Barcode, Event, IT, QR Code

QR codes link the virtual world with the real world. Like many technologies it sounds abstract but once appreciated it can be very powerful for the events world. A few of our customers have been asking what, practically, can one do with them…so we have listed a few applications.

For those of you who haven’t come across them before, QR codes are the next generation of bar code. A normal bar code contains just a set of numbers which can be quickly read by a computer (or you can read them yourself if you are so inclined) whereas as a QR codes can contain text and context information, such as identifying the text as a URL or an email address. QR codes can be generated for free (here is one example) and many apps exist to scan them just by taking a photo from a smartphone.

Using them in print media – Imagine you are launching a press campaign for a new event. You want people to go to a website to sign up for the event. The print advert cost you a bit so ideally you want to know how many people register as a result of seeing it. Normally to achieve this you would either use a hyperlink for registration which is unique to the advert (which can be hard to remember) or ask those who register where they saw the advert (good luck getting someone to fill that out). Now imagine you create a QR code which links to a registration form with a special string which highlights the exact advert. If someone wants to register whilst reading the advert they pull their phone from their pocket, take a photo of the QR code and they are immediately connected to the hyperlink.

Linking them into social media – Although this requires a little bit of technical knowhow a lot of companies are now linking QR codes with a Facebook ‘Like’ so that it can be instantly shared with someone’s friends. By using a small application interface (in Facebook) people viewing a poster at an event can ‘like’ it which then presents itself in their Facebook profile (they need to input their password and username). The event attendee would take a photo of the QR code which would then link them to the sign in function for Facebook.

QR code in use

Used as a feedback link – I saw this recently on Eurostar. Just a simple poster as you leave their luggage area which reminds customers with any feedback to please send them a text message. Text is great, however on the same poster you could include a QR code with a specific email access. Much quicker for the person walking out of the area who doesn’t have time to stand and type in the email address to wewantyourfeedback@someverylongdomainname.com is to use a QR code

Put them on your business card – QR codes can contain a full digital business card, so no longer do your contacts need to type in your information.

Payment systems (and beyond) – Starbucks has a great example of this application working now. You pay for a coffee through their smartphone application then simply show the barista the QR code. They have a scanner at the pay point which confirms the QR code against their system and you get your super latte mocca frappe. Imagine that working at a bar? Or for a customer willing to pay access to VIP shower facilities? Endless possibilities.

Conference Wi-Fi – Ignore at your Peril

17 Feb 2011

‘Good news travels fast, bad news travels faster’ has never been a truer saying in the social world of retweets and ‘likes’. I wasn’t at Mobile World Congress this week but I did follow the stream of tweets originating from there. Amongst those tweets were comments about poor Wi-Fi coverage, I have no idea whether the Wi-Fi was poor or not but with a few negative comments bouncing around the ether it can quickly lead to the perception that another large conference has not taken it’s audiences desire to use mobile technology seriously – particularly damaging when it’s a mobile technology conference!

The chances are it was a few people having localised problems with their devices but its another example of the damage that can be inflicted very quickly when attendees feel they are experiencing a poor service. Both Apple’s Steve Jobs and Microsoft’s Steve Ballmer have also experienced the pain of poor launch event Wi-Fi in the last year, with hundreds of press watching and commenting, and the result that the issues became a bigger headline than the product itself. So, what can you do to avoid the issues at your conference or launch?

1) Know your audience – What type of press is attending? What’s the demographic of the audience? You might think only tech events need technical services but many launches these days need high quality internet, for example London’s Fashion week had a huge amount of live blogging along with video streaming, posting of images and tweeting. Understanding these aspects is the starting point for working out what level of service is required.

2) Be realistic about capacity – Poor Wi-Fi will frustrate people more than no Wi-Fi, and good Wi-Fi with no sensible internet capacity is just as bad. Mobile data demand is growing exponentially but far too often the capacity required is under called. Budgets may be a challenge but often the problem is exasperated with last minute bookings which have a higher cost. Internet bandwidth is not something that should be an afterthought, it should be up towards the top of the requirements.

