Topper Advertising Car Top Taxi Led Display Testing By Electronic Nissan Leaf In Ukraine
In Ukraine, out client is having his new Car-top led display tested. Taxi topper advertising is very popular in Eastern European countries. Now I shall offer reply to our client in Ukraine one by one:
Q1: You told me yesterday during our conversation in ‘Whatsapp’ that current LED taxi top doesn't support 3G connection, and works only with CDMA. But earlier you told me that it works with 3G too. Actually it also was in your commercial proposition (the screen hot is attached). Could you please explain this moment one more time to me?
Reply: Thanks for your feedback. Our control card supports 2G/3G/4G CDMA networks and TD-SCDMA networks. The digital taxi topper advertising led display you had purchase from us has the edition that supports CDMA NETWORKS. The control card can’t support CDMA and TD-SCDMA at the same time.
Q2: We also want to make the Wi-Fi spot in the car. So we want to use the income internet also for Taxi customers. What do you think about this?
Reply: Purchase our taxitops with WiFi edition control cards;
Our control cards are divided into two types, according to their functions:
I. 3G/46 function, U-disk function, cable connected; www.sheenled.net Cloud Platform;
You can send advertising contents via the above four methods;
II. WiFi function, U-disk function, cable connected; www.sheenled.net Cloud Platform;
You can send advertising contents via the above four methods;
Q3: I need extra instruction of downloading the content. How many ways do I have? Wireless? Through Wi-Fi? Through USB? Maybe by inserting SD card? Or all of them?
Reply: In China, a lot of Advertisers choose to cooperate with Telecom Companies to make money from mobile advertisements. You may ask why. Now I explain it to you: If you self purchase 3G/4G wireless router and sim card service from the local telecom firms, the data that the taxi customers download of upload may be very huge. In China, mobile data is pretty expensive. Then, for instance, bus mobile advertisers cooperate with local telecom firms. Local telecom firms provided the equipment and the data for the mobile bus. When bus customers access to the WiFi spot on the bus, they have to see one or two or some ads before they success in getting on the mobile internet.
Q4: We want to start this project on electro taxis (Nissan Leaf). What we have to do? Do we have to install extra battery in the car? Or maybe you have some tips.
Reply: all of them except SD card;
Q5: What price I'll get in case I'll order 50+ units?
Reply: For the price, I shall send you another email to discuss it with you later in the afternoon.
