4G can be best described in one word “MAGIC”, which stands for Mobile Multimedia Anytime Anywhere Global mobility support, Integrated wireless and Personalized services.
2.5G or EDGE as it was known came next. Edge was essentially the same technology as GPRS, but it was kind of duplexed across multiple channels, so this meant you could see speeds of up to 400kbps in theory. However the real change in 2.5G came about in how it worked.
EDGE (also known as Enhanced GPRS or EGPRS) is a data system used on top of GSM networks. It provides nearly three times faster speeds than the outdated GPRS system. The theoretical maximum speed is 473 kbps for 8 timeslots but it is typically limited to 135 kbps in order to conserve spectrum resources.
4G LTE vs.Verizon 4G LTE wireless broadband is 10 times faster than 3G — able to handle download speeds between 5 and 12 Mbps (Megabits per second) and upload speeds between 2 and 5 Mbps, with peak download speeds approaching 50 Mbps. Cable speeds vary, but 4 to 12 Mbps are common.
A 4G WiFi router, containing a built-in LTE broadband modem, uses a SIM card to share internet connections. You can use a 4G WiFi router for internet sharing anywhere, as long as it is within the network range of the network service provided by your mobile operator.
TeliaSonera branded the network "4G". The modem devices on offer were manufactured by Samsung (dongle GT-B3710), and the network infrastructure created by Huawei (in Oslo) and Ericsson (in Stockholm).
7G (seventh-generation wireless) is the inevitable intelligent cellular technology. 7G networks will be able to use higher frequencies and provide substantially higher capacity and much lower latency in communications.
How does 4G work? Using high-speed upload and download packets, 4G provides customers with access to broadband-style speeds from their mobile device, tablet or laptop. It is basically a radio system, with masts broadcasting 4G signals across the country.
The Home Subscriber Server (HSS) is a key element of LTE and IMS core networks; it is a master user database that is stored in one single node. It allows Communications Service Providers (CSPs) to manage customers in real-time and in a cost-effective manner.
Mobility Management Entity(MME) is a key component of the standards-defined Evolved Pack Core (EPC) for LTE. It provides mobility session management for the LTE network and supports subscriber authentication, roaming and handovers to other networks.4g iot module
