development area network

so actually 8:02

Standish committee defaults and

maintained it working standards and

community practices body then maintain

oil area networks

you

standards and in known technology they

are using so the wireless personal

alienate or also known as it of your pen

are using the I Triple E standards that

it's a are typically 802.15 point when n

this technology is known as a Bluetooth

and the other is low rate of wireless

personal area network

that is using the I Triple E 802.15.4

standard of the I 2802 and this

technology is known as ZB the other is

the wireless local area network w9 so i

w link and this is using the I Triple E

if your standards as e 2.1 one standard

of the ith co2 and this is called least
