Bluetooth compatibility which provide support to the Bluetooth

Bluetooth 5 came to market just
over a year ago. It was announced by the executive director of Bluetooth SIG
that the new device would revolutionized the iot. The latest version of the
Bluetooth 5 has much advantages compared to the Bluetooth 4.3 technology such
as longer range, higher speed and extended support for connectionless services.
According to market surveys, the Bluetooth will be used in more than one-third
of all installed IOT devices by 2020. Typical IoT architecture has mainly
physical, communication, software and application layers. Bluetooth is acting
as a communication protocol, which enables devices communicate each other

The Bluetooth 4.x generation
only supported 1Mbps PHY rate, but Bluetooth 5 generation devices have the caliber
to support both 1 Mbps and 2 Mbps PHY rates. The also leads to double the data
transfer between two devices and the studies shows that the current consumption
is also very low compared to older versions of Bluetooth devices. This
improvement effect on the time spent in low-power sleep modes in IoT devices.
The fabulous thing is that Bluetooth 5 devices has the backward compatibility
which provide support to the Bluetooth 4 devices to perform well in IOT.

Bluetooth 5 has the coverage
area by four time than the Bluetooth 4 devices. This means it can cover a whole
house or a building or it can be use in outdoor or commercial applications and
IoT becoming a reality for those areas with the new inventions of Bluetooth 5.
In addition to the 2M PHY, Bluetooth 5 contains two additional optional PHYs
called LE Coded PHYs. This code uses slightly different packet format and it
increases the Rx sensitivity which leads to improve the coverage range. LE
Coded PHYs has a forward error correction(FEC) and Pattern Mapper. It applies
the FEC methodology to correct bit errors upon reception of the packet and
after a pattern mapper is applied to the packet to improve the efficiency of
the communications. The Bluetooth 5 is defined to be +20dBm, while in the
Bluetooth 4 is to be +10dBm. This increases the Tx power by 10x and it should
impact on the coverage range.

One improvement regarding
advertisement(beaconing) is the advertising data sets feature, which allows a
single Bluetooth 5 device to send out multiple individual advertisements data
sets with unique intervals and advertisement data. The new Bluetooth can also
determine a scan request made by a remote device and report to the application
level. The next improvement is that the three advertisements channels which were
using in Bluetooth 4 is there in the Bluetooth 5 for backward compatibility,
but the Bluetooth 5 devices can use remaining data channels as secondary
advertisement channels to broadcast more data which improves the capacity of
the channel. Another improvement is that Bluetooth 5 introduce a periodic
advertising. It allows the transmitter to send out changing beaconing data
periodically and with a fixed interval may receivers can listen to it

By simple Bluetooth 5 contains
many robust features and improve the wireless standard feature. The Bluetooth 5
enabled phones are expected to arrive on the market during 2017 and it need
some time to mature on IoT. More companies are already build chips which
support Bluetooth 5 and it will be a biggest thing waiting to happen in the
