The last couple of years has seen a major shift to ‘cloud computing’ driven by a combination of the expectation of connectivity everywhere and the explosion of users wishing to easily share content between several devices. On the whole the use of cloud services such as Dropbox, Box, Google Drive, Sky Drive and cloud hosted business applications such as Salesforce, Office365, Adobe and even Sage to name a few, can be great for companies, providing the well documented concerns around security, data protection and availability are addressed appropriately.

There is, however, a grey lining to the cloud when it comes to events – the impact cloud services have on the event infrastructure. The internal infrastructure in terms of Wi-Fi and wired connections is not the concern, any well designed network should be able to handle that, it is the internet connectivity aspect. The additional loading that cloud services create is having a significant impact on the capacity required and many events and customers are not factoring this into plans and budgets.

Cloud services change the usage characteristics of internet connections, creating much more demand on the upload capacity compared to traditional browsing, this means that ‘synchronous’ connections need to be used where the upload and download speeds are more closely matched compared to ADSL where the download is much faster than the upload. Overall the capacity of the internet connections need to be higher too because everything is going back and forth to the internet. For example a user sharing a 10MB site plan to ten others will generate 10MB of upload traffic and 100MB of download traffic because it will synchronise to each user separately – this may not seem a lot but scale up to a whole site across all users (with multiple devices) and all services and the numbers get very large very quickly. Scrimping on the connectivity for a corporate training event where all 200 users are set to use a cloud service is a recipe for disaster as the user experience will undoubtedly be poor.

Storm
Cloud based services can cause a storm with event internet requirements

Adding more capacity is generally the easiest route but the jump in cost can be higher than customers expect because of the need to move to synchronous and low contention services such as EFM (Ethernet First Mile) and optic fibre. In some cases wired connectivity is limited so additional wireless or satellite capacity is required and these have their own requirements which need to be factored in early on in planning. Newer services like BT Infinity do help in some cases but it should be remembered that although the headline numbers look good these are consumer focused services which come with high contention ratios (meaning a high risk that performance will be much lower than stated at busy times) and there is no guarantee on the service.

Slowly cloud based services are realising there is a need to be able to distribute load and are making available the ability to provide local caches of data which will help over time but we are some way off this being easily available for most services. In the mean time understanding what services are being used and undertaking capacity planning is essential so that the correct level of capacity can be put in place.

Overall cloud services can be very cost effective but as the saying goes there is no such thing as a free lunch!

The statement above is the headline of an Inquirer story published on Monday 6th Feb based on information taken from a PDF distributed by London 2012 to help businesses prepare for the Olympics. The headline may be a bit sensationalist – ‘may cause internet access to be slow for some’ isn’t quite as eye-catching – but there are some valid points to take on board:

1. The main issue is the expected increase in volume of usage of the internet by locals and visitors alike. The problem though is not the internet itself (or more correctly the ‘backbone’ of high capacity links that form the network), it is the local broadband access via services like ADSL and cable which may become overloaded at exchanges and concentration points. Many of these services are based on a ‘contention ratio’, sometimes as high as 50:1, which relies on not everyone using their internet connection at the same time for good performance to be maintained. Business ADSL/SDSL services typically have a much lower contention ratio (around 10:1 or lower) and if you are relying on internet access during the Games it would be wise to check this for your provider. At events we operate at we typically only use services which have a 1:1 contention ratio to eliminate this risk. Services such as optic fibre and leased lines in general should also have a 1:1 ratio.

2. Exchange congestion is another concern as many broadband ADSL providers use BT infrastructure to provide their service. Again it can be the case that there is element of contention across the services leading to a slowdown. This area is harder to deal with but providers who are using an LLU (“Local Loop Unbundled”) service have more control over their capacity so should be able to manage performance better. Again at events we will always an LLU service wherever possible and in fact in many locations we do not traverse any BT infrastructure other than the ‘last mile’ copper pairs or fibre.

3. Site-to-Site internet links are a concern for businesses where they have multiple sites connected via a VPN (Virtual Private Network) which traverses the internet, as any general congestion will also impact their site to site links. This is a deeper technical discussion based on needs but one approach is what is known as an ‘MPLS network’ which routes data between sites without it going out onto the true public internet. This is generally only possible if the same connectivity provider is used at all locations (this is an approach we use for larger and more complex multi-site events) which can have significant benefits.

