9th October 2019: Telstra 3G shutdown in June 2024 will not affect the Icom IP501H as its 3G coverage on Telstra is already practically non-existent as the required frequencies are not supported.

The Icom IP501H is a device which operates just like a portable radio, but using the mobile network. There are many benefits of a device like this, but the Icom IP501H has some critical technical pitfalls for use in Australia, despite the fact that it is a solid PTT device


If you don't have time for the finer details, the maps above pretty much sum it up. Whatever PTT system, UHF or VHF radio network, Icom LTE radio, PTT or PoC device you are investing in, check the specs and do thorough testing before you buy, and make up your own mind on the coverage and performance for your needs.


Frequency issues which severely limit Icom IP501H operation and coverage in Australia:


1. The Icom IP501H does not support LTE Band 28, which is the lower 700MHz frequency, crucial for coverage and performance. Band 28 LTE is used by both Telstra and Optus. Band 28 is Telstra's most important LTE frequency band, and first mandatory LTE band for approved equipment.


2. The Icom IP501H (export/Non-USA version) does not properly support the Telstra network.

  a. Icom IP501H (non-USA version) does not support Band 5 WCDMA (850MHz 3G). This is the required Telstra 3G band in Australia. The higher frequency 3G bands, which were used in metro areas for extra capacity, are already being phased out completely.

  b. Both Icom IP501H versions (US and export) don't support LTE Band 28, which is the lower 700MHz frequency, crucial for coverage and performance. Band 28 LTE is used by both Telstra and Optus, and is Telstra's most important LTE band. This limits Telstra and Optus Icom IP501H coverage.


3. The Icom IP501H (Export/non-USA version) does not support Band 5 LTE, also limiting Icom IP501H Vodafone coverage. Vodafone's low frequency (high coverage) LTE network is Band 5 (850MHz).


Let's paint a scenario using the Telstra network: the network with the most coverage (on a device supporting the required frequencies).  If the Icom IP501H moves out of the short coverage of the higher frequencies and falls back to 3G, in some metro areas there may still be coverage on the higher 3G bands but this is already being phased out.


In most areas using Telstra, where there is no high frequency 4G coverage, the Icom IP501H will have no coverage whatsoever. The Icom IP501H does not support the required frequencies. The Icom IP501H user is left with limited options, particularly when maximum coverage is required.


If you're using the Icom IP501H in a metro or built-up area, or on Optus, you may be OK (for now, at least). Whatever PTT system, UHF or VHF radio network, Icom LTE radio, or another PTT or PoC device you are investing in, check the specs and do thorough testing before you buy and make up your own mind on the coverage and performance for your needs.
