LP-CC1352P7: Different between LP-CC1352P7-1 and LP-CC1352P7-4

Hello TI,

I would order LP-CC1352P7-1 to apply for Wi Sun network. However, I can not find LP-CC1352P7-1 on TI website, just LP-CC1352P7-4. 

Idk the different between CC1352P7-1 and CC1352P7-4. Just found

• LP-CC1352P7-1: 868/915 MHz up to 20 dBm, 2.4 GHz up to 5 dBm
• LP-CC1352P7-4: 433 MHz up to 13 dBm, 2.4 GHz up to 10 dBm

So It means LP-CC1352P7-4 can not support for Wi-Sun network (border router and node router) ?

Hope to see response.

Thanks,