4. Home based or remote workers will be another challenge as it is expected that far more people will work from home during the Games and many companies do not have capacity for everyone to be connected remotely on a VPN at the same time. The issues above may apply to the home based or remote worker but in addition it is important that the central location has enough internet capacity and infrastructure to deal with all these additional users.

5. We all know what happens to mobile networks at a large event and the situation is expected to be similar during the Games. Yes lots of additional capacity will be put in place but there is only so much the mobile operators can do so it would be wise to assume there will be problems. In the events area it will be much safer to deploy a standalone phone system (VoIP/DECT) which will operate outside of the mobile network. Another aspect to consider is any ‘chip & pin’ payment terminals as many of these operate using the mobile GPRS network which may have issues during the Games. The alternative is Wi-Fi/IP based units which operate over an internet connection – assuming the issues above have been considered!

In summary, it is wise to examine internet provision at locations and at home if it is a critical service as there could well be impacts but with the right planning and service provision these issues can be minimised. For events organisers, especially those organising events in London during the Games period, it is very important that internet access is considered as soon as possible and the right level of provision is made – where in previous years a normal ADSL line has sufficed the risk this year may make it wise to change this to a businesss service which does not have contention issues.

This week sees our 4th consecutive year exhibiting at the Showman’s Show. The show, at Newbury Showground on Wednesday 19th and Thursday 20th October, in a way marks a transition from the 2011 outdoor event season to the start of the 2012 season, although these days we see a variety of outdoor events year-round.

Etherlive ready for it's 4th Showmans Show

Etherlive prepares for its 4th Showmans Show

2012 in the UK is of course a bit of a one off with the Olympics and Paralympics occurring right at the peak of the outdoor event season. We are providing a number of services for Olympic related activity, such as all the IT, communications and broadcast provision for the London Media Centre, but we have been very careful to ensure this has no impact on our existing customers and their events.

What is important though is booking and planning for 2012, especially in London and other locations that will see Olympic activity. Provision of connectivity such as fibre and broadband services will see longer lead times due to sheer demand (we are ordering many services already so that they are provisioned very early next year). Transportation is another area which is impacted with requirements on suppliers to submit transport plans for London well in advance of events if they occur during the broad Olympic period. These aspects and others are all good topics for discussion at Showman’s if you are planning an event in 2012.

This year we are on Stand 71 of the indoor hall where we will be demonstrating a new generation of mobile VoIP handsets – allowing the freedom of a mobile phone with the cost advantages of VoIP. These units also couple up with an alarm and monitoring system providing a new level of integrated service for event organisers.

We will also be launching our latest innovation; Event Band, a suite of tools using RFID technology facilitating payment systems, loyalty services, accreditation and crew management. This technology will sit alongside the latest generation wireless chip & pin PDQs providing reliable payment methods for bars, merchants, exhibitors and ticketing.

The latest networked noise monitoring support offered by Etherlive will be on display, along with a demonstration of next generation satellite broadband, offering internet anywhere from the new KA band with higher internet speeds.

Alongside all the new products we will also have our core network, communications and CCTV technologies on display, solutions that have been used time and time again across a wide range of events connecting thousands of users. Outside we will also have one of our communications tower lights offering CCTV, Wi-Fi and public address as well as an economical lighting system. This can be found on the Aceplant stand (169) at the end of Avenue G.

Recently we announced that Etherlive has joined ESSA (Event Supplier and Services Association), alongside ongoing membership of the AIF (Association of Independent Festivals) and the ASAO (Association of Show and Agricultural Organisations). As well as actively participating in these organisations we also offer special services to fellow members.

We will have plenty of staff on hand to discuss event requirements and provide cost effective solutions to a broad range of connectivity, communications and other event IT needs.

 

Steve Birnage and I were fortunate enough to talk at the HBAA (The Hotel Booking Agents Association) 13th Annual Forum this week on their theme of Future Vision. We based our workshop on the concept of a ‘technology venue’ using each of the various ‘floors’ to represent a technology and how, for example, any service offering (near the top of the building) needs a good foundation at the bottom.

We went on to discuss the many other floors which are all critical for eventually delivering a great customer experience. Attendees where really keen to engage and we got some great questions especially as many are focused on winning business for the 2012 Olympics, opportunities which will have high expectations for connectivity on site. A quick summary of the main points below;

The foundation – High speed, dedicated uncontended internet access is a must. Many venues still attempt to share one connection between rooms, bars and conferencing facilities but this won’t meet many conference organiser requirements these days. We have recently upgraded a London customer with significant bandwidth for their conferencing facilities entirely separate from them having great connectivity for their bedrooms.