3) Work with social media – Working on the assumption that people who are tweeting and blogging will look after themselves is missing the opportunity to engage with a huge audience. People will tweet regardless so it is critical to get involved to address comments. For example if someone tweets the Wi-Fi is bad, wouldn’t it be great to send a support engineer over to check everything is OK with their system? They are then far more likely to post a positive comment.

4) Offer a variety of options – Although Wi-Fi is great there will always be someone who has a problem getting connected, having somewhere for people to go and plug a cable in as a fall back creates a great impression. Couple that with support staff who understand the common issues around firewalls, VPNs, connection agents and drivers and the press will feel they are being catered for.

5) Partner with the venue – Don’t just accept that the venue provided Wi-Fi will work for you and your customers’ requirements, in the vast majority of cases this is not the case. Check they have dealt with a similar scale of event, understand how they intend to support users, question their capacity. High capacity Wi-Fi is a very different game to a typical casual usage Wi-Fi installation and many common wireless products are just not up to the job.

It may be a cliche that we ‘live in a connected world’ but we do, which is both powerful and dangerous, and most importantly is something that cannot be ignored if you want to maximise good exposure.

Mobile Apps at Events – Learning from the Past

11 Feb 2011

Android, Event, Festival, iphone, Mobile Apps, Smartphone, Wi-Fi

It’s almost expected now that along with an event comes a mobile app for the iPhone, Android or other platform. At most events, certainly the larger ones and those outdoors in temporary locations, the enthusiasm for a mobile app soon wanes when the user finds that all they get is out of date information or error messages saying ‘no connection is available’. The simple fact is that the mobile networks cannot deal with data traffic effectively at event sites and this more than anything else leads to poor reviews in the app stores.

The two obvious approaches to fixing this problem are to either improve connectivity or make the app stand-alone so that it doesn’t need connectivity once it is installed on the phone. Improving connectivity via the mobile networks is not really an option, as even with temporary mobile towers the capacity and connectivity available is not good enough to deal with the sort of high density found at event sites and the cost becomes very prohibitive. A correctly designed Wi-Fi network can deal with the capacity and provide a much better user experience but this option may not always be possible in terms of budget.

I have seen more recently a trend to make event apps stand alone, driven most likely because of the connectivity issue, but there are two major flaws in this approach. Firstly the whole point of a mobile app is to offer something different, unique, current and interactive. If you take away the connectivity then you are left without most of those features and risk an app that is stale which, after an initial browse, is closed and forgotten about. The social media generation live in a connected world with a thirst for live information and that feature is what can make an app much more than an electronic programme guide. The second issue with a stand-alone app is that it doesn’t address the problem of downloading the app itself. Although you can try and persuade people to download the app before the event the fact is many will want to do it at then event itself and with a stand-alone app it is often the case that the install is even larger than a connected app as everything needs to be in the app download meaning the download is more likely to fail (and if too large is not allowed to be downloaded) over a mobile network.

There is a middle ground in all of this and it takes a leaf out of ‘mobile development’ from the 1990s when mobility was a laptop (more akin to a briefcase) and a 28k dial-up modem, it seems a lifetime ago now but it did teach developers an approach which is still very valid today. The approach is not earth shattering but it is too often forgotten by many of today’s applications, simply put it just means never assuming the network is available! More specifically it means factoring in the following design aspects:

Ability to operate with or without the network
Graceful degrade when the network connection fails
Local cache of data which updates when the network is available
Progressive and background downloads so that the user is not waiting for ages unable to do anything
Differential download of data so that only new data is sent
Avoiding or minimising ‘auto refreshes’ to reduce network load

Effective implementation of the approaches above will provide a much better user experience as the app operates when the network fails but the user still gets updates when they move into an area with connectivity, with the updates trickling in quietly in the background. There are some very good examples of mobile apps available but far too many still fall over or perform badly when network connectivity is poor and that’s just unacceptable for an event app.

Taking Event Comms Seriously

The Event Production Show 2011

Having spent a couple of days last week at the Event Production Show talking to existing and potential customers it’s interesting to note down some of the common themes we are hearing and challenges people are facing around technology.

