Detailed Description

Implementation of the LinkAdrReq LoRaWAN MAC command.

With this command, the network server can request a device to change its data rate, transmission power and the channel it uses for uplink transmissions.

Constructor & Destructor Documentation

◆ LinkAdrReq() [1/2]

ns3::lorawan::LinkAdrReq::LinkAdrReq ( )

Default constructor.

Definition at line 196 of file mac-command.cc.

References ns3::lorawan::LINK_ADR_REQ, ns3::lorawan::MacCommand::m_commandType, ns3::lorawan::MacCommand::m_serializedSize, and NS_LOG_FUNCTION.

◆ LinkAdrReq() [2/2]

ns3::lorawan::LinkAdrReq::LinkAdrReq	(	uint8_t	dataRate,
		uint8_t	txPower,
		uint16_t	chMask,
		uint8_t	chMaskCntl,
		uint8_t	nbTrans )

Constructor with given fields.

The parameters of this constructor are serializable fields of the MAC command specified by the LoRaWAN protocol. They represent MAC and PHY layer configurations to be applied by the receiving end device. See, [LoRaWAN® L2 1.0.4 Specification (TS001-1.0.4)] and [LoRaWAN® Regional Parameters RP002-1.0.4] for more details on how the fields are used and which physical values they stand for.

Parameters

dataRate	The DataRate field to set.
txPower	The TXPower field to set.
chMask	The ChMask field to set.
chMaskCntl	The ChMaskCntl field to set.
nbTrans	The NbTrans field to set.

Member Function Documentation

◆ Deserialize()

uint8_t ns3::lorawan::LinkAdrReq::Deserialize ( Buffer::Iterator & start )

overridevirtual

Deserialize the buffer into a MAC command.

Parameters

start A pointer to the buffer that contains the serialized command.

Returns: The number of bytes that were consumed.

Implements ns3::lorawan::MacCommand.

Definition at line 234 of file mac-command.cc.

References m_chMask, m_chMaskCntl, m_dataRate, m_nbTrans, ns3::lorawan::MacCommand::m_serializedSize, m_txPower, and NS_LOG_FUNCTION.

◆ GetChMask()

uint16_t ns3::lorawan::LinkAdrReq::GetChMask ( ) const

Get the 16 bit mask of enabled channels.

Returns: The 16 bit channel mask.

Definition at line 276 of file mac-command.cc.

References m_chMask, and NS_LOG_FUNCTION.

◆ GetChMaskCntl()

uint8_t ns3::lorawan::LinkAdrReq::GetChMaskCntl ( ) const

Get the ChMaskCntl field, used as an indicator of the 16-channel bank to apply the ChMask to.

The interpretation of this field is region-dependent.

Returns: The ChMaskCntl field.

Definition at line 283 of file mac-command.cc.

References m_chMaskCntl, and NS_LOG_FUNCTION.

◆ GetDataRate()

uint8_t ns3::lorawan::LinkAdrReq::GetDataRate ( ) const

Return the data rate prescribed by this MAC command.

Returns: An unsigned 8-bit integer containing the data rate.

Definition at line 262 of file mac-command.cc.

References m_dataRate, and NS_LOG_FUNCTION.

◆ GetNbTrans()

uint8_t ns3::lorawan::LinkAdrReq::GetNbTrans ( ) const

Get the number of repeated transmissions prescribed by this MAC command.

Returns: The number of repeated transmissions.

Definition at line 290 of file mac-command.cc.

References m_nbTrans, and NS_LOG_FUNCTION.

◆ GetTxPower()

uint8_t ns3::lorawan::LinkAdrReq::GetTxPower ( ) const

Get the transmission power prescribed by this MAC command.

The MAC layer is expected to translate this value to a certain power in dBm when communicating it to the PHY, and the translation will vary based on the region of the device.

Returns: The TX power, encoded as an unsigned 8-bit integer.

Definition at line 269 of file mac-command.cc.

References m_txPower, and NS_LOG_FUNCTION.

◆ Print()

void ns3::lorawan::LinkAdrReq::Print ( std::ostream & os ) const

overridevirtual

Print the contents of this MAC command in human-readable format.

Parameters

os	The std::ostream instance on which to print the MAC command.

◆ Serialize()

void ns3::lorawan::LinkAdrReq::Serialize ( Buffer::Iterator & start ) const

overridevirtual

Serialize the contents of this MAC command into a buffer, according to the LoRaWAN standard.

Parameters

start A pointer to the buffer into which to serialize the command.

Implements ns3::lorawan::MacCommand.
