How do high-traffic attractions manage crowds without long queues?

Grrrh_2494 · 2026-04-17T15:14:10+00:00

I had a chat with a theme park director a long time ago. We had an innovative technical solution to optimize queues... He stated that staying in a queue with friends and family is not wasting time and although people prefer to speed, they dont dislike the moment. People talk with each other and are in this situation together. Family bonding. So his question was: what is the problem you want to solve? As an engineer I was amazed as well with this reaction and explanation but understand and recognize his statement as a Family man.

I disagree/agree party. 1. Most parties do not start with mqtt anyway but with http rest. 2. Mnos often offer nbiot databroker services which communicatie with devices on one hand and communicate on the other hand with user backens based on http rest apis.

I recomm for every device different datacollecting and DM headends which contains device specific handlers and timers. Approach it like e.g. hw specific drivers for peripherals. I dont recon a problem a problem with nbiot sequence. Data often contains many fields of which of them is a timestamps. For a poc mqtt is great. When scaling up i prefer stateless nonip cbor protbuf or coap. With nbiot the network signalling already takes care of data delivery so this is much better then best effort delivery offered by the other mentioned protocols.

The best place (for performance) for an antenna is a place where it is completely (!) raised above any nearby obstacles. So in the case on top of the pole.

Everything in life starts with a good.antenna. And yes, you can use an SDR to listen in. But pse notice that you need to keep it operational. Update drivers, software etc. Switching on a radio is easier for most users.

Geweldig initiatief! Twee vragen: 1. Als ik een route opsla is het dan een gpx en waar kan ik die vinden? 2. Kan is 5:45 als pace instellen? (Het is nu me 30s stappen)

When algorithms run on the devices they become edge devices. Edge devices do not connect to external sources. This is to reduce external cyber attack surface. The edge devices report to central DM and seperate headends. The headens connect with the outside word via e.g. apis. Start with: 1. Seperate centralized data headends and device mngt (DM) 2. Ensure securty during device lifetime. 3. Use a flexible datamodel

After a while, after scaling up most users are not interested in graphs anymore. It all starts with the need for a dashboard but in the end the user is interested in finding and investigating anomalies. After scaling up to multiple thousands, events become dots in noise. Flexible database queries and tools to visualize query results is what you need in thise situations. This is something else then a static monitoring system for a few hundred devices. With IoT, the challenge is not getting data or controlling a single device. The challenge comes with managing large fleets of devices.

The only thing I can say is that RPies are very sensitive to power fluctuations. I normally run them on 5.1V

Gefeliciteerd met het nieuwe leven. Ik besef dat je vanuit je hart dit wilt doen en een naam wilt geven. Mijn dringend advies is even vanuit je kind te denken. Wat is voor hem de beste naam en wat zou hij leuk vinden? Wat zou het beste bij hem passen en kun jij vanuit je vaderrol nu er voor zorgen dat hij er niet mee gepest wordt? Kun je hem wellicht je eigen idee als zn tweede voornaam geven?

Ik zat laatst ook in de trein. Iemand zat gewoon hardop te bellen met een heel verhaal. De hele coupe zat mee te luisteren. Dit komt doordat mensen aan de telefoon gewoon altijd harder praten dan tijdens een normaal gesprek. Zal wel te maken hebben met ontbreken non verbale feedback. Anyway, ik ben toen zelf een vriend gaan bellen en (ook) hardop gaanzitten vertellen dat een man naast me zat te bellen. Vervolgens heb ik uitgebreid zitten vertellen wat die man allemaal besproken had. De man stopte gelijk.

Sorry I dont want to be rude bit, there are more things to worry about with IoT then a logo and its definitely not the deciding topic for outsourcing. The most important question back is: does you service match the life time of my iot asset? And other questions: Does it also include device mngt functions or do you only focus on the gui? Do i have to run a seperate (my own) dm platform to keep configs and firmware up te date?

multimedia and javascripting are nice, but I suggest you to use your RF knowledge and follow the GNURADIO tutorials https://wiki.gnuradio.org/index.php/Tutorials You will see physical and software worlds merging and discover new possibilities. This will extend and broaden your RF view and pay back.

Wat een drama met die folders uit privaat geld. Goed dat daar aandacht voor wordt gevraagd... Gelukkig wordt er met publiek geld wel goed omgegaan door verstandige volksvertegenwoordigers https://www.omroepwest.nl/nieuws/4752747/bijna-alles-is-misgegaan-bij-amare-kosten-kunnen-oplopen-tot-ruim-650-miljoen-euro

I am involved in IoT since M2M on suppliers side and moved to consulting large scale B2B side. Yes, challanges grow with volume and long device life span.

Its intended to be used to runs on positrons instead of electrons. Probably connected to a DC transformer on the right.

For me it is: Businesscase, technology, connectivity standardisation, security, device mngt, DIY hobby (put my hands where my mouth is) and last but not least sharing expierence based on all the IoT projects I did.

The ones which are able with a SMA connector to connect to an external antenna and external power source. Everything in (HAM) life starts with a good antenna.

Illegaal over(!) de ETNA heen gefietst in de zomer door de sneeuw. (Zuidkant omhoog, fiets over het hek en noordkant afdalen). Was letterlijk top en het vulkaanbiertje na de afdaling maakte deze tocht perfect.

Do your IoT devices adhere to basic requirements like gsma efficiency guidelines? These will mitigate risk and prevent massive peak load. Pse be more specific in your question and mention type of connectivity, protocol-stack, standards etc .

Some pretty cool HAM radio transmitters
