In New Zealand, the transition from 3G to 4G cutover hardware signifies a significant leap in connectivity infrastructure, especially in urban hubs like the central city. 

When evaluating hardware, it is essential to consider both the expected lifespan and the necessary speed for system upgrades. Some 3G systems have been running for over 10 years without an update. If the goal is to modernise and replicate this deployment time, investing in 5G could be a good idea.

Regardless of use, prioritise networking devices that offer the most robust connectivity. Features like dual-sim, failover, and load balancing are never unwelcome. The choice between 4G and 5G will depend heavily on the solution’s tolerance for latency. Regardless of 5G or LTE, device resilience and remote management ease are important for all modern applications.

Remember, the right replacement hardware isn't just about replacing outdated systems; it's also about preparing for the connectivity demands of tomorrow. Businesses should take time to test different devices to find a good balance between cost, future readiness, and value for their 3G replacement hardware.

Your selection of hardware depends on the connections required. For example, for RS485 connectivity, the Teltonika TRB145 device is the preferred choice, while RS232 connections necessitate the use of a TRB142. In cases requiring multiple I/Os, the TRB141 proves most suitable. This approach ensures that the transition to 4G enhances connectivity and seamlessly aligns with diverse system and application needs.

Should I go straight to 5G?

The decision between 4G and 5G hinges heavily on the solution's tolerance for latency. For those familiar with the robust performance of industrial-grade 5G routers like the Teltonika RUTX50 in New Zealand, the transformative potential of 5G technology is evident. It offers remarkable speed, reliability, and energy efficiency and facilitates significant advancements in IoT capabilities. 

While 5G promises unmatched speed and low latency (5G is much more power hungry than 4G/LTE), it's adoption hinges on specific data transmission requirements. For instance, in scenarios where a single sensor handles data transmission, opting for Narrowband Internet of Things (NB-IoT / CAT M1) over 5G proves more cost-effective due to significant differences in data charges. However, in bustling areas with high-volume, real-time data transmission needs, 5G technology becomes more justifiable, ensuring optimal performance for critical applications. This cutover process demands careful consideration of technological capabilities and economic factors to tailor efficient and cost-effective connectivity solutions to each situation's unique needs.

While there's a natural inclination to upgrade to the latest technology when a network becomes obsolete, the reality is that for most IoT applications, the high speed and low latency of 5G aren't yet essential. However, specific solutions like automation, video streaming, and robotics integration are exceptions where 5G proves invaluable. 

Currently, 4G LTE remains the primary connectivity backbone for most industries throughout New Zealand, and it's likely to remain so for at least another decade. Nevertheless, if there's an anticipation of needing 5G in the foreseeable future, it's prudent to consider upgrading now. Teltonika TRB500 and RUTX50 devices provide access to LTE Cat 20, delivering top-tier 4G speeds even without 5G coverage. These devices serve as excellent choices for both primary and backup internet sources, ensuring preparedness for future technological demands. As the adage goes, it's better to have it and not need it than to need it and not have it.
