  • 4x4 MIMO device with 4 antennas and radios is capable of transmitting and receiving via four streams

All these streams afford the device more bandwidth capacity when downloading and uploading data to and from the wireless network.  Hughes can provide Wi-Fi Access Points with multiple radios to suit your network requirements and provide you with the best performance for your Wi-Fi environment.

Wi-Fi Security - With Wi-Fi being an open access platform and rogue users trying to link in unofficially to Wi-Fi networks the need for a secure environment is a must for any Wi-Fi deployment.

The Hughes Wi-Fi service uses industry-leading wireless intrusion prevention system (WIPS)to provide the most comprehensive protection from wireless vulnerabilities and threats. The service uniquely automates wireless threat detection while minimising false alarms and enables detailed wireless threat prevention both over the air and on the wire. If you have an existing Wi-Fi deployment the service can be deployed as an overlay service or deployed as a new service

Automatic Device Classification - Based on your policy for authorised WLAN, the Hughes Wi-Fi service can automatically classify Wi-Fi devices into Authorized, External, Guest and Rogue.

Comprehensive Threat Coverage - The Hughes Wi-Fi service using Mojo Networks APs provides comprehensive protection from wireless threats, including most types of Rogue APs, unauthorised client connections, ad-hoc connections, misbehaving clients, Honeypot or Evil Twin, MAC spoofing, and DoS attacks. Live alerts provide real-time notifications about the type and severity of threats

Automatic Policy Enforcement – With APs detected and classified into the appropriate policy we can enforce Wi-Fi and no-Wi-Fi policies without the need for administrator intervention. Using a suite of context-based wired and wireless prevention techniques, Mojo AirTight can not only block unauthorized Wi-Fi connections to your corporate network, but also block corporate Wi-Fi client devices from misbehaving, e.g., connecting to unauthorized Wi-Fi, without harming or disrupting legitimate neighbouring Wi-Fi networks

 

Location Tracking – By using Mojo’s patented location tracking technology built into their access points that uses a combination of stochastic RF fingerprinting and triangulation the Hughes Wi-Fi service provides accurate location tracking to pinpoint the physical location of a Wi-Fi device on a floor map.  This allows you to track down and take action against Wi-Fi devices that are violating corporate security policies. The technique is self-calibrating and does not require RF site surveys.

Geo-Fencing – The Hughes Wi-Fi service can be used to define and cordon off specific physical areas, as no-Wi-Fi zones and alert security teams if Wi-Fi devices are detected inside or within a pre-defined proximity of the protected area. Such Wi-Fi devices can also be automatically quarantined to block any communication with them and track their physical location on a floor map

Compliance Reporting – Automated or manually PCI reports can be generated for the wireless network as required around your PCI regulatory commitments.  This has the ability to negate the need for PCI consultants to visit every site to carry out a survey providing significant cost savings for you.

Background Scanning - To identify where a Wi-Fi AP is legitimate or a rogue device, wireless APs need to be able to scan the airwaves.  There are two options, background scanning or real-time scanning.  This can be provided by either the existing radio taking time out to scan either the 2 GHz or 5 GHz frequencies or having a dedicated radio doing this full time.  Both scenarios allow you to scan for rogue devices but background scanning can take some time to identify a rogue device where full time scanning will identify a rogue device in real time.

Application Visibility - With more and more applications going over a Wi-Fi network especially high bandwidth streaming applications the need to identify the bandwidth hogs or applications that should not be running across a corporate network is of greater importance today. Application visibility available across the Hughes Wi-Fi service range lets you monitor every application running across your WLAN. Through an intuitive, visual dashboard historical and real-time application use can be seen, helping to uncover usage (and abuse) across the network. Over 1400 unique applications can be monitored across the wireless network and more will be added as they are identified. Layer 7 deep packet inspection ensures accurate classification and filters can be created by application name, type, total usage, percentage usage and threat level, with application usage as seen as granular as three second bursts

 

Trouble shooting -  Working closely with our Wi-Fi partners the Hughes Wi-Fi service is building Cognitive Networking into our portfolio which uniquely harnesses the power of cloud, big data analytics, machine learning, software-defined networking, and cognitive computing to deliver the best experience possible to Wi-Fi users and reduce the operational overheads of IT staff.

Network Baselining – Using Mojo Aware as part of a Hughes Mojo Networks Wi-Fi deployment we can provide direct and real-time insight into the experience of Wi-Fi clients across your network. Know when and why clients fail to connect to the network, track latencies of network services such as AAA, DHCP, and DNS. We can drill down with live and historical client connection logs to proactively know when and why certain clients may experience poor performance.

Cognitive Computing - Using machine-learning algorithms on the network analytics it collects, Mojo Aware available on our Mojo Networks Wi-Fi service baselines your network, i.e., establishes what’s “normal” and automatically detects and highlights anomalies. When possible it fine-tunes the Wi-Fi network to optimise the user experience or provides recommendations to resolve network problems. Going beyond machine learning, Mojo Aware comes with in-built domain expertise and protocol-level intelligence. It automatically detects and classifies in real time when Wi-Fi clients fail to connect and pinpoints the root cause; if it is related to Wi-Fi or to a network service such as DHCP or DNS or a client device or an application. Similarly it automates root cause analysis of poor performance, e.g., poor coverage, high retry rate, sticky clients.

Client Emulation and Network Profiling - Dependent on the type of Wi-Fi AP deployed we can help you experience your network before your users do allowing you to stay ahead of the game. We can use the multi-function 3rd radio available in specific Access Points as a client and run tests to identify and fix problems before users experience them.  The service can also be provided to validate your network’s readiness for supporting new business-critical applications.

Intelligent RF Optimisation - Unparalleled visibility in both 2.4 GHz and 5 GHz enables automatic RF optimisations such as band steering, smart steering, auto channel selection or auto transmit power control to maximise Wi-Fi capacity. Real-time application performance is further enhanced with multicast-to-unicast conversion and smart blocking, pruning and optimisation of broadcast and multicast traffic.
