Wireless connection not found

Wireless cannot be seen, but please note that I cannot find it. This is another problem that many wireless users often encounter during their use.

After I have finished my meal at a pizza shop, I plan to use my credit card to settle the bill. The cashier's lady took out a hand-held wireless card reader and told me that this was a special service provided by the store to facilitate the use of credit cards.

However, the problem is coming soon. My location may not be well covered, so the lady had to keep this little device in the air and find a wireless network in different locations. This behavior made many people around me laugh. I really don't know whether the special service they mentioned just now refers to wireless checkout or the special "dance.

This reminds me of the wireless network deployment problem. Wireless can indeed bring freedom and convenience to our lives, but a wireless environment with poor coverage will become a "messy" network. The Wi-Fi Alliance and many wireless device manufacturers hope to rely on the multi-entry and extra-large-value wireless transmission technology provided by the next generation 802.11n standard. They hope to use this technology, provides better transmission speed and coverage for wireless networks.

I fully agree with this method to solve the current bottleneck of wireless network applications through continuous technical upgrades. However, we have to admit that most of our focus today is on wireless speed, bandwidth, and security. But what if that happens? Is there a simpler and more direct approach? If adequate survey design and actual environment application testing are not completed before deployment, I think the "Special Service" mentioned above may come to each of us. When I interviewed a senior Wi-Fi Alliance official last time, I once heard of him saying that wireless networks will add mandatory testing policies for security and transmission stability in the future, but isn't it necessary to add mandatory terms for field testing prior to wireless deployment? The benevolent sees benevolence, the wise sees wisdom!
