求翻译：ESS是由多个BSS通过DS联结形成的一个扩展区域，其覆盖范围可覆盖数公里。对于ESS网络可能出现如BSS可部分重叠、各个BSS在物理上可以使非连接的、BSS在物理上可以并列排列在一起以增加冗余度等可能。是什么意思？

ess ds links formed by a number of bss by an extended region, and its coverage can cover several kilometers. Ess network bss can partially overlap each bss physically disconnected the bss physically side by side may be arranged together in order to increase redundancy.

ESS is an extension by the formation of multiple BSS by DS connection area, its coverage may cover several kilometers. ESS network may appear as overlapping the BSS section, each BSS physically can make non-connection and BSS physically can be arranged side-by-side together to increase redundancy, e
