Connected IoT News – March 2018
March has been a month of IoT Network focus, launches and new exciting IoT Ecosystem introductions to the NZ market place.
We will continue to see network operators upgrade their core networks to support the integration of IoT network capabilities and more robust connectivity to meet the rapidly increasing number of connections. We have experienced some of these upgrades at the beginning of this month and we are working with Spark to provide better communication moving forward.
Low-Power Wide-Area Networks (LPWAN) continue to build momentum with new Ecosystem launches and increased network coverage. Yesterday, Spark launched their commercial LoRaWAN nationwide network with 60% coverage and will continue to expand as more Rural and Smart Cities use cases increase and with the availability of LoRaWAN AS923 compatible devices. We will see more information come out on CAT-M1 and NB-IoT which are also technologies that are optimised for IoT communication.
We are excited for many of our customers that have already started or are starting to develop for these new IoT connectivity standards. We will be working with our M2M Connectivity hardware team to provide complete solutions that could help with your initial testing. More to come.
Thank you all for your continued support.
We love helping to simplify IoT and connecting IoT Ecosystems everywhere.

Spark switches on long-range ‘internet of things’ network across New Zealand
Spark announced on Monday that its long-range, low-power network is now available for commercial use in 60% of the places New Zealanders live and work.*
The network uses LoRaWAN™ technology, which carries small amounts of data over long distances, using less power than cellular networks. This makes it ideal for connecting objects far from power sources. For example, to monitor an outdoor car park or an employee working in a remote area.

*Spark LoRaWAN™ coverage:
There is currently coverage in Auckland, Tauranga, Hamilton, Rotorua, Palmerston North, Shannon, Wellington, Nelson, Blenheim, Christchurch, Dunedin. Sites in Hastings and Invercargill will go live in the next few weeks.
What the new network looks like:
Sites consist of a box (gateway) and antenna. Most of these are installed on Spark 4G cell sites, although the LoRaWAN™ network operates totally separate to 4G and other cellular networks. A small number of boxes are installed on third-party sites.
Spark’s LoRaWAN™ Platform (Coming soon from M2M One NZ):
Spark has partnered with Actility for its ThingPark Wireless platform. The Actility platform enables customers to monitor, control and capture information from IoT sensors in a simple and secure way. Spark’s LoRaWAN™ platform and connectivity will be available from M2M One NZ soon. We will keep you updated as this becomes available.

M2M One Control Centre Tips
Control Centre REST API
The Control Center provides a set of REST APIs that allow you to perform essential device monitoring and SMS functions.
The following API functions are available to M2M One NZ Customers.
- Search Devices – Searches for devices based on various filters.
- Get Device Details – Retrieves detailed information for a given device.
- Get Device Audit History – Returns information about changes made to a given device.
- Edit Device Details – Modifies any device attributes such as SIM status, custom fields and other identifiers.
- Get Device Usage – Retrieves usage-related details for a given device.
- Get Session Details – Retrieves information related to the current or most recent session.
- Search SMS – Searches for messages that have been sent or received during a specified timeframe.
- Get SMS Details – Retrieves detailed information about a message.
- Send SMS – Sends an SMS message to a device.

A review of Blockchains
Most have heard about blockchains in relation to bitcoin, but they are not synonymous. Blockchains is the digital ledger technology that underpins bitcoin, but blockchains have functionality far beyond digital currencies.
Perhaps most importantly, it provides secure networking for IoT, because it offers digital transactions that are secure, transparent, auditable and resistant to tampering. Based on non-centralised databases where the ledger of the network transactions (ie. chain) is kept by each node and any transaction is validated across the network. Any one device cannot be tampered with because all devices have a copy of the chain.

Cryptographic algorithms enforce the autonomous, decentralised and trustless networks, and smart contracts determines behavioural rules across the network. A typical blockchain transaction:

So is blockchains posed to take over the world?
Short answer, no. Not yet. The current standard of blockchains are computationally and energy intensive. Blockchains don’t scale well. The bitcoin blockchain can only managed 7 transactions a second, while Visa managed 1667 transactions per second. Ethereum performs slightly better at 20 transactions per second. It simply isn’t suitable for streamlined, large scale networks yet.
Many solutions are being put forward to solve this problem such as side chains, sharding, lightning networks and off-chain state channels, but as blockchains is a decentralised technology, so is the standard.

No organisation owns the standard. A decision on a path forward is going to have to find consensus amongst all parties in this space. However, the advantages of current blockchain technology are still compelling, particularly for compliance-driven networks where the benefits outweigh the scalability problems and computational intensity.
