“…2, where the channel bandwidth is 10 MHz, and the first channel (Channel 172) starts at 5.855 GHz [2]. Channel 172 is designated exclusively "for vehicle-to-vehicle safety communications for accident avoidance and mitigation, and safety of life and property applications" [9].…”

“…The maximum channel bandwidth of 802.11 at 5 GHz has increased from 20 MHz in 802.11a to 40 MHz for 802.11n and to 160 MHz for 802.11ac. Since 802.11ac has much wider channel bandwidth and is expected to be deployed in billions of devices in years to come, channel congestion becomes a big concern [2]. In response to the concern, the FCC issued a Notice of Proposed Rulemaking (NPRM 13-22) in early 2013 that proposed adding 195 MHz of additional spectrum in 5 GHz for use by unlicensed devices such as Wi-Fi.…”

“…The current and new channels proposed by NPRM 13-22 for 802.11ac at 5 GHz are shown in Fig. 3 [2]. As shown in the figure, the newly added channels between 5825 and 5925 MHz for 802.11ac overlaps with the frequency bands (5850-5925 MHz) used by DSRC, which imposes coexistence issues.…”

“…As shown in the figure, the newly added channels between 5825 and 5925 MHz for 802.11ac overlaps with the frequency bands (5850-5925 MHz) used by DSRC, which imposes coexistence issues. In addition to the concern that sharing bandwidth with unlicensed devices could compromise the safety applications DSRC intends to offer, there are also coexistence technical challenges that must be overcome [2]. The technical challenges include the channel bandwidth and power level for CSMA/CA channel access being different between 802.11p and 802.11ac.…”

“…In the early 2013, as response to the rapid popularization of Wi-Fi devices, the FCC issued a Notice of Proposed Rulemaking, numbered [13][14][15][16][17][18][19][20][21][22], which suggests appending an additional 195-MHz bands in 5 GHz to be allowably operated by the unlicensed Wi-Fi devices [9]. As a result, the FCC and the automotive industry has come to an agree to test sharing the DSRC spectrum, so that Wi-Fi and DSRC devices might share the same space in near future and Wi-Fi's speed and capabilities can be easily boosted.…”

The Notice of Proposed Rulemaking 13‐22 released by Federal Communications Commission unlocks the Dedicated Short Range Communication (DSRC) spectrum for Wi‐Fi availability, which undoubtedly brings unpredictable effects to the new‐emerging vehicular applications and services. To efficiently harmonize the spectrum operation between DSRC and Wi‐Fi networks, several dynamic spectrum‐sharing schemes are already proposed to improve the spectral efficiency over a limited bandwidth situation and as well to satisfy the ever‐increasing demand for bandwidth resource. Different from most previous literature that mainly focused on the performance analysis of cellular‐network‐centric spectrum sharing, we aim to analyze the performance of the mainstream dynamic spectrum‐sharing schemes specially designed for the coexistence of DSRC and Wi‐Fi networks against various combinations of network parameters through a hybrid network model and performance indicators. We employ the Poisson point process to model a hybrid network where DSRC vehicles and Wi‐Fi devices coexist, and introduce the performance indicators of spectrum efficiency and data rate to assess the utility of different spectrum sharing candidates. Through the presented hybrid model and performance indicators, we collect extensive numerical and simulation results to investigate four typical spectrum allocation schemes for DSRC and Wi‐Fi coexistence, that is non‐sharing scheme, original sharing scheme, and Qualcomm's and Cisco's proposals, respectively. The results show that the dynamic spectrum sharing in the 5.9‐GHz band can significantly raise the performance of Wi‐Fi network without excessively degrading the DSRC system, and especially the Cisco's proposal prefers to protect the DSRC profit while the Qualcomm's draft favors Wi‐Fi exclusively.
