The R68 in-vehicle 4G router is Meizo's new multiservice communications platform for vehicles. It provides 4G/LTE/LTE-A broadband and Wi-Fi with redundancy and aggregation options, advanced network security mechanisms, and an extended operating temperature range.
Based on a ruggedized hardware design, the router is both vibration and dust resistant and features power surge protection, specific mobile software, dynamic configurations (based on location and communications quality data), and has a delayed power off feature. Furthermore, it provides seamless integration with any third party management tool or hotspot platform.
This high performance platform combines Meizo's CIT software with the latest corporate networking technologies to facilitate service management for large-scale deployments, redundancy, quality of service requirements, access security, and isolation/privacy.
The router CPU is using Broadcom chipset, integrated with industrial grade 4G modem, offering WAN, LAN, SIM, VPN, VRRP, WiFi, and Serial port services, product line supporting the following radio access technologies: LTE, HSPA+, HSPA, UMTS, EVDO, EDGE, CDMA2000, GPRS . By owning automatic connection monitoring and heartbeat detection, make sure the router to be always online.

What is LoRa wireless?
This page covers LoRa wireless technology. This page of RF Wireless World covers LoRa wirelessbasics used in M2M and IoT(Internet of Things).
LoRa stands for Long Range Radio. It is the wireless technology mainly targetted for M2M and IoT networks. This technology will enable public or multi tenant networks to connect multiple applications running in the same network. This LoRa technology will fulfill to develop smart city with the help of LoRa sensors and automated products/applications.
LoRa Alliance formed to standardize LPWAN (Low Power Wide Area Network) for M2M/IoT. The prospective members in this alliance are Actility, Cisco, Bouygues Telecom, Proximus, SingTel, Semtech, Swisscom, IBM, SingTel, KPN etc. The LoRa Alliance will drive global success of LoRa Protocol i.e. LORA WAN.
LoRa wireless technology basics in M2M and IoT
Following table summarizes key features of the LoRa wireless technology such as range, standard, modulation scheme, capacity, physical layer etc.
|
Specification/feature |
LoRa Support |
|
Range |
2-5 Km in dense urban and 15 Km in suburban areas |
|
Frequency band |
ISM band 868 MHz and 915 MHz |
|
Standard |
IEEE 802.15.4g |
|
Modulation |
spread spectrum modulation type is used which uses wide-band linear FM pulses. The frequency increase or frequency decrease over certain period is used to encode data information to be transmitted. It gives 30dB improvement over FSK. |
|
Capacity |
One LoRa gateway takes care of thousands of nodes. |
|
Battery |
Longer battery life |
|
LoRa Physical layer |
Takes care of frequency, power, modulation, signalling between nodes and gateway |
Figure depicts LoRa network. It consists of two main entities such as Sensors (or nodes) and LoRa Gateway(or LoRa base station).
LoRa Products and LoRa device testing
Semtech corporation is leader in LoRa wireless technology based products. LoRa has introduced SX127x family of RF Transceivers for supporting LoRa technology for emerging M2M/IoT market. These transceivers operate in 860-1000 MHz and 137-960 MHz range. They have also introduced concentrator in the 860-1000 MHz frequency range.
Semtech also offers LoRa device evaluation and testing devices for 868 MHz band. LoRa base station is also developed by them. Moreover SemTech corporation has developed LoRa development kit useful for the LoRa development/manufacturing companies.
