Pano pali chitsanzo: Chibokosi cha Bluetooth chikugwirizana ndi piritsi kuti athetse mawonekedwe omwe amatha kufika ku babu yowunikira.
Ndiponso, chosindikiza mu ofesi yaing'ono kapena nyumba yomwe imagwirizanitsa ndi dera lapafupi, laputopu kapena foni imalingaliridwa kukhalapo mkati mwa PAN. N'chimodzimodzinso ndi makibodi ndi zipangizo zina zomwe zimagwiritsa ntchito IrDA (Infrared Data Association).
Zopeka, PAN ikhoza kukhala ndi zipangizo zing'onozing'ono, zovala kapena zomangika zomwe zingathe kuyankhulana pafupi ndi zipangizo zina zopanda waya.

Ngakhale PANs, mwakutanthauzira, munthu, angathebe kulumikiza intaneti pazinthu zina. Mwachitsanzo, chipangizo mkati mwa PAN chingagwirizanitsidwe ku LAN yomwe imatha kupeza intaneti, yomwe ndi WAN. Momwemonso, mtundu uliwonse wa makanema ndi wochepa kuposa wotsatira, koma onsewo angathe kugwirizana kwambiri.
Ubwino wa Network Personal Network
PAN ndizogwiritsira ntchito payekha, kotero mapindu angakhale omveka bwino kuposa pamene akuyankhula za ma intaneti ambiri, mwachitsanzo, omwe akufotokoza intaneti. Ndi malo ochezera a pawekha, zipangizo zanu zomwe zimagwirizanitsa zingathe kuyanjana kuti zikhale zosavuta kuyankhulana.
Mwachitsanzo, chipinda chochita opaleshoni kuchipatala chikhoza kukhala ndi PAN yomwe ilipo kuti dokotalayo athe kuyankhulana ndi mamembala ena mu chipinda.

Chitsanzo china chomwe tafotokozedwa mwachidule chiri ndi keyboard yopanda waya kapena mbewa. Sakusowa kugwiritsa ntchito makompyuta kumalo ena kapena mizinda ina, choncho m'malo mwake amamangidwanso kuti azilankhulana ndi chipangizo choyandikana nacho, chomwe chimakhala chowoneka ngati kompyuta kapena piritsi.
Popeza kuti zipangizo zambiri zomwe zimathandiza kulankhulana kwafupipafupi zingalepheretse kugwirizana komwe sikuli kovomerezeka, WPAN imatengedwa kukhala otetezeka. Komabe, monga momwe zilili ndi WLAN ndi mitundu ina ya maukonde, malo amtundu waumwini amapezeka mosavuta kwa osokoneza pafupi.
