9.5 Message Type 30, PCTM

Proprietary NMEA message containing the current wireless network (e.g. cellular network, Wi-Fi network)

status.

Note: If used with Store and Forward the network status parameters will be invalid.

Cellular network message format

$PCTM,-xxxdBm,-yyydBm,zzzzz,b,s,r,nnn.nnn.nnn.nnn*hh<CR><LF>

Where:

xxx is the current EV-DO network signal strength, or HSPA network signal strength (firmware version

R1.3.0 and above only)

yyy is the current 1xRTT network signal strength (CDMA only; not available for HSPA where value always

set to -0dBm)

zzzzz is the current System ID (SID) (CDMA only; not available for HSPA where value always set to 0)

b is the band class (CDMA only; not available for HSPA where value always set to 0): 0 = 800MHz, 1 =

1900MHz

s is the service flag:

CDMA: 0 = unknown, 1 = 1xRTT; 2 = EV-DO(revision 0) 3 = EV-DO(revision A)

HSPA (firmware version R1.3.0 and above only): 0 = no service, 1 = GPRS, 2 = EDGE, 3 = UMTS, 4 = HSDPA,

5 = HSUPA, 6 = HSPA+

r is the registered flag: 0 = not registered, 1 = registered.

nnn.nnn.nnn.nnn is the modem's assigned IP address.

hh is the message checksum

Wi-Fi network message format

$PCTM,ttt,essid,ap:ap:ap:ap:ap:ap,txdBm,lq,-rxdBm,-nodBm,nnn.nnn.nnn.nnn*hh

Where:

ttt is the Wi-Fi technology

essid is the ESSID of the access point

ap:ap:ap:ap:ap:ap is the access point MAC address

tx is the TX power

lq is the link quality

rx is the RX signal strength

no is the noise level

nnn.nnn.nnn.nnn is the current IP address of modem's WAN interface