Underpinning many of the discussions I had was an increased focus on the importance of event connectivity. It has moved from a nice to have, through must have, to critical as more and more services rely on it. With that more organisers now understand some of the challenges in terms of capacity and performance and, for example, weaknesses such as ‘upload’ performance on ADSL and the problem with latency on satellite, which renders VPN and VoIP services nearly unusable. We are not locked to a single provider or service and can offer everything from BT lines through to satellite, WiMAX and fibre, depending on requirements, budget and time. Understanding what capacity is really required is a critical step in the process.

The cost of connectivity remains a concern but there are a few ways to keep cost under control, firstly book early! The shorter the notice the less options there are, and at short notice services often need to be expedited leading to significant extra charges. Secondly consolidate, reduce the number of lines by using VoIP and use a proper managed network to share and control bandwidth effectively. Lastly look at longer term options – if you are going to be using the same site for several years it is often cheaper to install permanent connectivity rather than temporary services as the main cost is the installation, with the annual rental often much lower than the cost of reinstalling each year. We now do this for a number of customers and manage all the technical and paperwork aspects so that the service is available when needed.

Another common comment was ‘we tried to use 3G but it was a disaster’. Running event connectivity on 3G is a highly risky strategy, at best it is likely to give poor and intermittent performance and more commonly during an event it is completely unusable, even when additional mobile towers have been placed on site. If an event needs connectivity then it needs managed connectivity, not ‘cross your fingers and hope’. The difference in cost between using a 3G approach and a basic professional set-up is not as large as people often think and there are many benefits.

Over the last couple of years the interest in site-wide attendee Wi-Fi has increased significantly and that trend continued this year. Alongside the general desire to allow people to stay connected the other big driver is the use of smartphone apps. Providing an application at an event with no additional connectivity generally results in unfavourable reviews as the performance is poor. The good news is that in many cases extending Wi-Fi internet coverage to the public is not as big a problem as it may seem, provided it is done correctly using appropriate hardware and managed networks with features such as traffic shaping. There are various models for cost recovery including ‘hotspot’ type charging or advertising and branding.

Integration of services is another key issue with production, ticketing, merchandise, bars and catering, security, etc. all having their own specific needs. Bringing all this together successfully requires experience and extensive IT knowledge. Making sure everyone is talking and sharing requirements is part of the service we provide so that you do not need to worry about the fact that the ticketing company require an onsite SQL database and a site-to-site VPN connection to a hosting centre you have never heard of!

Event IT is it’s own specialist area, you wouldn’t dream of letting any old person run your sound system, provide power, operate ticketing or put up marquees, and the same is true of event IT if want a dependable service which meets your needs.

The Etherlive stand saw a steady stream of enquiries for dependable event IT services

Passes Ready for the Event Production Show

Event, Event IT, Event Production Show 2011, Festival, RFID, Showground, Trade Show, Wi-Fi

The Etherlive team are now in the last stages of planning in preparation for the Event Production Show at Olympia on 2 – 3 February. We are on stand 620, on the right hand side of the main isle not far from the entrance. As usual the team will be ready to answer questions, discuss services and demonstrate equipment. With a Royal Wedding this year and the Olympics next year it is important to get services booked early – we are already seeing a knock on impact from these events, for example lead times are increasing for telecommunication services and this will get worse during the year.

Alongside our normal array of solutions for connectivity, communications, monitoring and interactive technology we will also be demonstrating three new services:

Crew Accreditation System – A contact-less RFID card (or wristband) system which makes managing crews simpler. The system uses a PC or touchscreen terminal to manage crew as they book out keys, radios, plant equipment and doubles as a crew catering system replacing those pesky paper vouchers. Multiple terminals can be used over the site such as in the catering tent and production offices. All the data is easy to manage allowing production to forecast catering requirements and track items quickly.

Dynamic Secure Wi-Fi – There has been a lot of press recently about the security of wireless networks and even though we already have a very secure system we will launching an even better solution. What’s great about it is that it’s easier for the user but more secure as every user has their own unique encryption key. Aimed at events when privacy is critical it will reside alongside our existing range of wireless services so that you can decide what level is appropriate for your event.

