Table 2 Numerical parameters for analytical/simulation results

Parameter	Description/value
	Analytical results and basic simulator	3GPP compatible simulator[21]
Macrocellular	Hexagonal layout with BS in the middle of the cell	Hexagonal layout with cell-center BSs
Number of mBS	Infinite for analytical, 19 cell with wrap around for simulations	19 cell with wrap around
Inter-mBS distance	500 m for simulations; 500 m in average for analytical. Therefore, the density of the macrocells (λ_mBS) is $\frac{1}{500 \sqrt{3} / 2} = 4.62 \times 1 0^{- 6} .$ Similarly, the density of femtocells is λ_fBS = λ_mBS × 12 = 5.54 × 10⁻⁵	500 m
Number of fBS	12 per each macrocell	12 per each macrocell
fBs distribution	12 fBSs that are randomly and uniformly distributed within each sector in CSG mode	4 fBSs that are randomly and uniformly distributed within each sector in CSG mode

fBS-fMS minimum distance	5 m	5 m [21]
Bandwidth	10 MHz	10 MHz
DL transmit power mBS	60 dBm	46 dBm, with Tx power at mBS and 14 dBi antenna gain [21]. Three sectors with 3-D antenna pattern. Antenna height, 32 m
DL transmit power fBS	20 dBm	20 dBm with antenna gain of 5 dBi
Thermal noise density	−174 dBm/Hz	−174 dBm/Hz
Path loss model (macrocell)	128.1+40 log₁₀(R), R in km	128.1+37.6log₁₀(R), R in km [21]
