不要急着回答；我想你们都在IEEE或类似的机构工作。或者你们都是工程师。或者你们都没有真正的家庭自动化，只需要几个月的时间…
以上来自于百度翻译 以下为原文 ...don't rush at replying ;) :D I suppose you all work at IEEE or alike. or you're all engineer. or you all have no real house automation. just some more months to go... |

达里奥，为了了解MiWi Mesh操作，我尝试了MiWi和WiFi的结合，并通过互联网连接多个MiWi网状网络来检查是否能够创建大范围的覆盖。为此，我用MRP24J40制作了一个板，PIC16F6。7K22和MRF24G0MA和一个只有MRF24J40和PIC67 K22加上一些I/O的第二板实现了一个最小的网络并进行了实验，但是由于我没有传输大量的数据，所以我发现WiFi和MiWi之间没有干扰。我的兴趣集中在软件问题上，用于中继信息、处理延迟数据、统一时间保持等。我不关心高WiFi流量的可能共存，因为我的安排并不意味着MIWI网与WiFi区域的共同位置，除了MiWi到WiFi桥站。从我读802.15.4所理解的，2.4 GHz不是唯一可以与O-QPSK一起使用的频带。除了Microchip的MRF24J40之外，不同的设备可以在其他可用频带之一上工作，只要这种设备是市售的。这可能会解决你的问题。我有一种感觉，微芯片本身对MRF24J40不太满意。
以上来自于百度翻译 以下为原文 Dario, I did play around with combined MIWI and WIFI just for the sake of understanding MIWI mesh operation, and checking the possibility of creating large territory coverage by interconnecting a number of MIWI mesh networks via the Internet. For this purpose I made a board with a MRF24j40, a PIC16F67K22 and a MRF24G0MA and a second board with just an MRF24J40 and PIC67K22 plus some I/O. I implemented a minimal network and experimented, but since I was not transmitting high volumes of data I found no interference between WIFI ad MIWI. My interest were concentrated on software issues for relaying information, handling delayed data, uniform time keeping etc. I was not concerned with the possible coexistance of high wifi traffic because my arrangement was not meant to have the miwi net be co-located with the wifi area except for the miwi to wifi bridge stations. From what I understand by reading 802.15.4 the 2.4 Ghz is not the only frequency band that can be used with O-QPSK. A different device other than Microchip's MRF24J40 could possibly operate on one of the other available bands, provided such device is commercially available. This might solve your issue. I have the feeling that Microchip itself is not very pleased with the MRF24J40. |

我刚查过。显然，AT86RF212B ATMEL转换器可以用于满足您的目的。恐怕这意味着重新设计河流。
以上来自于百度翻译 以下为原文 I just checked. Apparently the AT86RF212B tranceiver by Atmel could be used to suit your purpose. I am afraid it would imply somedriver redesign. |

这是因为在MIWI/ZigBee上使用的服务/协议是未被认可的，所以消息可能丢失。可以使用认可的服务吗？BT也在相同的频谱中。
以上来自于百度翻译 以下为原文 Is it because the services/protocols being used on MiWi/Zigbee are un-acknowledged so the messages can get lost. Could an acknowledged service be used instead? BT is also in the same spectrum. |

我知道，其他频率是可以使用的。但这很有趣…

我避开了5GHz，因为这是另一个流行的家用WiFi频段。我会说使用900兆赫，但它有其他（更不经常）干扰，并取决于你的国家可能或可能不合法。
以上来自于百度翻译 以下为原文 I'd shy away from 5GHz as that's another popular home WiFi frequency band. I would say use 900 MHz, but that has other (much less often) interference, and depending on your country may or may not be legal. |

达里奥，我知道你知道，我很欣赏你把我们的注意力放在这样一个关键问题上，即共同定位无线电服务竞争频带的兼容性。你的帖子总是有用的，即使是有趣的。请不要遗漏架构师，因为我相信他们比工程师低一步（我会把律师放在最下面）。
以上来自于百度翻译 以下为原文 Dario, I knew you knew, and I appreciated you pointed our attention on such a key issue as the compatibility of co-locating radio services competing for band. As always your posts are useful, even when funny. Please do not leave out architects, because I believe they are a step lower than engineers (I would put lawyers at the bottom). |
