Major forms of wireless communication are Satellites, Near Field Communications (NFC), Infrared (IR), Cellular Connectivity, Wireless networking, WiMax, Li-Fi, Wi-Fi and Bluetooth LE (BLE). Perfect examples of wireless devices can be cordless telephones, GPS units, wireless computer parts, satellite television, ZigBee technology and many more. Understandably, they don’t need wires to send signals, and hence can communicate from even remote areas. Wireless communication technology has evolved to be an integral part of communication devices, no matter what they are used for. There are so many communication technologies around, so which one should you use? The idea is to create user-friendly devices that can make lives easier, so the choice of technology is very, very important. This brings us to topic of wireless communication. Other interesting things on the show were rollable LG OLED TV, ultra-thin laptops, Google Assistant, Amazon Alexa, smart thermostats & light bulbs, Internet-connected garage door openers, GoPro cameras, and new Sony smartphones. The best in the show winner was The Wall by Samsung, while the People’s Choice was HTC Vive Pro. In CES 2018, we were introduced to the newest versions of groundbreaking technology. Many of them are revealed through events like CES, the show that reveals to the world what the tech world has been up to. Big players have already staked their claim in the most lucrative of all consumer markets, but there is still tremendous potential for new players.Įach year, innovations in the field of IoT have made it more exciting than ever. The leading IoT areas are transportation/automotive, healthcare, smart home appliances, retail and wearables. The players who use this technology to come up with their best products will benefit themselves a great deal, and move miles ahead of the competition. It's up to you to work out the best balance of latency, range and expense.The IoT technology industry has grown so huge that it has established itself as the king of technology in every business and industry. Given these statistics, they fall well within 2ms latency for triggering, suitable for your application, and they use very little power. This decreases to 444µs on 1Mbps mode and 283µs on 2Mbps mode.

I would recommend using one of these for the referee's button at least, depending on the range you need.Īccording to Charles Hallard of, The non-amplified chips can get 30m line-of-sight range in 250kbps mode, and I have verified this in my own testing.Īccording to user sporadic on, sending a 32 byte payload in 250kbps mode takes 1432µs from the start of Tx mode on the transmitter to receiving the full message on receiver. Versions with an RP-SMA antenna connector and an advertised range of up to 1000m are also available for about $5 each. They also have built-in mesh networking modes which may or may not be of use. RF24, Mirf, RadioHead) and tutorials for using the modules (see ).

There are multiple Arduino libraries (e.g. The range decreases accordingly with higher bitrate, but the time spent sending a message does too. They have 3 modes of transmission: 250kbps, 1Mbps, and 2Mbps.

I've used NRF24L01+ chipset 2.4GHz wireless modules with Arduino before, and found them to be great, and super cheap (~$10 for 10 of them on ebay!). So, did I miss anything? I appreciate any guidance. Pros: zero lag since it's all electromechanical, no dataĬons: multiple buttons at the same frequency won't work

Pros: dunno, cost seems to be a bit smallerĬons: multiple buttons at the same frequency will probably create a lot of noise Pros: 2ms latency (I justed pinged my wi-fi router), dozens of buttons if need be Pros: 3-6ms latency (advertised), low energyĬons: cost, not more than 7 buttons to the device SO, what would be the optimal wireless tech to use? Please share your experience from similar projects (or just theoretical knowledge :) Here's what I researched so far (correct me if I'm wrong): I cannot have players shouting "my button is laggy!" On the other hand, I don't want to use more expensive/complex tech than needed. Since the best quiz players can click a button within 10ms of the signal, it is very important that there is a very, very little variance in ping between different buttons. I want all buttons (referee's + X players) to be wireless. The first to push wins the right to give an answer. I am drafting a pub quiz project, where the Referee gives a signal and multiple players push their buttons.