Ground floor – A good, reliable wired network which is managed by a third party or venue with appropriate support can make deploying services and performing upgrades later on quite straightforward. Here we were using examples about running fibre between key points in the building (either at design or re-fit) to ensure high speed services can be delivered without causing massive headaches. We used the term ‘managed’ a lot within this section but really the key is to ensure services can be changed quickly remotely.

The Technology Venue

First floor – Reliable Wi-Fi networking. Separate to the internet or network on site it is critical to ensure a wireless network is deployed to deal with the appropriate requirements in mind. For example a conference room which seats 500 needs to have the wireless infrastructure to handle that. New technologies can really help here – like 802.11n mesh wireless networks which can be extended by just plugging in access points which automatically extend coverage however this is dangerous to do unless your environment will automatically minimise interference or you have an appreciation of what channels other access points are using.

Second floor – Make sure you have the support lined up since there is nothing worse than investing and not realising value. Not only should venues have technical support, be it in house or outsourced but also staff should be familiar with the functions and features so they can represent it to customers and prospects who may ask.

Third floor – The critical revenue generation floor – here venues should be thinking past charging for the internet access and looking at sponsored hijack pages, content driven micro sites, support for live streaming and perhaps a strategy about how to re-use customer content in terms of video (perhaps for those who could not attend).

Those key areas got some great interaction from the audience. Many of whom have made significant investment in technology but continue to look for opportunities to maximise return. It was also great to have discussions with several of the larger hotel brands who are committed to contracts and are keen to ensure contracts continue to keep a focus on innovation.

Our latest investment in the new KA band satellite equipment means more flexibility when providing internet connectivity for temporary events.

Satellite internet connectivity can offer significant benefits to customers who are looking for a solution which can be setup in less than 30 minutes and support high speed email and web browsing. The system uses a 0.8 metre diameter dish which needs Southern facing sky to provide download speeds of up to 10 Mbps, similar to a normal ADSL line. The dish communicates with geostationary satellites located in orbit approximately 36,000 kilometres above the equator so is not suitable for all uses but we can advise on where and when satellite works well. Included with the dish and modem is pre-fetch technology which reduces the load time of websites.

In conjunction with Etherlives mobile networking equipment the satellite internet connectivity can quickly be shared out through Wi-Fi networking for press, production crews and exhibitors. In many cases satellite services may be used for first day services followed up with higher speed connectivity as the site builds.

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

Last week in the news much was made of a dedicated satellite launch for broadband Internet access (http://www.bbc.co.uk/news/science-environment-11846237). Satellite Internet access is nothing new and varying levels of service are available today but this launch, along with a couple of others that are planned, do bring additional bandwidth and some improved services. With this in mind I thought it would be useful to cover the good and bad of satellite Internet and whether it can help at your event.  At a high level the pros and cons are as follows:

Pros

  • Relatively quick to deploy at short notice
  • No requirement for any physical wired infrastructure to the site
  • Relatively high bandwidth (primarily download) can be purchased compared to low-end broadband

Cons

  • Requires line of sight (roughly to southern horizon and an associated Fresnel zone area)
  • Requires alignment (although automatic motorised systems are now available)
  • Very high latency (delay)  impacts usability for some applications
  • Can suffer weather impacts such as rain fade
  • Higher bandwidth tends to require a larger dish
  • Tends to work out very costly for longer duration events

For an event organiser some of these points are very important, for example the high latency makes the use of most VPNs virtually impossible which is a real problem if for example you need to run a ticketing system connected via VPN. VoIP services also suffer with high latency meaning delays and ‘Darlek’ effects. There are some improvements with the latest generation services but the simple fact is that satellites are a long way away and will always suffer high latency. It is also important to not assume a satellite dish will have line of sight – there are many situations where getting visibility to the southern horizon is harder than expected and it is also import to factor in the Fresnel zone, this effect means that a small gap between two buildings or trees may not work as expected.

Not all satellite services are the same. Different satellites have different ‘footprints’ meaning they cover different parts of Europe. Many providers also use contention ratios on satellite services too in a similar way to wired ADSL/Broadband services. There are a range of speed options ranging from consumer type services up to more business/professional levels, some services are also optimised for digital video links rather than web browsing.

So, in summary, when should you use satellite? When there really are no other options. We can, and do use satellite from time to time but it is the last resort and requires careful planning to ensure the service delivered meets the requirements. We always work with customers to review all options and recommend the most appropriate solution.