Communications Tower Light – Not completely new as it is in its second year of use by Etherlive but this palletised, environmentally tower light was a great success during the 2010 season so we have been improving it further. Supporting Wi-Fi and cabled networking, public address and CCTV from one unit, it is perfect for quickly deploying technology services in areas with no power. The 2011 unit now has multiple camera options with a new higher zoom and motion tracking enabled camera added to the range; and if you need high density outdoor wireless there are options for up to 750 simultaneous Wi-Fi connections off of one unit.

Take a moment to register here if you plan to come along to the show to speed up getting in and of course if you want to set-up a specific time to meet you can get in contact beforehand.

We hope to see you at the show!

Wireless Security – Any Need to Panic?

17 Jan 2011

Encryption, Event IT, Festival, IT, Press Centre, Security, Technology, Wi-Fi, Wireless

The issue of wireless encryption ‘cracking’ has been in the news again recently thanks to Thomas Roth and his claim to be able crack WPA-PSK passwords in a matter of minutes. The basic methods used are nothing new, primarily a hybrid brute force and dictionary attack, which essentially is like you sitting at a computer and trying every word you can think of as the password. What was different in this case is the use of cloud computing to harness enormous processing power – enough to try 400,000 passwords per second bringing the time to guessing the password down considerably. This all sounds rather concerning, but is it really?

If you fit the best lock money can buy to your front door and then you leave it on the latch, can you really complain when someone opens the door and burgles your house? The important thing with encryption is the complexity of the password as the time it takes to crack a password depends very significantly upon the password strength. Roth himself said “If [the password is] in a dictionary it’ll be very fast, but if you have to brute force it and it’s longer than eight characters and its complexity is okay, it’ll take a very long time.” By ‘long time’ he means years and years, and the longer the password the longer it takes, in fact exponentially longer.

Security is only as strong as the weakest link

So, nothing to worry about then?…well not quite when you consider the way WPA-PSK is often used. The clue is in the name – PSK stands for Pre-Shared Key – and as it suggests the key is shared between all users. If you take a typical event site where organisers, press and crew require a ‘secure’ wireless network often WPA-PSK will be used, but it’s often not as secure as intended for two reasons.

Firstly, the password or key is being given to many people and it only takes one person to release the password into the wild and the whole network is compromised. Once compromised the only way to secure the network again is to change the shared password which means all users need to be notified of the new key, not very practical in the middle of an event.

The second issue is that because the password is being shared between many people generally a short, easy to remember one is used, opening up the network to the type of attack described above. Visit many media centres, event HQ’s etc. and you will see the network password printed on A4 pieces of paper stuck to the wall.

Network security is often seen as a hassle, along with the “it won’t happen to us” mentality but there are more and more reasons to take it seriously. Prior to the news about the WPA-PSK crack there was also news about a plugin for the Firefox browser that could ‘listen’ to other users’ data on a wireless network (either an open network or one where the key is known). Increasingly at events more and more data is transmitted across the network and much of it is sensitive. Yes there are secondary mechanisms such as VPN and SSL that are used to protect some data but often you will find file shares, websites and other data all unencrypted and open to see on the network.

We do take network security very seriously and have been offering individual user names and passwords for network access for several years which gives us access control with a much better level of granularity, along with the ability to provide a full audit of users. For 2011 we are going a step further and at the Event Production Show in February we will be launching an additional service known as DPSK or Dynamic Pre-Shared Key. Using this service once a user logs onto the network they are transparently given a dynamic, unique encryption key. This means that all users have a different (and very strong) encryption key, ensuring all data transmitted is well protected and users do not need to know the key or share it with anyone. All the user needs to know is their username and password (which stills needs to be ‘strong’) but if that user’s details are compromised the only impact is to that user and that user’s account can be quickly blocked.

We understand that every event has different needs and aspects such as network security are a balance between risk and complexity so we have developed a range of solutions to meet those different needs. If you are concerned about the security of your IT systems at events then drop in for a chat at the Event Production Show or contact us for a discussion.
