4G Technology disadvantages

Obtaining information from people illegally becomes easier, 4G technology involves the possibility of some interference though not much, It is capable of being attacked (jamming frequencies) and the invasion of privacy increased.

The consumer is forced to buy a new device to support the 4G, New frequencies mean new components in the cell towers, Higher data prices for the consumers, Your current equipment can not be compatible with the 4G network, It has different network bands for different phones  It is expensive and hard to implement.

4G LTE network has higher data prices for the consumers (expensive), The consumers are forced to buy a new device to support 4G LTE, It consumes a lot of battery when in use, It consumes the data very fast and your battery becomes hot when it is used for a very long time (like a microwave).

4G LTE network needs complex hardware, 4G technology is still limited to certain specified carriers and regions but the number of cities that have 4G coverage is increasing by the day, it would take its own time for this network to be available in all the major cities of the world.

Mobiles compatible with 4G network are cheaper than earlier but this new equipment would have to be installed to supply these services, it is a cumbersome process for most mobile carriers planning to launch these services, 4G mobile technology is still fairly new but it will most likely have its initial glitches and bugs, which could be quite annoying for the user.

4G technology uses many antennae and transmitters, You would experience much poorer battery life on your mobile, while on this network, So, you would have to use larger mobile devices with more battery power to be able to stay online for longer periods.

The users would be forced to use 3G or Wi-Fi connectivity in the areas that do not yet have 4G mobile network coverage, While this is a problem in itself, the worse issue is that they would still have to pay the same amount as specified by the 4G network plan, This situation can only be resolved once mobile carriers expand their 4G network coverage to include more regions.

4G technology requires expensive infrastructure for operation, This is embodied in the eNodeBs (Access Points) and mainly EPCs (Gateways or Routers), 4G is optimal for data rates, but not necessarily the best for Voice services, Some of these services are offloaded (delegated) to Wi-Fi or 3G/GSM cellular technologies on your phone.

The Rise of 5G

While 4G has revolutionized mobile technology, it’s gradually being replaced by 5G, which offers even faster speeds, lower latency, and greater capacity. However, 4G still provides reliable and fast connectivity for many users. It’s likely to remain a viable option for several years, especially in areas with limited 5G coverage.
