A major difference between LTE and NR in terms of scheduling granularity is that LTE transmission time interval is fixed at 1 ms whereas NR transmission interval is a slot or a fraction of slot whose length is a function of the subcarrier spacing. So one of the methods to reduce the latency in 5G […]

I think It’s not straightforward to determine the optimal RAN topology and associated operation model. There are different parameters will contribute at take a decision like: Existing network footprint. RF Strategy. Operating costs. Device capabilities. Usage Patterns.  The Transport Network is very important as it connects between NG-RAN functional modules and therefore determines which deployment […]

Simply, It is because 3G and LTE have the same clock timing for multi technology handsets. an example. In LTE for BW=5MHz, there is 300 subcarrier {with 10% guard band, 4.5MHz/15KHz=300} But we know that in IFFT/FFT transformation, Nfft should be a power of 2 (to speed-up the FFT operation). 300 is not a power […]

The waveform is a core component of any communication technology. There are two main categories of waveforms:  1) Single-Carrier waveforms like: 2G.  3G. ZigBee. Bluetooth Single-carrier waveforms have a low peak-to-average power ratio (PAPR), which makes them power efficient—suitable for coverage limited scenarios and extending battery life of user equipment. 2) Multi-carrier waveforms.  4G ADSL WLAN […]

In LTE, different types of control information are transmitted inside the control region of physical downlink control channels. But what are these control information? and what are the corresponding channels? Control information and corresponding channels Control Information Physical Control Channel Downlink Control Information (DCI) PDCCH Control Format Indicator (CFI) PCFICH Hybrid-ARQ Indicator (HI) PHICH However, […]

LTE: Is the 4G main technology to deliver data with high throughput and more capacity than 3G. But LTE is IP-Technology (only PS domain). So can’t support the Voice (CS). VoLTE: Is the Voice over LTE, is the way to make Voice calls on LTE but LTE needs to integrate with IMS network infrastructure to […]

The Mobile Telecom field is very wide, mainly you can work in three different companies type: Operator. Vendor. Subcontractor. Also, there’re different domains in the Mobile field, famous for them: Radio. Transmission. Core. IMS. Security. Rollout. Field Maintenance. Customer Experience.