As the outdoor events season quietens down a bit and focus moves to planning for 2011, I thought it would be useful to list out some of the trends we have seen during 2010 which can help with 2011 planning when it comes to IT and communications at event sites. Although focused on outdoor events most of the topics below apply equally to indoor events. So here we go:

  1. Plan and Book early – Connectivity providers have a few terms they love to use to push up costs – survey and expedite being two common ones. These costs mount rapidly and can generally be avoided by early engagement and planning. Last minute installations can end up being 2 or 3 times the cost of a normal installation. Other things to watch for include the ‘miscellaneous labour charges’, which often appear if a provider has to run cables around a site. This can be minimised by agreeing ‘demarcation’ at a suitable location and then cables being run by the event itself (we do this at most event sites and it can save £1,000s for larger deployments)
  2. PDQ / Payment Systems – In 2010 we have seen a significant rise in the number of events reporting problems with GPRS (mobile phone) PDQ machines – these are the credit/debit card machines used for merchandise, box offices, traders, etc. The problem stems from the fact that at events the mobile networks (Vodaphone, O2, Orange, etc) cannot handle the amount of data that users are trying to pull over the network, and with all the network congestion the PDQ machines cannot process transactions. The reason the problem is getting worse relates to the increase in smartphones using more data and also some reluctance by operators to put in temporary masts due to their high cost. However it is important to note that just because a temporary mast is installed is does not necessary mean that data services will be any better as most temporary masts are more for the benefit of voice calls. The alternative to GPRS PDQs are Wi-Fi PDQs – exactly the same machines but using a Wi-Fi network instead. Obviously this requires a Wi-Fi network to be in place but it means the network is fully controlled and transactions on the machines are much faster. There are options to rent Wi-Fi PDQs (we offer this service) but 2-3 weeks notice is required as the machines have to be configured with the relevant banking merchant id.
  3. VPN for Ticketing Systems – VPNs (Virtual Private Networks) are a method for creating a secure connection between two locations such as an event site and a central database somewhere. They are often used by ticketing and stock systems which are increasingly being used from event sites. There are two things to watch for, firstly VPNs require good network connectivity, especially upload, which means basic broadband will not support it very well. The second area is that VPNs often require special firewall configuration, particularly if multiple VPNs are to be used.
  4. Wireless Spectrum Management – The use of wireless equipment on event sites continues to grow at a pace – general Wi-Fi, CCTV, ticket scanning, sound systems, audio and video links, etc. all make use of wireless solutions, many of which operate in the same frequency range. Harmony and reliable operation can only be achieved if everyone works together and early communication and coordination is key to ensure there is no interference.
  5. Smartphone Hunting – The rapid increase in smartphone devices with Wi-Fi creates new challenges for onsite networks, even when the event network is not intended for public access. The issue is that smartphones will continually ‘hunt’ for Wi-Fi networks and when they find one they try to connect. This creates a small load on the network whilst they negotiate a connection (which will eventually fail if the network is secure) and with enough devices trying to connect this load builds up to the point where it impacts real users. The solution involves using wireless equipment designed for larger loads coupled with proper network management as low end Wi-Fi routers are not designed to deal with large numbers of users.
  6. VoIP Phones – The use of VoIP phones at events is now commonplace and demand is growing as more people become frustrated with mobile networks at events. Use of VoIP is the best way to avoid having multiple BT lines and the only way to have a flexible solution allowing last minute deployment of additional phones.
  7. Smartphone Apps – More and more events are now commissioning their own apps for use at events but few events are considering the full picture which is critical for success. Most of these applications (certainly the more useful ones) require connectivity at the event to get updates. Typically the mobile networks struggle with demand at events and so the user gets a poor experience and rates the app badly. Many users also turn up at the event expecting to download the app which creates further (significant) demand. One way around this is to provide a locally controlled Wi-Fi network for use by the app. This can then also be used to deliver local content direct from the site.
  8. Public Wi-Fi Access – The increase in smartphones coupled with the massive expansion of publicly available Wi-Fi leads to more and more expectation that events will have Wi-Fi access. The costs of expanding an existing network being provided to site production, technical production, crew etc is not as high as people initially think and opens new avenues for sponsorship, advertising and rich content delivery.

As always, whether you a run a small event or a large event, we are always happy to provide advice, support and services to your event to ensure technology does not get in the way of delivering a great experience.
