How to get value from offering public WiFi

Free public Wi-Fi is a popular service for retail, events and hospitality providers to offer, and increasingly becoming an expected service among the public.

This needs careful thought: not least technical considerations like how to keep public networks isolated from work networks, and providing strong enough connectivity to support the user environment.

But most importantly: how should a businesses or organisation to gain value back from providing free Wi-Fi? We take a closer look at some of the best techniques.

 

Authentication & Audience Participation

Most public Wi-Fi networks expect connecting users to ‘authenticate’ by providing details such as their email address or name, and often accepting some terms and conditions of use.

This can be a fantastic marketing opportunity to gather email subscribers, demographic data, survey product popularity, or simply count customers.

Alternatively, commercial quality systems like Cisco Meraki also offer hidden gems like Facebook Authentication – in which the user has to ‘Like’ the business brand or page to gain access. This kind of authentication is superb way of increasing your visibility online by leveraging value from public Wi-Fi – effectively asking the public to become your marketeers via social media.

Physical signage and other real-world marketing can also encourage visitors to share their experience of your venue or event online while their complimentary connectivity is available.

Targeted Advertising

‘Splash’ Pages loaded on the User’s device when they first connect are customisable on many business Wi-Fi platforms, and this creates a perfect opportunity to brand the experience.

Treating this like a regular webpage offers the chance to advertise offers that are time-sensitive, updated seasonally, or promoting key products.

Alternatively, if your audience is large or targeted enough, then this space can be treated like digital real-estate, and sold on as advertising space to others looking to reach an audience.

Footfall Mapping

By combining signal strengths from different access points and triangulating the direction, enterprise systems like Meraki are able to produce animated ‘heatmaps’ of footfall around a site or venue over time.

This is valuable information it itself for public-spaces and retail centres – who rely on being able to control or exploit human travel to maximise sales, minimise costs or optimise the flow of people.

Prompt for Reviews

You’ll never get a more geographically targeted audience than this – so why not ask the key question when it counts?

To online brands in particular, digital reviews are worth serious investment, and smartphone connections direct with the customer is a perfect opportunity to prompt via the web for useful feedback or survey customer satisfaction.

Alternatively ask publicly: and gather Google Reviews, Facebook Ratings, Trustpilot Stars, or any other feedback that is of value to your organisation en masse.

WPA3 Wi-Fi Introduced

The Wi-Fi Alliance has formally announced the introduction of the WPA3 security protocol, the next generation of wireless security to protect routers and networks.

The new security standard follows hot on the heels of last year’s breach of the existing WPA2 standard, which has been in use since 2004.

WPA3, released in both ‘personal’ and ‘enterprise’ with extra protections, is expected to fix a number of deficiencies in the older WiFi protocol, including:

  • Captured encrypted data cannot be decrypted by a later breach of the password – in order to access data, a hacker must have both the password and data at point of transmission.
  • Encryption of data will be individualised, such that snooping on other devices across less secure Wi-Fi networks will be made more difficult.
  • Extra protections against password brute-forcing and ‘dictionary’ style attacks, dramatically increasingly the time cost of bulk guessing a password successfully.
  • Smart devices with no screen, including many Internet-of-things (IoT) technologies, will be administered via a smartphone screen during Wi-Fi setup.

To most end-users, the experience of entering a Wi-Fi key will feel virtually identical. WPA3 isn’t expected to actually be implemented until 2019, and is predicted to gradually replace the existing WPA2 standard on all Wi-Fi certified devices. WPA2 will continue to function, but will be steadily phased out.

Nevertheless, expect to see major manufacturers rushing to ensure their own products are stamped with the very latest security ‘WPA3 Ready’ branding.

Technology firms rush to fix WPA2 KRACK

Technology firms are urgently issuing fixes for the WPA2 KRACK (Key Reinstallation Attack) thought to compromise the WPA2 encryption used in most WiFi routers and other wirelessly enabled devices.

The exploit, discovered and published by Mathy Vanhoef, a Belgian security expert for Imec-Distrinet, Ku Leuven, has caused serious alarm amongst cybersecurity professionals due to the widespread use of WPA2 across millions of items of networked hardware around the World.

Vanhoef’s website, detailing how the the WPA2 KRACK works, demonstrates on video how an unfortunate Android smartphone can be tricked into re-installing an all-zero encryption key, which makes de-crypting data transmitted from the device possible. 

Security guidance remains to continue using WPA2 (rather than reverting to an older encryption standard) and to install the latest WPA2 KRACK security updates from manufacturers as soon as they are available.

A number of key technology vendors were notified in August, giving them some time to prepare. Microsoft are reported to have adjusted “how Windows verifies windows group key handshakes” to fix the issue. Apple and Android are yet to specify exactly when patches will be available, although both are understood to be working on a secure fix to be made available in coming weeks. The more responsive hardware developers, including Cisco and Ubiquiti, yesterday began issuing guidance and new firmware for their wireless equipment.

The Wi-Fi Alliance, the international organisation dedicated to developing Wi-Fi technology, have essentially argued that there is no need to panic. There is no evidence of the extremely serious hack being deployed outside test conditions (yet) – although it’s probably only a matter of time before someone attempts to do so. Because Wi-Fi relies on physical range, it’s likely this could target public Wi-Fi and other easily accessible networks. For this reason, users are (as always) reminded not to use public networks for sensitive tasks, such as online banking.

It’s clear from the increased publicity surrounding the discovery that major vendors of network equipment will be under pressure to issue the required WPA2 KRACK security patches.

However, the underlying vulnerability also threatens a wide range of wirelessly connected internet-of-things (IOT) devices – including everything from CCTV to smart-fridges – such that it’s unclear just how widespread this latest security flaw will actually prove.

How Lineal provided Free Wifi to Barnstaple Town Centre

 

Over Christmas 2015/16, Lineal launched a technical trial to provide free, public-access Wifi across Barnstaple Town Centre.

The pilot scheme, which took place during the busiest shopping period of the year, saw our team solve a number of technical challenges: scoping sites for Wifi access points, installing suitable hardware and managing network connectivity for shoppers and visitors to the town.

With generous support from Barnstaple Town Centre Management (BTCM), North Devon Council and M&E Alarms, we delivered a free wifi network connected to by more than 400 people each day at peak usage.

To build the network itself, we used Cisco Meraki MR-66 ruggedised outdoor routers, fixing a ‘mesh’ grid of interconnected access points high on selected buildings owned by local businesses who agreed to take part. Visitors to the town could connect from any smartphone or other wirelessely enabled device, via a special ‘splash’ page.

Managing Director of Lineal, Mike Matthews, explained: “We wanted to attempt an ambitious project which would benefit our local area. Wider connectivity opens up new ways for people to find out information about upcoming events, for local businesses to advertise, and for visitors to our town to share their enjoyment of Barnstaple with friends and family over social media. There are many possibilities.”

Throughout the trial period each access point also collected anonymised location data in real-time. With as many as 20,000 wirelessly enabled devices moving within Barnstaple town centre during a 24 hour period, the free Wifi Project was also successfully used to measure footfall patterns in public places, which could one day be used to help local authorities plan for busy periods.

Although the pilot project has now ended, team members from Lineal presented the initial findings to the Barnstaple Town Centre Management, North Devon Council and Devon County Council in February 2016, with a view to launching the network as a more permanent asset for the town in the near future.
