What are the advantages of small cells?

Small cells provide flexibility and increased QoS capabilities at an attractive cost. Implementing a small cell infrastructure is also more environmentally friendly as it will reduce the number of cell towers (maybe even eventually eliminate them) and it provides a cleaner signal with less power.

Which is better WiFi or cellular?

Generally much faster than cellular, perfect for data-intensive activities (Skype, Netflix, Youtube, downloading music, etc.) Radio Frequencies: Since Wi-Fi is a local area network (LAN), it can only provide internet access within a short-range. … 4G LTE frequencies are a little different than 3G.

What are the disadvantages of a mobile network?

Following are the disadvantages of Cellular Network: ➨It offers less data rate compare to wired networks such as fiber optics, DSL etc. The data rate varies based on wireless standards such as GSM, CDMA, LTE etc. ➨Macro cells are affected by multipath signal loss.

What are the main reasons for using cellular system?

(a) What are the main reasons for using cellular systems? Answer: (4 points) Higher capacity, higher number of the users: cellular systems can reuse spectrum according to certain patterns. Each cell can support a maximum number of users.

How does cellular service work?
