It is no less than a nightmare for presenters to stuck amid a meeting or while demonstrating a keynote on stage due to internet failure. Event sponsors and exhibitors are sensitive about the internet connectivity as much of the success of their participation in the event depends on a fast, reliable and uninterrupted event internet service. With the failure of wireless connectivity, the event organizer’s reputation also puts into a stake. The post-conference meetings become fiery with the sponsors and exhibitors bombarding their questions one after another such in a rapid fire round and the exhibitors sitting on the hot-seat has no clear understanding of what went wrong.

To avoid any such unforeseen situation that might turn fatal for your event business, you must consider addressing the following at the planning stage of your event:

To manage wireless connectivity at an event is more complex than to manage a regular office or home internet connectivity. Here you need to do detailed analyses of the space usage, do proper capacity planning and calculate the number of participants at the planning stage itself.

It is always a good idea to include the networking team in all pre-conference meetings. They can help you find potential loopholes at an early stage and let you avoid any mishap during the event.

High-density areas like lobby, keynote and session rooms should be closely monitored; these areas attract more people and the wireless technology also has its limitations. Thus it requires high-density wireless network services in these areas to cater to the needs of the event exhibitors and visitors.

It is also a good idea to educate and pre-inform the attendees about the availability and limitation of wireless connectivity in the event. This will minimize the possibility of internet failure due to heavy user traffic.

Keep tracking different social networking sites for connectivity comments during your event. This way you can track any network malfunctioning at an early stage and take necessary step to make it work properly.

To avoid connection failure, avoid adding complexities to the connection process like sponsor splash screens, password or registration pages. Moreover, these also make your connection slow.

Ask your event internet provider to give a post-event usage report containing useful information that includes bandwidth usage, capacity, number of connected devices etc.

For show organizers, managing the internet services within the venue becomes a really tough job at times, especially when the event is organized on a big scale. However, to enjoy hassle-free management, the organizers can also chose mobile wireless internet services. These pocket-size devices feature high-speed connectivity, multi-sharing options and offer seamless service even during high-bandwidth requirements. Additionally, these lets you free from managing the connection manually as it requires no additional network hardware setup.

Wireless security alarms are becoming very popular in the market today in spite of having some minor flaws. Wired security systems are almost a thing of past now because of all the convenient features that a wireless security alarm has. Wireless systems are easy to install because they are literally without any wires and the fact that they can installed by the owner himself is a very big plus point. Everyone will tell you all the good things about these but here is a brief outline on some of the negative aspects of the wireless ones.

One of the most common problems that wireless security alarms pose is false alarm. Agreed that it can happen with the wired counterpart but its more common in wireless systems. This is because of the fact that they use radio signals to send the transmission from the sensors that are attached on the doors and windows. There is always a possibility of interference from many other appliances in the house that might pull off a false alarm. This problem is now decreasing with the use of more secure radio signals that cant be interfered and usage of alternative signaling mechanisms. Batteries are another minor issue that might trouble you when using a wireless security alarm. You will need to either replace the worn out batteries or recharge them if using rechargeable ones. Since wired systems are all connected, there are generally no issues about batteries at all. So its more about whether you are really lazy or so busy that you have no time to change the batteries or not.

Cost is another minus point with the wireless systems as they are a little more expensive than the older wired ones. This is because wireless security alarms use state of the art technologies and sensors to detect movement or detect an intruder. However, all the good things about the wireless security alarms will make all these flaws look very minor.

All the cons about the wireless systems mentioned here is just to keep you informed and not to push you away from using them. They are any day better than the age old wired security systems that are a mess to maintain, needs expert installation and cant be shifted from one house to another if you are living in a rented place.
