u
1. The

shorter batttery life.
2. Response tim
me and antii-lost distan
nce is the ideal value. When wirreless communication
n
environme
,
ent become
e complicate
ed that with
h strong inte
erference, response time will be lengthened
l
anti-loss distance
d
will be a little
e different. If you putt device in the box orr handbag and
a
if yourr
mobile pho
one is with protection shell,
s
it will also influen
nce the com
mmunication distance. Therefore,,
