Singtel will launch its nationwide mobile internet of things (IoT) network by the end of September 2017.
The network uses the CAT-M1 and NB-IoT platforms that run on 4G Long Term Evolution networks.
Parameter
|
CAT-M1 (CAT-M)
|
NB-IoT
|
Bandwidth
|
1.4MHz
|
200KHz
|
Modes of Operation
|
In-band
|
In-band, Guard-band, standalone (GSM bands)
|
Duplex Mode
|
HD-FDD / FDD / TDD
|
HD-FDD (TDD under discussion)
|
Peak Data Rate
|
375Kbps (HD-FDD), 1Mbps (FDD)
|
~50kbps for HD-FDD (not decided yet in 3GPP)
|
UL Transmit Power
|
23dBm 20dBm
|
23dBm, lower power under discussion
|
VoLTE support
|
Will be supported
|
Not supported
|
Mobility support
|
Full mobility support
|
No connected mobility (only idle mode reselection)
|
The IoT network will support devices with battery life of up to 10 years or more. A distinguishing feature of Singtel’s cellular IoT over CAT-M1 network is that it enables businesses to make VoLTE calls in future using small portable devices with long battery life, such as wearables and trackers with voice capability, SingTel notes.
