27 May How does 5g work?

With 5G, signals run over new radio frequencies, which requires updating radios and other equipment on cell towers. There are three different methods for building a 5G network, depending on the type of assets a wireless carrier has: low-band network (wide coverage area but only about 20% faster than 4G), high-band network (superfast speeds but signals don’t travel well and struggle to move through hard surfaces) and mid-band network (balances speed and coverage).

Carriers building superfast 5G networks must install tons of small cell sites — about the size of pizza boxes — to light poles, walls or towers, often in relatively small proximity to one another. For that reason, superfast networks are mostly being deployed city by city. Eventually, most US carriers will have a mix of the different network types that will enable both broad coverage and fast speeds.

Just how fast will download speeds be?

Just how fast will download speeds be?

The fastest 5G networks are expected to be at least 10 times faster than 4G LTE, according to wireless industry trade group GSMA. Some experts say they could eventually be 100 times faster. That’s fast enough to download a two hour movie in fewer than 10 seconds, versus around 7 minutes with 4G. Actual download speeds will depend on a number of factors, including location and network traffic.

How can you use it?

In order to connect to and get the benefits of a 5G network, consumers have to have 5G-enabled devices. Samsung, Motorola, Huawei, LG, OnePlus and several other device makers have released 5G phones. Apple is widely expected to release a 5G iPhone later in fall 2020. Some companies — including manufacturers and the NFL — are also working with carriers to install personal 5G networks so they can reap the benefits without waiting for the nationwide rollout.

Are there drawbacks?

Significant adoption of 5G is going to take years — industry trade group GSMA estimates that by 2025, around half of mobile connections will be 5G (the rest will be older tech, like 4G and 3G). There are also concerns among regulators and others about the security of 5G, especially since crucial technologies such as self-driving cars and healthcare systems will be built on top of the network.
